| Abstract | We wish to report the occurrence of adult nematodes Ophidascaris arndti (Ascarididae) naturally infecting a new
definitive host, the Fonseca’s lancehead Bothrops fonsecai (Viperidae), and third-stage larvae of O. arndti parasitizing
a new intermediate host, the montane grass mouse Akodon montensis (Cricetidae), both found in the
Atlantic Forest of the state of Rio de Janeiro, Brazil. We elucidated the morphological characteristics of both
adults and larvae using light and scanning electron microscopy (SEM). Taxonomic affinities between larvae and
adult worms were assessed using MT-CO1 gene sequences. Adult and larval gene sequences formed a wellsupported
clade and had low pairwise p-distances, suggesting that they are conspecific. Our phylogenies also
supported the ‘arndti’, ‘filaria’, and ‘obconica’ groups as independent lineages and confirmed the allocation of
Ophidascaris within the family Ascarididae, although as an early offshoot. This is the first report of natural
infection of this helminth’s larvae in a wild intermediate host. | en_US |
