Nephochaetopteryx equatoriana View in CoL sp. nov.
( Fig. 11 View FIGURE 11 )
Type material. HOLOTYPE ♁ ( MNRJ): Coca , Napo R. / Napo, ECUADOR /. V.1965 / 250m., L. Pena // Nepho- chaetopteryx / near / marianae / Det. H.S. Lopes [printed and handwritten on rectangular white label bordered with black]. [Holotype in good condition, with cleared terminalia preserved in glycerin in a microvial pinned beneath the specimen.]
Description. Male (holotype). Length = 5.2 mm.
Head. Fronto-orbital and parafacial plates, postocular strip, gena and postgena with golden microtomentum. Frontal vitta black, reddish on basal half. Five to six frontal setae. Palpus yellow.
Thorax. Chaetotaxy: dorsocentrals 2+3; intra-alars 2+2; supra-alars 1+3; notopleurals 1, subprimary, anepisternals 5; merals 5. Mid femur with two median setae and without a differentiated posteroventral seta. Ctenidium consisting of four spines. Wing hyaline, with dark spot beginning in the terminal portion of vein R 1, filling the distal third of cell r 1 and the upper half of the distal half of cell r 2+3; vein R 4+5 setulose dorsally to crossvein r-m.
Abdomen. Syntergite 1+2 orange, tergite 3 orange with a narrow median and posterior brown strip, tergite 4 brown with a band of yellowish microtomentum on anterior 4/5 of dorsal and lateral surfaces, tergite 5 dark brown. Sternites 2 to 4 rectangular, sternites 2 to 3 yellow with a median brown spot on posterior margin, sternite 4 with basal half yellow and posterior half brown.
Terminalia. Sternite 5 brown, with a very shallow cleft, not passing the anterior margin of lobe; lobe pointed; posterior arm clubbed, projected posteriorly. Syntergosternite 7+8, epandrium and cercus brown. Cercus elongate and straight, with rounded tip in lateral view ( Fig. 11A View FIGURE 11 ). Cercal prongs parallel with a rectangular tip in dorsal view ( Fig. 11B View FIGURE 11 ). Cercus without setulae on inner lateral margin and with long and thick setae restricted to basal half ( Figs 11 View FIGURE 11 A–B). Surstylus almost triangular, with an elongate projection in posterobasal corner and a rectangular tip; setulae restricted to posterobasal corner and long and fine setae restricted to base ( Fig. 11A View FIGURE 11 ). Pregonite with widened base and narrowed distal portion curved anteriorly, with a conspicuous rounded projection on ventral margin and a row of short and pointed setae on dorsal margin ( Fig. 11C View FIGURE 11 ). Postgonite shorter than pregonite, tapering distally, with pointed tip curved anteriorly and a long seta and some small pointed setae on ventral margin ( Fig. 11D View FIGURE 11 ). Basiphallus conical, curved ventrally ( Fig. 11E View FIGURE 11 ). Distiphallus with rounded apical margin; ventral margin convex with a small finger-like projection ( Fig. 11E View FIGURE 11 ). Vesica elongate and angled, with a triangular projection in basal half and tip with microtrichia ( Fig. 11E View FIGURE 11 ). Inner process of vesica elongate and curved anteriorly ( Fig. 11E View FIGURE 11 ). Lateral and median styli short, of about one-fourth of width of widest portion of lateral wall of distiphallus, and both inserted medially in distiphallus ( Fig. 11E View FIGURE 11 ).
Female. Unknown.
Etymology. The specific epithet is a noun in apposition and refers to the type locality.
Distribution. NEOTROPICAL—Ecuador (Napo).
Remarks. This species shares with N. paraensis , N. tinguensis and N. similis sp. nov. ventral margin of distiphallus bearing a small finger-like projection, but differs from them in having pregonite with a prominent rounded preapical projection on anterior margin ( Fig. 11C View FIGURE 11 ).
