Neohybos globosus View in CoL sp. nov.

( Figs. 12–15 View Figs , 45 View Figs , 52 View Figs )

Diagnosis. Thorax black, scutum shiny with brown pruinescence only laterally and prescutellar disc. Postpedicel slender and fusiform. Legs black except for yellow apex of all femora, fore tibia pale brown with base and apex yellow, mid tibia and all tarsomeres 1–2 pale yellow, hind tibia yellow on basal half, remaining dark brown, all tarsomeres 3–5 brown. Wing slightly brownish, stigma pale. Hypandrium short and wide, distal margin truncate, bearing several long thin setae.

Description. Holotype male (QCAZ) ( Fig. 45 View Figs ). Body: 4.8 mm. Wing: 4.5 mm. Head. Postpedicel small, twice longer than wide, shorter than length of scape and pedicel combined. Face narrowly dichoptic, black, shorter than frons. Postcranium clothed in sparse brown pruinescence; postocular setae elongate; occipital setae short and somewhat numerous. Thorax black; scutum shiny with brown pruinescence laterally and on prescutellar disc. Pleura covered by dense brown pruinescence. Setae black; acr and dc setae uniserial, thin, short and very sparse; ial and spal setae elongate; 2 npl setae as long as apical scutellar pair; pal seta developed but shorter than npl seta; posterior dc pair not elongate. Scutellum with 5 pairs of setae: one apical pair long, robust, divergent, widely separated; 3 lateral pairs slender, half-length of apical pair; one pair of very thin and small crossed setae between apical pair. Legs black except yellow apex of all femora, fore tibia pale brown with base and apex yellow, mid tibia and all tarsomeres 1–2 pale yellow, hind tibia yellow on basal half, dark brown on apical half, all tarsomeres 3–5 brown. Hind femur slightly thickened toward apex, claviform, clothed in sparse thin yellow setulae; hind tibia nearly straight, cylindrical, with brown setulae. Fore tibia with 1A short seta and 1P elongate seta reaching mid-length of tarsomere, and 1 preapical seta. Fore tarsomere 1 with 1A seta and 1P preapical seta, both elongate and robust. Mid tibia with 2AD, short and more robust setae above middle and 1P long apical seta reaching tarsomere 1. Mid tarsomere 1 with 1AD short and robust preapical seta, and 1 V elongate sub-basal seta, reaching apex of tarsomere 1. Hind trochanter with 3 spine-like setae. Hind femur ( Fig. 52 View Figs ) with 2D setae and 1A seta near apex; 8AV elongate spine-like setae; 13 V short spine-like setae with protuberant bases, eight distalmost setae reduced to short robust spines; PV series with 3 setae on basal third and 5 on apical third. Fore and mid tarsomere 1 with 1A short and robust basal seta. Hind tibia without stout setae. Wing narrow, slightly brownish, stigma pale; costal cell narrow; R 4+5 and M 1 slightly convergent apically. Abdomen black; shiny with brown pruinescence on tergite 1, tergite 8, sternites with sparse brown pruinescence; abdomen about 2.7 times longer than thorax. Setulae thin and short, very sparse and almost inconspicuous dorsally, yellow; long setae on tergite 1, lateral on tergites 2–4 and very long and numerous on distal margin of sternite 8 (as long as sternite). Terminalia ( Figs. 12–15 View Figs ). Hypandrium short and wide, distal margin truncate, bearing several long thin setae. Right epandrial lamella bearing long and stout spine-like setae and a long ventral process, both on distal margin; left epandrial lamella with long and robust process on distal margin and a series of long and very slender setae along ventral margin. Postgonite ribbon-like, slender; phallus short, robust, swollen apex bearing short lobes and strong spines.

Female. Unknown.

Type material. Holotype male (QCAZ). ECUADOR. Zamora Chinchipe, Estación Cientifica San Francisco [Reserva Biológica San Francisco], 0713956-9560588, Canal trail 1956 m, Varredura, 12–17/iv/2015, A. Plant & J. Camara Leg. Condition: good except the left postpedicel and stylus, right stylus and ocellar setae lost; not dissected.

Paratypes: same data as holotype (2 males QCAZ; 1 male INPA) .

Geographical distribution. Ecuador (Zamora Chinchipe).

Etymology. From the Latin globus = ball, in reference to the globose appearance of the male hypopygium.

Comments. In the external morphology, this species is similar to N. colombiensis Ale-Rocha, 2007 . With respect to male terminalia, the most conspicuous difference between this species can be seen in the shape of hypandrium which is short and wide with distal margin truncate, bearing several long thin setae in N. globosus sp. nov.
