Or slightly shorter (in ossicles with widely spaced arms); arms ordinarily
Or slightly shorter (in ossicles with broadly spaced arms); arms normally 0.1 mm lengthy. Apophyses normally four, slightly curved inward. Ventral ossicles (Figure 6I and Figure 7C,D) normally of your identical shape as dorsal but slenderer and smaller sized in size, with arms normally 0.1 mm lengthy and apophyses slightly longer or equal in length with arms. Occasionally present flatten Peniagone-type ossicles, with 4 quick apophyses or sometime with no apophyses. Polian vesicle single. Genetic information. See Table S1. Etymology. The Seclidemstat custom synthesis species is named in honor of Tatyana Sergeyevna Saveljeva (1902982), a Soviet zoologist and expert on Holothuroidea. Distribution. The species is known only from the form locality within the southern part of the Sea of Okhotsk. Remarks. Peniagone saveljevae resembles P. dubia and P. mus in external morphology within the group on the northwest Pacific species, on the other hand it differs by the absence of tube feet inside the Tianeptine sodium salt Neuronal Signaling anteriormost third or fourth in the body and modest velum. The tube feet inside the anterior half with the body can be a popular feature in Peniagone occurring in Peniagone islandicaDiversity 2021, 13,13 ofDeichmann, P. azorica von Marenzeller, P. willemoesi (Th l), P. herouardi Gebruk, P. vedeli Hansen along with other species. This kind of morphology suggests a lot more epibenthic life style. Peniagone saveljevae also differs by the dorsal ossicles with four apophyses and curved arms up to 0.15 mm long. 3.six.

Genetic data. No genetic data is accessible for examined specimens. Distribution. Type locality is off southern Chile in the depth 2652 m (1450 fathoms), Challenger, St. 302. Other confirmed records are inside the Eastern and Central Pacific, off Australia, and Antarctic (Figures 11 and 12). The new records are in the northwest Pacific, Kuril amchatka Trench region. Depth range 1360507 m. There are also about 30 records published in GBIF.org [40] from the Eastern Pacific, off Australia and New Zealand identified by P.M. O’Loughlin, N. Davey and D. Pawson. Remarks. Peniagone vitrea at the moment has two junior synonyms: P. vitrea var. setosa Ludwig and P. setosa Ludwig. Hansen [24] has re-examined the type series of P. vitrea and discovered pronounced variation in ossicle size amongst the sorts of the synonymized species and also the specimens in the Central and East Pacific reported by Clark [39] and from Galathea St. 716. The largest ossicles were within the Galathea specimen with all the arms reaching 0.7 mm in length whereas in the form specimens the arms were 0.three.five mm lengthy. In our specimens in the northwest Pacific the arms in the dorsal ossicles (Figure 8C) attained 0.4 mm, with 2 apophyses, rather straight, longer than arms and spinous. External morphology of these specimens (Figure 8A,B) corresponded properly to that in the original description with the species. The physique was strongly elongated, velum lobe broad and brief, tube feet bordering from posterior half to a single third o.
