Ferrari in Zoosyst. Rossica, 1995 (1996), 4 (1). [p.68, Fig.29-34]. Male (from 13°23.9'N, 102°35'W): 29-30, habitus (dorsal and lateral, respectively); 31, rostrum (ventral); 32-33, last segment of prosome and urosome (dorsal and right lateral, respectively); 34a, A1 (1st-14th segments); 34b, A1 (15th-24th segments). Scale bars: 0.1 mm. Nota : Prosome nearly 5.6 times as long as urosome. Rostrum one-pointed. Posterior corners of the last segment of prosome rounded, reaching the posterior border of genital segment. Genital segment slightly asymmetrical. Caudal ramus with 4 large apical setae, 1 small lateral seta. Left A1 25-segmented (8th and 9th segments partly fused) ; right A1 geniculated, 25-segmented (all segments inflated), with 8th-9th segments fused, ; 3 segments proximal to the geniculation each have a thick and stiff proximal seta, the 2 segments distal to the geniculation each have comb spines.
