Antipodogomphus proselythus (MARTIN) ( Figs 3, 4 )

The known larvae of four species of Antipodogomphus were keyed by THEISCHINGER (1998, 2000). This together with the following description leaves only the larva of A. edentulus WATSON undescribed. M a t e r i a l: 1 final instar female exuvia from larva collected in Isabella Creek, N of Cooktown,

Cape York Peninsula, Queensland, Australia, 4.1.2007, S. Butler / adult emerged Sydney/Grays

Point, 31.3.2007, G. & C. Theischinger.

Total length 27.2 mm; width of head including eyes 5.0 mm; length of metafemur 3.5 mm; length of abdomen 19.0 mm. Prementum: length 2.7 mm; width at distal end 2.5 mm, at base 1.8 mm.

Prementum only slightly longer than wide; ligula slightly protuberant, its margin finely crenulate. Labial palps subtriangular and almost straight, end hook slightly curved. Pro- and mesotibia with distal claw large. Lateral spines on abdominal segments 7 and 8. Middorsal armature on segments 3-9. Segment 9 of abdomen 2.8 mm long.

R e m a r k s: The combination of almost straight labial palps, almost square prementum with slightly protruding ligula, strongly developed distal outer claws of pro- and mesotibia and short abdominal segment 9 appears to be diagnostic for the larva of A. proselythus .
