Large species with mesonotum, metanotum and tergites slightly punctuated. Pronotum with a very peculiar shape ( Fig. 2A ) comprising two pairs of very well delimited protuberances, the hind ones at the summit of the usual hind protuberances, the fore ones very sharp, and a protruding fore margin.

Fore femora ( Fig. 1C ) with ventro-anterior margin with five spines, the larger ones in the middle of the row.

Subgenital plate with posterior margin not strongly sinuous.

Female genitalia ( Fig. 1 K-M)

Basivalvulae ( Fig. 1L ) with anterior and posterior margins clearly delimited and convex, with a distinctive sclerotized appendix following the median membranous groove. Laterosternite IX ( Fig. 1M ) small, with a sharp and short ventral part. Spermatheca large ( Fig. 1K ) with long and locally widened ducts, the apical ampulla oval-elongated, the basal ampulla also elongated and with a long and twisted apex.
