This research aimed at the morphological and molecular characterization of specimens collected in Thailand to extend the available information on webspinners (Embioptera). The purpose of this article is to describe Diastolembia thailandensis n. gen., n. sp. (Embiidae) from Tak and Chiang Mai provinces. Alate males of this new species are distinguished by having a large lobe of basal segment of left cercus, expansion as angular and echinulate at the apex. Hind basitarsus is short with a single papilla. Meanwhile, apterous females are without distinctive characters. This discovery brings a total of 89 species under 24 genera worldwide for this insect family. Additionally, part of the mtDNA-COI gene of a peculiar new taxon and other Thai webspinner species was reconstructed for a phylogenetic position using the Maximum Likelihood method.


Keywords: Diastolembia thailandensis, Embiidae, Embioptera, new genus and species, Thailand.
