Males (n = 11): L = 0.88 -1. 22 mm; a = 35-45; b = 5.7- 7.9; c = 14-16; T = 42-49; spear = 32-35 JA. Body nearly straight in death, only male tail curved slightly to ventral side. Cuticle with peculiar punctation which may be a fixation artefact; composed of two well-demarcated layers. Annulation very fine (1 JA, on tail occasionally even less) but distinct. Lateral field with six longitudinal lines, the inner ones originating about level of base of oesophagus. The lateral field is very indistinct owing to the punctation. Deirids not visible. No longitudinal striation outside the lateral field. Lip region offset, knob-shaped, with six to seven annules; offset by a deep constriction. Perioral disc slightly raised, not refractive. Internal sclerotization of lips moderately developed, cheilorhabdions more distinct than in many other ... : Published as part of P. A. A.
