Suarez-Morales & C. Alvarez-Silva in Pacific Sc., 2001, 55. [p.185, Figs.1-5]. As Cymbasoma tumorifrons. Female (from Zihuatanejo, W Mexico): 1-2, habitus (dorsal and ventral, respectively); 3, head and oral papilla (lateral left side); 4, right A1; 5, details of cephalic sensillae (dorsal; (figure rotated 90°). Designation armature elements of A1 follows Grygier & Ohtsuka, 1995: 6aes: aesthetasc very strongly developed. Nota: Cephalothorax slightly more than 55 % of total body length. Oral papilla moderately protuberant, located 25 % of way back along ventral surface of cephalothorax. forehead with 2 sensillae. Ocelli present, pigment cups large, very close to each other, barely separated by a distance less tha 20 % the diameter of the cup. Eyes almost unpigmented, round in dorsal view, asymmetrically arranged as seen in dorsal and ventral views. A1 relatively short, representing almost 18 % of total body length, and about 31 % as long as cephalothorax; 2 apparent segments, purported segments 2-4 demarcated by constrictions along margin (broad arrows in fig.4); length ratio of antennular segments (considering fusion) 14.3:85.7 = 100., and considering all 4 purported segments (proximal to distal) 14.3:32.4:10.8:42.5 = 100.
