410 PROTOZOOLOGY 



Genus Joenina Grassi. More complex in structure than that of 

 Joenia; flagella inserted at anterior end in a semi-circle; parabasal 

 bodies 2 elongated curved rods; xylophagous (Grassi, 1917). 



J. pulchella G. In Porotermes adamsoni. 



Genus Joenopsis Cutler. Oval; large; a horseshoe-shaped pillar at 

 anterior end, flagella arising from it; some directed anteriorly, others 

 posteriorly; parabasal bodies long rods; a strong axostyle; xylopha- 

 gous; in the termite gut (Cutler, 1920). 



J. polytricha C. In Archotermopsis wroughtoni; 95-129/z long. 



Genus Microjoenia Grassi. Small, pyriform; anterior end flat- 

 tened; flagella arranged in longitudinal rows; axostyle; parabasal 

 body simple; in termite gut (Grassi, 1892). 



M. pyriformis Brown (Fig. 173, k). 44-52 n by 24-30/x; in Reticuli- 

 termes hageni (Brown, 1930). 



Genus Mesojoenia Grassi and Foa. Large; flagellar tuft spreads 

 over a wide area; distinct axostyle, bent at posterior end; 2 para- 

 basal bodies; in termite gut (Grassi and Foa, 1911). 



M . decipiens G. In Kalotcrmes flavicollis. 



Genus Torquenympha Brown. Small; pyriform or top-form; axo- 

 style; radially symmetrical; 8 radially arranged parabasal bodies; 

 nucleus anterior; in termite gut (Brown, 1930). 



T. octoplus B. (Fig. 173, I). 15-26/x by 9-13/z; in Reticulitermes 



Family 3 Hoplonymphidae Light 



Genus Hoplonympha Light. Slender fusiform, covered with thick, 

 rigid pellicular armor; each of the two flagellar tufts arises from a 

 plate connected with blepharoplast at anterior end; nucleus near 

 anterior extremity, more or less triangular in form; in termite gut 

 (Light, 1926). 



H. natator L. (Fig. 174, a, b). 60-120/x by 5-12/x; in Kalotermes 

 simplicicornis. 



Genus Barbulanympha Cleveland et al. Acorn-shaped: small, nar- 

 row, nuclear sleeve between centrioles; number of rows of flagella 

 greater at base; large chromatin granules; numerous (80-350) para- 

 basals; axostylar filaments 80-350; flagella 1500-13,000; different 

 species show different number of chromosomes during mitosis; in gut 

 of Cryptocercus punctulatus. Four species. 



B. ujalula C. et al. (Figs. 61; 174, c). 250-340 M by 175-275 M ; 50 

 chromosomes; flagellated area 36-41ju long; centriole 28-35^ long. 



B. laurabuda C. et al. 180-240^ by 135-170/z; 40 chromosomes; 

 flagellated area 29-33/z long; centriole 24-28^ long.
