Abstract One new species of Triphleba Rondani and eight new species of Megaselia Rondani are described from Montseny Natural Park (mainland Spain). The new species are Megaselia arbuciensis García-Romera sp.nov., Megaselia barrientosi García-Romera sp. nov., Megaselia callunae García-Romera sp. nov., Megaselia carminis García-Romera sp. nov., Megaselia ivanis García-Romera sp. nov., Megaselia longianalis García-Romera sp. nov., Megaselia montseniensis GarcíaRomera sp. nov., Megaselia sarae García-Romera sp. nov., Triphleba beatricis García-Romera sp. nov. Key words: Diptera, Phoridae, Triphleba, Megaselia, new species, Montseny, Spain
Introduction The scuttle flies (Diptera: Phoridae) of Spain are still poorly known when compared to other European countries such as United Kingdom or Germany, where more than 300 species have been reported. The most recent catalogue of the Diptera of Spain, which includes both mainland Spain and the Canary and Balearic Isles, lists 214 species (García Romera & Baez, 2002). Subsequent additions have cited 22 new records and new species (Disney & Prescher, 2003; Disney & Blasco-Zumeta, 2004; Carles-Tolrà, 2006a,b,c, 2011a,b; Disney, 2006a,b,c, 2009, 2011a, 2012; Disney & Pagola-Carte, 2009; Disney & Franquinho Aguiar, 2010; Disney et al., 2010; Carles-Tolra & García Romera, 2011). The genus Triphleba Rondani includes about 90 species around the world, except the Afrotropical Region (Disney, 1994). 56 species are known in Europe (Disney, 1991; Weber & Prescher, 2013; Carles-Tolrá & García Romera, 2011) and 12 species were listed in the most recent catalogue of Spain (García Romera & Baez, 2002). Subsequent studies have recorded 3 species (Carles-Tolrá, 2006c, 2011b) and have described a new species for this genus (Carles-Tolrá & García Romera, 2011). The giant genus Megaselia Rondani includes around 1500 species, about the half of the known Phoridae. More than 400 species are recorded from Europe (Disney, 1999, 2008) and 155 species have been reported in Spain (García Romera & Baez, 2002) (128 mainland Spain and 55 Canary and Balearic Islands); subsequent additions, including new species and new records, have increased the number in 10 species (Disney 2009, 2011a, 2012; Disney & Pagola-Carte, 2009; Disney et al., 2010). In this paper, nine new species are described, belonging to the genera Triphleba Rondani and Megaselia Rondani.
Material and methods The material were collected by José Antonio Barrientos in Montseny Natural Park (Catalonia, North East Spain), an UNESCO biosphere reserve, between March 1990 and March 1991 using window, water and pitfall traps. Traps were placed in three plots located in a beech (Fagus sylvatica L.) forest. Two plots were located in Montseny (Barcelona), at 1130 m a.s.l. (UTM 31TDG530274) and at 1170 m a.s.l. (UTM 31TDG532273), respectively, while

the third plot was located in Arbúcies (Girona), at 1250 m a.s.l. (UTM31TDG540279). Two additional plots were layed in a Calluna vulgaris (L.) scrubland at 1520 m a.s.l (UTM 31TDG542245) and in a Juniperus communis L. scrubland at 1620 m a.s.l (UTM 31TDG530256 ). The material were preserved in ethanol (70%) and most specimens were subsequently fully dissected and standard slide-mounted in Berlese fluid (see Disney, 1983, 1994). Drawings were made using a Leica Leitz DMRB microscope with drawing attachment. Most specimens are deposited in the Universidad Autónoma de Barcelona (UAB) and some in the private collection of first author (CCG-R).

Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 87, after return of 182, to M. conformis (Wood), but its hypopygium clearly differs from the new species, in the shape of epandrium and development of posterior lobe of hypandrium; the subsequently added M. lactipennis Lundbeck, runs to the same point; it differs from the new species clearly in the hypopygium (development of posterior lobes of hypandrium, shape of epandrium and thickness of hairs of epandrium and proctiger), in length of hairs of the rear margin of tergite 6, length of the hairs below basal half of hind femur and length of costal cilia (Disney, 2000). The subsequently described M. putescavi Disney runs to this couplet, but it is distinguised from the new species by having hairs on mesopleuron and a clearly different hypopygium, especially a larger left lobe of hypandrium (Disney & Withers, 2011). Material examined. Holotype ♂ Spain, Girona: Arbucias, Montseny Natural Park, beech forest, UTM 31TDG540279, 1250 m a.s.l., 19/05-02/06/1990. Window trap. J.A. Barrientos leg (UAB). Paratype ♂, same date, locality, habitat and capture method as holotype (CCG-R).

Antennae yellow; thorax and abdomen brown; mesopleuron bare; scutellum with a posterior pair of bristles and an anterior pair of hairs; epandrium without bristles, with only hairs about as strong as those on cerci and proctiger; fifth tarsal segment of middle leg about twice length of fourth segment; knob of haltere yellow; four axillary bristles; one hair present at base of vein Rs; costal index more than 0.44. Description (male). Body yellowish. Head. Frons light brown, about as broad as long, with 58 hairs. Upper supra-antennal bristles clearly longer (1.5 ×) and stronger than lower pair, and they are slightly closer together than pre-ocellars, which are at about the same level on frons than mediolaterals and about as far apart as either is from a mediolateral bristles. Upper supraantennal bristles clearly higher on frons than antials, which are a little lower on frons than anterolaterals, and closer to these than to upper supra-antennal bristles. Gena with three long bristles and four shorter ones. Antennal postpedicel subglobose, yellow and relatively small (diameter 0.10 mm), without SPS vesicles. Palps yellow 0.17 mm long and 0.05 mm maximum width, with eight bristles, the longest bristle being longer than greatest width of palp. Labella enlarged, yellow, without short spinules below, with only a few long hairs. Labrum yellow brown, about as wide as an antennal postpedicel. Thorax. Light brown. Mesopleuron bare. Three notopleural bristles and no cleft in front of these. Scutellum

Legs. Yellow. Front legs with a posterodorsal hairs palisade on tarsal segments 1–4 and metatarsus not enlarged. Length ratios of fore tarsal segments 4.3:2:1.7:1.4:1, with fifth segment wider than fourth one. Mid legs with a dorsal hair palisade on tibia extends about 3/4 of its length; fifth mid tarsal segment twice longer than fourth one and wider than the rest tarsal segments. Longest hairs below basal half of hind femur clearly longer (1.8 ×) than those of anteroventral row of outer third. Hind tibia with 17 differentiated posterodorsal hairs and spinules of apical combs simple; fifth hind tarsal segment longer (1.5 ×) and a little wider than fourth one. Wing. Length 2.52 mm. Membrane lightly tinged grey and veins light brown; with four axillary bristles. Subcosta (Sc) well developed, reaching R1. One hair present at base of vein Rs, 0.025 mm long. Costal index 0.47; costal ratios 3.2:2.3:1. Costal cilia (section 3) 0,16 mm long, about as long as longest axillary bristle. Knob of haltere yellow. Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 12 by having the tarsal segment 5 of mid leg twice longer than segment 4, but its hypopygium and colour of thorax and tergites inmediately distinguishes it from the two species of this couplet, M. lutea (Meigen) and M. scutellaris (Wood). The Chinese species M. tibisetalis Fang, runs to the same point, but it differs from the new species by having hairs on mesopleuron, knob of haltere brown, two axillary bristles and no hair at base of vein Rs (Fang et al, 2009). Material examined. Holotype ♂ Spain, Barcelona: Montseny, Montseny Natural Park, beech forest, UTM 31TDG530274, 1130 m a.s.l., 20/10–05/11/1990. Window trap. J.A. Barrientos leg (UAB).

Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 283, to M. maura (Wood). It’s distinguished from the new species by having the fore metatarsus longer and narrower, and by the hypopygium, which has an epandrium with a different shape and with some stronger hairs. M. wickerensis Disney, which run to couplet 285 in the British key, has a very similar hypopygium to the new species, but it differs from the new species, by having the hairs on epandrium about as strong as those on cerci, as well as in the costal index, costal ratios and relative length of costal cilia and axillary bristles (Disney & Perry, 2000). Material examined. Holotype ♂ Spain, Girona: Arbucias, Montseny Natural Park, beech forest, UTM 31TDG540279, 1250 m a.s.l., 19/05-02/06/1990. Window trap. J.A. Barrientos leg (UAB).

Subcosta (Sc) well developed, reaching R1. With 1–2 hairs at base of vein Rs, 0.030–0.045 mm long. Costal index 0.51–0.55; costal ratios 2.7–3.3:1.4–2.2:1. Costal cilia (section 3) 0.10–0.13 mm long, shorter than longest axillary bristle (0.12–0.17 mm). Knob of haltere yellow, brownish at tip. Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 68, where neither option applies, although M. nigriceps (Loew) is close to new species, both with inflated palps with short bristles but they differ in the shape; they also differ in the hypopygium (especially in the shape of epandrium and length of anal tube) and by having, the new species, the hairs below basal half of femur shorter than M. nigriceps (Loew). The subsequently added M. funesta Schmitz runs to the same point; it differs from the new species in the hypopygium (shape of epandrium and length of anal tube), and in the shape of inflated palps (wider in the new species). The related species M. simulans (Wood) has a similar hypopygium to the new species, but the palps of M. simulans (Wood) are smaller and with longer bristles (Disney, 2011b). The species M. specularis Schmitz, with a similar hypopygium to the new species, it differs in shape of epandrium and palps (Disney & Durska, 2011). In the keys of Palaearctic Phoridae (Schmitz et al, 1938–81) this species runs to couplet 22 (Abteilung I, page 407), to M. projecta (Becker), synonym of M. nigriceps (Loew). Material examined.

Abstract One new species of Triphleba Rondani and eight new species of Megaselia Rondani are described from Montseny Natural Park (mainland Spain). The new species are Megaselia arbuciensis García-Romera sp.nov., Megaselia barrientosi García-Romera sp. nov., Megaselia callunae García-Romera sp. nov., Megaselia carminis García-Romera sp. nov., Megaselia ivanis García-Romera sp. nov., Megaselia longianalis García-Romera sp. nov., Megaselia montseniensis GarcíaRomera sp. nov., Megaselia sarae García-Romera sp. nov., Triphleba beatricis García-Romera sp. nov. Key words: Diptera, Phoridae, Triphleba, Megaselia, new species, Montseny, Spain
Introduction The scuttle flies (Diptera: Phoridae) of Spain are still poorly known when compared to other European countries such as United Kingdom or Germany, where more than 300 species have been reported. The most recent catalogue of the Diptera of Spain, which includes both mainland Spain and the Canary and Balearic Isles, lists 214 species (García Romera & Baez, 2002). Subsequent additions have cited 22 new records and new species (Disney & Prescher, 2003; Disney & Blasco-Zumeta, 2004; Carles-Tolrà, 2006a,b,c, 2011a,b; Disney, 2006a,b,c, 2009, 2011a, 2012; Disney & Pagola-Carte, 2009; Disney & Franquinho Aguiar, 2010; Disney et al., 2010; Carles-Tolra & García Romera, 2011). The genus Triphleba Rondani includes about 90 species around the world, except the Afrotropical Region (Disney, 1994). 56 species are known in Europe (Disney, 1991; Weber & Prescher, 2013; Carles-Tolrá & García Romera, 2011) and 12 species were listed in the most recent catalogue of Spain (García Romera & Baez, 2002). Subsequent studies have recorded 3 species (Carles-Tolrá, 2006c, 2011b) and have described a new species for this genus (Carles-Tolrá & García Romera, 2011). The giant genus Megaselia Rondani includes around 1500 species, about the half of the known Phoridae. More than 400 species are recorded from Europe (Disney, 1999, 2008) and 155 species have been reported in Spain (García Romera & Baez, 2002) (128 mainland Spain and 55 Canary and Balearic Islands); subsequent additions, including new species and new records, have increased the number in 10 species (Disney 2009, 2011a, 2012; Disney & Pagola-Carte, 2009; Disney et al., 2010). In this paper, nine new species are described, belonging to the genera Triphleba Rondani and Megaselia Rondani.
Material and methods The material were collected by José Antonio Barrientos in Montseny Natural Park (Catalonia, North East Spain), an UNESCO biosphere reserve, between March 1990 and March 1991 using window, water and pitfall traps. Traps were placed in three plots located in a beech (Fagus sylvatica L.) forest. Two plots were located in Montseny (Barcelona), at 1130 m a.s.l. (UTM 31TDG530274) and at 1170 m a.s.l. (UTM 31TDG532273), respectively, while

the third plot was located in Arbúcies (Girona), at 1250 m a.s.l. (UTM31TDG540279). Two additional plots were layed in a Calluna vulgaris (L.) scrubland at 1520 m a.s.l (UTM 31TDG542245) and in a Juniperus communis L. scrubland at 1620 m a.s.l (UTM 31TDG530256 ). The material were preserved in ethanol (70%) and most specimens were subsequently fully dissected and standard slide-mounted in Berlese fluid (see Disney, 1983, 1994). Drawings were made using a Leica Leitz DMRB microscope with drawing attachment. Most specimens are deposited in the Universidad Autónoma de Barcelona (UAB) and some in the private collection of first author (CCG-R).

Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 87, after return of 182, to M. conformis (Wood), but its hypopygium clearly differs from the new species, in the shape of epandrium and development of posterior lobe of hypandrium; the subsequently added M. lactipennis Lundbeck, runs to the same point; it differs from the new species clearly in the hypopygium (development of posterior lobes of hypandrium, shape of epandrium and thickness of hairs of epandrium and proctiger), in length of hairs of the rear margin of tergite 6, length of the hairs below basal half of hind femur and length of costal cilia (Disney, 2000). The subsequently described M. putescavi Disney runs to this couplet, but it is distinguised from the new species by having hairs on mesopleuron and a clearly different hypopygium, especially a larger left lobe of hypandrium (Disney & Withers, 2011). Material examined. Holotype ♂ Spain, Girona: Arbucias, Montseny Natural Park, beech forest, UTM 31TDG540279, 1250 m a.s.l., 19/05-02/06/1990. Window trap. J.A. Barrientos leg (UAB). Paratype ♂, same date, locality, habitat and capture method as holotype (CCG-R).

Antennae yellow; thorax and abdomen brown; mesopleuron bare; scutellum with a posterior pair of bristles and an anterior pair of hairs; epandrium without bristles, with only hairs about as strong as those on cerci and proctiger; fifth tarsal segment of middle leg about twice length of fourth segment; knob of haltere yellow; four axillary bristles; one hair present at base of vein Rs; costal index more than 0.44. Description (male). Body yellowish. Head. Frons light brown, about as broad as long, with 58 hairs. Upper supra-antennal bristles clearly longer (1.5 ×) and stronger than lower pair, and they are slightly closer together than pre-ocellars, which are at about the same level on frons than mediolaterals and about as far apart as either is from a mediolateral bristles. Upper supraantennal bristles clearly higher on frons than antials, which are a little lower on frons than anterolaterals, and closer to these than to upper supra-antennal bristles. Gena with three long bristles and four shorter ones. Antennal postpedicel subglobose, yellow and relatively small (diameter 0.10 mm), without SPS vesicles. Palps yellow 0.17 mm long and 0.05 mm maximum width, with eight bristles, the longest bristle being longer than greatest width of palp. Labella enlarged, yellow, without short spinules below, with only a few long hairs. Labrum yellow brown, about as wide as an antennal postpedicel. Thorax. Light brown. Mesopleuron bare.

Legs. Yellow. Front legs with a posterodorsal hairs palisade on tarsal segments 1–4 and metatarsus not enlarged. Length ratios of fore tarsal segments 4.3:2:1.7:1.4:1, with fifth segment wider than fourth one. Mid legs with a dorsal hair palisade on tibia extends about 3/4 of its length; fifth mid tarsal segment twice longer than fourth one and wider than the rest tarsal segments. Longest hairs below basal half of hind femur clearly longer (1.8 ×) than those of anteroventral row of outer third. Hind tibia with 17 differentiated posterodorsal hairs and spinules of apical combs simple; fifth hind tarsal segment longer (1.5 ×) and a little wider than fourth one. Wing. Length 2.52 mm. Membrane lightly tinged grey and veins light brown; with four axillary bristles. Subcosta (Sc) well developed, reaching R1. One hair present at base of vein Rs, 0.025 mm long. Costal index 0.47; costal ratios 3.2:2.3:1. Costal cilia (section 3) 0,16 mm long, about as long as longest axillary bristle. Knob of haltere yellow. Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 12 by having the tarsal segment 5 of mid leg twice longer than segment 4, but its hypopygium and colour of thorax and tergites inmediately distinguishes it from the two species of this couplet, M. lutea (Meigen) and M. scutellaris (Wood). The Chinese species M. tibisetalis Fang, runs to the same point, but it differs from the new species by having hairs on mesopleuron, knob of haltere brown, two axillary bristles and no hair at base of vein Rs (Fang et al, 2009). Material examined. Holotype ♂ Spain, Barcelona: Montseny, Montseny Natural Park, beech forest, UTM 31TDG530274, 1130 m a.s.l., 20/10–05/11/1990. Window trap. J.A. Barrientos leg (UAB).

Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 283, to M. maura (Wood). It’s distinguished from the new species by having the fore metatarsus longer and narrower, and by the hypopygium, which has an epandrium with a different shape and with some stronger hairs. M. wickerensis Disney, which run to couplet 285 in the British key, has a very similar hypopygium to the new species, but it differs from the new species, by having the hairs on epandrium about as strong as those on cerci, as well as in the costal index, costal ratios and relative length of costal cilia and axillary bristles (Disney & Perry, 2000). Material examined. Holotype ♂ Spain, Girona: Arbucias, Montseny Natural Park, beech forest, UTM 31TDG540279, 1250 m a.s.l., 19/05-02/06/1990. Window trap. J.A. Barrientos leg (UAB).

Costal cilia (section 3) 0.10–0.13 mm long, shorter than longest axillary bristle (0.12–0.17 mm). Knob of haltere yellow, brownish at tip. Recognition. In the keys to the males of the British species of Megaselia (Disney, 1989) this species runs to couplet 68, where neither option applies, although M. nigriceps (Loew) is close to new species, both with inflated palps with short bristles but they differ in the shape; they also differ in the hypopygium (especially in the shape of epandrium and length of anal tube) and by having, the new species, the hairs below basal half of femur shorter than M. nigriceps (Loew). The subsequently added M. funesta Schmitz runs to the same point; it differs from the new species in the hypopygium (shape of epandrium and length of anal tube), and in the shape of inflated palps (wider in the new species). The related species M. simulans (Wood) has a similar hypopygium to the new species, but the palps of M. simulans (Wood) are smaller and with longer bristles (Disney, 2011b). The species M. specularis Schmitz, with a similar hypopygium to the new species, it differs in shape of epandrium and palps (Disney & Durska, 2011). In the keys of Palaearctic Phoridae (Schmitz et al, 1938–81) this species runs to couplet 22 (Abteilung I, page 407), to M. projecta (Becker), synonym of M. nigriceps (Loew). Material examined.

Holotype ♂ Spain, Girona: Arbucias, Montseny Natural Park, beech forest, UTM 31TDG540279, 1250 m a.s.l., 27/12/1990-20/01/1991. Window trap. J.A. Barrientos leg (UAB). Paratypes 3 ♂, one same date, locality and habitat as holotype and two others Barcelona: Montseny, Montseny Natural Park, beech forest, UTM 31TDG530274, 1130 m a.s.l., 05–17/11/1990. Window trap. J.A. Barrientos leg (UAB and CCG-R). Note. Another species of Megaselia was going to describe in this paper when R.H.L. Disney comunicated us which this species is currently described in a paper based on specimens from Italy (Disney, Weber & Prescher, in press). The data of captured specimens in our survey is cited below. Material examined: Spain, Barcelona: Montseny, Montseny Natural Park. 2 ♂ Juniperus scrubland, UTM 31TDG530256, 1620 m a.s.l., 27/06–07/07/1990, one window trap and one water trap; 1 ♂ Calluna scrubland, UTM 31TDG542245, 1520 m a.s.l., 27/06/1990, water trap; 2 ♂ beech forest, UTM 31TDG530274, 1130 m a.s.l., one water trap (17/06/1990) and one window trap (01–14/07/1990); 4 ♂ beech forest, UTM 31TDG532273, 1170 m a.s.l, window trap, one 02–16/06/1990 and three 16/06–01/07/1990.
