Taxonomic remark OBSERVATIONS OF SHUHEI NISHIDA
Oithona minuta T. Scott, 1894
In 1984, I borrowed and examined the type specimens of O. minuta T. Scott., 1894, from British Museum (Natural History). The bottle contained seven specimens: three adult females and three immature copepodids closely similar to O. brevicornis, and one immature copepodid of another un-identified species of Cyclopoida.
The description of O. minuta by T. Scott (1894) agrees with the above adult specimens in the general body shape and the blunt terminal spines of mandible, but differs in presence of two terminal setae on the fifth legs (only one seta in the specimens). There is no mention on the shape of rostrum (sharply pointed in the specimens). These specimens agree with O. brevicornis Giesbrecht, 1891, except for the slight differences such as the presence of spinules in the antennule and lack of hair rows in the abdominal somites.
These observations indicate that O, minuta T. Scott, 1894, is “not” a member of Dioithona but a species closely related to O. brevicornis Giesbrecht, 1891.
The species “Dioithona minuta Shuvalov, 1980” listed in WoRMS is not described as new in Shuvalov (1980); instead the respective species is indicated as “Oithona (Dioithona) minuta T. Scott, 1894” (p. 169, fig. 51). However, only one seta is indicated on its fifth leg (fig. 51K) and the rostrum is not pointed, which does not agree with neither Dioithona nor O. brevicornis.  [details]
