Western Australia. L el.areae sp, nov. from Kopevalc, NE Queensland, and Metatrogus lukei

The Australian Melolonthini were last revised
by Britlon (1978) and the tribe in Australia is now
known to contain 16 genera and 116 species
(Houston St, Weir, 1992; Allsopp. I993a,b,c;
Allsopp Si Watkins, 1995). Most o\ the species
occur in the N and E of the comment, with
Lepidiota Kirby and Derntolepida Arrow
extending into SE Asia and New Guinea,
respectively (Allsopp, 1995).
This paper describes 3 new species; 2 from E
Queensland, and 1 from NW Western Australia.

DIAGNOSIS-Britlon (1978) distinguished
Lepidiota from other Australian Melolonthini by
a combination of: anterior face of clypeus
shallow and usually smooth and unpuuetured in
the middle; anterior edge of clypeus as seen from
above usually broadly bilobed; antennae 10-
( rarely 9-) segmented, with a 3-segmented club;
lamellae usually shorter than antcnnal segments
[-7 (or 1-6) together; surface of the body usually
bearing lew or many broad adpressed. white
scales., scales sometimes minute and wholly
contained within their punctures; tarsal claws
each with a strong tooth in the middle of the
concave side; anterior edge of posterior femora
not concave near the base; mandibles not curved
downwards at their apices.
Sixty species are known to occur in Australia,
mainJv in the north half of the continent (Britlon.
197S; Houston & Weir, 1992; Allsopp &
Watkins J 995).
