Diagnosis. Lycodapus pachysoma is distinguished from its congeners by the following combination of characters: vertebrae 16-18 + 59-65 = 75-82; gill raker ratio as percent 50-88; adults with relatively robust bodies and long heads.
Description. Complete descriptions found in Peden and Anderson (1978) and Anderson (1988). Vertebrae 17-18 + 60-62 = 77-80; D 70-72; A 61-62; P 7-8; C 9; pelvics absent; branchiostegal rays 6; gill rakers 13 + 11-12 = 12-15; vomerine teeth 3-17; palatine teeth 7-17; pseudobranch filaments 1-3; pyloric caeca 2; preopercular pores 4; mandibular pores 4; interorbital pore 1. Following proportions as percent SL: head length 20.1-22.2; head width 8.3-9.1; head depth 11.7-12.6; predorsal length 24.1-26.2; preanal length 40.9-42.8; body depth 7.1-8.6. Following proportions as percent HL: upper jaw length 50.2-51.6; eye diameter 12.1-15.9 (21.9 in 52 mm juvenile); snout length 35.3-37.9; pectoral-fin length 19.6-23.8. Gill raker ratio 59-65%.
