Buetschlia cirrata

sp. nov.

Buetschlia cirrata n. sp.


Description. The body is ovoid in shape and tapers gradually to the anterior end. The anterior end is truncated, and the posterior end is rounded. The cytostome is at the anterior end of the body and surrounded by long, fine cilia, forming the adoral ciliary zone. The cytoproct is at the posterior end of the body. The macronucleus and micronucleus are ovoid in shape, and the micronucleus adheres to various sides of the macronucleus. The position of the macronucleus is not constant in the body. A concretion vacuole is present in the anterior one third of the body and below the adoral ciliary zone. A contractile vacuole is present in the posterior end of the body, near the cytoproct. The entire body has unevenly distributed somatic cilia (Table 2, Figures 4a View FIGURE 4 , 5 View FIGURE 5 , 6 View FIGURE 6 ).

Habitat, type host, and locality. The hindgut of Asian elephants ( Elephas maximus ) in Gaziantep Zoo, Gaziantep, Turkey. Etymology. The name cirrata is given because of the unevenly distributed somatic cilia.

Type material. The specimens are held in the endocommensal ciliates of herbivores collection in the Department of Biology, Faculty of Sciences and Arts, Kastamonu University, Kastamonu, Turkey. Holotype and paratypes are on the slide numbered as EIC-4.

Remarks. B. cirrata n. sp. is distinguishable from other Buetschlia species by its unevenly distributed somatic cilia.

Infraciliature of B. cirrata n. sp. An adoral polybrachykinety, in which each kinety extends obliquely to the longitudinal body axis, completely encircles the cytostome. Paralabial kineties are four in number, overlie slightly obliquely the concretion vacuole just posterior to the adoral polybrachykinety. Paralabial kineties have short, modified cilia, and the number of cilia varies from two to seven. The thin pellicular fold is between paralabial kineties. The number of pellicular folds is four. Somatic kineties are unevenly distributed over the body ( Figures 4b View FIGURE 4 , 5 View FIGURE 5 , 6 View FIGURE 6 ).
