Abstract
A new species of trapdoor spider of the genus Liphistius Schiödte, 1849 (Mesothelae: Liphistiidae) is described from specimens collected from Mae Wong National Park, Klonglan district, Kamphaeng Phet province, Thailand. This Liphistius species belongs to the bristowei species-group based on the elevated cumulus and the distinct embolic part, and resembles L. yamasakii Ono, 1988. Diagnostic characters of the male and female are discussed, and a map is provided for the type localities of the 32 previously described Liphistius species in Thailand. This is the first record of a Liphistius species in the bristowei species-group that builds a T- or Y-shaped burrow with two trapdoor openings.

Liphistius maewongensis sp. nov
Etymology.— The specific epithet refers to the type locality,
Mae Wong National Park, an important tiger sanctuary in
Southeast Asia.
Remarks.— Liphistius maewongensis belongs to the bristowei
species-group sensu Schwendinger (1990), based on the
elevated cumulus (Figs. 4a–d) and the two longitudinal ridges
on the sclerotized part of the embolic parts that reach the tip
(Fig. 4e). Thus, the bristowei species-group of Liphistius is
currently comprised of L. bristowei, L. lannaianus, L. marginatus
Schwendinger, 1990, L. yamasakii, and L. maewongensis.
Despite the similarity between L. yamasakii and L. maewongensis,
the male pedipalp shapes are grossly different.
