170 HANDBOOK OF PROTOZOOLOGY 



Small. A single vesicular nucleus near the anterior end. Para- 

 sitic in the colon of the cockroach. Cysts common. 



Lophomonas hlaUarum Stein (Figs. 2; 64, e-i). Body small, 

 pyriform, but plastic. Axostyle may project beyond the pos- 

 terior margin of the body. Active swimming movements. 

 Holozoic in the colon of the cockroach. Binary or multiple 

 fission. Body length 25 to 30 microns. Widely distributed. 



Lophomottas striata Biitschli (Fig. 64, j-l). Body elongated 

 spindle in form. Body surface with obliquely arranged needle- 

 like structures which some investigators believe to be Proto- 

 phyta (to which Grasse gave the name, Fusiformis lophomona- 

 dis). Axostyle is short, never protruding. Movement sluggish. 

 Cyst spherical with the needle-like structures. In the same habi- 

 tat as the last species. 



Genus Eulophomonas Grassi. Similar to Lophomonas, but 

 the flagella vary from 5 to 15 or a little more in number. 



Eulophomonas calotermitis Grassi. In the termite, Kalotermes 

 flavicollis. 



Family 3 Joenidae Grassi 



The flagella are confined mostly to the anterior end, but 

 some of them are directed posteriorly. A conspicuous axostyle 

 is always present. Parasites of termites. 



Genus Joenia Grassi. Body ellipsoidal. Anterior portion is 

 capable of forming pseudopodia. Flagellar tufts are in part di- 

 rected anteriorly. Body surface is covered by numerous immo- 

 bile short filamentous processes, which some authors hold to be 

 symbiotic bacteria. The spherical nucleus at the anterior end; 

 posterior to the nucleus, there is a conspicuous axostyle com- 

 posed of numerous axial filaments. A parabasal apparatus sur- 

 rounds it. Bits of wood used as food. 



Joenia annectens Grassi (Fig. 65, a). In the termite, Kalo- 

 termes flavicollis. 



Genus Joenina Grassi. The structure is more complicated 

 than that of Joenia. Flagella are inserted at the anterior end in a 

 semi-circle. Parabasal bodies are two elongated curved rods. 

 Feeding on wood fragments. 



Joenina piilchella Grassi. In the termite, Porotermes adamsoni. 



Genus Parajoenia Janicki. Body oval and medium large.
