FIGURE 5. Morphological traits used for separation of genera of Sididae. A, Diaphanosoma exemplifying the general habitus of Sididae and showing characters used in identification of the genera (A1, antennule; A2, antenna; PA, postabdomen). B, head of Diaphanosoma, showing the antennule with terminal aesthetascs and short flagellum. C, head of Latonopsis Sars, 1888, showing the antennule with terminal aesthetascs and long flagelum. D, antennule of Sarsilatona Korovchinsky, 1985, with terminal aesthetascs and long flagellum. E, antennule of Pseudosida Herrick, 1884, showing aesthetascs on a lateral protuberance and a long apical flagellum. F, Pseudosida, showing lateral groups of anal teeth on the postabdomen. G, postabdomen of Diaphanosoma without anal denticles. H, postabdomen of Latonopsis, showing isolated anal denticles.
