Wings with long downy hair and, as in O. burtoni and O. australis , male forewings lack scale patches. Males are distinguished by genitalic features (figs 43–45): shape of the inferior appendages which are stout and elongate in ventral aspect, in lateral view narrowly tapered apically and with a dorso-mesial expansion; and pre-anal lobes that are broadly almond-shaped. Male forewing length, 3.9–5.5 mm. Distribution. Known in Australia only from far north-eastern Qld. Described from Bogor (= Buitenzorg), Java, and recorded subsequently from New Guinea ( Kimmins, 1962 , from Kokoda, Papua New Guinea ). Remarks. Oecetis buitenzorgensis is one of several Oriental/New Guinean species recorded from far northern Queensland . Chen, 1992 placing O. buitenzorgensis with a group of Palaearctic and Oriental species (African, Indian and Thai), commented that it is a nomen dubium , not recognisable from Ulmerʼs illustrations. However, the north-eastern Australian specimens agree closely with Ulmerʼs figures, and conform well to other members of the pechana - group as recognised here.
