Prostheclina boreoxantha n.sp.

Figs 2, 10, 11; Table 1

Material Examined. HOLOTYPE Queensland: 1 male, Mt Spurgeon area , 16°26'S 145°12'E, J. Thompson, M. Moulds, F. McKillop, 9 Apr 1994, AM KS64638 . PARATYPE Queensland: 1 female, Mt Spurgeon area , 16°26'S 145°12'E, J. Thompson, M. Moulds, F. McKillop, 19 Apr 1994, (copulatory organs missing) AM KS64610 .

Diagnosis. F1–4 yellow, P1, T1 and M1 orange, Ts1 yellow, lush fringes on M1 and T1, palps vanilla colour. Neither dorsal median white strip of hair nor red clypeal moustache, Male copulatory organs with dorsal distal tegular lobe as well as distal and proximal tegular lobes. Female copulatory organs with proximal seminal duct short and straight. Can be separated from P. boreoaitha by the absence of dark colour patches on F1–F4 and the presence of a dorsal, distal tegular lobe, and from P. bulburin, by smaller size (75%), the

presence of a dorsal, distal tegular lobe and the absence of the red mat of hairs covering the clypeus and around AME found in P. bulburin .

Distribution. The species has only been collected at two sites on Mt Spurgeon in northern Queensland ( Fig. 10 ).

Etymology. From Greek bOREAV = northern and cANQOV = yellowish-brown, to be treated as a female noun in apposition.
