| Abstract |
Seven typhloplanoids from the Indian Ocean are discussed; six of them are new to science. We place four of the new species within the Trigonostomidae. Gandalfia bilunata gen. nov. sp. nov. is characterized by a tubiform stylet and two semilunar structures in the afferent duct. Mahurubia clava gen. nov. sp. nov. has a gutter-shaped stylet and a club-shaped mouthpiece on the bursa. Parapharyngiella involucrum gen. nov. sp. nov. is characterized by a stylet in the form of a question mark and a bursal mouthpiece with a club-shaped and a barrel-shaped part. Poseidoplanella halleti gen. nov. sp. nov. is characterized by an unpaired ovary, a funnel-shaped stylet connected with a plate, and a small, tubular bursal mouthpiece. Furthermore, new data are given on Ceratopera axi. The two other new species belong to the Typhloplanidae. Aegira annabellae gen. nov. sp. nov., a marine species, is characterized by a box-shaped stylet and a long, pseudocuticularized ejaculatory duct. Castrada trispina sp., a freshwater species, has a copulatory bursa with three spines. Mahurubia clava gen. nov. sp. nov. and Parapharyngiella involucrum gen. nov. sp. nov. occur at Zanzibar, Tanzania. The other five species have been found on Kerguelen. |
