3.2.2 Labial palpus
The labial palps of G. cantor have a rich variety of sensor species, with no differences between male and female sensor types but some variability in the number of sensors (Fig. 3). The sensor species on the labial palps can be divided into seven main groups (11 subtypes): sensilla chaetica (SCh IV, SCh V), sensilla twig basiconica (STB I, STB II, STB III, STB IV), Böhm’s bristle sensor (Bb), sensilla trichodea (ST II), sensilla plate (SP), sensilla coeloconica (SC) and sensilla campaniformia (SCa) (Table 4).
