“…Epistylis clampi resembles E. nigrellii Arvy, Batisse, and Lacombe 1969 by the shape of the zooid. Epistylis nigrellii , which was found on Balanus eburneus in New Jersey and New York, differs from E. clampi by having an unfolded PL and one and one‐half rather than one circuit of ciliary bands on the peristome.…”

Two epibiotic peritrichs infested the blue crab, Callinectes sapidus, from the Gulf of Mexico, Mississippi, USA. Epistylis callinectes n. sp. was isolated from the epipods of maxillipeds, bases of gill-cleaning setae, and gills, and Epistylis clampi n. sp. was isolated from the exterior surfaces of the exoskeleton. Epistylis callinectes has short, symmetrically and dichotomously branched stalks; its zooid is elongate ovoid and conspicuously longer than the individual stalk branches, measuring 40-57 (49) x 18-33 (26) microm in vivo and containing a thick, undivided peristomial lip (PL). It has a single contractile vacuole and a transverse horseshoe-shaped macronucleus. Its haplokinety (H) and polykinety (Po) complete one and one-half circuits on the peristome before entering the infundibulum. There is a distal kinetal fragment present at the distal end of both the H and Po. Epistylis callinectes has 48-70 transverse silverlines from the oral area to the trochal band (TB) and 19-26 from the TB to the scopula. Epistylis clampi has long, asymmetrically, and dichotomously branched stalks. Its zooid is elongate vase-shaped, measuring 35-64 (48) x 21-30 (27) microm in vivo and with a thick, transversely folded PL. The stalks supporting zooids are unequal in length. Its zooid has a single contractile vacuole and a transverse horseshoe-shaped macronucleus occurs in the upper half of the body. Its H and Po complete approximately one circuit around the peristome before entering the infundibulum. There is a distal kinetal fragment present at the distal end of both the H and Po. This species has 71-112 transverse silverlines from the peristome to the scopula.

Although many ciliates are free-living, more than 140 families of ciliates (Alveolata, Ciliophora) include symbiotic species of animals. Symbiosis, defined as an interaction between two species, is analyzed in this chapter to show a wide diversity of symbiotic systems in ciliates (epibiosis, commensalism, mutualism, and parasitism), providing some data about ciliate strategies showing their success as symbionts. Some species are free-living as well symbionts, facultative symbionts, and obligate symbionts. Analysis of reconstructions of ancestral state evidence that the parasitism arose numerous times and independently among the lineages of ciliates. At least three evolutionary routes can be traced: (1) transition from free-living to mutualism and parasitism, (2) transition from free-living to parasitism, and (3) regression from parasitism to free-living. The evolution of the symbiosis in ciliates demonstrates a higher diversification rate concerning free-living ciliates. The analysis of the evolution of the life cycles complexity, exploring molecular data of the phases of the ciliate cycle in their hosts is also essential. We propose new approaches for an integrative study of symbiotic ciliates.

Péritriches épizoïques dans la chambre branchiale des Balanidae (Crustacea : Cirripedia) Epistylis Nigrellii n. sp. E. horizontalis (Chatton 1930)

Abstract: La cavité branchiale de Balanus balano ides L, à New York, est très souvent parasitée par des Epistylis horizontalis Chatton (1936), de même que la cavité branchiale de B. eburneus contient des Epistylis Nigrellii n. sp. ; ces deux espèces de Péritriches épizoiques sont décrites.
