Chilomastix cuspidata ( Larsen et Patterson, 1990) Bernard et al., 1997

Figs 1e, 2e

Description: Cells are drop-shaped with a long posterior spike and 20–32 µm long (including the spike) with a groove extending from the apex to the posterior end of the untapered part of the cell. The cells have four flagella inserting subapically and are directed anterior laterally. Rarely observed.

Remarks: This species was transferred from Percolomonas to Chilomastix cuspidata by Bernard et al. (1997). It has been found at marine sites in Australia, Demark and Ireland ( Larsen and Patterson 1990; Fenchel et al. 1995; Bernard et al. 1997, 2000; Weerakoon et al. 1999; Lee 2015) and previously reported range of cell lengths is from 14 to 33 µm.
