038987F2FF9AFF952FCAB8DDFE75FED6.taxon	description	Description. Mature colony small (1.5 mm high), stolonal, monosiphonic, arising from creeping tubular stolons (Figs. 1 A – E). Bilayered exoskeleton formed by perisarc and exosarc. Perisarc continuous from hydrorhiza to tentacle base unwrinkled at the base of hydrocaulus. Exosarc thin, thinner over hydranth, tentacle base, and hypostome, forming a pseudohydrotheca (Figs. 1 D, F, H). Hydranth vasiform, merging with short pedicel. Hypostome conical, 10 – 12 tentacles in two very close whorls (Fig. 1 F). Gonophore fixed sporosac on hydrorhiza, pedicellate, ovoid, without radial canals, enveloped in the thin exoskeleton (Fig. 1 E). Nematocysts of tentacles: microbasic eurytele and desmoneme (Fig. 1 G).	en	Cruz-Gómez, Christopher, Mendoza-Becerril, María A.

038987F2FF9AFF952FCAB8DDFE75FED6.taxon	discussion	Remarks. See Calder (1988) and Schuchert (2007) for taxonomic details and synonyms of this species. There are currently five species of the genus Bimeria (WoRMS 2024). The species B. vestita is distinguished from the remainder of the genus species by the proximal part of its tentacles being ensheathed with an exoskeleton (Calder 1988; Schuchert 2007).	en	Cruz-Gómez, Christopher, Mendoza-Becerril, María A.
