Zosterodasys sp. – Aliev 1990: 23, fig. 5 II.
Zosterodasys transversa – Foissner et al. 1994: 418, figs 1–29.
Zosterodasys transverses – Gong et al. 2009: 341 [18S rRNA gene sequence of a South Korean population; incorrect subsequent spelling and therefore unavailable according to the Articles 33.3 and 33.5 of the ICZN (1999)]; Wang et al. 2012: 50 View Cited Treatment , figs 5–10, 19–26 (morphological description of the South Korean population; very likely a misidentification).
Zosterodasys transversus – Jankowski 2007: 729 (without figure; mandatorily change of species group-name to masculine gen- der); Vďačný & Tirjaková 2012 (neotypification).
Diagnosis (neotype population). Size about 120–240 × 50–115 µm in vivo. Body shape broadly to narrowly obovate or elliptical with left margin anteriorly slightly projecting. Macronucleus roundish to very narrowly ellipsoidal with a single globular micronucleus. Several scattered contractile vacuoles. On average 82 ciliary rows: 36–52 ventral and 30–43 dorsal. Synhymenium incompletely encircles cell. On average 14 (12–16) nematodesmal rods. Freshwater.
Type locality. Fine organic mud and decaying tree leaves from the River Ipeľ near the village of Chľaba, Slovakia (E18°49' N47°49').
Type material. Four neotype slides with many protargol-impregnated specimens were deposited in the Biology Center of the Museum of Natural History of Upper Austria, Linz (LI).
Etymology. Not given in the original description. The Latin adjective transvers · us, - a, - um ([m, f, n]; transverse, oblique) obviously refers to the course of the synhymenium that transversely extends across the ventral side of the cell.
Remarks. For taxonomic revision and all figures, see Vďaċný & Tirjaková (2012). Wang et al. (2012) have recently redescribed “ Z. transverses ” from a South Korean population. However, “ Z. transverses ” differs from Z. transversus sensu Foissner et al. (1994) and Vďaċný & Tirjaková (2012) by marine (vs. freshwater) habitat and a much larger body (160–400 µm vs. 120–250 μm in length). On the other hand, the South Korean population matches very well the poorly known Z. numerosus by body shape and size, the contractile vacuole and nuclear pattern as well as by the marine habitat (see below).
