in gut of Cryptocercus punctulatus (Cleveland, 1951a). 



U. talea C. (Fig. 174, d). 7 5-300 /i by 15-50/t; sexual reproduction 

 (Cleveland, 1951a). 



Family 4 Staurojoeninidae Grassi 



Genus Staurojoenina Grassi. Pyriform to cylindrical; anterior 

 region conical; nucleus spherical, central; 4 flagellar tufts from ante- 

 rior end; ingest wood fragments; in termite gut (Grassi, 1917). 



S. assimilis Kirby (Fig. 174, e). 105-190/z long; in Kalotermes 

 minor (Kirby, 1926). 



Genus Idionympha Cleveland et al. Acorn-shaped; axostyles 8-18; 

 fine parabasals grouped in 4 areas; pellicle non-striated; nucleus 

 nearer anterior end than that of Staurojoenina; flagellated areas 

 smaller; in gut of Cryptocercus punctulatus. 



I. perissa C. et. al (Fig. 174,/). 169-275/* by 98-155/t. 



Family 5 Kofoidiidae Light 



Genus Kofoidia Light. Spherical; flagellar tufts composed of 8-16 

 loriculae (permanently fused bundles of flagella); without either 

 axostyle or parabasal body; between oval nucleus and bases of 

 flagellar tufts, there occurs a chromatin collar; in termite gut (Light, 

 1927). 



K. loriculata L. (Fig. 175, a, b). 60-140/z in diameter; in Kalotermes 

 simplicicornis. 



Family 6 Trichonymphidae Kent 



Genus Trichonympha Leidy (Leidyonella Frenzel; Gymnonympha 

 Dobell; ? Leidy opsis Kofoid and Swezy). Anterior portion consists 

 of nipple and bell, both of which are composed of 2 layers; a distinct 

 axial core; nucleus central; flagella located in longitudinal rows on 

 bell; xylophagous; in the intestine of termites and woodroach. Many 

 species. The species inhabiting the woodroach undergo sexual repro- 

 duction at the time of molting of the host (Cleveland, 1949a) (p. 

 185). Species (Leidy, 1877; Kirby, 1932, 1944) ; nomenclature (Cleve- 

 land, 1938; Dobell, 1939); mineral ash (MacLennan and Murer, 

 1934). 



T. campanula Kofoid and Swezy (Figs. 60; 175, c). 144-313/z by 

 57-1 44/t; wood particles are taken in by posterior region of the body 

 (Fig. 35, a); in Zootermopsis angusticollis, Z. nevadensis and Z. 

 laticeps (Kofoid and Swezy, 1919). 



T. agilis Leidy (Fig. 175, d). 55-1 15/t by 22-45/*; in Reticulitermes 

 flavipes, R. lucifugus, R. speratus, R. flaviceps, R. hesperus, R. tibialis. 

 (Leidy, 1877).
