Sensilla placodea
In the mandibular palpus, the SP (♀ = 2.65 ± 0.14 μm, ♂ = 1.27 ± 0.05
μm, t = 9.20, P < 0.01) was significantly wider
basally in females than in males. The basal width of the SP of the
mandibular palpus was significantly wider in females than in males, but
the length of the SP of the labial palpus was significantly longer in
males than in females (Table 5). The number of SP in females was much
greater than that in males in the mandibular palpus (♀ = 21.20 ± 1.02, ♂
= 12.40 ± 0.24, t = 8.39, P < 0.01) (Figs. 3).
