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

During a large survey of agelenid spiders from different private and museum collections, a closer examination of material from all over Italy (including type material and fresh material) previously identified as Histopona italica Brignoli 1977, disclosed two new species for science, both belonging to the italica group. Based on the results of the present work, we describe Histopona leonardoi sp. n. and H. fioni sp. n. and revise the distribution pattern of H. italica group in Italy and Switzerland. Drawings and photographs of relevant structures and a table summary of the diagnostic characters allowing a fast separation of the species are provided.

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.

During a survey of the spider fauna of the Mercantour National Park in the French Alps, several interesting and new taxa were found. One of these new taxa. Tegenaria mercantarensis n. sp. (Agelenidae) is described here. The new species shows distinct morphological characters which allow easy separation from all other Tegenaria or Malthonica species. The most important characters in males are the short, truncated embolus (a character shared with T. rlomestica, the type species of Tegenaria, and T. miritica), the broad. curved hammerhead-shaped conductor and the RTA. Distinct characters in females are the atrium with wide spiral copulatory openings anterior to an anchor-shaped sclerotised ground plate, the strongly sclerotised and irregularly formed "shield" around the tubular-shaped spermathecae. and the conspicuous anterolateral lentiform areas of the spermathecae, covered only by membrane.During a survey of the spider fauna of the Mercantour National Park in the French Alps, several interesting and new taxa were found.

AB - The genera complex Tegenaria/Malthonica is a problematic spider group of the family Agelenidae. Besides taxonomical problems, new European species are described on a regular basis. Here two species from Portugal, Tegenaria barrientosi sp. n. and Tegenaria incognita sp. n., are described. Both species show a significant similarity to T. bucculenta, T. feminea and T. montigena, a species group restricted to the Iberian Peninsula. T. barrientosi sp. n. can be separated by the pyramidal shaped ventral branch of the conductor, the shape and arrangement of the RTA and the proportion of the bulblength to the cymbium-length, the run and shortness of the copulatory ducts with the diverticulae originating laterally and the irregularly sclerotized egg-shaped spermathecae, which are touching each other anteriorly. T. incognita sp. n. can be separated by the very broad lateral branch and the almost completely hidden lateroventral branch of the RTA, the shape of the conductor with the terminal end pointing towards posterior, the inwards directed epigynal teeth, the run and shortness of the copulatory ducts with the anteriorly originating diverticulae.

Malthonica eleonorae (Brignoli) is redescribed. It can be distinguished from T henroti, which we regard as its sister species without yet proposing a new combination, by the number of teeth on the upper margin of the cheliceral groove and by the spine formulae of all leg tibiae. Additionally, the rim of the atrium, the form of the spermathecae, as well as the shape of the tegular apophysis and the ridge on the male bulb are important characters for separating these species. The female described under T henroti by Wunderlich actually belongs to M. dalmatica (Kulczynski). The latter species would be new to Sardinia but has been recorded before on this island under the name T drescoi Brignoli, which we consider as a new junior synonym of M. dalmatica. In addition, Malthonica sicana Brignoli is recorded for the first time from Sardinia, and the species is redescribed here. Males of the three species, M. sardoa, M. sicana and M. arganoi (Brignoli), can be distinguished by the shape of their retrolateral tibia apophysis, the shape of the median apophysis.

Of the 11 Tegenaria species known from Switzerland, T. mirifica and T. tridentina can only be found in the Alps. Because specimens of the rare species, T. mirifica. are needed for a taxonomic project, a three day collecting expedition has been carried out. Due to the very exact descriptions of the finding site in Ramosch (Grisons), several specimens of the wanted species could he found. At other sites only specimens of T. tridentina and T. silvestris have been collected. This result shows the importance of exact description of finding sites, both geographically and ecologically.
