Description
Small oval to pyriform flagellates (5-15 IJm) with 4 flagella extended in 2 pairs, one flagellum recurrent or trailing (Fig . SA). The preaxostylar lamina is applied against the spherical anterior nucleus, which contains a central endosome. The large pella caps the anterior part, and the slender axostyle originating from the preaxostyle traverses the cell and protrudes at the posterior end. A thin microtubular fiber follows the adhering zone of the recurrent flagellum (Figs. 2,4a). Electron microscopy has confirmed the oxymonad characters of this genus. The flagellate phagocytizes bacteria or wood and also feeds by pinocytosis. Among the 3 0 species reported, many occur in the posterior part of the gut of xylophagous insect larvae such as Tipula or coleoptera Lygirodes, Cetonia (Travis , 1932) and in orthoptera such as roaches , M. globus of Cryptocercus (Cleveland et al., 1934) ; a list of species of insects is given in Grasse ( 1 952). Many species live in the digestive tract of vertebrates : cattle , rodents (Kirby and Honigberg, 1949, Nie, 1950), reptiles, amphibians; the list of vertebrate species is given by Kulda and Nohynkova ( 1 9 7 8) , ultrastructure in Brugerolle and Joyon (1973) and in Radek (1994). ADIDA . . nympha basal bodies/flagella are inserted close to the preaxostylar lamina (P) from which arises the crystalline axostyle (A). A bundle of non-organized microtubules or paraxostyle (Pa) develops parallel to the large axostyle. The flagella (F) are adherent to the cell body. The cell is attached to the intima of the intestine of the termite host by mean of the multifid anterior holdfast (H) containing a bundle of m icrofi bri Is . (From G. Brugerolle)
