Neopleurophora setipes ( Borgmeier, 1961)

( Figs. 88–91 , 179 , 216 , 248–249 , 292–293 )

Chaetopleurophora setipes Borgmeier, 1961: 9 .

Neopleurophora setipes ; Brown, 1992: 51.

Diagnosis (males). Epandrial medial process bifurcated; ventral plate of the phallus with three apical folds composing a circular opening. Hind tibia with three anterodorsal and 4–5 posterodorsal setae.

Material examined. Holotype ♂, COSTA RICA: Higuito : San Mateo, xii.1966, Pablo Schild col ( MCZC) ; Paratype, 1 ♂, same data as holotype, but ( MZUSP) . Additional material: 1 ♂, Puntarenas 5 km W Piedras Blancas , 8.77ºN, 83.28ºW, vi–viii.1989, Malaise trap, 100 m, P. Hanson col. ( LACM) ; 2 ♂, Puntarenas 3 km Rd. to Rincon 24 km W PanAmerican Hwy, iii–iv.1989, Malaise trap, P. Hanson & I. Gauld col. ( LACM) .

Redescription. Male. Body length, 2.7 mm. Head. Frons dark brown, with anterior edge yellow, pubescent, without median furrow. Flagellomere 1 reddish-brown, pubescent, oval. Arista pre-apical, pubescent. Palpus light brown; one lower genal and two upper genal small seta. Thorax. Scutum dark brown, pleural sclerites brown; anepisternum setulose dorsally, with one long seta; scutellum dark brown, with posterior margin gray. Legs light brown. Forefemur with ventral row of four strong setae near apex. Foretibia with one dorsal seta at basal fourth and an anterodorsal row of strong setae. Foremetatarsus ratio, 5. Midtibia with 1–2 anterodorsal and three posterodorsal setae ( Fig. 179 ). Hind femur swollen (height/length ratio, 0.41), with ventral row of 2–4 strong setae and many thinner proximal setae near base ( Figs. 248–249 ). Hind tibia with three anterodorsal and 4–5 posterodorsal setae ( Fig. 216 ). Wing. Costa 0.47 of the wing length, other wing features as for the genus. Halter white. Abdomen. Tergites dark brown, with posterior yellow band. Hypopygium light brown ( Figs. 88–91 ). Epandrial medial process bifurcated. Epandrial right posterior margin with posterior projection; subepandrial setulose process present. Hypandrium lobes well developed, left lobe larger. Hypoproct with two setae. Phallus ( Figs. 292–293 ). Basiphallus without dorsal process. Core plate flattened, bilobed. Epiphallus with medium size scales, connected to the right arm at left lateral of the phallus. Ventral plate well developed, with three folds near apex forming a circular opening.

Female. Unknown.

Geographic distribution. This species is known from two low altitude sites in west Costa Rica.

Comments. This redescription of N. setipes , besides describing for the first time the hypopygium and the phallus of this species, complements the original description ( Borgmeier, 1961) mainly by recognizing the presence of hind femur strong setae.
