Cecidomyia (Epidosis) pallida Skuse, 1888: 120 .

Cecidomyia pallidina Gagné, 1989: 156 ( Gagné 1989b) , new name for Cecidomyia pallida Skuse (preoccupied by Meigen 1830).

Material studied. Syntypes, male and female, “ Elizabeth Bay (Skuse). July ”, in ANIC . The male, designated here as lectotype (ANIC 29-38494), has preserved wings, partially shrivelled head with palpi and several basal flagellomeres, thorax with three legs, and abdomen with terminalia. The female (paralectotype, ANIC 29-38495) retains a wing, the distal 11 flagellomeres of one antenna, and anterior part of the abdomen.

Description. Male. Wing 2.1 mm long, 0.7 mm wide; R4+5 strongly curved at apical third, joining C at wing apex, C broken at juncture with R4+5, Rs closer to end of R1 than arculus; Cu forked, Cu2 stronger than Cu1; wingfold weak. Head: palpus 4-segmented, palpiger present; flagellomeres 14 ( Skuse 1888), node with single horizontal circumfilar band, neck 2x longer than node. Tarsal claws simple, as long as empodia. Terminalia: gonocoxites with acute apical lobe dorsally; gonocoxal apodemes separate, reaching base of gonocoxites; gonostylus stout, with inner edge straight, outer edge curved, abruptly tapered towards apical comb-like tooth, entirely microtrichose and setose; cerci large, elliptical, with several apical setae; hypoproct deeply concave apically, entirely microtrichose, with single seta on each lobe; tegmen (= merged parameres) stout, blunt, longer than cerci, ejaculatory apodeme starting at base of gonocoxal apodemes and reaching 2/3 length of aedeagus.

Female. Wing 2.1 mm long, 0.8 mm wide. Antennal flagellomeres progressively shorter, neck 1/3 node length, circumfila consisting of a partial basal strand whose ends run vertically to join a complete transverse distal strand. Remarks. See remarks under D. indubitata , the next species.
