Park, Mi-Hyun & Min, Gi-Sik, 2016, Morphological reports of four ciliates (Ciliophora) from coastal marine and brackish water habitats in Korea, Journal of Species Research 5 (3), pp. 514-516 : 516

4. Pleuronema salmastra Dragesco, 1986 ( Fig. 1H, I )

Diagnosis. Cell size about 83­100 × 34­68 μm in impregnated specimens; four to six preoral kineties and 47­56 somatic kineties; membranelle 1 about 25% of membranelle 2 in length; posterior part of membranelle 2 hook­like; membranelle 3 three rows.

Material examined. On November 11, 2014, at Seonnyeobawi Beach , the Yellow Sea, Korea (37°26′N, 126° 22′E) .

Voucher slides. A slide of protargol­impregnated specimens was deposited at the National Institute of Biological Resources, Korea (NIBRPR0000106617).

Remarks. Among species of the coronatum ­ type group, Pleuronema salmastra is similar to P. coronatum Kent, 1881 in most respects except the number of somatic kineties (47­56 vs. 27­43) ( Wang et al., 2008).
