Description
Retortamonas ( syn= Embadomonas , Plagiomonas, Waskia) are small pyriform or fusiform flagellates with only 2 flagella . The recurrent flagellum is associated with the cytostomal pocket but extends posteriorly (Fig . 2) . Electron microscopy has shown that 1 basal body in each pair has no flagellum (barren basal body) and a striated fiber connecting the nucleus to 1 pair of basal bodies . They form ovoid cysts. Among the 18 species described , several live in the lower gut of insect larvae of Trichoptera , Coleoptera , Diptera , such as R. alexeieffi, R. agilis (Mackinnon 1916) from the crane fly larvae Tipu/a, Orthoptera such as R. gryllotalpae from the mole cricket (Wenrich , 1932) , also in water bugs , roaches, termites; list of invertebrate species in Grasse (1952). Other species live in intestine of vertebrates such as R . intestinalis from humans and monkeys (Wenyon , RETORTAMONAD 1926), R. caviae from the guinea pig caecum (Nie, 1950), R. mitrula from Marmotta (Kirby and Honigberg, 1950).

Retortamonas ( syn= Embadomonas , Plagiomonas,
Waskia) are small pyriform or fusiform flagellates
with only 2 flagella . The recurrent flagellum is
associated with the cytostomal pocket but extends
posteriorly (Fig . 2) . Electron microscopy has
shown that 1 basal body in each pair has no
flagellum (barren basal body) and a striated fiber
connecting the nucleus to 1 pair of basal bodies .
They form ovoid cysts. Among the 18 species
described , several live in the lower gut of insect
larvae of Trichoptera , Coleoptera , Diptera , such as
R. alexeieffi, R. agilis (Mackinnon 1916) from the
crane fly larvae Tipu/a, Orthoptera such as R.
gryllotalpae from the mole cricket (Wenrich ,
1932) , also in water bugs , roaches, termites; list
