Euglypha leclercqi

E. leclercqi, after Chardez, 1969

Euglypha leclercqi  Chardez, 1969

Diagnosis: Shell pyriform, compressed in cross-section and with an elliptical pseudostome, bordered by a double row of denticulated scales (14 to 16 per row), each of them has a fairly long median tooth surrounded on either side by a shorter tooth and more or less rounded at the top. The rest of the shell is made up of different scales, very elongated, very regular and imbricated like tiles on a roof, a type of covering found in the genus Assulina. This very particular type of imbrication is also found in other Euglypha. In this species this detail appears very well, because of the abundance of chitin, which forms a very regular pattern and shows rows of scales arranged in very regular diagonals. The outline of the shell is furnished with short and thick spines, never very numerous. At first sight this species is reminiscent of E. strigosa, but the arrangement of the oral scales with their characteristic denticulation does not allow any confusion.

Dimensions: Chardez (1969): Shell length 70—100 µm, width 35—60 µm, thickness 15—30 µm (n=4).

Habitat: Mosses.

Geographical distribution: Iceland.

Remarks: Encysted this species builds a very thick epiphragm, in the anterior third of the shell. The cyst is voluminous, more or less rounded, quite dark and delimited by a thick membrane.
