Abstract:
Descriptions, key to males and distribution are given for 49 species of Blatella which are placed in 6 species-groups. The groups are principally based on male tergal glands on tergite 7 or 7 and 8, subgenital plate and styles, paraprocts and genital phallomeres L3 and L2. Seventeen new species are described. There are 23 species of Blatella from Asia and Pacific islands and 26 from Africa. A large number of synonyms and new combinations, principally in the genera Symploce and Episymploce are presented.
