Etymology. The species name is descriptive for the pointed caudodorsal process of the pygofer.

Remarks. G. acuta   resembles G. khasiensis (Rao)   in general habitus and in the structure of male genitalia. It differs from G. khasiensis   in having a more acute caudodorsal process of the pygofer. Specimens from Manipur have the pygofer process slightly asymmetrically developed, one being longer and serrated and the other typical.
