Antenna, dorsal integument, and genital pad morphology of Oroperipatus tiputini sp. nov. under a scanning electron microscope. A. Antenna: in blue, the antennal tip, and in yellow, the sensory field of the antenna; insert in A: spindle-shaped papillae in detail. B. Primary papilla with 10 scale ranks in the basal piece (bp), four scale ranks in the apical piece (ap), and the sensory bristle (sb). C. Dorso-lateral integument: in green, the biggest primary papillae; in purple, the smallest primary papillae (or secondary papillae); and in red, the accessory papillae that possess rudimentary apical pieces; the arrow points to the incomplete plica. D. Posterior region in ventral view showing the opening of the genital pad (gp) and, in orange, the anal glands. Scale bars: 200 µm (A, C, D), 50 µm (B and insert in A).
