A Speleomantes ambrosii population living in an artificial tunnel in NW Italy was studied for two consecutive years. Activity on the walls varied cyclically in relation to seasonal temperatures and food abundance. The main food item was the trogloxenic dipteran Limonia nubeculosa, which accounted for more than 80% of the total ingested prey by volume. Juvenile cave salamanders had a broader trophic nich than adults. Oviposition and juvenile recruitment appeared to be seasonal. The spatial distribution inside the tunnel was related to microhabitat heterogeneity and particularly to the distance from the entrance. Juveniles were observed outside or close to the entrance more often than adults. Movement of adult salamanders were generally low and averaged 7 cm/day; some repeatedly recaptured individuals had a mean home range of 6 m2.

The female holotype of Clubiona distincta Thorell, 1887 from Myanmar is illustrated for the first time. It is considered ajunior synonym of C. filicata Pickard-Cambridge, 1874 originally described from India. Two new species belonging tothe genus Clubiona are described from Thailand. These taxa are C. digitata sp. nov., and C. aberrans sp. nov. The con-specific female of C. filifera Dankittipakul, 2008 is designated and described. Clubiona melanothele Thorell, 1895 and C. corrugata Bösenberg & Strand, 1906 are recorded from Thailand for the first time.

A neotype is designated for Sphingius thecatus Thorell, 1890, the type species of the genus from type locality of Penang Island, Malaysia; its conspecific female is described for the first time. Detailed morphological descriptions and illustrations for both sexes are provided. Six new species are described from Southeast Asia: S. rama sp. nov. and S. prolixus sp. nov. from eastern Thailand; S. elongatus sp. nov. from southern Thailand; S. superbus sp. nov. and S. bifurcatus sp. nov. from Thailand and Malaysia; S. spinosus sp. nov. from Thailand, Malaysia and Indonesia. Sphingius pingtung Tso et al., 2005 known from Taiwan, China is considered a junior synonym of S. scrobiculatus Thorell, 1897. Sphingius sinensis (Schenkel, 1963), originally placed in Scotophaeoides (Gnaphosidae), is regarded as a junior synonym of S. gracilis (Thorell, 1895). Additional specimens of S. gothicus Deeleman-Reinhold, 2001 were collected from northeastern and central Thailand, expanding species distribution range towards the south. Specimens of S. punctatus Deeleman-Reinhold, 2001 were collected from Thailand and Indonesia. Sphingius vivax (Thorell, 1897) and S. scrobiculatus Thorell, 1897 are recorded from Thailand for the first time.
