摘要

Cucullanus lithodorasi n. sp. (Nematoda: Cucullanidae), 收集自Lithodoras dorsalis (Siluriformes) 的肠道和巴西北海岸的水域。该新种在泄殖腔乳突的数量和排列上不同于同类：5 对前泄殖腔乳突和 5 对后泄殖腔乳突，并且存在位于泄殖腔稍前方的非成对腹面乳突。这是巴西咸水中感染鱼类的该属的第三个标称种。

Cucullanus lithodorasi n. sp. (Nematoda: Cucullanidae), a parasite of Lithodoras dorsalis (Siluriformes: Doradidae) on the north coast of Brazil.

Cucullanus lithodorasi n. sp. (Nematoda: Cucullanidae), collected from the intestine of Lithodoras dorsalis (Siluriformes) and waters of the north coast of Brazil is described based on light and scanning electron microscopic observations. The new species differs from its congeners in the number and arrangement of cloacal papillae: five precloacal pairs and five postcloacal pairs and presence of unpaired ventral papillae located slightly anterior to the cloaca. This is the third nominal species of the genus infecting fishes from brackish water from Brazil.
