Idiosoma (A), genitoanal region (B), body (C), gnathosoma (D), first leg (E). Scale bars for AC=100 µ m, BDE=50 µ m. Type series .ɹHolotype: ˂ NSMT-Ac 14693 (1/8087) and paratype : 1 ˂ NSMT-Ac 14694 (2/8087). Condition. ɹThe glass slide is partly broken and missing. Each body part is visible in both type specimens. However, the chaetotaxies of idiosoma, gnathosoma, palps, and legs are only partly recognizable. Holotype ˂: Idiosoma length 540, width 350; gnathosoma length 160, width 145. Paratype ˂: Idiosoma length 475, width 320; gnathosoma length 160, width 145. Remarks .ɹThe specimen number given on the glass slide corresponds completely to that in the original description of Makarova (1978) . The species was described by Makarova (1978) based on the specimen from the Gulf of Anadyr on the Bering Sea. Bartsch (2006 , 2009 ) mentioned that this species might be synonymous with Acanthopalpus spinosus ( Bartsch, 1978 ) as per Article 23 in the International Code of Zoological Nomenclature.
