Pelioptera barrinensis spec. nov.

( Figs 13 , 49–51 )

Type material: Holotype , Australia, Queensl., Atherton TL., Lake Barrine NP., 30.X.1989, leg. E. Heiss ( CSCÜ).

Description: Length 2.7 mm. Body shiny, reddishbrown, posterior half of free abdominal tergites 1 and 2 reddish, antennae brown with the three basal antennomeres reddish-brown, legs yellowish-red. Eyes longer than the postocular region in dorsal view. Second antennomere shorter than the first one, third as long as the second one, fourth to tenth transverse. Reticulation of the head very superficial, that on the rest of the body wanting. Head dotting indistinct, that of the pronotum a moderately close and superficial, that of the base of the fifth free tergite of the male strong and consisting of elongate punctures. Granulation of the elytra sparse and evident, that of the abdomen reduced to a few granules near the posterior margin of each free tergite. Aedeagus as in Figs 49-50 ; sixth free tergite of the male as in Fig. 51 .

Comparative notes: The new species differs from P. macropuorum PACE, 2003 , also from Australia, by the much larger aedeagus (0.32 mm long, whereas in macropuorum is 0.24 mm). The aedeagus of the new species is deeply curved in the ventral side, that of macropuorum is less deeply. The body colour of the new species is reddishbrown, that of macropuorum black pitch.

Etymology: The new species coming its name from Lake Barrine.
