BIOTIC ASSOCIATIONS OF COCKROACHES — ROTH & WILLIS I73 



percent of 124 B. orientalis infested. Zasukhin (1930) found 10 per- 

 cent of over 3,000 B. orientalis infested. The flagellate does not harm 

 the host and is never present in the host tissue; it should be con- 

 sidered a commensal (Kudo, 1926). 



Lophomonas striata Butschli 



Synonymy. — Lophomonas sulcata Schuster is most probably identi- 

 cal with L. striata (Kudo, 1926b), 



Natural hosts. — Blatta orientalis, Germany (Butschli, 1878; 

 Schubotz, 1905) ; Europe (Janicki, 1908, 1910) ; U.S.A. (Kudo, 

 1922, 1926, 1926b; McAdow, 1931) ; U.S.S.R. (Yakimov and 

 Miller, 1922; Zasukhin, 1930); Poland (Lorenc, 1939). 



Blattella germanica, U.S.A., Ohio (McAdow, 1931). 



Blattella germanica and/or Periplaneta americana, South Africa 

 (Porter, 1930). 



Periplaneta americana, Indochina (Weill, 1929) ; Philippine Is- 

 lands (Hegner and Chu, 1930); U.S.A. (Kudo, 1926b; McAdow, 

 1 931; Armer, 1944). 



Cockroach, Venezuela (Tejera, 1926) ; England or U.S.A.? 

 (Lucas, 1928). 



"Kiichenschaben," Austria (Belar, 1916). 



Found in the host's colon, particularly the anterior portion. L. 

 striata (fig. 2, D) was found in 29 percent of 1,400 B. orientalis and 

 in 2 of 30 P. americana (Kudo, 1926, 1926b), Yakimov and Miller 

 (1922) found the organism in 9.6 percent of 124 specimens of B. 

 orientalis. Zasukhin (1930) found 8.6 percent of over 3,000 B. 

 orientalis infested. 



Grasse (1926, 1926a) identified corrugations on the surface of L. 

 striata as a bacterial parasite which he named Fttsiformis lopho- 

 monadis. 



Prolophomonas tocopola Cleveland et al. 



Natural host. — Cryptoccrcns punctulatus, California, Oregon, Vir- 

 ginia, West Virginia (Cleveland et al., 1934) : Not abundant. 



Family HOPLONYMPHIDAE 

 Barbulanympha estaboga Cleveland et al. 



Natural host. — Cryptocercus punctulatus, U.S.A., Appalachian and 

 Pacific coast areas (Cleveland et al., 1934). 



Barbulanympha coahoma (Cleveland et al., 1934) represents the 

 diploid form of B. estaboga (Cleveland, 1953).
