''Paroedura karstophila'' is a species of
lizard
Lizard is the common name used for all Squamata, squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most Island#Oceanic isla ...

Gekkonidae
Gekkonidae (the common geckos) is the largest family of geckos, containing over 950 described species in 62 genera. The Gekkonidae contain many of the most widespread gecko species, including house geckos (''Hemidactylus''), the tokay gecko (''Ge ...
. It is described from Montagne des Français, a karstic limestone
massif in the far north of Madagascar recently established as nature reserve. The new
species has the nostril in contact with the rostral scale and shares many characters with
P. karstophila and especially with P. homalorhina which are also restricted to karstic
habitats. Paroedura hordiesi differs from P. karstophila by a smoother skin on dorsum
and legs, by original and regenerated tails being both entirely smooth, by colouration,
and by larger snout-vent length. Morphologically the new species is most similar to P.
homalorhina from the Ankarana reserve from which it can be distinguished by shorter
limbs and a less slender habitus. Published molecular data place the new species as close
relative of P. homalorhina and another undescribed species from Nosy Hara Island, while
newly determined data of the cox1 gene for P. karstophila confirm the distinctness of
the new species from this taxon. Integrating the information from published and novel
molecular data, the new species differs from all nominal Paroedura (except P. vahiny for
which no molecular data are available to date) by strong genetic divergences. P. hordiesi
might be another microendemic species of the Montagne des Français region. We suggest
its IUCN Red List classification as "Critically Endangered" on the basis that it has an
extent of occurrence of at most 50 km², it is known from a single location, and there is a
continuing decline in the extent and quality of its habitat. It is endemic to
