Key to Species of Australycra

1. Elytral megasetae somewhat longer and thicker than microsetae and strongly overlapping one another within a longitudinal row ( Fig. 43 ); both megasetae and microsetae decumbent; rows of shallow pits and associated microsetae less regular, with pits sparser and very finely margined; pronotal punctures somewhat finer and sparser, usually separated by a diameter or more, their interspaces more distinctly sculptured and slightly shiny; vertexal line complete; apex of tegmen ( Fig. 85 ) broadly emarginate; apex of penis as in Fig. 81 ; tegmen and penis ( Fig. 91 ) singly curved in lateral view............. A. obscura (Blackburn)

- Elytral megasetae about as thick as and only slightly longer than microsetae and less strongly overlapping one another within longitudinal row ( Fig. 44 ); megasetae and microsetae usually inclined, rather than decumbent; rows of shallow pits and associ- ated microsetae ( Figs 4 , 44 ) more regular, with pits denser and more distinctly margined; pronotal punctures coarser and denser, separated by less than a puncture diameter, their interspaces not or very finely sculptured and shiny; vertexal line incomplete at middle; apex of tegmen ( Fig. 88 ) with narrow median incision; apex of penis as in Fig. 82 ; tegmen and penis ( Fig. 92 ) doubly curved in lateral view..................................................................... A. similis sp. nov.
