Scipopus brevifurca – Czerny 1932: 274 (listed). — Hennig 1934: 322 (key), 325 (diagnosis); 1937: 48 (listed). — Steyskal 1968: 48.15 (catalog). — Schumann 1988: 88 (catalog).

Differential diagnosis

Scipopus (Phaeopterina) brevifurca resembles S. (Ph.) rufilabris , S. (Ph.) gorgonae , and S. (Ph.) uniformis sp. nov. in having uniformly dark brown wings and hind legs, but differs from consubgeners by the dark brown or black epicephalon.

Type material examined

Holotype (photographed in Berlin, 2002)

ECUADOR • 1 ♂; Santa Inéz. Distr. ; R. Haensch leg.; MNBG.

Description

HEAD. Palpus and clypeus orange. Frontal vitta dull, orange, microtrichose. Epicephalon shiny, dark brown, wide (width ⅔ or more of upper frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. All head chaetotaxy well-developed.

THORAX. Scutum dark brown or black with silvery-blue sheen. Female cervical sclerite not observed. Postpronotal lobe and notopleuron dark brown.Thorax dark brown or black, entirely silvery microtrichose. Legs dark brown, paler brown basally; first fore tarsomere dark brown with ventral golden fringe, first hind tarsomere white. Wing uniformly brown infuscate.

FEMALE ABDOMEN. Not observed.

MALE ABDOMEN. Trichosity and ratios of tergites not observed. Genital fork with arms converging, inner basal process very short, barely distinguishable from arm. Epandrium elongate (length 2.0× height). Basiphallus not observed. Basal distiphallus long (≈ in length to epandrium). Phallic bulb, distal distiphallus, phallapodeme and hypandrium not observed.

Distribution

Ecuador. Hennig (1937) listed “Brazi, Pebas” as a locality, which more likely refers to Pebas, Peru.
