Two new species of the Clubiona corticalis-group from Yunnan Province, China (Araneae, Clubionidae)

Abstract The present paper describes two new Clubiona corticalis-group species collected from Xishuangbanna, Yunnan Province of China: Clubiona submoralis sp. n. (♀♂) and Clubiona pollicaris sp. n. (♀♂).

Clubiona corticalis-group was first recognized by Simon (1932). Atalia Thorell, 1887(type species A. concinna Thorell, 1887 to the corticalis-group) and subgenus Paraclubiona Lohmander, 1944 (with type species C. corticalis) are currently considered as junior synonyms of Clubiona. Species of this group can be recognized by the following characters: inflated tegulum; long filiform, spiniform, or short embolus; simple and weakly developed retrolateral tibial apophysis; the anterior position of copulatory openings (Mikhailov 1995).
Currently, the corticalis-group includes 48 species mainly distributed in Eurasia and Australia (Mikhailov 1995, Deeleman-Reinhold 2001, Liu et al. 2007). Among these, at least 18 species have been recorded from China (see Table 1).
While examining Clubiona specimens collected from Xishuangbanna Prefecture, Yunnan Province of China, we found two new species belonging to the corticalisgroup, which are described in this paper.

Material and methods
All specimens studied are stored in 75% ethanol and deposited in the Institute of Zoology, Chinese Academy of Sciences in Beijing (IZCAS). All specimens were examined under a Tech XTL-II stereomicro scope. The photos, drawings and measurements were prepared using a Leica M205A stereomicroscope equipped with a DFC450 CCD camera and a drawing tube. Carapace length was measured from the anterior mar-
♂♀ Yunnan gin to the posterior margin of the carapace medially. The eyes were measured as the maximum diameter of the lens in dorsal or frontal view. The measurements of legs are shown as total length (femur, patella, tibia, metatarsus, tarsus). The epigyne was cleared in a solution of potassium hydroxide (KOH) and transferred to 75% ethanol for taking photos, drawing and measuring. All measurements are in millimeters.
Etymology. The species name refers to a close resemblance between the new species and C. moralis.
Epigyne (Figs 3-4, 8-9). Copulatory openings located anteriorly; in ventral view, the anterior part of copulatory ducts well visible and extending posteriorly, then connecting to bursae; spermathecae located anterior to bursae, both of them almost spherical, and with the same size as bursae.
Etymology. The species name is derived from the Latin word "pollicaris", and refers to the prolateral patellar apophysis, which in ventral view is thumb-shaped.
