Oecetis minasata Mosely

Figures 21–23, 108

Oecetis minasata Mosely in Mosely and Kimmins, 1953: 282, fig.

198. — Neboiss, 1977: 146, figs 784–787.

Material examined. Holotype. Male, Tas. ( BMNH). 21 samples in ANIC and NMV.

Diagnosis. Wings dark brownish, unicolorous, with long downy hair on the veins; forewing length 4 times maximum width, posterior anastomosis contiguous. In male genitalia (Figs 21–23) in ventral view, inferior appendages with basal portion as long as wide, roundly produced ventromesially, and constricted and sharply returned forming dorsolateral lobes; preanal appendages about 3 times as long as wide.

Distribution. South-eastern Australia: from south-eastern NSW, ACT, Vic. and Tas. (Fig. 108).

Remarks. Males of O. minasata are distinguished from those of O. erskinensis by the rounded apex of the phallus, and from O. asmanista by the angular ventral expansion of the inferior appendages and the shorter median process of tergum X. The female lacks the patches of bristles characteristic of O. asmanista . In form of male genitalia, O. cymula and O. paracymula also show resemblance, but O. minasata can be distinguished from the two species by the crossveins of the posterior anastomosis contiguous, not stepped.
