Validation and new synonymies proposed for Cheiracanthium species from South and Southeast Asia (Araneae, Clubionidae)

Abstract

The primary types of Cheiracanthium species from South and Southeast Asia were examined. Cheiracanthium insigne O.P.-Cambridge, 1874 is considered a senior synonym of Eutittha gracilipes Thorell, 1895 (male). Eutittha truncata Thorell, 1895 (female) is not a conspecific female of E. gracilipes, provisionally threated as a separate species and proposed here as a valid taxon because it does not resemble the female of C. insigne. Cheiracanthium rupicolum (Thorell, 1897) is regarded as a senior synonym of C. gyirongense Hu & Li, 1987. The Himalaya form of C. triviale (Thorell, 1895), which was mentioned and illustrated in Gravely (1931), was misidentified and belongs to C. rupicolum. Cheiracanthium insulanum (Thorell, 1878) bears strong resemblance to that of C. melanostomum (Thorell, 1895); they probably belong to the same species. Copyright © 2012 · Magnolia Press.
