Diagnostic characters.
Most similar to Katatopygia antica , with which it shares the projected dorsomesal corners of the male gonocoxites. Distinguished from Katatopygia antica by having two parameres, hypandrial lobe without median tooth and pale halter.
Re-description.
Male. Wing length 4.5 mm.
Head brown; palps and mouthparts pale. Antenna with scape, pedicel and basal part of first flagellomere pale, rest of flagellum brown.
Thorax pale with 3 distinct, dark brown mesonotal stripes on yellow ground, humeral area pale. Mediotergite with a darker central stripe; preepisternum darker ventrally. Halter whitish.
Wings weakly brownish tinged; stem of M approximately 1.9 times the length of ta; Sc2 present; Sc bare and ending in C slightly before base of Rs. C ending in apex of R5.
Legs pale brown.
Abdomen brown often with narrow pale bands on tergites II-III.
Terminalia brown. Gonocoxite with dorsomesal corner forming a mesocaudally directed horn-like processus, distinctly more projected than the ventromesal corner. Hypandrial lobe well developed and only shallowly emarginated medially, without medial tooth. Two slender parameres, bearing microtrichia. Tergite IX subrectangular, with a sclerotized mesal suture. The apical processus on gonostylus approximately half as long as the diameter of gonostylus and slightly branched with two strong setae. Interior surface of gonostylus without strong setae.
Female. Coloration as in male except pale apical bands on tergite II-V.
Terminalia. Tergite VIII broad with rounded apicolaterally margin; sternite VIII and gonocoxite VIII short and broad with about 6 strong apical setae; gonapophysis IX long and projected into a pointed apex.
Distribution.
Nearctic, known from Canada, British Columbia and USA, Alaska.
