TI - A New Soil Ciliate, Birojimia soyaensis nov. spec. (Ciliophora: Urostylida) from South Korea
AB - A new soil urostylid ciliate, Birojimia soyaensis nov. spec. was discovered from Soya Island, Incheon, South Korea. The species is described based on live and stained specimen observations, and 18S ribosomal RNA gene sequence analysis. Birojimia soyaensis nov. spec. is characterized by the following features: body slender, elongate, and somewhat twisted; body size in vivo 170–200 μm × 40–50 μm; contractile vacuole located at middle of left cell margin; cortical granules present; 37–48 adoral membranelles; 3 frontal and 2 frontoterminal cirri present; III/2 and buccal cirrus present; midventral pairs only; pretransverse ventral and transverse cirri present; 1 left and 4 right marginal rows, including 3 compound rows; 5 long dorsal kineties with 3 additional shortened kineties in anteriorly compound rows; 8–11 caudal cirri; 53–69 macronuclear nodules; and 2 or 3 micronuclei. Birojimia soyaensis nov. spec. is distinguished from B. terricola by cortical granule size (0.4–1.2 μm in diameter vs. 2–3 μm × 1–2 μm), cortical granule shape (mostly spherical vs. broadly ellipsoid to lenticular, respectively); number of caudal cirri (8–11 vs. 2–7), and number of dorsal bristle rows (8 vs. 6–7). Phylogenetic analysis suggests this new species is most closely related to the genus Hemicycliostyla.
