A new genus of the spider subfamily
Chen L, Zhao Z, Li S (2016)
Coelotine spiders are common in the Northern Hemisphere. So far, a total of 662 valid species belonging to 25 genera (
The genus
In this paper, a new genus of coelotine spiders,
Specimens were examined with a LEICA M205C stereomicroscope. Images were captured with an Olympus C7070 wide zoom digital camera (7.1 megapixels) mounted on an Olympus SZX12 dissecting microscope. Epigynes and male palps were examined after dissection from the spiders’ bodies. Epigyne was cleared by boiling it in 10% KOH solution before take photos of the vulva.
All measurements were obtained using a LEICA M205C stereomicroscope and are given in millimeters. Leg measurements are shown as: Total length (femur, patella + tibia, metatarsus, tarsus). Only structures (palp and legs) of the left body side were described and measured. The terminology used in the text and the figure legends follows = epigynal atrium = anterior lateral eye = anterior median eye = distance between AME and ALE = distance between AME and AME = distance between ALE and PLE = conductor = copulatory duct = dorsal conductor apophysis = cymbial furrow = embolus = embolic base = epigynal teeth = fertilization duct = retrolateral tibial apophysis = median apophysis = patellar apophysis = posterior lateral eye = posterior median eye = distance between PME and PLE = distance between PME and PME = retro-ventral tibial apophysis = spermatheca = anterior part of spermatheca = spermathecal head = posterior part of spermatheca = subtegulum = tegulum

Small to medium-sized, with a total length of 5–14 mm, the body brown to dark brown. Carapace narrowed in ocular area, sparsely covered with black setae, and thoracic region with longitudinal fovea and radial groove; sternum usually heart-shaped. Abdomen brown to dark brown, heavily covered with short setae; dorsum with many black irregular patches and five grey chevron-like markings, the antero-median part with one cardiac pattern, and posterior part with dark maculation. Chelicerae with 3 promarginal and 3 or 4 retromarginal teeth. Male palp with one patellar apophysis and two tibial apophyses (
In addition to morphological study, we analyzed the relationships of coelotine spiders based on molecular data (8 genes, ~ 6.5 kb) on 18 genera and 286 coelotine species. The molecular analyses (in progress) support
