Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.234, Fig.82]. Female: a, habitus (left side); b, urosome (dorsal); c, d, forehead (left, dorsal, respectively); e, f, genital somite (left, ventral, respectively); g, left Mx2 (posterior); h, right Mxp (anterior); i-k, basis of right Mxp from 3 different specimens (anterior). Nota: Prosome length 72 % length of body and about 2.5 times length of urosome. Forehead (laterally) with rounded anterior end and produced ventrad into a conical rostrum bearing 2 elongate filaments. A1 extending beyond posterior end of caudal ramus by last 3 or 4 segments. Mx2: 2nd seta of 1st lobe about 1/2 length of 1st. Posterior subterminal spine of 4th lobe 63% as long as 2nd saberlike spine. Saberlike spine of 5th lobe 88% as long as falcate spine; falcate spine with proximal 64% of medial margin serrated with spinules. Falcate spine of 6th lobe with proximal 74% of medial margin serrated with spinules. Mxp: basis with a small elevated pore in addition to 1 or 2 extraordinarily large elevated piores distal to 3rd middle marginal seta. Genital field with 3-5 pores on left side and about 15 pores on right side. Length ratios or 4 urosomal somites and left caudal ramus 35.8 : 17.0 ; 13.9 : 9.7 : 23.6 = 100.
