The monocled cobra <jats:italic>Naja kaouthia<\/jats:italic> was discovered to be a new host for this parasite in central Thailand. A comprehensive description extending the morphological and molecular characteristics of the parasites is provided to aid species recognition in future studies. The morphometric characters of 41 parasites collected from 5 cobra specimens are compared with those described in the original studies. Phylogenetic analyses using mitochondrial cytochrome c oxidase subunit 1 and nuclear 18S ribosomal RNA genes were performed to provide novel information on the systematics of <jats:italic>P. najae<\/jats:italic>. Similar characteristics were observed in the examined nematode samples, despite being found in different hosts, confirming their identity as <jats:italic>P. najae<\/jats:italic>. The molecular genetic results support the species status of <jats:italic>P. najae<\/jats:italic>, indicating <jats:italic>P. najae<\/jats:italic> is well defined and separated from other related nematode species in the family Capillariidae. Morphological descriptions, genetic sequences, evolutionary relationships among capillariids and new host and distribution records of <jats:italic>P. najae<\/jats:italic> are discussed. <jats:italic>Paracapillaria najae<\/jats:italic> specimens found in the Thai cobra had some morphological variation, and sexual size dimorphism was also indicated. <jats:italic>Paracapillaria najae<\/jats:italic> was found to infect various cobra host species and appeared to be common throughout the Oriental regions, consistent with its hosts'
