Differential diagnosis

Scipopus (Phaeopterina) vee sp. nov. is easily distinguished from consubgeners by the white first fore tarsomere, the basally yellow femur and the brown infuscate wing.

Etymology

The species name, from the English word for the letter V, is a noun in apposition referring to the V-shaped single spermatheca of the species.

Type material examined

Holotype

PERU • 1 ♀; Cock of the Rock Lodge; 13°03′21″ S, 71°32′46″ W; ~ 1380 m a.s.l.; 8–20 Oct. 2006; J. Skevington leg.; Malaise Trap; CNC (dissected and photographed, Fig. 71A, C–D, G ).

Paratype

PERU • 1 ♂; same collection data as for holotype; CNC Diptera #96407/MYCRO601-19 sequenced for CO1; CNC (dissected and photographed, Fig. 71B, E, H ) .

Description

LENGTH. 9–10 mm.

HEAD. Palpus orange, pale microtrichose and setulose on entire surface, broad (length 3.8 × height). Clypeus pale orange, width ~1.9 × height, bare. Frontal vitta dull, orange, microtrichose. Epicephalon light brown, shiny, bare, wide (width ⅔ or more of upper frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. One pair of lower fronto-orbital setae absent; all other head chaetotaxy well-developed.

THORAX. Scutum black-brown, dark brown microtrichose, with a wide, silvery-blue median sheen. Female cervical sclerite strongly pointed posteriorly. Postpronotal lobe black-brown, some setulae on vertical margin. Notopleuron black-brown with spot of pale microtrichia outlining anterior notopleural seta. Thorax black-brown with blue sheen, entirely silvery microtrichose. Legs dark brown, mid and hind tibia yellow on basal ⅓ to ½, gradually fading to dark brown apically; fore tarsomere 1 almost entirely white; hind tarsomere 1 dark brown. Wing brown infuscate.

ABDOMEN (J+ ♀). T1 with fine, long, white setae. Relative width of T2 to T1 unknown (abdomen of both types misshapen).

FEMALE ABDOMEN. Pleuron pale grey, P1–2 grey, dorsal and ventral third of P3–5 darker grey, forming indistinct convex pale band across pleuron (not evident in Fig. 71G ). T1+2 ~1.9 × length of T3. Oviscape dark brown, white microtrichose an anterior ½, ~2.8× length of T6. Posterior margin of T2 1.5× as wide as T1 dorsally. Paired and single spermathecal ducts arising separately from bursa copulatrix. Paired spermathecal duct short (6.0 × length of paired spermathecae), parallel-sided, swollen distally and apically. Paired spermathecal stems narrow, slightly sinuate. Paired spermathecae apically rounded, inornate. Single spermathecal duct narrow, of same diameter and length as paired duct, swollen apically. Single spermatheca bifurcate, V-shaped, wider apically, with scattered tubercles.

MALE ABDOMEN. Pleuron pale grey, P1–2 darker grey. T1–5, T1+2 ~1.9 × length of T3. Genital fork 1.4× as long as T6, arms converging; inner basal process absent. Epandrium stout, (length ~1.2 × height), posterior margin pointed, posteroventral margin setose. Basiphallus frame-like, extending beyond junction with distiphallus. Basal distiphallus long (≈ length to epandrium), ending in phallic bulb. Phallic bulb short (length ≈ height), approximately round, upper chamber with rounded posterior projection, lower chamber rounded. Distal distiphallus of available specimen narrow, apparently long but broken off near phallic bulb. Phallapodeme very broad and expanded apically, length ≈ height. Anterior hypandrium expanded and broad.

Distribution

Peru.
