3.2.1 Mandible
The mandible sensors of adult G. cantor are relatively simple and
highly ossified and are mainly used for feeding and making oviposition
grooves. The lateral and medial sides of the palate have numerous
receptive hair areas, with a small number of hair-shaped sensors type I
(ST I) distributed on the outer side (Fig. 1), while the ventral and
dorsal edges of the palate have sensilla chaetica (SCh) III in addition
to ST I, and the dorsal surface has significantly more sensilla than the
ventral surface (Fig. 2). Females have significantly more ST I and SCh
III on their mandibles than males.
