( Figs 5 , 24–27 ) Diagnosis : Genus belongs to the tribe Homalotini , intermediate between the genera Stenomastax CAMERON, 1933 , and Coenonica KRAATZ, 1857 , both distributed particularly in the oriental region. The very long ligula and the form of the spermatheca are also found in Stenomastax , but the convex body is characteristic of Coenonica , while the flattened, less convex body is found in Stenomastax . Nevertheless the ligula in Coenonica is short and not as long as in the new genus. The preapical narrowed ligula showed by the new genus is not observed either in Stenomastax , or Coenonica . Description : Body similar to Coenonica but with forebody very opaque ( Fig. 5 ). Antennae 11- segmented. Eyes shorter than the postocular region in dorsal view, temporal sulcus present. Labial palpi of two segments ( Fig. 25 ), ligula long, narrowed in the preapical portion ( Fig. 25 ), paraglossae not prodruded in front; maxillary palpi of four, narrow, segments, the apical segment awl-shaped ( Fig. 27 ), interior lobe narrow, the external one shorter than the interior ( Fig. 27 ). Anterior border of mentum posteriorly emarginate ( Fig. 26 ). Mesosternal process acute, mesocoxae contiguous. Tarsal formula 4-4-5. First posterior tarsomere as long as the two following bring together. Spermatheca as in Fig. 24 . Type species : Austraepiskia barrinensis spec. nov. Etymology : The name of the new genus is composed by “ Australia ” and the Greek word έπίσκιοσ = opaque.
