Key to the species groups of the pygmaeus -complex

1 Prementum with single, median apical tooth. Aedeagus with ¯agellum. Clypeus broadly extended anteriad, median projection at least one third width of rostrum. Pronotum punctate, never transversely rugose...... eucalypti -group

1 ¾ Prementum with two apical teeth. Aedeagus with symmetrical transfer apparatus (TA). Clypeus with simple median incision or with median, apically incised tooth less than one quarter width of rostrum. Pronotum usually transversely rugose, rarely smooth or punctate............... 2

2 (1 ¾) Sternites V±VI of male abdominal venter each with pair of sublateral brushes, usually placed on distinct longitudinal extensions; if venter evenly setose without extensions or setose brushes, Australian species. Eyes large, dorsally contiguous or subcontiguous. Clypeus with simple median incision. Both Australian and Papuan species.............. quadrifasciculatus -group

2 ¾ Sternites V±VI of male abdominal venter without pair of setose longitudinal ridges. Eyes medially distant to approximated, rarely subcontiguous. Clypeus broadly extended anteriad or with median, apically incised tooth. Exclusively Papuan species.................. pygmaeus -group
