Holotype. MCZ 16026, 38.5 mm, St. Paul Island, Alaska, 56.9°N, 170.4°W. Diagnosis. 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 (29.3); ...
