Shallow-water Ascidians from Matua Island (central Kuril Islands, NW Pacific), part 2 Author Sanamyan, Nadya text Zootaxa 2017 2017-10-17 4337 1 121 131 journal article 31830 10.11646/zootaxa.4337.1.6 4c39ac27-2151-40ae-86d0-c4233ece5e80 1175-5326 1014089 FBB53EC0-D112-4099-BD74-9B8556521A22 Distaplia sp. ( Figures 5B ) Material examined . Matua Island, Point Kluv, 14 m , two colonies (#408, 416). Remarks. The material is represented by two small colonies, each containing few zooids ( Figure 5B ). Similar colonies sometimes occur on Commander Islands and Kamchatka (e.g. see Sanamyan & Sanamyan, 2015 ). They most closely resemble Japan species Distaplia dubia (Oka, 1927) . At our disposal are numerous specimens of D. dubia collected in vicinity of Valdivostok. Some of these colonies look exactly as figured by Nishikawa (1990, Figure 9) and certainly belong to this species. However we are not sure if colonies from more northern localities (central Kuril Islands, Kamchatka and Commander Islands) belong to the same species. The species is "featureless" and we still have no enough material to reveal its taxonomic status.
