Limnonectes hascheanus is a species of frog in the family Dicroglossidae. It is found in the Malay Peninsula (from southern Myanmar and Thailand to Peninsular Malaysia); its occurrence in the Andaman Islands requires confirmation.^[2] It is a small frog, males being 19–25 mm (0.75–0.98 in) and females 21–25 mm (0.83–0.98 in) snout-vent length.^[3]

Taxonomy

Taxonomic work by Robert F. Inger and Bryan L. Stuart in 2010^[3] on Limnonectes hascheanus and L. limborgi has led to better understanding of these similar species — L. limborgi has been considered a junior synonym of L. hascheanus.^[2] While the species are morphologically similar, mainly differing in body size (L. hascheanus is smaller), they are genetically distinct.^[3] This taxonomic work has also led to redefinition of ranges of both species, and the range of L. hascheanus (as presently defined) is much more restricted^[2] than what was reported in the latest (2004) IUCN assessment for this species.^[1]

Life cycle

The life cycle of Limnonectes hascheanus has earlier been reported to have direct development (no free-swimming tadpole stage, which instead hatch as tiny full-formed frogs). Notice that the original observations of this phenomenon came from outside the range of L. hascheanus and probably apply to L. limborgi.^[3] More importantly, careful observations have showed that L. limborgi has free-swimming but endotrophic larvae; this probably applies to L. hascheanus too.^[4]
