Diagnostic description

Holotype (Fig. 5a). Length 3.28 mm. Color black; legs deep ferruginous to black; antenna lighter ferruginous. Body subovate; in dorsal aspect and in profile with weak constriction between pronotum and elytron. Rostrum in basal half dorsally markedly swollen, punctate-reticulate, densely squamose with white erect scales; subapical third subglabrous, weakly punctate, sparsely setose. Eyes medially approximate. Pronotum subglabrous, with minute punctures; laterally punctures somewhat larger; evenly rounded towards sides; in front of procoxa with acute process. Elytra subglabrous with minute punctures; striae indistinct; basal margin straight, towards sides bordered by row of moderately deep punctures. Femora with anteroventral ridge distinct, rounded basally; at middle with small tooth. Mesofemur and metafemur dorsally densely squamose with white scales; metafemur with distinct dorsoposterior edge. Abdominal ventrites 1-2 medially concave. Abdominal venter medially subglabrous, laterally with sparse white scales. Penis (Fig. 5b) apically subangulate, weakly pointed; transfer apparatus beak-shaped, pointed, directed basad; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.98–3.47 mm. Female rostrum in apical 2/3 dorsally flattened, subglabrous, sparsely punctate; basally swollen, with erect white scales.

Material examined

Holotype (ANIC): ARC4238 (PCR failed), Queensland, 11 km ENE of Mt. Tozer, S12°43', E143°18', 11-16-VII-1986. Paratypes (ANIC, QMBA, SMNK): Queensland: 2 exx, same data as holotype; 5 exx, ARC4239 (PCR failed), 3 km ENE Mt. Tozer, S12°44', E143°14', 28-VI-04-VII-1986; 1 ex, 8 km E by N of Mt. Tozer, S12°44', E143°17', beating rainforest vegetation, 07-VII-1986; 3 exx, 9 km ENE of Mt. Tozer, S12°43', E143°17', 05-10-VII-1986; 1 ex, Claudie R., nr. Iron Rg., under bark, rotten logs, 19-25-VII-1978; Gordon Creek area, Claudie Riv. District, 23-I-1982.

Distribution

Queensland: Iron Range.

Biology

Swept and beaten from rainforest vegetation.

Etymology

This epithet is a combination of the Latin adjective australis (southern) and the specific epithet of Trigonopterus nasutus (Pascoe), also an adjective.

Notes

This species is closely related to Trigonopterus nasutus (Pascoe) and Trigonopterus gibbirostris (Faust) from New Guinea. From the former it can be distinguished by a longer and spiniform transfer apparatus, from the latter by its medially pointed apex of the penis.
