First record of the Cheekscaled frill-goby, Bathygobius cotticeps (Gobiiformes: Gobiidae) from Jeju-do Island, Korea

Abstract

A single specimen of Bathygobius cotticeps (41.0 mm SL) was collected from the rocky pools of intertidal zone of Jeju-do Island, Korea. This species is characterized by having VI–I, 9 dorsal fin rays, I, 8 anal fin rays, scales on cheek and opercle, 23 predorsal scales, 38 longitudinal scales, 24 pectoral fins, 7 free rays on upper pectoral fin, each divided to 5–7 branches, cephalic sensory canal pores H and K fused, and the middle of pelvic frenum curved inwards smoothly. We propose a new Korean name, “Bi-neul-mu-nui-mang-duk” for the B. cotticeps based on the presence of scales on the cheek.
