S. trichodea

These hair-like structures were on the distal (top) part of each segment ( Fig. 7 A ). One to 2 s. trichodea were on each flagellomere. Each sensillum was ~40 μm long with a basal diameter of 2 μm. External morphology of these sensilla was similar to s. basioconica ; sensilla had smooth surfaces pitted with pores, but were more slender and longer than s. basioconica . S. trichodea could be confused with s. chaetica , although the former lacks a flexible pocket and their surface was pitted, not ridged. TEM examination of s. trichodea revealed the presence of dendrites in the sensilla lumen and wall pore ( Fig. 7 B ).
