Sensilla types on walking and ultimate legs. a Sensillum macrotrichodeum I. Note the orientation of the sensillum’s shaft nearly perpendicular to the cuticle. Scale bar 10 μm. b Sensillum mesotrichodeum I. Scale bar 10 μm. c Sensillum mesotrichodeum II. Note the association with two pores of solitary epidermal glands (arrows), and the characteristic appearance of the shaft. Scale bar 5 μm. d Detail on the sensillar shaft as indicated in c illustrating the sponge-like cuticle between the ribs. Scale bar 500 nm. e Apex of s. mesotrichodeum II featuring a small terminal pore (arrowhead). Scale bar 1 μm. f Sensillum microtrichodeum with terminal pore. Scale bar 2 μm. g Crescent shaped socket of s. macrotrichodeum I. The sensillum is accompanied by a single glandular pore. Scale bar 2 μm. h Close up on multidentate socket of s. macrotrichodeum II.
