Four new species of Mononchida (Nematoda) from tropical regions

Abstract

Four new nematode species of the order Mononchida are described from the tropics. Mononchus syrmatus sp. n. from Ecuador is simply distinguished by the unusually long and slender tail. Cobbonchus aequatorialis sp. n. from Ecuador is especially characterized by the digitiform tail. Iotonchus nepotum sp. n. from Papua New Guinea is differentiated by the small body and very short, digitiform tail. Miconchus papillifer sp. n. from Ecuador differs from the other prodelphic species by the shape and length of the tail and the number and arrangement of the advulval papillae.
