544 PROTOZOOLOGY 



Family 3 Stenophoridae Leger and Duboscq 



Development intracellular; sporadins solitary; with a simple 

 epimerite or none; cysts open by rupture; spores ovoid, with or 

 without equatorial line, not extruded in chain; in Diplopoda. 



Genus Stenophora Labbe. With or without simple epimerite; 

 spores ovoid with equatorial line, not in chain. Species (Watson, 

 1916; Pinto, 1919). 



S. larvata (Leidy) (Fig. 232, g). Sporadins up to 800m by 23m ; 

 protomerite small; in gut of Spirobolus spinigerus. 



S. robusta Ellis (Fig. 232, h). Sporadins 140-180/x by 67m; cysts and 

 spores both unobserved; in gut of Parajulus venustus, Orthomorpha 

 gracilis and 0. sp.; Colorado. 



Genus Fonsecaia Pinto. Spores elongate ovoid; without equa- 

 torial line.

 18m by 8m; in gut of Orthomorpha gracilis; Brazil. 



Family 4 Didymophyidae Leger 



Two to three sporadins in association; satellite without septum. 



Genus Didymophyes Stein. Epimerite a small pointed papilla; 

 cysts spherical, open by rupture; spores ellipsoidal. 



D. gigantea S. Sporadins slender, 1 cm. by 80- 100m; 2 deuto- 

 merites; cysts spherical, 600-700m in diameter; spores oval, 6.5m by 

 6m; in gut of larvae of Oryctes nasicornis, O. sp., and Phyllognathus 

 sp. (Leger, 1892). 



Family 5 Gregarinidae Labbe' 



Sporadins in association; epimerite simple, symmetrical; cysts 

 with or without ducts; spores symmetrical. 



Genus Gregarina Dufour. Sporadins biassociative; epimerite 

 small, globular or cylindrical; spores dolioform to cylindrical; cysts 

 open by sporoducts; in the gut of arthropods. Numerous species 

 (Watson, 1916). Morphology and physiology (Muhl, 1921). 



G. blattarum Siebold (Figs. 226; 232, k). Sporadins in syzygy, 500- 

 1100m; by 160-400m; cysts spherical or ovoidal; eight to 10 sporo- 

 ducts; spores cylindrical to dolioform, truncate at ends, 8-8. 5m by 

 3.5-4m; in the midgut of cockroaches, especially Blatta orientalis. 

 Reproduction (Schiffmann, 1919; Sprague, 1941).
