Although original description of this species lacks any information on its internal features there is no doubt in its identity, the exterior of this species is very characteristic and it is the most common solitary ascidian on the east coasts of Kamchatka (type locality of the species). In NW Pacific Styela clavata has been mistaken several times with another species, Styela clava Herdman, 1881 (e. g. by Redikorzev, 1941). These two species have similar appearance and similar names but nothing in common in their internal features, and, contrary to the statement of Redikorzev (1941), based on erroneous identification (see remarks under S. clava in Sanamyan, 2000) their geographical ranges do not overlap. The distribution of S. clavata is probably limited by Bering Sea, east coast of Kamchatka, and extends to the south to at least to central Kuril Islands		1		In NW & These & Redikorzev & The & Bering Sea									Kamchatka		central Kuril Islands	https://treatment.plazi.org/id/CC0787BCFFD507056EDEFDA1FDB0E946#F4C63CF7FFD707056E8EFBA8FBDDEA43				MaterialCitation

Van Name (1945: 318) expressed an opinion that S. yakutatensis Ritter, 1901, another externally similar species known from Yakutat Bay, southern Alaska, and Vancouver Island may be conspecific, but kept them separate. According to him S. yakutatensis has lobed male follicles (he, however, doubted that this is a valid feature separating it from S. clavata) and probably different shape of the siphonal spines (" very short and squarely truncated "). At our opinion both features, if correctly reported, especially the shape of the spines, may be significant, so we refuse from including S. yakutatensis in the synonymy of S. clavata.		1		Van Name								Iceland	Alaska	Yakutat Bay	Pribilof Islands	https://treatment.plazi.org/id/CC0787BCFFD507056EDEFDA1FDB0E946#F4C63CF7FFD707056E8EFA89FDB0E946				MaterialCitation

Although many colonies were studied previously, the material is insufficient to decide if all of them are conspecific: the variations of the shapes of colony and the number of rows of stigmata seems to be a little too big for a single species (see Sanamyan, 1998). Shallow-water potato-like dirty yellowish brown or grey colonies, we had chance to document underwater during several recent years at Kamchatka (Sanamyan & Sanamyan, 2010), appear to be certainly conspecific with the material from Matua Island described here. On the other hand, a single available photo of this species from Commander Islands shows vivid bright red colony (see Sanamyan & Sanamyan, 2015).		1		NW Pacific.

All colonies are very small and zooids are strongly contracted and the species cannot be identified precisely. The general shape and colour of the colony on the underwater photograph (Figure 10 C) reminiscent those of Aplidium eborinum. The zooids have about 11 or 12 rows of stigmata and 9 or 10 prominent longitudinal stomach folds. They are much smaller than those of A. eborinum but this may be because they are too strongly contracted. The preserved colonies resemble the specimens from Kamchatka identified by Sanamyan (1998) as A. sagamiense (Tokioka, 1967), but zooids have more rows of stigmata. Aplidium sagamiense: Sanamyan (1998) is, most probably, wrongly identified, this species inhabits warmer waters, (originally described from Sagami Bay, Japan) and it is hard to believe it may occur in cold waters around Kamchatka and north and central groups of Kuril Islands		1										Japan	Kamchatka	Kuril Islands	Sagami Bay	https://treatment.plazi.org/id/CC0787BCFFDF070D6EDEFF2FFF23EDE5#F4C63CF7FFDF070D6E8EFEF2FF27EDE5				MaterialCitation

The species was known previously only from original description based on two specimens from Atlasova Island (which belongs to north Kuril group of islands). Sanamyan (1993), having only preserved specimens, failed to recognize the structure of the systems and a peculiar shape of the colony with long ventrally bent branchial siphons protruding from the colony surface. Current record from central Kuril Islands, where it is probably not rare, extends its known geographic range to the south. The species most probably is an endemic for Kuril Islands — during many years of investigation we saw no similar colonies in Kamchatka waters, and nothing similar is known from more southern locations. The species cannot be confused with any other Distaplia species or other colonial ascidian known from the region.		1										Iceland	Kamchatka	north Kuril	central Kuril Islands	https://treatment.plazi.org/id/CC0787BCFFDE07126EDEFB3FFD69EDCE#F4C63CF7FFC007126E8EFE2CFD69EDCE				MaterialCitation
