Abstract
Damarchus pylorus sp. nov., D. lanna sp. nov. and D. dao sp. nov. are described from males and females collected in western and northern Thailand. Damarchus pylorus sp. nov. and D. lanna sp. nov. are morphologically unique within the genus by males having a para-embolic apophysis and a keel composed of coarse laminae on the lower (posterior) side of the palpal organ, and by females having sperm receptacles, composed of a strongly sclerotized base and an unsclerotized head, situated on the ventral side of a relatively long genital atrium. The distantly related D. dao sp. nov. is distinguished from all other congeners by males having a tibia I coupling spur with three megaspines. Presumed relationships of these three species and of the genus Damarchus are discussed. Information on biology and burrow structures of the new species is provided. Damarchus pylorus sp. nov. stands out by plugging the side shaft of its burrow with a soil pellet; similar plugging devices in unbranched burrows are known from other spider families.
从泰国西部和北部采集的雄性和雌性中描述了Damarchus pylorus sp.nov.、D. lanna sp.nov.和D. dao sp.nov.。和 D. lanna sp.nov.在形态上在该属中是独特的，雄性有一个副结节的骨干，在掌器的下部（后部）有一个由粗糙片层组成的龙骨，雌性有精子受体，由一个强硬化的基部和一个未硬化的头部组成，位于一个相对较长的生殖器室的腹侧。D. dao sp. nov.与所有其他同属种的区别在于雄性胫骨 I 的耦合距有三个巨棘。本文讨论了这三个物种与达玛古属的假定关系。还提供了新种的生物学和洞穴结构信息。Damarchus pylorus sp. nov.的突出特点是用土壤颗粒堵塞洞穴的侧轴；其他蜘蛛科也有类似的堵塞不分枝洞穴的装置。
期刊介绍：
Men and Masculinities presents peer-reviewed empirical and theoretical scholarship grounded in the most current theoretical perspectives within gender studies, including feminism, queer theory and multiculturalism. Using diverse methodologies, Men and Masculinities"s articles explore the evolving roles and perceptions of men across society. Complementing existing publications on women"s studies and gay and lesbian studies, Men and Masculinities helps complete the spectrum of research on gender. The journal gives scholars interested in gender vital, balanced information on the burgeoning - and often misunderstood - field of masculinities studies.
