Diagnosis (Silvestri 1933a; Condé 1984a) Slightly troglomorphic species. Antennae with 25 and 35 antennomeres. Non-protruding frontal process with non-tubercular setae. Pronotum with 1+1 ma, 3+3 la, 2+2 lp macrosetae; mesonotum with 1+1 ma, 3+3 la, 2+2 lp, 1+1 mp macrosetae; metanotum with 1+1 ma, 2+2 lp, 1+1 mp macrosetae; long, barbed notal macrosetae; abundant notal clothing setae. Two (rarely three) ventral tibial macrosetae; subequal claws (1.1) with large lateral crests; posterior claw with no backward overhang. Urotergites I–II with 1+1 post macrosetae; urotergite III with 1+0 la, 1+1 post macrosetae; urotergite IV with 1+1 la, 2+2– 3+3 post macrosetae; urotergites V–VII with 1+1 la, 5+5 post macrosetae; urotergite VIII with 7+7 post macrosetae; abdominal segment IX with 9+9 post macrosetae; urosternite I with 7+7, urosternites II–VII with 5+5, urosternite VIII with 2+2 macrosetae. Male with an area of glandular g 1 setae and enlarged appendages with glandular a 1 setae. Remarks The studied material (see Table S 2 in Supplementary Material) from MSS habitats was collected from inland Greece. Three specimens from Évia show variability in the number of post macrosetae on the third urotergite; they have 2+1, 2+2 and 3+3 post macrosetae, showing the dubious value of the subspecies P. (P.) festae coi. In addition, a juvenile from Montes Orno, Crete, has also been studied and it matches in all chaetotaxic characters with P. (P.) festae festae. In conclusion, we suggest that P. (P.) festae coi should be synonymized with the nominate subspecies. Habitat and distribution Soil-dwelling species previously found on Karpathos and Leros, islands of the Dodecanese Archipelago; also collected in endogean environments at two sites on Crete and at a locality near Izmir, Anatolia, Turkey. It seems to inhabit MSS, where it has also been found at 14 localities in continental Greece., Published as part of Sendra, Alberto, Antić, Dragan, Barranco, Pablo, Borko, Špela, Christian, Erhard, Delić, Teo, Fadrique, Floren, Faille, Arnaud, Galli, Loris, Gasparo, Fulvio, Georgiev, Dilian, Giachino, Pier Mauro, Lukić, Marko, Marcia, Paolo, Miculinić, Kazimir, Nicolosi, Giuseppe, Palero, Ferran, Paragamian, Kaloust, Pérez, Toni, Polak, Slavko, Prieto, Carlos E., Turbanov, Ilya, Vailati, Dante & Reboleira, Ana Sofia P.

Spermatozoid fascicles with a thick spiral filament. Phyletic affinities, habitat and distribution The presence of medial posterior macrosetae on the mesonotum and metanotum relates P. (P.) hoffmanni sp. nov. to almost half of the species in the subgenus Plusiocampa, all living in the European region, including most of the Mediterranean islands. Among them, P (P) festae is probably the closest related species due to the distribution pattern of their notal macrosetae; in spite of the fact that both species live in Crete (Condé 1984a; Silvestri 1933a), they occupy different habitats, P. (P.) hoffmanni sp. nov. in deep subterranean habitats, P. (P.) festae in soil and subterranean superficial habitats. In addition to this ecological difference, there are several important features that allow them to be separated. Plusiocampa (P.) hoffmanni sp. nov. has troglomorphic traits, with longer appendages than P. (P.) festae and more antennomeres and cercal articles, with more complex and more numerous olfactory chemoreceptors within the cupuliform organ. In P. (P.) hoffmanni sp. nov., the claws are slightly unequal to subequal, but with large lateral crests and a backward prolongation of the posterior claws. Additionally, P. (P.) hoffmanni sp. nov. shows a protruding frontal process covered by tuberculated setae, 8+8 macrosetae on the first urosternite and 6+6 on the second to seventh urosternites. Some of these features also separate P. (P.) hoffmanni sp. nov. from P. (P.) rybaki, a poorly described troglomorphic species from the southern Balkan Peninsula (Condé 1956). Plusiocampa (P.) hoffmanni sp. nov. has been collected from the deep zone of 14 caves in the numerous karst areas of Crete (Fig. 204).

Pretarsal lateral process setiform, with plenty of very short proximal barbs. ABDOMEN. Distribution of abdominal macrosetae on tergites: 1+1 post 1 on I–III; 1+1 la, 2+2 lp 1,2 on IV; 1+1 la, 5+5 post 1–5 on V–VII, 8+8 post on VIII; 11+11 (11+12) post on abdominal segment IX. All post urotergal macrosetae thick, long, covered by thin barbs along distal four-fifths; la urotergal macrosetae shorter than post macrosetae, covered by barbs along distal half.

SECONDARY SEX CHARACTERS. Female urosternite I (Fig. 45) with enlarged subcylindrical appendages, each bearing up to 16 glandular a 1 setae in a distal area. Male urosternite I (Fig. 46) without glandular g 1 setae, with moderated large subcylindrical appendages thicker than those of female, each bearing up to 33 glandular a 1 setae. Phyletic affinities, habitat and distribution Although P. (P.) chiosensis sp. nov. has medial posterior macrosetae on the mesonotum and metanotum (sometimes absent in one or two heminota), as do many previously described species of Plusiocampa s. str., a similar reduction in the number of lateral anterior and lateral posterior macrosetae on the mesonotum and metanotum is present in another troglomorphic species, P. (P.) glagra from continental Greece (Condé 1984a). Plusiocampa (P.) chiosensis sp. nov. also shares a couple of noticeable taxonomical features with P. (P.) glabra in their subequal claws and the number of urosternal macrosetae. Nevertheless, the presence of 1+1 lateral anterior macrosetae on the mesonotum, the more abundant macrosetae on all urotergites, including the eighth abdominal segment, and the absence of glandular g 1 setae in males in P. (P.) chiosensis sp. nov. distinguish it from P. (P.) glabra. Plusiocampa (P.) chiosensis sp. nov. is only known from one cave and occupies the deep subterranean spaces, showing highly troglomorphic features (elongation of appendages, antennomeres and articles, and the strengthening of sensorial equipment of the antennae).

Subgenus Dydimocampa Paclt, 1957 Dydimocampa Paclt, 1957: 46. Diagnosis (Paclt 1957; Condé 1996) Dydimocampa shares with Plusiocampa s. str. the same taxonomic features, with the exception of the two dorsal femoral macrosetae. This fact, together with their distribution patterns, suggests that Dydimocampa is an artificial subgenus based on a single apomorphic feature that has probably appeared several times in Plusiocampa s. str. Habitat and distribution The three species treated here are cave-dwellers with a subterranean life-style and they are distributed in three disjunct karst areas in Europe (Fig. 211)., Published as part of Sendra, Alberto, Antić, Dragan, Barranco, Pablo, Borko, Špela, Christian, Erhard, Delić, Teo, Fadrique, Floren, Faille, Arnaud, Galli, Loris, Gasparo, Fulvio, Georgiev, Dilian, Giachino, Pier Mauro, Lukić, Marko, Marcia, Paolo, Miculinić, Kazimir, Nicolosi, Giuseppe, Palero, Ferran, Paragamian, Kaloust, Pérez, Toni, Polak, Slavko, Prieto, Carlos E., Turbanov, Ilya, Vailati, Dante & Reboleira, Ana Sofia P.

ABDOMEN. Urotergites I–III with 1+1 post macrosetae; urotergite IV with 1+1 (1+0) la, 3+3–2+2 post macrosetae; urotergite V with 1+1 (0+1) la, 4+4 post macrosetae; urotergite VI with 1+1 la, 4+4 post macrosetae; urotergite VII with 2+2 (2+1) la, 4+4 post macrosetae; urotergite VIII with 6+6 post macrosetae; abdominal segment IX with 8+8 post macrosetae; urosternite I with 7+7–8+8, urosternites II–VII with 6+6, urosternite VIII with 2+2 macrosetae. Stylus setae with a few barbs, smooth apically, with basal tooth; 3–5 thin distal barbs on subapical and mediosternal setae. CERCI. Incomplete cerci, a maximum of 5 primary articles have been observed in several specimens. Each primary cercus bears from six to ten disorganized whorls of long, barbed macrosetae, one distal whorl of smooth, long setae and an apical whorl of short, thin setae. GENITAL ORGANS. Male with two to four rows of up to 200 glandular g 1 setae, subcylindrical appendages with a small distal area of up to ten glandular a 1 setae; female with subcylindrical appendages with up to 8 glandular a 1 setae (Figs 155–156). Phyletic affinities, habitat and distribution Several species of Plusiocampa s. str. share important taxonomical features with P. (P.) ternovensis sp. nov., such as the clearly unequal claws with large lateral crests, the posterior claw with a backward overhang and the absence of medial posterior macrosetae on mesonotum and metanotum, but only P. (P.) balsani and P. (P.) affinis share a similar distribution pattern of notal and urotergal macrosetae. Nonetheless, the secondary sexual features of P. (P.) balsani, with the male having subtrapezoidal appendages and glandular a 2 setae, unambiguously isolate it from P. (P.) ternovensis sp. nov. Morphologically and geographically speaking, its closest related species is P. (P.) affinis, but some clear differences separate them. The very unequal claws (1.7–1.8), presence of only one ventral tibial macroseta and the 2+2 lateral macrosetae on the urotergites are features of the new species that are not present in P. (P.) affinis, which has unequal claws (1.3), two ventral tibial macrosetae and 1+1 lateral macrosetae on the urotergites. Plusiocampa (P.) ternovensis sp. nov. has been sampled in three caves at the edge of a karst plateau north of the town of Ajdovščina, in Slovenia. This karst area is in the northern part of the Dinaric Mountains, a transitional zone between the Mediterranean, Alpine, Dinaric and Central European biogeographic regions. In two of the caves, the species lives together with P. (Stygiocampa) nivea, although they segregate differently within the cave. Plusiocampa (P.) ternovensis sp. nov. lives at a wider range of depths, while P. (S.) nivea occupies a deeper zone of the cave, at a depth of 500 m in the Velika ledena jama v Paradani and Bela Griža 1 caves. The temperatures in these two deep caves increase with depth, from permanently under 0ºC (Velika ledena jama v Paradani, with permanent ice in the upper parts) to more than 4ºC in parts deeper than 500 m. In Ledenica pri Dolu, an ice cave with temperatures below 2ºC, we found only P. (P.) ternovensis sp. nov., while in the Bošnarjev brezen Cave (5.9ºC to 7.0ºC) we found only P. (S.) nivea . This suggests that P. (P.) ternovensis sp. nov. may be considered better coldadapted than P.

Urosternite I with 7+7, urosternites II–VII with 6+6, urosternite VIII with 2+2 macrosetae. Male unknown; female with subcylindrical appendages with glandular a 1 setae. Remarks The study of four specimens, a juvenile and 3 females, collected in three caves (see Table S 2 in Supplementary Material) allowed a comparison with the species description, but new topotype material is needed to clarify the taxonomic status of this species (Table 1). The epicuticle of dorsal sclerites is reticulate when observed in high magnification (Fig. 6). Antennae with 34 and 35 antennomeres in two adults, and 40 in the juvenile; adult medial antennomeres 1.6× as long as wide, apical antennomere 2.5× as long as wide; one distal whorl with 20–22 gouge sensilla in each medial and distal antennomere, 36– 38 µm in length (Fig. 4). Cupuliform organ occupies 1/5 of total length of last antennomere, with more than ten spheroidal olfactory chemoreceptors with a central column unfolded in complex expansions with a visible polygonal net with porous surface (Fig. 3). Protruding frontal process with abundant tubercular setae (Fig. 5). Pronotum with 3+3 la macrosetae (2+2 la in original description). Unequal claws (1.4–1.5) with large lateral crests (Fig, 7), posterior claw with a large backward overhang; short lateral anterior pretarsal processes, less than half length of claw, and long lateral posterior pretarsal anterior process overpassing end of claw, as described in type form.

Stylar setae with a few long, thin barbs. Urosternite I with 7+7, urosternites II–VII with 6+6, urosternite VIII with 2+2 macrosetae (Fig. 8). Cerci 1.9× as long as body, with only 6 articles plus base. Habitat and distribution Subterranean species found in four caves, including the type locality in the I-El Koba (= Kizil-Koba, Krasnaya) Сave in the Crimean Mountains. The occurrence of such a distribution for P. (D.) evallonychia in the currently unrelated isolated karst regions of the Crimean Mountains is probably associated with the recent colonization of the caves by the edaphic form of this species in the Würm glacial stage. Such a recent isolation of the populations of this species might explain the absence of differences between them., Published as part of Sendra, Alberto, Antić, Dragan, Barranco, Pablo, Borko, Špela, Christian, Erhard, Delić, Teo, Fadrique, Floren, Faille, Arnaud, Galli, Loris, Gasparo, Fulvio, Georgiev, Dilian, Giachino, Pier Mauro, Lukić, Marko, Marcia, Paolo, Miculinić, Kazimir, Nicolosi, Giuseppe, Palero, Ferran, Paragamian, Kaloust, Pérez, Toni, Polak, Slavko, Prieto, Carlos E., Turbanov, Ilya, Vailati, Dante & Reboleira, Ana Sofia P.

Phyletic affinities, habitat and distribution Among the described species of Plusiocampa s. str., P. (P.) bulgarica, P (P.) elongata, P. (P.) vodniensis and P. (P.) beroni from the Balkan karst region (Condé 1954a; Bareth & Condé 2001; Sendra et al. 2012b), P. (P.) strouhali, P. (P.) caprai, P. (P.) grandii and P. (P.) hoelzeli from the Alps (Condé 1954a; Neuherz 1984) and P. (P.) fagei from caves on Mallorca (Condé 1955b) share two important taxonomic characters with P. (P.) dublanskii sp. nov.: the distinctly unequal claws with large lateral crests and an evident backward overhang on the posterior claw, and the presence of medial posterior macrosetae on the mesonotum and metanotum. Nonetheless, the absence of ventral tibial macrosetae or the extremely unequal claws with unequal lateral pretarsal processes suggest a completely different relationship with the unclear subgenus Venetocampa from the Veneto region, northern Italian Peninsula. These new troglomorphic taxa live in two separated karst regions in the north (Crimea) and the east (Western Caucasus) of the Black Sea. The important differences between the two studied specimens are remarkable, in particular the number and distribution of the macrosetae on the urotergites and abdominal segment, something that should be reviewed in the future with further samples., Published as part of Sendra, Alberto, Antić, Dragan, Barranco, Pablo, Borko, Špela, Christian, Erhard, Delić, Teo, Fadrique, Floren, Faille, Arnaud, Galli, Loris, Gasparo, Fulvio, Georgiev, Dilian, Giachino, Pier Mauro, Lukić, Marko, Marcia, Paolo, Miculinić, Kazimir, Nicolosi, Giuseppe, Palero, Ferran, Paragamian, Kaloust, Pérez, Toni, Polak, Slavko, Prieto, Carlos E., Turbanov, Ilya, Vailati, Dante & Reboleira, Ana Sofia P.

Plusiocampa (Plusiocampa) hoelzeli (Neuherz, 1984) Figs 53–58; Table 5 Torocampa hölzeli Neuherz, 1984: 416, figs 1–23, tables i–ii. Diagnosis (Neuherz 1984) Troglomorphic species. Antennae with 34–35 antennomeres; 10–12 complex olfactory chemoreceptors in cupuliform organ; protruding frontal process with non-tubercular setae. Pronotum with 1+1 ma, 2+2–3+3 la, 2+2 lp macrosetae; mesonotum with 1+1 sma, 1+1 la, 2+2 lp, 1+1 (0+1) smp macrosetae; metanotum with 1+1 lp macrosetae; long, barbed notal macrosetae; long, abundant notal clothing setae. One ventral tibial macroseta (two and three in Renejevo brezno); unequal claws (1.5) with large lateral crests, posterior claw with a backward overhang. Urotergite IV with 0+0–1+1 la, 1+1 post macrosetae; urotergite V with 1+1 la, 2+2–3+3 post macrosetae; urotergites VI–VII with 1+1 la, 4+4 post macrosetae; urotergite VIII with 5+5 post macrosetae; abdominal segment IX with 7+7–8+8 post macrosetae; urosternite I with 7+7, urosternites II–VII with 5+5, urosternite VIII with 2+2 macrosetae. Male with glandular g 1 setae, slightly enlarged subcylindrical appendages with abundant glandular a 1 setae; female with subcylindrical appendages with glandular a 1 setae. Remarks Five specimens (three females, one male and one juvenile) of Plusiocampa were collected at a very deep location,> 1180 m deep in Renejevo brezno, Kanin Mountain, Slovenia (see Table S 2 in Supplementary Material). No other dipluran has yet been found at such a depth, with the exception of specimens of Plusiocampa (Stygiocampa) sp. presently under study from the Lukina jama–Trojama cave system in Croatia, collected by Branko Jalžić (Kazimir Micilinić, pers. obs.). These specimens match the thoroughly described population of P. (P.) hoelzeli found only in Hafnerhöhle, Karawanken Mountains in Carinthia. Nevertheless, there is some variability in important taxonomic features. First, the number of ventral tibial macrosetae on the metathoracic leg, with two (three in one leg) rather than only one; presumably, only the prothoracic legs were observed in the original description. In addition, there is variability in the antennomeres and cercal articles; their mesurements are recorded (Table 5). Body length from 3.4 to 5.1 mm; antennae shorter than body length, with 10–12 complex olfactory chemoreceptors in cupuliform organ; a whorl of gouge sensilla, 34–38 µm long, on each medial and distal antennomere, with an oblique striation (Figs 53–54); small protruding frontal process with slightly tuberculate anterior macrosetae; pronotum with 1+1 ma, 1+1–2+2 la, 2+2 lp macrosetae; mesonotum with 1+1 la, 2+2 lp macrosetae; metanotum with 1+1–0+0 lp (0+1–1+1 slp) macrosetae; unequal claws, posterior claw 1.4–1.5× as long as anterior claw; posterior claw with a large backward overhang (Figs 55–57); urotergite IV with 1+1 la, 1+1 (2+1) post macrosetae; urotergite V with 1+1 la, 2+2–3+3 (3+1) post macrosetae; urotergites VI–VII with 1+1 la, 4+4 (4+3) post macrosetae; urotergite VIII with 6+6 post macrosetae; abdominal segment IX with 7+7–8+8 (8+7) post macrosetae; apical stylus setae with one or two medial thin barbs, subapical and medial setae with a few thin barbs (Fig. 58); cerci longer than body length in adult specimens (Table 5), with several whorls of long, barbed macrosetae on each article in addition to a whorl of smooth, shorter setae in distal position and a characteristic whorl of short, thin setae with a few thin distal barbs in apical position. Habitat and distribution Subterranean species found in a cave in Carinthia (Austria) and another one in the Kanin Mountains (Slovenia)., Published as part of Sendra, Alberto, Antić, Dragan, Barranco, Pablo, Borko, Špela, Christian, Erhard, Delić, Teo, Fadrique, Floren, Faille, Arnaud, Galli, Loris, Gasparo, Fulvio, Georgiev, Dilian, Giachino, Pier Mauro, Lukić, Marko, Marcia, Paolo, Miculinić, Kazimir, Nicolosi, Giuseppe, Palero, Ferran, Paragamian, Kaloust, Pérez, Toni, Polak, Slavko, Prieto, Carlos E., Turbanov, Ilya, Vailati, Dante & Reboleira, Ana Sofia P.

Plusiocampa Silvestri, 1912 Plusiocampa Silvestri, 1912: 141. Diagnosis (Silvestri 1912; Condé 1955 a; Sendra & Weber 2018) Apparently smooth epicuticle, usually reticulated at high magnification, rosetta pores absent. Head with a frontal process with or without tuberculate setae. In non-troglomorphic species, cupuliform organ with four or five spheroidal olfactory chemoreceptors with polygonal net, with pore surface made by at least one cup-shaped fold and a central structure ending in a terminal pore. In troglobiomorphic species, spheroidal olfactory chemoreceptor with more folds in spiral, radial or other complex shape and a more visible polygonal net with pore surface. Sensillum of third antennomere in ventral position. Meso- and metathorax with a few macrosetae but frequently with medial anterior, lateral anterior, lateral posterior and medial posterior (exceptionally medial intermediate and lateral intermediate) macrosetae. Femur with one to five dorsal macrosetae; tibia with one to three ventral macrosetae. Elbow-like claws with usually large lateral crests and setiform lateral processes, rarely with a few barbs on proximal part. Abdomen with lateral anterior and posterior macrosetae and never with medial anterior macrosetae. Sternal macrosetae: sternite I with 6+6 up to 60 macrosetae; sternites II–VII with 4+4 to up to 14+14 macrosetae; sternite VIII with 2+2 up to 4+4 macrosetae. Secondary sexual differences in shape of first urosternite appendages and number of glandular setae. Habitat and distribution This is the most diverse genus of Plusiocampinae, with a clear preference for the subterranean ecosystems (Condé 1955 a; Sendra & Weber 2018). It has 72 species (including the seven new ones described here) and 10 subspecies, distributed around the Mediterranean Basin (Figs 210–211). The exceptions are three Chinese species considered representatives of Plusiocampa by Silvestri (1931 a), Condé (1993 a) and Sendra et al. (2012 a): P. sinensis Silvestri, 1931, P. lipsae Condé, 1993 and P. kashiensis Chou & Tong, 1980. Nevertheless, these species must be removed from Plusiocampa due to the macrosetal formula on urosternites II to VIII. Key to the subgenera and species of Plusiocampa The genus Plusiocampa has been divided into four subgenera based on two characters: the presence of the femoral dorsal macrosetae (Condé 1955 a; Paclt 1957; Sendra & Weber 2018) and the number of tibial ventral macrosetae (Bareth & Condé 1984). Based on these synapomorphies and other characters, the following taxonomic key is proposed for the current five subgenera and 69 species. 1.
