Etymology: The name refers to ‘flexible’.
Diagnosis: Protaspa , cell 10–14 µm long, somewhat flexible and dorso-ventrally flattened with an in- distinctive ventral groove. Anterior flagellum directed to left and posterior flagellum to right trails posteriorly. Nucleus situated subapically with nuclear caps.
Description: Cells are 10–14 µm long, somewhat flexible and dorso-ventrally flattened with an indistinc- tive ventral groove. The cells vary in shape and are more flexible at the posterior part of the cell. Cell surface is warty. Two non-acronematic flagella of similar length emerge subapically and are not thickened. The anterior flagellum is directed to the left direction and the posterior flagellum to the right trails posteriorly. The nucleus is situated subapically with nuclear caps. Reserve materials are seen around the nucleus. Pseudopodia were not seen. The cells move by gliding. The cells were observed twice abundantly, but not common. Description based on records of 35 cells.
Remarks: This organism is related to Protaspa because of anteriorly located nucleus with caps. It is distinguished from other species of Protaspa by having a flexible body and because two flagella of this species point in different directions – like in Neometanema species (see Lee and Simpson 2014). This species can be characterised by its flexibility and the orientation of the flagella, which make it different from the other Protaspa species listed in Hoppenrath and Leander (2006). It is similar to P. gemmifera in having reserve materials and in cell length, but is distinguished by its flexible body and because P. gemmifera moves quickly.
