Rhacodactylus trachycephalus, commonly known as the lesser rough-snouted giant gecko, dwarf rough-snouted giant gecko, or tough-snouted giant gecko, is a species of gecko endemic to two small areas of islands in New Caledonia. Its body grows to around 10 centimetres (3.9 in) and has a mosaic pattern with a variety of colors. Rhacodactylus trachyrhynchus is a closely related species, but R. trachycephalus is smaller and has a number of other noticeable differences. R. trachycephalus is viviparous, giving birth to only one or two young a year. Its restricted humid forest habitat is vulnerable due to multiple threats. As a result of habitat reduction, low reproduction rate and small population, it is one of the rarest geckos in the world.
