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).

palpus of both sexes in G. cantor
