Metopa cf. bulychevae Gurjanova, 1955

Fig. 15

Metopa bulychevae Gurjanova 1955: 170–172 , figs. 3, 4

Material examined: Small (juv.?) specimen (1.5 mm) in not very good condition, from 23°20'N, 118°30'E (coast of China) and 17 Fr depth, slide ZMUC CRU-20195 .

Remarks. There is a (probably basic) group of Metopa species with a first gnathopod having a widened propodus which shows a palmar corner: the Atlantic species M. aequicornis Sars, 1879 , M. alderi (Bate, 1857) , M. boeckii Sars, 1895 belong here, as well as M. spectabilis Sars 1879 , if it is not a synonym to M. alderi ; but also the Pacific species M. samsiluna Barnard, 1966 and the Japanese ones, M. uschakovi Gurjanova, 1948 and M. bulychevae Gurjanova, 1955 . Both are not completely described, but Metopa uschakovi has a Gn1 which is much more slender with a carpus much longer than broad, and in U3 the peduncle is less spinose, while the characters of gnathopods, P7 and U3 would fit quite well to M. bulychevae .
