194 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I4I 



Sobolev (1937) found 72 percent of Blattella germanica collected 

 in Gorkov (U.S.S.R.) infected with Blatticola hlattae. The mean 

 number of worms per host was 1.8, the maximum 5. Sondak (1935) 

 found about 30 percent of 788 B. germanica collected in Leningrad 

 to be infected with B. hlattae. Groschaft (1956) regularly found only 

 single worms in B. germanica, collected in a laboratory in Prague, 

 except for two females that contained 2 and 3 worms each. 



Blattophila sphaerolaima Cobb, 1920 



Synonymy. — Aorurus sphaerolaima (Cobb, 1920) Travassos, 1929. 

 Although Chitwood (1932) indicated that the taxonomic position of 

 this nematode is questionable, Chitwood and Chitwood, 1934, ap- 

 parently accepted it as a valid species in describing the variety javanica. 



Natural host. — Panesthia laevicollis [Cobb recorded the host as 

 Panesthia hrevicollis, but no such cockroach exists. Van Zwaluwen- 

 burg (1928) and Caudell {in Chitwood, 1932) believed that Cobb 

 meant Panesthia laevicollis. According to Gurney (personal com- 

 munication, 1957) Caudell's notes show that in 1933 he wrote to Dr. 

 Chitwood and explained that he had compared Cobb's figure of the 

 cockroach with laevicollis Saussure (figures and description) and had 

 found them the same.] Australia, New South Wales (Cobb, 1920). 



Blattophila sphaerolaima var. javanica Chitwood and Qiitwood, 1934

 wood and Chitwood, 1934).

 magalhaesi (Schwenck, 1926) Travassos, 1929 [Basir, 1956].
