Apostenus sp. indet. ( figs. 16-16a )

Material: Canary Island Tenerife, Anaga Mountains, at the road to the Pico Ingles, laurisiva , 1♂ leg. 13. IX. 2001; Univ. La Laguna ( T13 <100>) .

The body length of the spider is 2.4 mm, its prosomal length is 1.15 mm, the legs are distinctly annulated, the ventral opisthosomal bristles are short and indistinct (probably partly rubbed off); ♂ -pedipalpus ( figs. 16-16a ): The tibial apophysis is wide and stands out, the structures of the bulbus are similar to A. annulipedes sensu WUNDERLICH (1992: 478, figs. 750e-h) (Tenerife, Bco. del Pino) (really annulipes ?), in which a slender tibial apophysis and a large conductor exist.

On Tenerife exist at least two or even three species of the genus Apostenus WESTRING 1851 . The locus typicus of annulipedes (female holotype) is Esperanza. One of the males - the male from the Bco. del Pino or the male which is treated in the present paper - may be conspecific with the holotype of annulipedes or not; both sexes from the same localities are needed for sure conclusions.

Distribution: Canary Islands, Tenerife.
