dc.description | The genus Omalonyx d’Orbigny, 1837, includes neotropical semi-aquatic
succineid
slugs and comprises six recognized species to date. Field surveys across continental
South America recovered five of the six recognized species. According to the morphological
characters traditionally included in Omalonyx descriptions, the specimens
were tentatively identified as O. matheroni, O. pattersonae, O. convexus, O. geayi
and O. unguis. Employing sequences of mitochondrial cytochrome oxidase I (COI)
alone or combined with the nuclear second internal transcribed spacer (ITS2) in discovery
methods of species delimitation (GMYC and STACEY) led to species delimitation
hypotheses that, except for unambiguously supporting O. convexus, have
no correspondence to morphologically based assignments. To choose the delimitation
model that best fit our data, the hypotheses recovered by GMYC, STACEY and
morphology and created by merging species recovered by those methods had their
marginal likelihood estimated and compared using the Bayes factors. The best-supported
hypothesis distinguished two species besides O. convexus: one widespread
over most of South America and the other restricted to Rio de Janeiro State, Brazil.
Furthermore, the pattern of genetic structuring supports pathways connecting the
Amazonian and Atlantic forests. This pattern is similar to that observed in terrestrial
taxa (e.g., forest-dwelling
small mammals) and is different from the pattern for fully
aquatic taxa. | |
