Barnard, 1969: 346 .— Barnard & Karaman, 1991: 424 (key), 494. Type species. Kyska dalli Shoemaker, 1964 , original designation Included species. Kyska includes one species: K. dalli Shoemaker, 1964 . Diagnostic description. Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum forming cap covering callynophore. Antenna 2 with brush setae. Mandible molar a setose tongue. Maxilla 1 outer plate a well developed 7/4 crown. Maxilla 2 inner plate significantly shorter than outer plate. Gnathopod 1 chelate ; coxa 1 large, about as long as coxa 2, subrectangular with concave anterior margin ; ischium short (length less than 2 × breadth); carpus compressed; propodus margins tapering distally. Uropod 2 inner ramus not constricted. Telson notched . Remarks. Only three uristid genera ( Euonyx , Kyska and Stephonyx ) have chelate first gnathopods. Unlike Kyska , Euonyx and Stephonyx both have reduced vestigial coxae on gnathopod 1. Based on the well developed coxa of gnathopod 1 with a concave anterior margin and a compressed carpus Kyska is similar to Abyssorchomene and Koroga . Kyska differs from both genera in the chelate first gnathopod, from Koroga in less well developed eyes and a deeply cleft telson (notched in Koroga ) and from Abyssorchomene in the straight mandibular incisors (curved in Abyssorchomene ) in the small setose molar and in the tapering margins of the gnathopod 1 propodus. Distribution. Arctic . Alaskan endemic.
