Numbers of described species given refer to the Australian fauna only.

1. Body long oval to pear-shaped, widest at posterior third, moderately convex to slightly flattened; cranial neck absent; pronotum subquadrate, with anterior margin slightly wider than or subequal to posterior margin; mesanepisterna meeting at midline………………...................................................………… Eurypinae ……..2

– Body slender, elongate, subparallel-sided, strongly dorsoventrally flattened; distinctly developed and exposed cranial neck present; pronotum cordate, with anterior margin distinctly wider than posterior margin; mesanepisterna widely separated…………………..........................………........…… Hemipeplinae .... ................................................................…................... Hemipeplus (one described species: H. australicus )

2. Body surface densely covered with distinctly clustered yellowish, long setae dorsally…………………………………………………………………………… Loboglossa (one described species: L. australica Champion, 1916 )

– Body surface sparsely covered with regularly distributed small to minute setae dorsally………………………………....................................................................................................................3

3. Pronotum transverse, with posterior margin distinctly wider than anterior margin……… Austrophaeogala

– Pronotum subquadrate or rounded, with anterior margin subequal to or distinctly wider than posterior margin……………………....................................................................................................................................4

4. Body pear-shaped, widened posteriorly; pronotum subquadrate, with lateral sides distinctly widened anteriorly or parallel-sided in few species; sex patch usually present, absent in some species……………….........................................................................................… Trichosalpingus (14 described species)

– Body long oval, parallel-sided; pronotum distinctly rounded laterally; sex patch absent……………............ ............................................................................................................................................. Austroconomorphus region flattened to slightly convex, without distinct deep frontal furrows; compound eyes small, ratio of eye diameter to interocular space c. 1:2.3–3.0, without impressed ocular grooves or carinae, interfacetal setae extremely short, inconspicuous; apical maxillary palpomere ( Fig. 4B View Figure 4 ) securiform; apical labial palpomere ( Fig. 4C View Figure 4 ) oval, narrowing apicad; antennae ( Fig. 4D View Figure 4 ) short, not extending to elytra, simple, antennomere V–X scaphiform, weakly clubbed, XI oval. Pronotum ( Fig. 4E View Figure 4 ) subquadrate, distinctly wider than head, with sides rounded, disc without shallow, paired depressions, lateral pronotal carinae ( Fig. 4F View Figure 4 ) absent; prosternum ( Fig. 4G View Figure 4 ) with procoxal cavities closed externally, widely open internally. Elytra ( Figs 3A, C View Figure 3 , 4H View Figure 4 ) long oval, without apicoventral binding patches. Legs ( Fig. 4I View Figure 4 ) with penultimate tarsomere expanded, not wider than length of distal tarsomere, claws simple, with basal swelling. Abdominal ventrite(s) of male ( Fig. 5A View Figure 5 ) without sex patch.

Etymology: The genus name is composed of the Latin prefix Austro-, southern, derived from Australia, and the root - conomorphus, cone-shaped, derived from the related genus group Conomorphus (i.e. conomorphine group sensu Pollock, 2006). Gender: masculine.

Distribution: Presumably endemic to Australia.
