A New Species of Wishbone Spider Genus Damarchus from Doi Inthanon National Park, Thailand (Mygalomorphae: Bemmeridae)
Abstract
The wishbone spider genus Damarchus, belonging to the family Bemmeridae, encompasses four recognized genera: Atmeto-chilus, Damarchus, Homostola, and Spiroctenus. Current distribution records indicate that Atmetochilus and Damarchus are exclusively found in Asia. To date, ten species of Damarchus have been documented, with three species reported in Thailand. However, our field surveys conducted since 2015 have identified multiple undescribed species within the genus that remain unclassified. Through detailed morphological analyses, we describe a new species, Damarchus sirindhornae Kunsete & Warrit, sp. nov., discovered in Doi Inthanon National Park. This species is classified within the workmani-group but can be distinguished from other members of the group by the absence of spines on the male coupling spur and the absence of secondary receptacles on the female spermathecae.
