Cecidomyia (Diplosis) actiosa Skuse, 1888: 105 .

Material studied. Syntypes, male and female, “Peat’s Ferry (Masters and Skuse). August. [the label reads “October”]”, in ANIC. Both the male, designated here as lectotype (ANIC 29-38478), and the female paralectotype (ANIC 29-38479) are well preserved except for a missing cercus in the female.

Description. Male. Wing 2.3 mm long, 0.9 mm wide; R4+5 slightly curved, joining C near wing apex; C broken at juncture with R4+5; Cu forked, reaching wing margin; Rs strong, situated midway between end of R1 and arculus; wingfold reaching wing margin; CuP present, fading close to Cu branching point; Sc fading posteriad of Rs. Head with short occipital protuberance, eye connate but length of eye bridge not assessable due to partial collapse of head. Palpus 4-segmented; segments progressively longer; palpiger present. Flagellomeres 12; binodal, each with 3 circumfila; basal and distal circumfila each with equally long ventral and lateral loops, with one especially long dorsal loop nearly twice length of flagellomere flanked by short loop on either side; middle circumfilum bandlike ( Fig. 5 ). First tarsomeres with small, pointed, densely microtrichose ventrodistal lobe; claws strongly bent before midlength, toothed on foreleg, simple on mid- and hindleg; empodia not reaching bend of claws. Terminalia: gonocoxite cylindrical, unlobed; gonocoxal apodemes separate; gonostylus slightly bulging and microtrichose basally, narrow, glabrous, carinate and sparsely setose beyond, tooth comb-like; aedeagus long, robust, tapering, with 5 pairs of asetose ventrolateral papillae; cerci short, convex; hypoproct entire, slightly shorter and narrower than aedeagus, microtrichose, with two pairs of apicolateral setae.

Female. Wing 2.6 mm long, 1.0 mm wide. Flagellomeres with long necks. Ovipositor barely protrusible, cercus ovoid, with dense group of short setae apicoventrally and scattered long setae elsewhere; hypoproct long and triangular in dorsoventral view, bearing pair of setae apically.
