At present, the
While studying the Agelindae from the Jinggang Mountain National Nature Reserve, Jiangxi Province, we found two new species belonging to
Specimens were examined using a Zeiss Stereo Discovery V12 stereomicroscope with a Zoom Microscope System. Both the male palps and female copulatory organs were detached and examined in 75−80% ethanol under a Zeiss Axio Scope A1 compound microscope with a KUY NICE CCD. For SEM photographs, the specimens were dried on filter paper and photographed with the ZEISS EVO LS15 scanning electron microscopes under a low vacuum. The specimens were subsequently stored in 75% ethanol after SEM.
All measurements were made by using ImageView CM2000 software and in millimetres. Leg measurements are given as total length (femur, patella, tibia, metatarsus, tarsus). All the specimens are deposited in the Animal Specimen Museum, Life Science of College, Jinggangshan University (
Terminology of the male and female copulatory organs follows
Males of this genus can be easily distinguished from these of other genera of
The genus is known from subtropics in south China (Sichuan, Anhui, Guizhou, and Jiangxi provinces). Habitats of these spiders are not very diverse, usually found in woody debris, among tree roots on the ground, in humus, and under stones or tree bark.
