Abstract:
Based upon a thesis (Johnsen 2001) on the taxonomy of
the uristid genus Onisimus Boeck, 1871, the latter is divided into five
species groups to be treated in this and forthcoming publications; a key to
these groups includes the genera Menigrates Boeck and
Paralibrotus Stephensen. Further keys and redescriptions are presented
to all species within two Onisimus species groups. The O.
brevicaudatus-group comprises the species O. affinis Hansen, 1886 (=
O. dubius Schellenberg, 1935, syn. n.), O. botkini Birula, 1897,
O. brevicaudatus Hansen, 1887, O. caricus Hansen, 1887, and O.
derjugini Gurjanova, 1929. The O. sextonae-group consists of the
species O. abyssi Oldevig, 1959, O. leucopis (G.O. Sars, 1879),
and O. sextonae Chevreux, 1926.
Key words: Uristidae; Onisimus; O. brevicaudatus-group; O. sextonae-group
