Physalopteroides arnoensis n. sp. (Nematoda: Physalopteroidea) and other intestinal helminths of the mourning gecko, Lepidodactylus lugubris (Sauria: Gekkonidae), from Arno Atoll, Republic of the Marshall Islands, Oceania.
Physalopteroides arnoensis n. sp. (Nematoda: Physalopteroidea) from the intestinal tract of the gecko Lepidodactylus lugubris is described and illustrated. Physalopteroides arnoensis is the 18th species to be assigned to the genus and is distinguished from other oriental species by the distribution pattern of caudal papillae of the male: 22 posterior subventral pedunculated papillae; 8 precloacal papillae in symmetrical pairs; 14 postcloacal papillae, 6 papillae immediately postcloacal in symmetrial pairs and remaining 8 papillae asymmetrically placed, 3 on right, 5 on left. Other helminths found include Pharyngodon lepidodactylus, Hedruris hanleyae, Maxvachonia chabaudi, and larvae of Ascarops sp. Our review of Physalopteroides removes all subspecies designations; Physalopteroides minor Caballero, 1969 n. comb is proposed.
