Resumen:
Moniliformis ibunami n. sp., is described from the intestine of the
transvolcanic deermouse Peromyscus hylocetes Merriam 1898 (Cricetidae)
from Parque Nacional Nevado de Colima ``El Floripondio'', Jalisco,
Mexico. The new species can be distinguished morphologically from the
other 18 congeneric species of Moniliformis by a combination of
morphological and molecular characters including the number of hooks on
the proboscis (12 longitudinal rows, each one with six to eight
transversally arranged unrooted hooks), the proboscis length (230-270 mu
m), the female trunk length (159-186 mm) and egg size (40-70 x 20-40).
For molecular distinction, nearly complete sequences of the small
subunit (SSU) and large subunit (LSU) of the nuclear ribosomal DNA and
cytochrome oxidase subunit 1 (cox 1) of the mitochondrial DNA of the new
species were obtained and compared with available sequences downloaded
from GenBank. Phylogenetic analyses inferred with the three molecular
markers consistently showed that Moniliformis ibunami n. sp. is sister
to other congeneric species of Moniliformis. The genetic distance with
cox 1 gene among Moniliformis ibunami n. sp., M. saudi, M. cryptosaudi,
M. kalahariensis, M. necromysi and M. moniliformis ranged from 20 to
27%. Morphological evidence and high genetic distance, plus the
phylogenetic analyses, indicate that acanthocephalans collected from the
intestines of transvolcanic deer mice represent a new species which
constitutes the seventh species of the genus Moniliformis in the
Americas.
