Similar to <i>N. appenninica</i> except as noted. <i>Carapace</i>: slightly more elongate (CL/CW=1.3, CL/ Ca=1.7), color more pronounced than in <i>N. hastensis</i>, and darker, with strongly contrasting dark and lighter zones, dark parts distinctly mottled, CZ wedge shaped, warm brown, wide and truncated behind eyes and gradually narrowing towards fovea (Fig. 4 F), thoracic part with distinct central grey leaf-pattern with peripheral yellow zones, fovea somewhat irregular shaped, central groove small, clypeus, darker than in previous two species, bristles less developed than in previous two species, absent along carapace edges, pubescence fine silver grey. <i>Eyes</i>: compactly grouped on and around a steep, anteriorly light colored, process (l/w=1.3), lateral eyes larger than median eyes, ALE largest (ALE/PLE=1.2), AER slightly shorter than PER (AER/PER=0.96), light patch between ALE, POP not uniform black. <i>Chelicerae</i>: dorsal dark greenish black with lighter colored glabrous zones, distribution of bristles and structure of rastellum as in previous two species. <i>Maxillae</i>: (l/w=1.8), ventrally grayish brown further as <i>N. hastensis</i>. <i>Labium</i>: (l/w=0.6), darker than maxillae contrasting with other ventral parts, further as in previous two species. <i>Sternum</i>: (l/w=1.3) bright yellow with distinct dark edge, sigilla less visible than in <i>N. hastensis. Legs</i>: color pattern distinct from previous two species with dorsally dark colored femora and more conspicuous glabrous, longitudinal zones on patellae, segments laterally and ventrally much lighter with glabrous longitudinal zones on femora, spine patterns, pubescence, scopulae, claspers and claws as in <i>N. hastensis. Palps</i>: color and bristle pattern as legs, tibia (l/w=1.9) slightly curved upward and less inflated than in <i>N. hastensis</i>. <i>Palporgan</i>: see Fig. 7 A, D. <i>Abdomen</i>: distinctly darker and more intensely colored ventrally gray otherwise similar previous two species. <i>Spinnerets</i>: darker and more intensely colored than in <i>N. hastensis,</i> otherwise similar.</p> <p> Female paratype.

The species is dedicated to Fion Bolzern, firstborn of AB. The species epithet is a name in apposition. Diagnosis. Males (Figures 3 –6, 15) can be separated by the absence of a patellar apophysis (present in torpida - group, except H. vignai Brignoli 1980), the distally tube-like elongated radix (absent in myops - and strinatii -group, plate-like and distally bifid in H. italica) and the distally strongly elongated conductor (broadly rounded in H. italica). Females (Figures 23 –24, 28) can be separated from other Histopona species by the glossy median indented posterior epigynal sclerite (much longer and with anterior margin only moderately indented in torpida -group) with strongly diverging margin (parallel in H. italica), the unpaired “bursa copulatrix” (completely paired copulatory ducts in myops - and strinatii -group) with anterior margin v-shaped (straight or convex in H. italica) and the narrow lateral lobes of the copulatory ducts (broad in H. italica). See also Table 1. Description. Measurements and ratios of male (n= 2, holotype male and paratype male from Pagnona): carapace 2.93–3.27 long, 2.20–2.42 wide.

Copulatory openings located at anteriolateral border of atrium. Copulatory duct first unpaired (“bursa copulatrix”), anteriorly v-shaped, then dividing into paired narrow lateral lobes directing into strongly sclerotized convoluted receptacula; fertilization ducts very short. Distribution. Italy and Switzerland. Lombardian Prealps, from Lago Maggiore to Lago di Garda. Ecology. Records of H. fioni sp. n. refer to forest and open habitats such as beech or fir woods and alpine pastures at moderately high elevation, from 800 to 1600 m. The species also occur in rocky areas at an elevation of 1800–2000 m. Adults are found preferably from spring to autumn.Published as part of Bolzern, Angelo, Pantini, Paolo & Isaia, Marco, 2013, Revision of the Histopona italica group (Araneae: Agelenidae), with the description of two new species, pp. 23-41 in Zootaxa 3640 (1) on pages 28-33, DOI: 10.11646/zootaxa.3640.1.2, http://zenodo.org/record/28364

Copulatory duct first unpaired (“bursa copulatrix”), then dividing into narrow paired lateral lobes directing into strongly sclerotized convoluted receptacula; fertilization ducts very short. Distribution. Italy and Switzerland (Tessin). All along the Western Alps and the Northern Apennine. Ecology. Records of H. leonardoi sp. n. mostly refer to forest habitats (beech woods at an elevation of 1000– 1500 m). The species also occurs at higher elevation in alpine pastures (maximum elevation reached at 2458 m Gabiet, Aosta Valley). In a few cases H. leonardoi sp. n. occurred in caves. Adults are preferably found from spring to autumn.

The two new species described in this work increase the membership of the italica group, which is defined for females by the presence of a glossy, median deeply indented posterior epigynal sclerite and by the unpaired copulatory ducts, and for males by the absence of a patellar apophysis and by the shape of the embolus, originating basal to the protruding radix. During the examination of the material presented here, large differences in the size of the male palp could be observed, even between specimens from the same locality (e.g. 23 from Liguria, La Spezia: Varese Ligure, Passo Cento Croci). Within the examined specimens of H. leonardoi sp. n., two males appeared to be distinctly larger, the palps showing minor morphological differences (Figures 17–18). Likewise, Bolzern et al. (accepted) and Kraus (1955) observed high intraspecific variation in different species of agelenids, like Malthonica picta (Simon 1870) and Tegenaria femoralis Simon 1873. The absence of valid morphological characters (the only significant difference being the size) and the lack of concrete evidence (no different female forms found and syntopy of both male forms - same locality and same time of the year) provide convincing support to consider the larger males as larger forms of the same species. Records of species belonging to the Histopona italica group are known from large parts of Italy (from Calabria to Trentino, along the entire Appenine range, through the Western Alps up to the Lombardian Prealps) (Figure 30). In some cases, specimens of H. italica and H. leonardoi sp. n. were collected at the same locality. Accordingly, the known distribution of H. italica overlaps that of H. leonardoi sp. n. in the district of Maritime Alps and Northern Apennines, the first extending southwards along the Apennines and the latter northwards, along the Alps. It is likely that H. leonardoi sp. n. and H. italica may also occur in French Maritime Alps, but no direct evidence support the presence of this species in France. Records of H. fioni sp. n. are only known from the Lombardian Prealps (Lombardia and southern Trentino in Italy and Tessin in Switzerland). Apparently, no overlap occurs between H. fioni sp. n. and H. leonardoi sp. n., being separated by Lake Maggiore, at the border between Piemonte and Lombardia (Tessin Valley). The same separation is known to occur for Coelotes pickardi tirolensis (Kulczyn'ski 1906) and C. pickardi pickardi O.

ECOLOGY AND DISTRIBUTION Specimens of P. agnellus n. comb. have been collected primarily in talus caves and rocky areas at medium-high altitudes, between 1900 and 2600 m a.s.l. Mammola et al. (2018) consider the species as a troglophile elements. The distribution of the species is centred on the Alpine districts of Maritime Alps and Ligurian Alps. However, the record of one male in Champlas Janvier (Cottian Alps) let envisage a wider distribution, extending north. TAXONOMICAL REMARKS In the original description, Maurer & Thaler (1988) assigned the newly described species to the genus Lepthyphantes Menge, 1866. In lack of males, the diagnosis – and presumably the genus assignation – was based on the morphology of the epigyne, bearing some characteristic lateral extensions at the base of the proscape. The occurrence of males of a possible undescribed species together with females of former Lephtyphantes agnellus at two sites (Galleria Valscura, Valdieri, Maritime Alps and Monte Grai, Triora, Ligurian Alps) allowed to pair males and females. Moreover, the match was confirmed by morphological characters shared by males and females, such as chaetotaxy, cheliceral teeth, stridulatory ridges, abdominal pattern and ocular pattern. Some years after the description of L. agnellus, Saaristo & Tanasevitch (1993, 1996) reclassified the genus Lepthyphantes using a typological approach, examining the morphology of the genital organs, especially males. As a result, most of the European Lepthyphantes species were transferred or assigned to new genera. On the other hand, given the lack of males, L. agnellus was not transferred to any of the newly created genera. Our finding of the unknown male now allows the placement of this species within the genus Piniphantes Saaristo & Tanasevitch, 1996. According to the original description, the genus Piniphantes includes small Linyphiids, having in males an elongated projection at the proximal part of the embolus bearing numerous finger-like protrusion (Saaristo & Tanasevitch 1996). Such character is particularly remarkable in our case (Fig. 7 A). Moreover, other details given in the genus description (Saaristo & Tanasevitch 1996) match our case, such as chaetotaxy and lack of abdominal pattern. The species is then assigned to the genus Piniphantes, with representatives in the area of Tian Shian Mountains (Central Asia) (5 species: P. cinereus (Tanasevitch, 1986), P. macer (Tanasevitch, 1986), P. plumatus (Tanasevitch, 1986), P. uzbekistanicus (Tanasevitch, 1983), P.zonsteini (Tanasevitch, 1989)), Himalaya (one species, P. himalayensis (Tanasevitch, 1987)), Centro-Asiatic-European region (one species, P.pinicola (Simon, 1884)) and Corsica (one species, P. cirratus (Thaler, 1986)). According to the morphology of the male genitalia, P. agnellus n. comb. is similar to P. cirratus, for which the only holotype male is known, preventing any comparison of the female.Published as part of Milano, Filippo, Mammola, Stefano, Rollard, Christine, Leccia, Marie-France & Isaia, Marco, 2019, An inventory of the spider species of Barcelonnette (France), with taxonomic notes on Piniphantes agnellus n. comb.
