Subterranean ecosystems present ideal opportunities to study mechanisms underlying responses to changes in climate because species within them are often adapted to a largely constant temperature. We have characterized the thermal conditions of caves in the Western Alps, and relate these hypogean climate data to the occurrence of Troglohyphantes troglobiontic spiders (Araneae, Linyphiidae). Our data indicate that present distributions reflect Pleistocence glaciation events and also point to specific responses as a consequence of changes in temperature. Constant temperatures recorded inside caves provide an approximation of the mean annual temperature outside, thus we extend the results to a regional scale. Ecological niche modeling is used to predict habitat suitability both in the Pleistocene and under future global warming scenarios. These analyses point toward a future decline in habitat suitability for subterranean spiders and the potential extinction of the most restricted endemic species.

The spider family Linyphiidae comprises 104 species in Turkey that of them eight species are known from the caves, we recently started to conduct intensive taxonomic and faunistic studies on this family. The genus Troglohyphantes was described in 1882 by Joseph as a cave spider from Carniola in western Slovenia. Members of this genus inhabited cave environment, neighbouring habitat and some species of them are true troglobites. A new species of Troglohyphantes Joseph 1881 is described from Turkey. Differences between the new species and related species are discussed. Troglohyphantes turcicus sp. n. (Araneae: Linyphiidae) is described from Buzluk cave in Turkey. Drawing of characteristic features, the male palpal organs and the female genitalia are presented. Key to the species of Troglohyphantes group is given including in T. turcicus sp. n.

This paper deals with species whose range lies entirely (endemics) or predominantly (subendemics) within the political borders of Austria. The evolution and current distribution of Alpine endemics find their chief cause in the advent of the Pleistocene ice-ages, the destruction of much of the former fauna and in different forms of survival as well as migration from southern refugia. A first overview of endemic and subendemic arachnids of Austria shows 11 harvestman and 46 spider species. One hotspot of arachnological endemisms in the Eastern Alps are the north-eastern Calcareous Alps. The Gesause National Park, an exceptional area situated in the Ennstaler Alps (Styria, Austria), contains 6 subendemic harvestman and 12 endemic and subendemic spider species, i.e. 55% and 26% of the Austrian (subendemic) spectrum. Most of these Opiliones are soil-dwelling forms, most Araneae belong to the linyphiid genera Lepthyphantes s. l. and Troglohyphantes. All these species occur from the nival down to the montane zone, and prefer rock habitats, caves, avalanche corridors and natural woodlands. 100% of these harvestman and 57% of these spider species are Critically Endangered up to Vulnerable. So far, there is no legal protection for them. A main threat to those ice-age relicts is climate warming. There is a great need for conservation action on these endemics and for political support for the national park. Intensive basic research is required as well as encouragement for invertebrate specialists, the protection of endemics enshrined in law, conservation programmes and the creation of protected areas based on endemism hotspots, accompanied by public relations activities about these zoological treasures.

Troglohyphantes bornensis, a new species from the western Italian Alps, is here described. According to the features of the male palp and female epigynum the new species can be assigned to Fage's III Group, Deeleman-Reinhold's marqueti group and Pesarini's microcymbium complex. All specimens were collected in the stony debris of Pugnetto caves (province of Turin, Italy), a calcschist cave complex, formerly studied by biospeleologists for the presence of several endemic species. All caves have openings into beech woods at an elevation of approximately 800 m. RIASSUNTO. Viene descritta Troglohyphantes bornensis, una nuova specie delle Alpi occidentali italiane. A partire dalle caratteristiche del palpo del maschio e dell'epigino della femmina, la specie viene assegnata al III gruppo di Fage, al gruppo marqueti secondo Deeleman-Reinhold e, secondo Pesarini, al complesso microcymbium. Tutti gli esemplari provengono dal detrito delle Grotte del Pugnetto (Provincia di Torino, Italia), un sistema di grotte impostato in calcescisto, gianoto per la presenza di numerose specie endemiche. Tutte le grotte si aprono ad una quota di 800 m circa, in boschi di faggio.

Note. This is an epigean species with a disjunct distribution (Central Lombard Prealps and Colli Euganei). At lower elevation it is frequently found in forests while at higher elevation it is found in a variety of cool habitats. According to the remarkable preference of this species for forest habitats, we assume that populations found at higher altitudes in Premolo and Casargo, represent possible relicts of the ancient populations, previously inhabiting forests. In this area forest naturally attains 2000 m a.s.l., but it have been progressively removed for pastoral use. Therefore we assume that the main cause of the disjunct distribution of this species (Central Lombard Prealps /Colli Euganei) might be due to the fragmentation of the original forest., Published as part of Isaia, Marco & Pantini, Paolo, 2010, New data on the spider genus Troglohyphantes (Araneae, Linyphiidae) in the Italian Alps, with the description of a new species and a new synonymy, pp. 1-18 in Zootaxa 2690 on pages 12-13, DOI: 10.5281/zenodo.199535, {"references":["Pesarini, C.

This epigean species is occasionally found in caves. The distribution ranges from the South-western Alps to the Apuan Alps (Tuscany). Pesarini (2001) described T. delmastroi based on specimens from Cissone (Piemonte, Province of Cuneo) and Tornolo (Lombardia, Province of Parma). In the same year Gasparo (2001) described the previously unknown male of T. iulianae from Sesta Godano (Liguria, Province of La Spezia). The illustrations published by the two authors are very similar and indeed seem to show two males of the same species. Although we could not study the specimen described by Gasparo (formally stored at the University of Roma La Sapienza, but apparently lost), the examination of the paratypes of T. delmastroi from Tornolo, together with the material from Piemonte (Isaia et al., 2010) and the specimens here reported from Tornolo and Pavia, allowed the comparison of the lamella characteristica with the one illustrated by Gasparo (2001), suggesting that Troglohyphantes delmastroi Pesarini is a junior synonym of Troglohyphantes iulianae Brignoli., Published as part of Isaia, Marco & Pantini, Paolo, 2010, New data on the spider genus Troglohyphantes (Araneae, Linyphiidae) in the Italian Alps, with the description of a new species and a new synonymy, pp. 1-18 in Zootaxa 2690 on page 9, DOI: 10.5281/zenodo.199535, {"references":["Brignoli, P.

Specimens collected in the caves of the high Pesio Valley, including type locality of T. rupicapra Brignoli, 1971 (= T. vignai Brignoli, 1971 after Pesarini, 2001), exhibit higher degree of troglomorphism (higher depigmentation, reduction of PLE and PME, lowering of the profile of cephalothorax; Figures 15���18) in respect to the northern populations of the same species. Deeleman-Reinhnold (1978) underlines that the troglomorphism in Troglohyphantes species (i.e. loss of pigmentation, reduction of the eyes apparatus, thinning of the integuments, richer spinulation) is directly related to regressive evolutionary phenomena. The same author also points out that the degree of eye reduction within the same population is ���astonishingly uniform��� and that ���the reduction of the optical apparatus keeps pace with the rise of isolating mechanism��� (Deeleman-Reinhold, 1978).

Males of Troglohyphantes lanai are primarily distinguished from other species of Troglohyphantes by the shape of the lamella characteristica (Figure 1). The shape of the epigynum, (Figures 2, 3 and 9) as well as the cymbium (Figure 4) are also diagnostic. The shape of the cymbium and embolus (Figure 6) of T. lanai is closest to that of T. bornensis and T. microcymbium, from which it is readily distinguishable by the shape of the lamella characteristica, the greater body size and the reduced eyes. Based on Pesarini���s complexes (2001), the new species is close to those included in the microcymbium complex. Description. Male holotype: prosoma 1.38 long, 1.23 wide, light-yellowish. Anterior part of prosoma faintly darker. Thoracic region rounded, dorsally with a narrow ridge, marked with a dark longitudinal streak. Cephalic region slightly elevated, interspersed with black bristles starting from the eye region and continuing in three longitudinal rows that converge to the anterior end of fovea. Clypeus slightly indented under the eyes, then convex. Eyes reduced, without pigment (Figure 5). AME smallest. PLE very slightly bigger than PME, ALE slightly larger than PLE.

The species is dedicated to our friend Enrico Lana, Piedmontese biospeleologist, who lead us in the Fenera caves and collected most of the type material. Distribution. The species is confined to several caves of Monte Fenera, section of Pennine Alps, sector of North-western Alps. Biospeleological notes. Specimens of T. lanai have been found among stony debris in the caves of Buco della Bondaccia (2505 Pi/VC; UTM 32 T 4465205062417); Grotta delle Arenarie (2509 Pi/VC; UTM 32 T 4467265062472); Pozzo di San Quirico (2567 Pi/VC; UTM 32 T 4467135061515); Buco delle Radici (2540 Pi/ VC; UTM 32 T 4473555062438); Bocc d���la Mocia (2541 Pi/VC; UTM 32 T 4473495062452); Ciota Ciara (2507 Pi/VC; UTM 32 T 4464745062356). All caves are included in the cave complex of Monte Fenera (limestone with intercalated sandstone), in the municipalities of Borgosesia and Valduggia (about 140 km NE of Torino). All caves have openings into beech woods, with a prevalent northerly aspect to the cave opening. The temperature of Buco della Bondaccia (nearly 500 m in length) and Grotta delle Arenarie (extending for over 3000 m) are constantly about 9 ��C. Pozzo di San Quirico cave extends for 120 m, Buco delle Radici cave for 38 m, Bocc d���la Mocia for 11 m and Ciota Ciara cave for 202 m. The caves and their fauna have been previously studied by several researchers (Jeannel, 1934; Martinotti 1968; Brignoli 1972; Casale 1988; Arn�� & Lana 2005) and several interesting endemic species have been recognised, including Bathysciola adelinae Jeannel (Coleoptera, Cholevidae); Alpioniscus feneriensis (Parona) (Isopoda, Trichoniscidae), Trechus lepontinus Ganglbauer (Coleoptera, Carabidae) and Sphodropsis ghilianii (Schaum) (Coleoptera, Carabidae).

In this paper we describe Troglohyphantes lanai n. sp. from Pennine Alps and the unknown female of T. bonzanoi, from Ligurian Alps. Based on the collection of new material and on the examination of the paratypes, T. delmastroi Pesarini, 2001 is proposed as junior synonym of T. iulianae Brignoli, 1971 (new synonymy). We also provide new faunistic and ecological data on the Italian species of Troglohyphantes, focusing mainly on Central Italian Alps. Phenetic species groups previously proposed in literature for the Italian species have been updated in view of recent literature and new findings. Pesarini’s complexes of species are used to map the species distribution in the Italian Alps.

1. Troglohyphantes cavernicola Keys. is found everywhere in these caves, where the three following necessary conditions exist—total darkness, a saturated atmosphere, and a suitable place for the construction of snares.2. The first pair of legs are used as tactile organs.3. All small winged insects, thysanurans and small myriopods serve as food. Scarcity of food does not entirely limit their distribution.4. They have no known enemies other than themselves.5. While temperature outside the caves does not materially affect the adult spiders themselves, it is probable that to the even temperature at localities between 600 and 1,700 feet from the entrance is due the great number of specimens found at this place.6. Courtship is similar to that of some outside forms.7. Cocooning is rudimentary. The eggs are few and comparatively large.8. The young are white and are thicker set than the adults. Some are hatched with eyes, while others are entirely blind.9. Moulting is comparatively rare and is often fatal. There a...

We designed a comparative study to unravel the phylogeography of two Alpine endemic spiders characterized by a different degree of adaptation to subterranean life:Troglohyphantes vignai(Araneae, Linyphiidae) andPimoa rupicola(Araneae, Pimoidae), the latter showing minor adaptation to hypogean life. We sampled populations of the model species in caves and other subterranean habitats across their known geographical range in the Western Alps. By combining phylogeographic inferences and Ecological Niche Modeling techniques, we inferred the biogeographic scenario that led to the present day population structure of the two species. According to our divergent time estimates and relative uncertainties, the isolation ofT. vignaiandP. rupicolafrom their northern sister groups was tracked back to Middle–Late Miocene. Furthermore, the fingerprint left by Pleistocene glaciations on the population structure revealed by the genetic data, led to the hypothesis that a progressive adaptation to subterranean habitats occurred inT. vignai, followed by strong population isolation. On the other hand,P. rupicolaunderwent a remarkable genetic bottleneck during the Pleistocene glaciations, that shaped its present population structure. It seems likely that such shallow population structure is both the result of the minor degree of specialization to hypogean life and the higher dispersal ability characterizing this species. The simultaneous study of overlapping spider species showing different levels of adaptation to hypogean life, disclosed a new way to clarify patterns of biological diversification and to understand the effects of past climatic shift on the subterranean biodiversity.
