Ale-Rocha, R., 2007, New species of Neohybos Ale-Rocha & Carvalho (Diptera, Hybotidae, Hybotinae) from Colombia, Ecuador and Peru, Zootaxa 1503, pp. 33-54 : 50

Neohybos schlingeri sp. n.

( Figs. 61 – 65 )

Diagnosis. Thorax dark-brown to black with red-brown pruinescence except small area on postpronotal lobe; thoracic setae short, black, sparse; wing slightly brownish, stigma brown; legs dark-brown except mid and hind tibiae pale-brown and tarsomeres 1 and 2 pale-brown to yellow; abdomen and legs clothed in yellow and brown bristles, respectively..

Description. Holotype male. Body: 4.0 mm. Wing: 3.9 mm. Antenna placed at middle of head; postpedicel oval, 2.5 times longer than wide, as long as scape and pedicel combined. Face narrowly dichoptic, as long as frons. Pair of ocellar setae slender, parallel. Postcranium with brownish pruinescence; occipital setae sparse, elongate, disordered.

Thorax dark-brown to black entirely red-brown pruinose except small area on postpronotal lobe; thoracic setae short, black, sparse; acr and dc uniserial; 2 npl long and strong, as long as apical scutellar pair; scutellum with 1 apical pair long, robust, broadly separate, slightly divergent, 2 thin lateral pairs short and weak, about one-fifth length of apical pair.

Wing narrow; slightly brownish, stigma brown; R4+5 and M1 parallel.

Legs dark-brown except mid and hind tibiae pale-brown and tarsomeres 1 and 2 pale-brown to yellow. Bristles brown. Hind femur discreetly thickened, 5 times longer than wide; hind tibia tubular. Outstanding bristles: fore tibia with 1 short anterior preapical bristle and 1 long posterior preapical bristle reaching half of corresponding tarsomere 1; mid tibia with 5 elongate anterodorsal bristles and 1 long ventral apical bristle reaching apex of corresponding tarsomere 1; first mid tarsomere with 1 long posteroventral sub-basal bristle reaching base of tarsomere 2 and 1 long dorsal preapical bristle; hind trochanter with 1 ventral spine; hind femur with 2 dorsal and 1 anterior bristles on distal quarter, 9 anteroventral spine-like bristles rather disordered, ventral surface with 10 thorns on distal half and 3 spine-like bristles on basal half; 6 elongate posteroventral thorns on distal half and 1 short thorn sub-basal; hind tibia without stout bristles.

Abdomen 2.8 times longer than thoracic length; dark-brown, shiny, with sparse brown pruinescence on Tg1 and Tg8 and sternites; bristles yellow, scattered and thin, long on Tg1 – Tg3; St8 with long yellow bristles on distal margin. Terminalia ( Figs. 61–65 ): left and right epandrial lamellae with three and two long distal processes, respectively; right bacilliform sclerite with broad, rounded process bearing short tubercles on margin; hypandrium with three lobes, lateral lobes short and median lobe very long, slender, sinuous, with hooklike tip; dorsal bridge complete; postgonites slender, ribbon-like.

Female. Unknown.

Distribution. Colombia.

Type material. Holotype male: COLOMBIA: 14 mi. W. Fresno Tolina, 2330 m, iii.16. 1955, E. I. Schlinger & E. S. Ross coll. ( CAS).

Etymology. The specific name is homage to one of the collectors of the holotype, E. I. Schlinger.
