( Figs. 148–151 View FIGURES 148–151 , 193 View FIGURES 160–195 , 231 View FIGURES 196–233 , 322–323 View FIGURES 320–323 )

Diagnosis (males). Epandrial medial process large, apically sclerotized, curved, with dorsal and ventral sharp edges; hypandrium left lobe with a sclerotized triangular lateral projection near apex; epiphallus not evident, a transparent membrane in its original position; ventral plate with long, setulose, sclerotized spine.

Material examined. Holotype ♂, COSTA RICA: Puntarenas: Cerro Rincon , 8.52ºN, 83.47ºW, i.1991, Malaise trap, 745 m, P. Hanson col. ( LACM) GoogleMaps . Paratype: 1♂, same data as holotype GoogleMaps .

Description. Male. Body length, 3.6 mm. Head. Frons dark brown, with anterior apex yellow, pubescent, apparently with vestigial median furrow near ventral apex. Flagellomere 1 light brown, pubescent, oval. Arista preapical, pubescent. Palpus light brown; two upper genal and one lower genal setae. Thorax. Scutum yellowishbrown, brown posteriorly, pleural sclerites yellowish-brown; anepisternum setulose dorsally, with one long seta; scutellum dark brown, with medial and posterior areas yellowish-brown. Legs yellowish-brown, hind femur brown near apex. Forefemur with ventral row of four strong setae near apex. Foretibia with one dorsal seta at basal third and an anterodorsal row of strong setae. Foremetatarsus ratio, 4.4. Midtibia with one anterodorsal and one posterodorsal seta at basal fourth ( Fig. 193 View FIGURES 160–195 ). Hind femur swollen (height/length ratio, 0.41), without ventral, strong setae. Hind tibia with 2–3 anterodorsal and five posterodorsal setae ( Fig. 231 View FIGURES 196–233 ). Wing. Costa 0.49 of the wing length, other wing features as for the genus. Halter yellowish-brown. Abdomen. Tergites dark brown, with yellow anterior and posterior bands. Hypopygium yellowish-brown ( Figs. 148–151 View FIGURES 148–151 ). Epandrial medial process large, curved, not bifurcated, apically sclerotized, with dorsal and ventral sharp edges. Epandrial right posterior margin without projections, with subepandrial setulose process. Hypandrium lobes about of same size, left lobe with sclerotized triangular lateral projection near apex. Hypoproct with two setae. Phallus ( Figs. 322–323 View FIGURES 320–323 ). Basiphallus with slightly developed dorsal process. Core plate flattened, bilobed. Epiphallus not evident, a transparent membrane in its original position. Ventral plate mostly not evident, except for a long setulose sclerotized spine.

Female. Unknown.

Geographic distribution. Known only from the type-locality, a mid-altitude site in Costa Rica.

Etymology. The specific epithet hymenodrilus is derived from the Greek roots hymen (membrane) and drilos (penis), and refers to the transparent membrane of the phallus. It should be treated as a noun in apposition.

Comments. Neopleurophora hymenodrilus can be considered one of the most distinctive species of Neopleurophora , especially in respect to phallic morphology, with an apparently absent epiphallus and a membrane occupying its area.
