Resumen:
Bess beetles (Passalidae) are known to maintain biological interactions
with a diverse gut symbiotic community, which is far from being well
described since these communities from most of the species of Passalidae
have not been studied. In order to improve our knowledge of these
communities, we describe a new species of Nematoda of the genus
Hystrignathus (Hystrignathidae) associated with Passalus interruptus, a
bess beetle species of the tribe Passalini collected in Hu??nuco, Peru,
in the Peruvian Amazonia. Hystrignathus nunashae n. sp. is characterized
by the presence of cuticular spines beginning just after the end of the
first cephalic annule, a posterior cephalic ring dilated and longer than
the anterior ring, as well as ornamented eggs. The new species has a
didelphic-amphidelphic reproductive system, lateral alae extending from
the posterior end of procorpus almost reaching the anus, and a short
subulate tail. The external and internal morphological traits of the new
species are described, and additionally, based on nuclear ribosomal DNA,
we investigated the phylogenetic relationships of the new species.
