The Mastigophora 195 



length of the flagella. The parabasal apparatus consists of a number of 

 parabasal cords, usually encircling the nucleus and attached by filaments 

 to the parabasal lamella at the base of the rostrum (71, 144). Differences 

 in form, size, and number of the cords are useful taxonomic features. In 

 the rostrum, the conical anterior end of the body (Fig. 4. 52, C, D), the 

 blepharoplasts and the parabasal lamella, internal to them, form a rostral 

 "tube." This tube is sometimes widened posteriorly into a cone, as in 

 Eucomonympha (Fig. 4. 52, C). 



The family contains Deltotrichonympha Sutherland (72, 266), Eucomonympha Cleve- 

 land (39; Fig. 4. 52, C), Mixotricha Sutherland (266), Pseudotrichonympha Grassi 

 (39, 160), and Trichonympha Leidy (39, 138. 144; Fig. 4. 52, D). Trichonympha is 

 represented in termites (three families) and in the wood roach (39). Eucomonympha 

 has been reported from the wood roach; the other genera, from single families of 

 termites. 



Family 5. Teratonymphldoe. This family was erected for Teratonytnplm 

 Koidzumi (Cyclonympha Dogiel) from termites. The rostrum is similar 

 to that of Trichonymphidae, but the post-rostral flagella arise from cir- 

 cular bands underlying grooves which give the body a segmented appear- 

 ance (40, 160; Fig. 4. 52, A, B).
