Morphometrics and molecular analysis of Ozolaimus linstowi n. sp. (Oxyuroidea: Pharyngodonidae) from the green lizard Iguana iguana.
Ozolaimus linstowi n. sp. is described from the large intestine of Iguana iguana Linnaeus, 1758 from Mexico. The present species can be easily distinguished from O. megatyphlon and O. cirratus by the presence of a long and slender pharynx not divided into sections, more similar to the remaining two species, O. monhystera and O. ctenosauri. Ozolaimus linstowi n. sp. can be differentiated from O. monhystera by the shorter spicule length and smaller body size of both males and females. Males of O. linstowi n. sp. are morphologically close to those of O. ctenosauri, but females possess a markedly smaller body size and differ in the organization of the oral cuticular armature. Adult males of O. linstowi n. sp. bear some characteristic features of the J3 juvenile morphology in terms of the cuticular organization of the oral and buccal capsule. Phylogenetic analysis of O. linstowi n. sp. using partial small subunit (SSU) and D2-D3 large subunit (LSU) rDNA shows relationships with several Oxyuridae genera.
