Diagnosis (males). Epandrium base at the left with a ventral, setulose ridge; phallic ventral plate well developed, reaching left margin laterally, with a large, proximal lobe.

Material examined. Holotype ♂, BOLÍVIA: La Paz: 40 km Caranavi: Cumbre Alto Beni, 15.83ºS, 67.56ºW, 7–15.iv.2004, Malaise trap, 1,600 m, S. Gaimari & M. Hauser col. ( CBFC). GoogleMaps  

Description. Male. Body length, 3.2 mm. Head. Frons dark brown, pubescent, without median furrow. Flagellomere 1 light brown, pubescent, oval. Arista pre-apical, pubescent. Palpus yellowish-brown; 1–2 lower genal setae. Thorax. Scutum and pleural sclerites dark brown; anepisternum setulose dorsally, with one long seta; scutellum dark brown, with medial and posterior areas reddish-brown. Legs light brown, except foretarsus, yellowish-brown. All femora with ventral row of long setae along its entire extension. Foretibia with one dorsal seta at basal third and an anterodorsal row of strong setae. Foremetatarsus ratio, 4.5. Midtibia with one anterodorsal and four posterodorsal setae ( Fig. 171 View FIGURES 160–195 ). Hind femur swollen (height/length ratio, 0.43). Hind tibia with three anterodorsal and 5–6 posterodorsal setae ( Fig. 208 View FIGURES 196–233 ). Wing. Costa 0.46 of the wing length, other wing features as for the genus. Halter white. Abdomen. Tergites dark brown, with lighter posterior band and dense microtrichia producing a silvery sheen. Hypopygium brown ( Figs. 56–59 View FIGURES 56–59 ). Epandrial medial process not bifurcated, approximately square. Epandrial right posterior margin ventral apex slightly projected posteriorly, without subepandrial process. Epandrium left lateral base with ventral, setulose ridge. Hypandrium lobes with almost the same size; right lobe serrated at apex. Hypoproct with seven setae. Phallus ( Figs. 276–277 View FIGURES 276–279 ). Basiphallus without dorsal process. Core plate membranous, with left, triangular projection. Epiphallus ending free, with thin, transparent scales. Ventral plate well developed, reaching the left side of the phallus, with large, proximal lobe at the left lateral.

Female. Unknown.

Geographic distribution. Known only from the type-locality in Bolivia.

Etymology. The specific epithet refers to the type-locality, in Bolivia, and should be treated as a noun in apposition.

Comments. Neopleurophora boliviana   and N. atlantica   have very distinctive hypopygial and phallic morphology. The large hypandrial right lobe and the three anterodorsal setae on the hind tibia, however, are features shared between both species that seem to indicate their close relationship.

II. Species with epiphallus connected to the right arm at the left lateral of the phallus

Diagnosis. Epiphallus connected to the right arm laterally at the left of the phallus ( Figs. 278–327 View FIGURES 276–279 View FIGURES 280–283 View FIGURES 284–287 View FIGURES 288–291 View FIGURES 292–295 View FIGURES 296–299 View FIGURES 300–303 View FIGURES 304–307 View FIGURES 308–311 View FIGURES 312–315 View FIGURES 316–319 View FIGURES 320–323 View FIGURES 324–327 ). Right subepandrial setulose process present ( Fig. 63 View FIGURES 60–63 ). Phallic ventral plate well developed ( Figs. 278–279 View FIGURES 276–279 ). Midtibia generally with one anterodorsal seta (except for Neopleurophora polychaetopoda   , N. browni   , N. setiventris   and N. setipes   ).
