“…1, 9, 33–37). Huttenlauch (1986, 1987) showed that the circumoral kinety is not interrupted by the adoral organelles, which matches the present data (Fig. 9, 33–37), but disagrees with previous light microcopic observations (Foissner 1984; Wilbert and Schmall 1976); obviously, the circumoral dikinetids neighbouring the adoral organelles were interpreted as belonging to the latter.…”

“…Family Colepidae. The Colepidae Ehrenberg, 1838 include ciliates with a calcified armour and a prostome ciliary organization (Corliss 1979;Foissner 1984;Foissner et al 1994Foissner et al , 1999Huttenlauch 1986Huttenlauch , 1987Huttenlauch and Bardele 1987;Kahl 1930;Small and Lynn 1985;Wilbert and Schmall 1976). Although details vary considerably, the basic organization is the same in all genera and species (Fig.…”

“…Thus, they are difficult to investigate and prone to misinterpretations. Fortunately, there are now detailed electron microscopic investigations available (Huttenlauch 1986, 1987) that give us the possibility to reinterpret earlier light microscopic descriptions. Such data show that the arrangement and structure of the adoral organelles is very similar in all colepids.…”

Levicoleps biwae n. gen., n. sp. was discovered in organic mud on the shore of Lake Biwa, Japan. Its morphology and small subunit rRNA gene sequence were studied with standard methods. Further, we established a terminology for the colepid armour and selected four features for genus recognition: the number of armour tiers, the structure of the tier plates, the presence/absence of armour spines, and the number of adoral organelles (three or five). The Japanese colepid, a barrel-shaped ciliate with an average size of 75 x 45 microm, has six armour tiers and hirtus-type tier plates, but lacks armour spines, both in the environment and in laboratory culture. Thus, it is considered to represent a new genus. This rank is supported by the considerable genetic distance (7%) from the common Coleps hirtus. Although L. biwae looks quite similar to C. hirtus in vivo, it is very likely most closely related to Coleps amphacanthus, a species with conspicuous armour spines, as indicated by body size, the number of ciliary rows and, especially, the multiple caudal cilia. Lake Biwa is about four million years old and inhabited by many endemic organisms, ranging from algae to large fish. Thus, we suspect that L. biwae is restricted to Lake Biwa or, at least, to Asia. Based on literature data and the generic features established, we also propose the new genus Reticoleps for Coleps remanei Kahl, 1933, and resurrect the genus Pinacocoleps Diesing, 1865 to include Coleps incurvus Ehrenberg, 1833, Coleps pulcher Spiegel, 1926, Coleps tessalatus Kahl, 1930 and, probably, Baikalocoleps quadratus Obolkina, 1995a. Nine colepid genera are diagnosed and dichotomously keyed.
