Newly Discovered Species with Triangular Head Found in Vietnam's Cliffs.

A new species of gecko, Hemiphyllodactylus lungcuensis, has been discovered in the cliffs of northern Vietnam. The Lungcu slender gecko has a "triangular" head and a "brown sand" coloring with "irregular dark brown streaks." The new species was identified based on its body shape and DNA analysis, which found it had anywhere from about 4% to about 20% genetic divergence from other known gecko species. The researchers say further field research is required to uncover the unrealized diversity of geckos in northern Vietnam.
