Types

Holotype. Italy: Lazio: Frosinone, Esperia , Grotta dei Serini , ♂ ( MCSN, 543 ), 13.xii.1970, Sbordoni

Paratype. Same data as for holotype, 1 ♀ ( MCSN, 543) ; same location as holotype, 1 ♀ ( MCSN, 543), 17.v.1970, Sbordoni ; same locality as holotype, 1 ♀ ( MCSN, 543), 17.i.1971, Circolo Speleologico Romano .

Diagnosis

Tegenaria sbordonii belongs to a species group together with Teg. circeoensis sp. nov., Teg. capolongoi , and Teg. parmenidis . The most useful characters for separating these species are the shape of the RTA, the bifid terminal end of the conductor, the presence/ absence of pockets on the median plate of the epigyne, and the location of the copulatory openings.

Description

A description, including measurements, was provided by Brignoli (1971a). Some additional information is provided here.

Other important characters: Cheliceral promargin with three, retromargin with four teeth. Colulus developed as trapezoidal plate with the distal margin medially notched. Same pattern of distal spigots on PMS (in females) as described for the type species. PLS with distal segment as long as basal segment. Trichobothria on cymbium and palp tarsus absent.

Distribution

Reported from Italy (Lazio).

Discussion

Fieldwork in the region of Esperia conducted by A. Bolzern and R. Mühlethaler in May and June 2007 did not provide any specimens of Teg. sbordonii . The ‘Grotta dei Serini’ was not inspected, and it is possible that the species is restricted to caves.
