Drepanomonas

Drepanomonas Fresenius, 1858 (ref. ID; 2013)

From Dr. Inaki

Class Kinetofragminophora: Subclass Hypostomata: Order Nassulida: Suborder Microthoracina (ref. ID; 2013)

Synonym Drepanoceras Stein (ref. ID; 1618)

[ref. ID; 1601]
Oral apparatus ventrally between middle and posterior third of body, body more or less oblong. (ref. ID; 1601)

[ref. ID; 2013]
Outline shape sometimes oval, sometimes like a segment of an orange with both anterior and posterior ends pointed. Flattened with rigid ribbed armour, some species with spines. Somatic ciliature reduced with fewer on dorsal surface than on ventral surface. Opening to cytostome is in a depression in the left side, located in center of the body. There is sometimes a pharyngeal basket of trichites and a membranelle on the anterior left of the oral aperture. There is a centrally placed macronucleus and 2 central contractile vacuoles.
