A species of Eumicrotremus distinguished from all other ENP species of Eumicrotremus by the following combination of characters: tubercles, when present, irregularly arranged in interorbital space (vs. four distinct interorbital rows in E. orbis ); enlarged pair of tubercles absent at origin of second dorsal and anal fin (vs. present in E. andriashevi ); thick dermal papillae absent (present in E. barbatus ). Eumicrotremus gyrinops is distinguished from members of the WNP E. asperrimus species complex (including E. asperrimus , Cyclopteropsis bergi , and C. lindbergi ) by higher modal counts of dorsal-fin spines (usually VII vs. usually VI) and lower modal counts of pectoral-fin rays (24–28 vs. 25–30). Counts and proportions. First dorsal-fin spines VI–VIII; second dorsal-fin rays 10–12 (10.6); anal-fin rays 9– 12 (10.1); pectoral-fin rays 24–28 (26.1); vertebrae 10–12 + 15–19 = 26–30 (27.9). Following proportions as percent SL: head length 28.9–45.1 (36.9); body depth 28.7–57.7 (45.6); first dorsal-fin base 16.1–29.9 (23.5); second dorsal-fin base 15.4–26.2 (21.5); anal-fin base 13.7–25.4 (18.0); pectoral-fin base 24.8–35.8 ...
