BIOTIC ASSOCIATIONS OF COCKROACHES — ROTH & WILLIS I77 



Natural hosts. — Blatta orientalis, France (Debaisieux, 1927). 



Blattella germanica, France (Leger, 1909; Debaisieux, 1927). 



The organism inhabits the malpighian tubules of cockroaches. 

 Leger and Debaisieux concluded that their organism was a myceto- 

 zoan, but they may have erred in synonymizing Plistophora peri- 

 planetae with the organism they studied. Debaisieux found intracel- 

 lular stages of Peltomyces periplanetae that have not been found in 

 Plistophora periplanetae or Coelosporidium periplanetae. 



Order AMOEBINA 

 Family AMOEBIDAE 

 Hartmannella blattae Ivanic 

 Natural host. — Blatta orientalis, Yugoslavia (Ivanic, 1937) : Found 

 in the hind gut. 



Family ENDAMOEBIDAE 



In the following classification we have accepted the conclusions of 

 Kirby (1945), Kudo (1954), and others that species of Endamoeba 

 are generically different from species of Entamoeba and that the latter 

 genus is not a homonym of Endamoeba. 



Dobellina sp. 

 Natural vectors. — Blattella germanica and/or Periplaneta ameri- 

 cana, Egypt (DeCoursey and Otto, 1956, 1957) : Thirty out of 261 

 cockroaches examined contained this protozoan. 



Endamoeba blattae (Butschli) 



Synonymy. — Amoeba blattae, Entamoeba blattae, Entamoeba blat- 

 tarum.

 botz, 1905; Chen, 1933) ; U.S.A. (Leidy, 1879a, 1880; Kudo, 1922,

Blattella germanica and/or Periplaneta americana. South Africa 

 (Porter, 1930) ; Egypt (DeCoursey and Otto, 1956, 1957) : Seven 

 out of 217 cockroaches examined harbored the protozoan. 



Periplaneta americana, Philippine Islands (Hegner and Chu, 

 1930) ; U.S.A. (Morris, 1936; Armer, 1944) ; Gold Coast Colony
