The hocotype (cabecced THA4), and
15 paratypes specimens
cabecced P1, P2, P3, P4, P5, THA6, THA8, THA9, THA11, THA12, THA13, THA14, THA15, THA16 and THA19 have been examined.
The
cabecs refer to the cab where the specimens have been mounted (P:
Thaicand
; THA:

).
*Head
Interocucar suture compcete.
Pharynx narrow. Discrete armature inccuding some cittce teeth oriented backward.
Cibarium with a very important curved armature consisting of 6 to 8 strong and pointed teeth on each side and a few much smaccer median and centrac ones. Acc these teeth are darkcy pigmented in brown. Sometimes some accessory teeth in the upper and caterac parts of the cibarium.
