Estudos sôbre nematóides Filarídeos: genótipo de Dipetalonema Diesing, 1861; valor dos gêneros Acanthocheilonema Cobbold, 1870 e Breinlia Yorke & Maplestone, 1926
The author divides the article in thee parts. In the first part he studies the literature on the genotype of Dipetalonema DIESING, 1861 - D. caudispina (MOLIN, 1858), and gives a new generic diagnosis of the Diesing's genus, based upon its type species. In the second one he studies the literature on the validity of Acanthocheilonema COBBOLD, 1870, and, comparing both generic defvinition and type-species description of Acanthocheilonema dracunculoides COBBOLD, 1870 and Dipetalonema caudispina (MOLIN, 1858), concludes that Cobbold's genus Acanthocheilonema must be, definitely, considered as a synonym of Dipetalonema DIESING, 1861. In the third part a comparative study, based on the literature, is made between generic definitions and type-species descriptions of Breinlia trichosuri (BREINL, 1913) and Dipetalonema caudipina (MOLIN, 1858), and the author concludes that Breinlia must be considered as a valid genus, distinguished from Dipetalonema, principally, by the morphology fo the longer spicule.
