( Figs. 73–75 View FIGURES 71–78 , 210 View FIGURES 204–212 )

Description. Head reddish brown to dark brown, occiput and face black, first flagellomere light brown, maxillary palp yellow. Occiput and gena covered with microtomentum, frons mostly shiny with microtomentum on orbital plates and medially from postocellar bristles through ocellar triangle to bases of ocellar bristles, face entirely shiny. Posterior orbital and outer vertical bristles absent. Ocellar bristles at level of median ocellus. Anterior genal and subvibrissal bristles not developed. Gena about 0.4X eye height. Labellum with 26 pseudotrachea.

Thorax black. Mostly covered with microtomentum, proepisternum shiny, anepisternum with microtomentum above level of spiracle and on posterior quarter, katepisternum with shiny spot behind fore coxa and with posterior portion above mid coxa shiny, meron with microtomentum along anterior margin, metapleuron shiny. Lateral postalar, apical scutellar, and katepisternal bristles long, postpronotal, notopleural, and basal scutellar bristles short, other bristles absent or indistinguishable from surrounding setae. Thorax slightly narrower than head, about twothirds width of abdomen, scutellum very short, wing and halter absent.

Legs black, trochanters and tarsi brown. Mid tibia without preapical bristles, 5 apical bristles. Hind tibia with 2 ventroapical bristles.

Abdomen strongly convex. Tergites and sternites heavily sclerotized, black, covered with microtomentum.

Male postabdomen: Sternite 5 with lateral margins slightly rounded, shallowly emarginated posteriorly, anterior apodeme long, reaching segment 2, without keel ( Fig. 75 View FIGURES 71–78 ). Surstylus curved, narrow apically ( Fig. 74 View FIGURES 71–78 ). Pregonite small, distinct. Postgonite with lobes clearly separated, nearly equal width, posterior lobe long, pointed, anterior lobe rounded. Basiphallus broad, without epiphallus, preepiphallus short, transparent. Distiphallus simple, with a stout spinose dorsal tube, ventral sclerites heavily sclerotized ( Fig. 73 View FIGURES 71–78 ).

Female postabdomen: Tergites 6–7 weakly sclerotized medially, tergite 6 with anterior margin heavily sclerotized, tergite 7 with anterior and lateral margins heavily sclerotized. Sternite 6 weakly sclerotized medially, with anterior margin, and 2 posterior spots heavily sclerotized, sternite 7 heavily sclerotized, narrow posteriorly, covered with microtomentum. Tergites with 3 posterior weakly sclerotized strips, sternites with 2 posterior strips. Tergite 8 broad, shallowly emarginated anteriorly and posteriorly, with microtomentum except along anterior margin. Epiproct with long parallel anterior arms, covered with microtomentum posteriorly, with 1 pair of setae. Sclerites of tergite 8 broad, pinched medially, posterior third with microtomentum and setae. Hypoproct round, with a square anterior notch, shiny lateral to notch. Spermathecae round, without invaginations, sclerotized ducts about as long as spermathecae.

Type material. Holotype ♂: VENEZUELA: Trujillo: Guaramacal Natl. Pk., 19.3 km SE Boconó , 9°14'11"N 70°11'07"W, 2800 m, páramo, shrub litter, 19 May 1998, R. Anderson, debu00103182 ( MIZA) GoogleMaps . Paratypes: same data as holotype (3 ♂, 2 ♀, DEBU); Boconó , Páramo de Guaramacal, 2800 m, 8–28 Jul 1986, B. Gill (1 ♂, 1 ♀, DEBU) GoogleMaps .
