Malawimonas O'Kelly & Nerad
(1999,
p. 529).
Malawimonads without loricas or other morphologically distinctive covering
on cell or flagellar surfaces. Flagellate cells bacterivorous, ingesting
prey near the posterior end of the ventral groove; permanently
differentiated cytostome lacking.
Etymology: "Malawi flagellate" (Malawi-, the African nation
from which the type species was isolated; monas,
Gk. "wanderer". Malawimonas is a third declension feminine Latin

Nerad
(1999,

Freshwater protists with characteristics of genus, associated with lake
sediments. Cell shape plastic, typically elongate, tapered at both ends,
ventral surface planar to concave, dorsal surface convex. Flagellate
cells 4.0 - 8.5 micrometres in length, 2.0 - 4.5 micrometres in
width. Cysts 3.5 - 4.9 micrometres diameter, spherical, with smooth wall,
attached to substrate by pad of adhesive material.
Type locality: Chirombo Bay, Lake Nyasa, Malawi (14° 5
´ S, 34° 5 ´ W).
Holotype: Cryopreserved living material, conserved at the
American
Type Culture Collection (ATCC) as strain 50310. Protargol-stained
slides
and resin-embedded cells derived from strain 50310 conserved at ATCC and
the Natural History Museum, Smithsonian Institution, accession number USNM
51468.
