Neohybos fuliginosus View in CoL sp. nov.

( Figs. 7–11 View Figs , 44 View Figs )

Diagnosis. Thorax black, entirely pruinose, pruinescence mostly pale brown, scutum with mixed pale and green pruinescence laterally and wide dorsal golden brown stripe.Scutum almost bare, setae inconspicuous; posterior dc pair not developed. Postpedicel slender and lanceolate. Legs brown to black with mid tibia and all tarsomeres 1–2 yellow, hind tibia yellow with ventral surface brown. Wing hyaline, stigma pale. Abdomen long and slender, 3.3 times longer than length of thorax. Distal margin of hypandrium bilobed, left lobe small and right lobe very long, slender and sinuous, at least 9 times length of right lobe.

Description. Holotype male (UTPL) ( Fig. 44 View Figs ). Body: 5.2 mm. Wing: 5.2 mm. Head. Postpedicel 3 times longer than wide, longer than length of scape and pedicel combined. Face narrowly dichoptic, as long as frons. One pair of elongate divergent ocellar setae. Postcranium clothed in dense pale-yellow pruinescence; postocular setae somewhat elongate; occipital setae thin, yellow and uniserial.Thorax black, entirely pruinose, pruinescence mostly pale brown, scutum with mixed pale and green pruinescence laterally and wide dorsal golden brown stripe. Acrostichal and dc uniserial, short, very thin and sparse, brown, posterior dc pair not developed; ial and spal setae sparse; 2 elongate npl setae, shorter than apical scutellar pair; pal seta as long as npl. Scutellum with 4 pairs of setae: apical pair long, robust, parallel, widely separated, twice longer than lateral seta, which is very thin. Legs brown to black with mid tibia and all tarsomeres 1–2 yellow, hind tibia yellow with ventral surface brown. Hind femur slightly thickened; hind tibia slightly arched, cylindrical. Setae mostly yellow. Fore tibia with 1A short seta, and 1P preapical seta, poorly differentiated. Fore tarsomere 1 with 1A short seta and 1P preapical seta. Mid tibia bearing 2 AD elongate and strong setae on dorsal half and 1P long apical seta, almost reaching apex of tarsomere 1. Mid tarsomere 1 with 1AD short and robust seta, 1PD preapical seta, and 1 V long sub-basal seta extending beyond mid-length of tarsomere 1. Hind trochanter with several robust setae. Hind femur with 3D setae on distal fourth; 1A seta near apex; 9AV spine-like elongate setae; 14 V spine-like setae with protuberant bases, 6 basalmost setae well developed and 8 apicalmost setae reduced to short robust spines; PV series with 3 long setae on apical half. All tarsomeres 1 with 1D basal seta and 1D preapical seta, both somewhat elongate. Hind tibia lacking outstanding setae. Wing narrow; hyaline with pale stigma; costal cell narrow; R 4+5 and M 1 slightly convergent apically. Abdomen brown, darkening toward base; long and slender, about 3.3 times longer than length of thorax; all segments covered by very fine, sparse, pale-brown pruinescence. Setulae yellow, very thin, short and inconspicuous dorsally; long setae on tergite 1, laterally on tergites 2–3 and on distal margin of sternite 8. Terminalia ( Figs. 7–11 View Figs ). Distal margin of hypandrium bilobed, left lobe small and right lobe very long, slender and sinuous, at least 9 times length of right lobe. Right epandrial lamella deeply cleft distally; left surstylus rounded and bearing robust spine-like setae inserted on tubercles. Postgonite slender, left postgonite long and connected to left hypandrial arm. Phallus long and slender.

Etymology. From the Latin fuligo = soot, in reference to the dense pruinescence covering the thorax.

Female. Unknown.

Type material. Holotype male (UTPL). ECUADOR. Loja: Cajanuma, Podocarpus National Park, trail Los Miradores , 3000 m, 16/02/2009 – 20/02/2009 (YPT), leg. Marc Pollet & Anja De Braekeleer , EC /2009-31/MP&ADB-003. Condition: good, abdomen dissected.

Geographical distribution. Ecuador (Loja).

Etymology. From the Latin fuligo = soot, in reference to the dense pruinescence covering the thorax.

Comments. This species resembles Neohybos schlingeri Ale-Rocha, 2007 from Colombia in the colored stigma, wing hyaline, scutum wholly pruinose, lack of a strong pair of dc setae and hypandrium with very long and slender, sinuous distal lobe. However, in N. fuliginosus sp. nov., the long distal lobe of the hypandrium is positioned laterally, the tibiae are yellow, the right bacilliform sclerite lacks a process and the epandrium has a different shape that can easily distinguish it from N. schlingeri .
