Each side of head with a group of six stemmata, two anterodorsal ones larger than remaining ones. Clypeolabrum asymmetrical. Nasale asymmetrical, without distinct teeth, projecting anteriad, truncate anteriorly. Epistomal lobes large, strongly asymmetrical, projecting much further than nasale, left lobe projecting slightly further than right one. Gular sulcus reduced, restricted to posterior quarter of head length. Posterior tentorial pits small, closely aggregated. Ventral anteromedian portion of parietale completely fused with submentum, submental sulcus absent. Pair of cervical sclerites present, but small and widely separated from each other.

Mentum with pair of small setae (LA3) ventrally on distal margin of sclerite and pair of pores (LA4) posterolaterally of LA3. Prementum ventrally with pair of moderately long setae (LA6) on distal margin of sclerite and pair of short setae (LA5) close to basal margin; dorsal face with long setae LA10 and pair of pores slightly posteriorly of LA9.
