Type locality. Queensland, Australia .

Diagnosis. Elytra with parallel sides, intervals densely punctate; femora with apical third black, basal two-thirds brown; tibiae and tarsi yellow; protarsomere 3 asymmetrical in male; tarsal claws with 5 pectinations, length of the longest pectination subequal to half width of claw base ( Fig. 66 ); aedeagus with apical lamella thin, digitiform, unthickened at apex ( Fig. 91 ).

Description. Length 9.0– 9.9 mm, width 2.5–2.8 mm. Black, head and pronotum with blue luster mixed with slight green luster; elytra with green luster mixed with slight blue luster; apical two thirds of Ant 1 black, basal third dark brown, Ant 2 and Ant 3 dark brown, Ant 4–11 brown; apical third of femora black, basal twothirds brown; tibiae and tarsi yellow. Head much wider than pronotum, HW/PW 5 1.34 (1.27–1.37); vertex convex, coarsely punctate; Ant 1/Ant 3 5 3.31 (3.23–3.38); labrum with medial lobe slightly protruded anteriorly; genae short, oblique; eyes large, about 2.8 times as long as genae ( Fig. 31 ). Pronotum coarsely punctate, narrow, PL/PW 5 1.64 (1.60–1.71); lateral margins slightly sinuate before basal angles; basal angles almost rectangular; basal foveae deep. Elytra long, lateral margins almost parallel, EL/EW 5 2.04 (2.00–2.06), EW/PW 5 2.21 (2.16–2.30); outer angles slightly dentate, pointed; intervals convex, densely punctate, interspace between two adjacent punctures narrower than diameter of punctures. Protarsomere 3 slightly asymmetrical in male; tarsal claws with 5 pectinations, length of the longest pectination subequal to half width of claw base ( Fig. 66 ). Aedeagus with apical lamella thin, narrow, not thickened at apex ( Figs. 91–92 ).

Distribution. Known from Queensland and Northern Territory, Australia.

Etymology. The new species is named for its type locality.

Remarks. This new species at first appears to be just a variety of D. ternatensis Chaudoir , based on the similarity in genitalia. However, the longer black portion of the femora and longer, parallel-sided elytra of its members are quite different from those of D. ternatensis members, so we treat this as a distinct species.
