4、n Basin and varies from2831 to 28 46 N and 10617 to 10630 E 1. With the help of favorable climate and sufficientrainfall, the whole zone is decked with luxuriant forests. There are at least 1313 vascular plants 2. But animals in this zone are dispersedly known, presently 18 amphibian 3, 56 beetles20
5、(Scarabaeoidea) 4, 155 butterflies 1 and 48 longhorn beetles 5 were reported.The spiders diversity of Simian Mountain is poorly known up to now. The exploration of spiders from this area was just begun in 2011 by us. In this paper, two new species of the dark sac spider family Corinnidae are reporte
6、d. This family is one of the largest ones with more than 1000 spider worldwide. But in China, only about 60 species are recorded 6-8. This family of Chinese25fauna is far from clear.1Material and methodsSpider photos were taken by Canon EOS 7D with EF 100mm F2.8L Lens. All specimens are preserved in
7、 75% ethanol and were examined, illustrated, photographed and measured using a Leica M205C stereomicroscope equipped with a drawing tube, a Leica DFC420 Camera and LAS30software (Ver. 3.8). Male palps and female epigynes were examined and illustrated after they were dissected. Female genitalia were
8、cleared in 90% lactic acid. Eye sizes are measured as the maximum diameter from above. Leg measurements are shown as: total length (femur, patella and tibia, metatarsus, tarsus). All measurements are in millimetres. All specimens examined here are deposited in the School of Life Science, Southwest U

Wang leg.EtymologyThe specific name is taken from the type locality; noun.55Diagnosis.The new species is similar to O. komurai 9, but differs from the latter by the strong RTA, the thin and retro
15、laterally pointing embolus, the wide distal part of tegulum of male palp (Figs 2BC,3FG), the absence of median plate, the centrally located copulatory openings with short distance from each other and the thin copulatory ducts of epigyne (Figs 2DE, 3HI). This new species is60also similar to O. longit
16、uba Wang et al. 20128, but can be distinguished by the long andrelatively peaked RTA, the retrolaterally pointing embolus of male palp, the enantiomorphic copulatory openings close to each other and the different shape of spermathecae of epigyne.
