vratislavi group

Medium sized, depressed, almost unicolourous species with evenly rounded, explanate basal pronotal angle; labrum wide, 4-setose, anteriorly barely excised; tooth of mentum prominent; mentum bisetose; gular sutures rectangular; glossa quadrisetose; antenna elongate, slender; supraorbital and preorbital setae present; anterior and posterior marginal setae of pronotum present; elytra with 15 marginal setae; female terminal sternum with 4-6 setae on either side; gonocoxite large and compact, acute, with 2 nematiform seta, but without dorso-median and ventro-lateral ensiform setae.

A single species recorded from interior New South Wales.

Systematic position. This group is outstanding, because it combines external and genitalic character states of different species-groups. Particularly the chetotaxy of the dorsal and ventral surfaces and of the female gonocoxite is unique within the genus and excludes this group from all other groups within the genus.
