Host and substrate specificity: Gruber (1884) did not mention any substrate or host. This species was found as epibiont on harpacticoid copepod (Chatterjee et al. 2020a); on nematode host belongs to the family Microlaimidae (present report). Distribution: Italy (Gruber 1884); the Black Sea (Dovgal 2013); west coast of India, Arabian Sea (Chatterjee 2020a); Arabian Sea, 2054 m depth (present report). Remarks: The species was described by Gruber (1884) as Acineta sp. from the water area of the port of Genoa (Italy) without mentioning the substrate or host and was observed in the Black Sea without mention of locality or substrate (Keppen 1888; Dovgal 2013). This species was redescribed by Curds (1985a) based on Gruber’s data as Acinetides gruberi Curds, 1985.Published as part of Chatterjee, Tapas, Sautya, Sabyasachi, Dovgal, Igor, Gaikwad, Santosh, Khokher, Sanofar H. & Choudhury, Amita, 2022, Report of deep-sea epibiont ciliates (Ciliophora) from more than 1000 m depth of the Arabian Sea, Indian Ocean, pp. 423-434 in Zootaxa 5120 (3) on page 429, DOI: 10.11646/zootaxa.5120.3.8, http://zenodo.org/record/638956
