| Summary: | Wellstenhelia melpomene sp. nov. Synonymy. Stenhelia hanstroemi Lang – Kornev & Chertoprud 2008: p. 201, fig. 5.96. Type locality. Russia, White Sea, Kandalaksha Gulf, Velikaya Salma Bay, between 30 and 100 m, approximate coordinates 66.497°N 33.621°E. Type material. Hollotype female illustrated by Kornev & Chertoprud (2008) in fig. 5.96, dissected on two slides; paratypes, numerous males and females in alcohol; all deposited at P.P. Shirshov Institute of Oceanology, Russian Academy of Sciences, Moscow, Russia; not examined. Etymology. The species is named after Melpomene (Ancient Greek: Μϵλποµένη), one of nine Muses from Greek mythology, who was a patron of tragedy. The species name is a noun in apposition (in the nominative case). Description. Female as described by Kornev & Chertoprud (2008) from the White Sea, and illustrated in their figure 5.96 as Stenhelia hanstroemi Lang, 1948. Male not described or illustrated. Morphological affinities. Kornev & Chertoprud (2008) state that this species is very common in the White Sea, on muddy bottoms between 30 and 100 m, although it is not clear if they found any males. They provide a brief description and skilful drawings of the female habitus in lateral view, caudal ramus in dorsal view, first swimming leg, fourth swimming leg, and fifth leg. In the armature formula of the swimming legs they state that the third exopodal segment of the first leg bears three outer spines, while their fig. 5.96B shows a normal condition, with two outer spines. We consider the former a lapsus calami. Also the number of setae on the second endopodal segment of the second leg is questionable, as no other member of Wellstenhellia gen. nov. bears two setae and there is no evidence that either Lang (1948) or Kornev & Chertoprud (2008) studied this appendage in detail. They mention that their population differs slightly from that described by Lang (1948) just in the shape of the fourth leg endopod. However, Wellstenhelia melpomene sp. nov. and Wellstenhelia hanstromi ... |
