First record of the genus (Mantodea, Haaniidae, Arriini) from Thailand, with the description of a new species of moss-dwelling praying mantis.

Unnahachote & Shcherbakov, is described based on a male from central Thailand. This is the first record of Stål, 1877 from the country. The new species is closely allied to (Ge & Shen, 2008) from China, differing by the absence of prozonal tubercles, the elongated pronotum, nine tibial anteroventral spines, and the truncated hindwings.
