238 Abstract — A new species of the cottid genus Triglops Reinhardt is described on the basis of 21 specimens collected in Aniva Bay, southern Sakhalin Island, Russia, and off Kitami, on the northern coast of Hokkaido, Japan, at depths of 73-117 m. Of the ten spe-cies of Triglops now recognized, the new species, Triglops dorothy, is most similar to T. pingeli Reinhardt, well known from the North Atlantic and North Pacific oceans and through-out coastal waters of the Arctic. The new species differs from T. pingeli in a combination of morphometric and meristic characters that includes most importantly the number of dorso-lateral scales; the number of oblique, scaled dermal folds below the lateral line; and the number of gill rakers.

Sculpins of the teleost family Cottidae are nearly ubiquitous in cold-water benthic habitats of the Northern Hemi-sphere, comprising nearly 200 species in the North Pacific alone (Yabe and Nakabo, 1984; Sheiko and Federov, 2000; Mecklenburg et al., 2002; Love et al., 2005), where they are found in almost every benthic habitat from the intertidal to the upper continental slope. Many species are preyed upon by larger fishes and marine mammals (Browne et al., 2002), and are them-selves predators primarily of smaller fishes and crustaceans (e.g., Tokranov, 1998; Hoff, 2000; Tokranov and Orlov, 2001). Although many members of the family are also commonly found in bycatch of commercial fisheries (Stevenson, 2004; Orlov, 2005), the systematics and life histories of most species are poorly known (Nelson, 1994; Hoff, 2000; Hoff, 2006) and new species continue to be described (e.g., Yabe, 1995; Yabe and Maruyama, 2001; Yabe et al., 2001). A more com-plete understanding of the diversity of the family is necessary to understand the role of cottids in the dynamics of North Pacific ecosystems. The cottid genus Triglops Rein-hardt (1830), including Prionistius Bean (1884), Elanura Gilbert (1896), and Sternias Jordan and Evermann (1898) as junior synonyms, contains 19 nominal species and subspecies, of which nine are currently recognized as valid (Pietsch, 1993). Members of the genus are characterized most strikingly by having a small head, a narrow, elongate body and a slender caudal peduncle, a long anal fin con-taining 18-32 rays, pelvic fins with a single spine and three soft rays, branchiostegal membranes united on the ventral midline but lying free from the isthmus, and scales below the lateral line modified to form dis-crete rows of tiny serrated plates that lie in close-set, oblique dermal folds. The species are generally distributed in rather deep water (primarily be-tween 18 and 600 m, but specimens have been taken more or less on the surface and as deep as 930 m; An-driashev, 1949; Hart, 1973; Fedorov. 1986) throughout cold-water, conti-nental shelf or slope regions of the North Pacific, North Atlantic, and Arctic oceans. All appear to feed pri-marily on small planktonic and ben-thic invertebrates (Andriashev, 1949; Fedorov, 1986). Spawning takes place from late summer to winter; the eggs are demersal (Andriashev, 1949; Mu-sick and Able, 1969; Fedorov, 1986). Triglops was first proposed by Jo-hannes Reinhardt (1830), based on a single specimen from West Green-land, but the type species T pingeli
