Neopleurophora synaptodrilus , sp. nov.

( Figs. 12–15 , 161 , 197 , 254–255 )

Diagnosis (males). Epandrial medial process approximately rectangular, with a sharp projection near base; hypandrium lobes sclerotized, elongated.

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

Description. Male. Body length, 2.9 mm. Head. Frons dark brown, pubescent, without median furrow. Flagellomere 1 light brown, pubescent, oval. Arista pre-apical, pubescent. Palpus yellowish-brown; one upper genal and one lower genal seta. Thorax. Scutum dark brown, pleural sclerites brown; anepisternum setulose, with one long seta; scutellum dark brown, with medial and posterior areas gray. Foreleg yellowish-brown, mid and hind legs light brown. Forefemur with ventral row of strong setae along its entire extension. Foretibia with one dorsal seta at basal third and an anterodorsal row of strong setae. Foremetatarsus ratio, 4. Midtibia with one anterodorsal and four posterodorsal setae ( Fig. 161 ). Hind femur not swollen (height/length ratio, 0.39), without strong setae. Hind tibia with three anterodorsal and six posterodorsal setae ( Fig. 197 ). 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 light brown ( Figs. 12–15 ). Epandrial medial process approximately rectangular, with two pointed apical edges and acute projection near base. Epandrial right posterior margin rounded, without subepandrial setulose process. Hypandrium lobes sclerotized, elongated, of approximately same size. Hypoproct with seven setae. Phallus ( Figs. 254–255 ). Basiphallus without dorsal process. Core plate membranous. Right arm fused to the basiphallus and to the ventral plate, constituting a short ventral process. Epiphallus occupying phallus left side, ending free, covered with thin, transparent scales.

Female. Unknown.

Geographic distribution. Known only from the type-locality in La Paz, west Bolivia.

Etymology. The specific epithet synaptodrilus refers to the fusion of the basiphallus and the phallic right arm and is derived from the Greek roots synaptos (joined together) and drilos (penis). It should be treated as a noun in apposition.
