Abstract
Males and females of four mygalomorph spider species (family Halonoproctidae, subfamily Ummidiinae) are newly described from Thailand, and the taxonomy of Ummidiinae is discussed. This is the first time that trapdoor spider species in this subfamily are described from Thailand. Two of these new species belong to the genus Conothele, the other two species are placed in the genus Latouchia. Conothele martensi spec. nov. was found in the north of the country (Chiang Mai Province), C. isan spec. nov. and Latouchia incerta spec. nov. were collected in northeastern Thailand (Buri Ram Province, Surin Province and Roi Et Province), and L. maculosa spec. nov. was found in the southern coastal province of Prachuap Khiri Khan.

 A Habitat at the type locality. B Closed trapdoor (indicated by white arrow). C Burrow entrance with the trapdoor fully opened (note the dense white silk lining of the burrow walls and of the inside of the trapdoor). D Characteristic defence behaviour of many fossorial trapdoor spiders: clinging onto the inside of the trapdoor and pulling it back into the closed position against an external force. E Living female outside her burrow.
