The taxonomy and systematics of European house spiders, currently constituting the ill-defined Tegenaria−Malthonica complex (including Aterigena) in the family Agelenidae, are revised. In Europe four monophyletic genera and 81 species are defined. One genus, Eratigena gen. nov., and seven species are described as new; at species level 17 new synonyms and 20 new combinations are proposed, and the original combination of 14 species is reinstated. Five species could not be placed (incertae sedis) because of insufficient material and one taxon is regarded as ‘nomen dubium’. On the basis of a detailed morphological assessment, 88 characters were chosen for a cladistic analysis. Phylogenetically informative characters include mostly spination patterns as well as spinneret and genital structures. In addition to morphology, three gene sections [cytochrome c oxidase subunit 1 (CO1), nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NADH1) 28S] were analysed. Morphological and molecular analyses were performed individually and in combination applying maximum parsimony and Bayesian tree search methods. In all resulting trees Malthonica and Tegenaria in their present composition are either polyphyletic or paraphyletic. Consequently, we redefined the two genera and erected a new genus, Eratigena gen. nov. Identification keys are provided for the European agelenid genera as well as for the European species of Tegenaria and Eratigena gen. nov. The genera and most of the constituent species are described and illustrated. The new classification has also been applied to some extra European members of the Tegenaria-Malthonica complex resulting in additional three new synonyms, seven reversals to the original combination, and four new combinations. © 2013 The Linnean Society of London

Aterigena n. gen. is erected for four Palearctic species of funnel-web spiders previously placed in Tegenaria Latreille 1804 or Malthonica Simon 1898 (Agelenidae: Tegenariini) and A. aspromontensis n. sp., an Italian species described here. The following new combinations are proposed: Aterigena Aculeata (Wang 1992), A. ligurica (Simon 1916), n. comb. (from Tegenaria), as well as A. aliquoi (Brignoli 1971) and A. soriculata (Simon 1873), n. comb. (from Malthonica). The latter two species were originally described in Tegenaria. The new genus is diagnosed by the unique combination of several morphological character states (e.g., notched trochanters III and IV, lateral spines on patellae, shape of vulvae). The monophyly of the new genus is also supported by a molecular analysis based on CO1 sequences of several taxa. Keys are provided for the identification of the recognized genera of Tegenariini and the species of Aterigena n. gen. Several species of Pseudotegenaria Caporiacco 1934, originally described in Tegenaria, are morphologically close to Tegenaria tridentina L. Koch 1872, a species that is grouped in the cladistic analysis using CO1 in the monophyletic taxon "Tegenaria clade 1". The species are therefore transferred back to Tegenaria as Tegenaria animata Kratochvil & Miller 1940 stat. rev., T. bayeri Kratochvil 1934 stat. rev., T basilica Kratochvil & Miller 1940 stat. rev. and T. decolorata Kratochvil & Miller 1940 stat. rev. Aterigena n. gen. has an interesting geographical distribution: it is widely disjunct in the Palearctic. Four species occur in the Mediterranean and one in China, respectively. A. ligurica is relatively widely distributed in mainland Italy and adjacent Southern France with a single specimen known each from Spain and Egypt (Alexandria), respectively. The latter may be the result of an accidental introduction. The other three European species are endemic to Sicily, Corsica (perhaps also Sardinia) and Calabria, respectively.
