Araneae Linyphiidae


The erigonine linyphiid genus Disembolus currently contains 24 described species (World Spider Catalog 2018). Disembolus was erected by Chamberlin and Ivie (1933) to accommodate their new species D. stridulans Chamberlin and Ivie from Utah. Since then, 23 species have been added to the genus. Chamberlin (1949) described D. zygethus Chamberlin, but the majority of species were added to the genus by Millidge (1981). Millidge (1981) described 16 species from museum specimens at the American Museum of Natural History and transferred five species from the genera Tapinocyba and Soudinus (D. alpha (Chamberlin 1949), D. kesimbus (Chamberlin 1949), D. phanus (Chamberlin 1949), D. sacerdotalis (Crosby & Bishop 1933), and D. corneliae (Chamberlin & Ivie 1944)). The last species added to the genus was D. bairdi Edwards described by Edwards in 1999. Disembolus corneliae Chamberlin and Ivie was described from the female only by Chamberlin and Ivie (1944) as Soudinus corneliae. The species was then transferred to Disembolus by Millidge (1981). Herein, I describe the male of the species for the first time.
