Copidognathus pacificus Makarova, 1974

( Figs. 17–18 )

Type series.ɹHolotype: ˁ NSMT-Ac 14702 (1/8031).

Condition.ɹThe idiosoma and first and second legs are visible, and the chaetotaxies of those body parts are approximately recognizable. On the contrary, the gnathosoma is not found, and the third and fourth legs are missing. Holotype ˁ: Idiosoma length 350, width 215.

Remarks.ɹThe specimen number given on the glass slide partly corresponds to that in the original description (ˁ:1/31) of Makarova (1974). The general features of this type specimen and collecting locality shown on the slide are consistent with those given in the original description. Therefore, it is most likely that this specimen is the holotype of Copidognathus pacificus . The species name on the glass slide is given as Copidognathopsis orientalis . On the contrary, the specimen number given on the slide almost corresponds to that in the original description of C. pacificus . At that time, Copidognathopsis was regarded as one subgenus in the genus Copidognathus . Copidognathus orientalis was described by Newell (1951) based on a specimen from Attu Island in Alaska. Makarova (1974) described a new species under the name of Copidognathus (Copidognathopsis) pacificus , whereas the name of the new species was given as Copidognathus ( Copidognathopsis orientalis ) [sic] in the summary. Makarova (1874) got pacificus confused with orientalis in writing the manuscript. The sex of the specimen indicated in Fig. 5 in Makarova (1974) is not female (самка), but male (самец).
