Back smooth covered with piliform scale-setae (Fig. 18B). Cephalon (Fig. 18C, D) with triangular scutellum slightly depressed in the middle and distinctly separated from vertex but not protruding above it; frontal line continuing the scutellar upper margin; postscutellar line reduced; antennary lobes quadrangular, obliquely directed frontwards; eyes absent. Pereonite 1 (Fig. 18E) with posterior margin slightly concave; postero-lateral schisma with outer lobe rounded and distinctly protruding backwards; lateral margin slightly thickened. Pereonites 1-3 with small rounded ventral tooth. Telson (Fig. 18F) trapezoidal, almost as long as wide, with slightly concave sides and truncate apex. Antennula (Fig. 18G) of three articles, tuft of about five aesthetascs.

Mandibles (Fig. 19A, B) with molar penicil consisting of many setae and 2 + 2 free penicils on the left and 1 + 2 on the right mandible. Maxillula (Fig. 19C) outer branch with 4+6 (5 slightly cleft) teeth, inner branch with two stout penicils. Maxilla (Fig. 19D) with bilobed and setose apex. Maxilliped (Fig. 19E) endite with two triangular terminal spines, one subterminal strong seta and triangular spine on medial margin. Pleopod 1 and 2 exopods with monospiracular covered lungs. Uropod (Fig. 19F) with exopod flattened, almost as long as wide; endopod longer than exopod. Male Pereopod 1 (Fig. 20A) carpus with two lines of strong setae with multipointed apices near sternal margin.

Pleopod 1 (Fig. 20C) exopod about twice as wide as long, with broadly rounded medial margin; endopod with apical part thickset, straight, and bearing a row of short setae. Pleopod 2 (Fig. 20D) exopod triangular with slightly concave outer margin bearing single seta; endopod narrow and distinctly longer than exopod. Pleopod 3-5 exopods as in Fig. 20E-G. REMARKS The genus Alloschizidium comprises 12 species with a Tyrrhenian distribution (Schmalfuss 2003; Taiti & Argano 2009). In having the dorsal surface covered with piliform scale-setae, the new species resembles A. sardoum (Arcangeli, 1933) from Sardinian caves, A. remyi (Vandel, 1944) from Corsica, A. eeae Argano & Utzeri, 1973 from Ponza Island, and A. cavernicolum Taiti & Ferrara, 1995 from a cave in southern Tuscany. It differs from A. sardoum and A. eeae in having shorter telson and uropodal exopods as wide as long instead of longer than wide; from A. sardoum, A. remyi and A. eeae in the male pleo- pod 1 exopod without posterior point; from A. remyi also in the absence of any trace of eyes (a single ocellum in A. remyi is distinctly visible, see Taiti & Ferrara 1996)., Published as part of Taiti, Stefano & Montesanto, Giuseppe, 2018, New species of subterranean and endogean terrestrial isopods (Crustacea, Oniscidea) from Tuscany (central Italy), pp. 197-226 in Zoosystema 40 (11) on pages 218-220, DOI: 10.5252/zoosystema2018v40a11, http://zenodo.org/record/3741502, {"references":["SCHMALFUSS H. 2003. - World catalog of terrestrial isopods (Isopoda: Oniscidea).

Pleopod 2 (Fig. 17D) exopod triangular much longer than wide; endopod elongated and much longer than exopod. Pleopod 3-5 exopods as in Fig. 17 E-G. REMARKS Trogleluma was erected by Vandel (1946) as a subgenus of Troglarmadillidium Verhoeff, 1900 to include the new spe- cies Troglarmadillidium (Trogleluma) machadoi from caves in southern Portugal. Reboleira et al. (2015) raised it to genus level and redescribed the type species which is the only species in the genus presently known. The new species differs from T. machadoi in having piliform instead of triangular dorsal scale-setae, the telson with more rounded apex, the male pereopod 7 ischium with concave, instead of straight, sternal margin, the male pleopod 1 exopod with a more pronounced distal part, and the male pleopod 2 exopod with slightly, instead of deeply, concave outer margin (compare Figs 15-17 with Reboleira et al. 2015: figs 33, 34). The record of this new species considerably enlarges the distribution of the genus.

DIAGNOSIS. — A species of Moserius characterized by the male pleopod 1 endopod with the second article having parallel sides, distally with sinuous outer margin and rounded apex, and the male pleopod 2 endopod with apical part bent outwards. ETYMOLOGY. — The new species in named after Dr Gertrud Anna Gruber, Bolzano, for her invaluable help in collecting the specimens. DESCRIPTION Maximum length: ♂, 3.3 mm; ♀, 3.5 mm. Body colourless, ovoidal, outline not interrupted between pereon and pleon (Fig. 4A). Dorsum bearing ribs and tubercles (Fig. 4 A-C): cephalon with three small tubercles on profrons, vertex with one large central tubercle with 3 +3 rounded tips, and 3 +3 rounded tubercles near rear margin; pereonite 1 with 4+4 longitudinal ribs; pereonites 2-6 with 3+3 longitudinal ribs; pereonite 7 with 2+ 2 ribs; pleonite 3 with two large paramedian tubercles. Cephalon (Fig. 4B, C) with short, subquadrangular frontal lateral lobes, directed outwards and not protruding compared with median lobe. Eyes absent. Pereonites 5-7 with epimera slightly pointing backwards (Fig. 4A). Pleonites 3-5 (Fig. 4A, D) with large epimera directed backwards. Telson (Fig. 4D) about twice as wide as long, distal part trapezoidal with concave sides and truncate apex. Antennula (Fig. 4E) of three articles subequal in length, with three long aestethacs at apex. Antenna (Fig. 4F) with fifth article of peduncle slightly longer than flagellum; flagellum of three articles, with three aesthetascs on second article. Mandibles (Fig. 5A, B) with one free penicil on the right and two free penicils on the left. Maxillula (Fig. 5C) outer branch with 4 + 6 teeth, setose stem among outer group of teeth, inner branch with three stout penicils at apex, inner penicil smaller than other two. Maxilla (Fig. 5D) with bilobed and setose apex. Maxilliped (Fig. 5E) endite with stout subtriangular penicil at apex, palp distally rounded with long setae, basal article with two setae. Uropod (Fig. 5F) with flattened protopod; exopod slightly shorter than endopod, with tuft of apical setae; endopod with single apical seta. Male Pereopod 1 (Fig. 6A) with no distinct modifications. Pereopod 7 (Fig. 6B) ischium with slightly convex sternal margin, carpus with large distal lobe on sternal margin. Genital papilla as in Fig. 6C. Pleopod 1 (Fig. 6D) exopod triangular, longer than wide, slightly concave outer margin and straight medial margin; endopod distinctly longer than exopod, second article with parallel sides, distally with sinuous outer margin and rounded apex. Pleopod 2 (Fig. 6E) exopod longer than wide, with concave outer margin and sinuous medial margin; endopod much longer than exopod with apical part bent outwards. Pleopod 3-5 exopods as in Figs 6 F-H. REMARKS The new species is included in the genus Moserius for the dorsal ornamentation, i.e. presence of 4+4 longitudinal ribs on the pereonite 1, 3 + 3 on the pereonites 2-6, 2 + 2 on pereonite 7, and two tubercles on the pleonite 3. As pointed out by Taiti & Ferrara (1995) the genus Moserius is very similar in the dorsal ornamentation to Carloniscus Verhoeff, 1936, which comprises only the species C. dollfusi (Carl, 1908) from south-eastern France and Corsica. Moserius seems to be also very similar to the genus Beroniscus Vandel, 1967 with two cave-dwelling species from Bulgaria (B. capreolus Vandel, 1967) and from Sicily (B. marcelli Vandel, 1969) (see Vandel 1967, 1969). It is uncertain that the three genera are really distinct and a molecular analysis might clarify this problem. To date, the genus Moserius includes three species: M. percoi recorded from caves in Slovenia, Tuscany and the subspecies M. percoi ribaldonei Brian, 1963, from Liguria, M. elbanus Taiti & Ferrara, 1995, from a cave on Elba Island, Tuscany, and M. inexpectatus Reboleira & Taiti, 2015, from a cave in central Portugal. The new species differs from M. percoi in the number and disposition of the dorsal tubercles on the cephalon and in the longer second rib from the median line on the pereonite 1 (see Strouhal 1940 and Taiti & Ferrara 1995); from M. elbanus in having all the ribs on the pereonite 1 of equal length, the presence of a lobe on the male pereopod 7 carpus, and the distal part of the male pleopod 1 endopod with rounded instead of pointed apex (see Taiti & Ferrara 1995); from M. inexpectatus in the absence of dorsal tubercles on the pleonites 4, 5 and telson, and especially in the male pleopod 1 exopod with a rounded instead of sinuous distal margin (see Reboleira et al. 2015).

Pereopod 7 (Fig. 6B) ischium with slightly convex sternal margin, carpus with large distal lobe on sternal margin. Genital papilla as in Fig. 6C. Pleopod 1 (Fig. 6D) exopod triangular, longer than wide, slightly concave outer margin and straight medial margin; endopod distinctly longer than exopod, second article with parallel sides, distally with sinuous outer margin and rounded apex. Pleopod 2 (Fig. 6E) exopod longer than wide, with concave outer margin and sinuous medial margin; endopod much longer than exopod with apical part bent outwards. Pleopod 3-5 exopods as in Figs 6 F-H. REMARKS The new species is included in the genus Moserius for the dorsal ornamentation, i.e. presence of 4+4 longitudinal ribs on the pereonite 1, 3 + 3 on the pereonites 2-6, 2 + 2 on pereonite 7, and two tubercles on the pleonite 3. As pointed out by Taiti & Ferrara (1995) the genus Moserius is very similar in the dorsal ornamentation to Carloniscus Verhoeff, 1936, which comprises only the species C. dollfusi (Carl, 1908) from south-eastern France and Corsica. Moserius seems to be also very similar to the genus Beroniscus Vandel, 1967 with two cave-dwelling species from Bulgaria (B. capreolus Vandel, 1967) and from Sicily (B. marcelli Vandel, 1969) (see Vandel 1967, 1969). It is uncertain that the three genera are really distinct and a molecular analysis might clarify this problem. To date, the genus Moserius includes three species: M. percoi recorded from caves in Slovenia, Tuscany and the subspecies M. percoi ribaldonei Brian, 1963, from Liguria, M. elbanus Taiti & Ferrara, 1995, from a cave on Elba Island, Tuscany, and M. inexpectatus Reboleira & Taiti, 2015, from a cave in central Portugal. The new species differs from M. percoi in the number and disposition of the dorsal tubercles on the cephalon and in the longer second rib from the median line on the pereonite 1 (see Strouhal 1940 and Taiti & Ferrara 1995); from M. elbanus in having all the ribs on the pereonite 1 of equal length, the presence of a lobe on the male pereopod 7 carpus, and the distal part of the male pleopod 1 endopod with rounded instead of pointed apex (see Taiti & Ferrara 1995); from M. inexpectatus in the absence of dorsal tubercles on the pleonites 4, 5 and telson, and especially in the male pleopod 1 exopod with a rounded instead of sinuous distal margin (see Reboleira et al. 2015)., Published as part of Taiti, Stefano & Montesanto, Giuseppe, 2018, New species of subterranean and endogean terrestrial isopods (Crustacea, Oniscidea) from Tuscany (central Italy), pp. 197-226 in Zoosystema 40 (11) on page 202, DOI: 10.5252/zoosystema2018v40a11, http://zenodo.org/record/3741502, {"references":["TAITI S. & FERRARA F. 1995. - Isopodi terrestri (Crustacea, Oniscidea) delle grotte della Toscana (Italia Centrale).

DIAGNOSIS. ��� A blind, colourless species of Paraschizidium characterized by claviform dorsal scale-setae, antennula of three articles, male pleopod 1endopod with bilobed apex. ETYMOLOGY. ��� The new species is named after Dr Franco Ferrara (Florence) for his invaluable contribution on the taxonomy of Oniscidea. DESCRIPTION Maximum length: ♂, 2.3 mm; ♀, 2.8 mm. Body colourless, strongly convex, able to roll up into a perfect ball (Fig. 12A), dorsally covered with claviform scale-setae (Fig. 12B); one line of noduli laterales per side on pereonites, more or less at the same distance from lateral margin (Fig. 12A). Cephalon (Fig. 12 C-E) with a V-shaped scutellum clearly opened dorsally, antennary lobes narrow, quadrangular; eyes absent. Pereonite 1 (Fig. 12F) with posterior margin almost straight, postero-lateral corner slightly sinuous but with no schisma, ventrally with a small rounded tooth. Telson (Fig. 12G) subtriangular, wider than long, with slightly convex sides and broadly rounded apex. Antennula (Fig. 12H) of three articles, second article shortest, five aesthetascs at apex. Antenna (Fig. 12I) with fifth article of peduncle slightly longer than flagellum; second flagellar article about three times as long as first, with two rows of aesthetascs. Mandibles (Fig. 13A, B) with molar penicil semidichotomized and 1+ 3 free penicils on left and 1+ 1 on right mandible. Maxillula (Fig. 13C) outer branch with 4+ 5 (2 cleft) teeth, inner branch with two small stout penicils. Maxilla (Fig. 13D) with bilobed and setose apex. Maxilliped (Fig. 13E) endite with two triangular terminal spines, one subterminal strong seta and a triangular spine on medial corner. Pleopod 1 and 2 with monospiracular covered lungs. Uropod (Fig. 13F) with exopod flattened and wider than long, endopod longer than exopod. Male Pereopod 1 (Fig. 14A) carpus with some strong setae on sternal margin. Pereopod 7 (Fig. 14B) with no distinct sexual modifications, ischium with straight sternal margin. Pleopod 1 (Fig. 14C) exopod trapezoidal, much wider than long, with crenulate outer margin; endopod with bilobed apex, slightly bent outwards and bearing short setae near medial margin. Pleopod 2 (Fig. 14D) exopod triangular, with one seta on outer margin; endopod much longer than exopod.Pleopod 3-5 exopods as in Fig. 14 E-G. REMARKS At present, the genus Paraschizidium comprises four species: P. coeculum (Silvestri, 1897) widely distributed from Spain to Croatia and Hungary, P. hispanum Arcangeli, 1935 from Spain, P. roubali Frankenberger, 1940 from Czech Republic, which is most probably a junior synonym of P. coeculum (Manicastri & Taiti 1994), and P. esterelanum Juchault & Legrand, 1962 from France. Two more species from Greece (P. levithae Sfenthourakis, 1995 and P. polyvotisi Sfenthourakis, 1995) are presently included in the genus but they should belong to the genus Schizidium Verhoeff, 1901. In fact, Schmalfuss (2008) clearly stated that all the Greek species of Paraschizidium possessing a schisma on the pereonite 1 should be transferred to the genus Schizidium, even if he forgot to include those two species in the list of Schizidium species (S. Sfenthourakis pers. comm.). The new species is readily distinguished from P. coeculum and P. roubali in having claviform instead of piliform dorsal scale-setae; from P. hispanum in having the antennula of three instead of two articles, the male pereopod 7 ischium with straight instead of concave sternal margin, the male pleopod 1 endopod slightly, instead of distinctly, bent outwards. Paraschizidium ferrarai n. sp. is similar to P. esterelanum in having the antennula of three segments and the same shape of the uropodal exopod; it differs in the male pleopod 1 exopod trapezoidal instead of rectangular, with outer margin crenulate instead of straight, and in the endopod with distinctly bilobed apex. As pointed out by Manicastri &Taiti (1994) the populations reported by Vandel (1962) as P. olearum, or at least some of them, might belong to the new species P. ferrarai n. sp.

The new species considerably enlarges the genus distribution towards the West. The new species is readily distinguished from T. kratochvili and T. trebinjanum in the uropodal exopods not surpassing the apex of telson and in the shape of the telson with a broader distal part; from T. trebinjanum also in the male pereopod 7 ischium with straight instead of concave sternal margin (compare Fig. 11B and Strouhal 1939: fig. 12); from T. ruffoi in the telson being longer than wide, the uropodal exopod being comparatively longer, the male pleopod 1 exopod with sinuous outer margin and endopod with apical part pointed and bent outwards instead of rounded (compare Ferrara & Taiti 1996)., Published as part of Taiti, Stefano & Montesanto, Giuseppe, 2018, New species of subterranean and endogean terrestrial isopods (Crustacea, Oniscidea) from Tuscany (central Italy), pp. 197-226 in Zoosystema 40 (11) on page 208, DOI: 10.5252/zoosystema2018v40a11, http://zenodo.org/record/3741502, {"references":["FERRARA F. & TAITI S. 1996. - Typhlarmadillidium ruffoi nuova specie di isopodo terrestre dei Colli Euganei (Padova) (Crustacea, Oniscidea, Armadillidiidae).

REMARKS The new species is included in the genus Leucocyphoniscus for the pattern of dorsal ornamentation, i.e., two paramedian large ribs on the pereonites and a single large tubercle on the pleonite 3. The genus was previously known only from three species: L. verruciger Verhoeff, 1900, from Monte Generoso (southern Switzerland) and Como Province (northern Italy); L. solarii Brian, 1914, from some caves in Como Province; and L. torrii Arcangeli, 1946, from Grotta del B��ter (or Grotta di Opreno), Lecco Province (northern Italy). Although the descriptions of these species are not detailed and with poor illustrations, our specimens are definitely belonging to a new species. It differs from all the other species in the disposition of the dorsal tubercles on the cephalon and the extreme development of the median tubercle on the pleonite 3. It also differs from L. verruciger in having the antennula with two instead of three aesthetascs (compare Fig. 1E and Arcangeli 1923: fig. 6a) and in the male pleopod 1 exopod with a rounded instead of pointed apical part (compare Fig. 3D and Arcangeli 1923: fig. 8b).

REMARKS Moserius talamonensis n. sp. differs from all the other species in the number and disposition of the dorsal tubercles on the cephalon and on the pereonite 1; from M. inexpectatus also in the absence of dorsal tubercles on the pleonites 4 and 5 and telson, and in the male pleopod 1 exopod with a rounded instead of sinuous distal margin. In the shape of the male pleopod 1 exopod, the new species is similar to M. elbanus and M. gruberae n. sp., from which it differs also in the shape of the distal part of the male pleopod 1 endopod., Published as part of Taiti, Stefano & Montesanto, Giuseppe, 2018, New species of subterranean and endogean terrestrial isopods (Crustacea, Oniscidea) from Tuscany (central Italy), pp. 197-226 in Zoosystema 40 (11) on pages 204-208, DOI: 10.5252/zoosystema2018v40a11, http://zenodo.org/record/3741502, {"references":["TAITI S. 2007. - Gli Isopodi terrestri, in SCAPINI F. & NARDI M.

Genus Alloschizidium Verhoeff, 1919 TYPE SPECIES. ��� Armadillidium pruvoti Racovitza, 1907 by monotypy. REMARKS Schmalfuss (2008) pointed out that all the genera of Armadillidiidae possessing a schisma on the pereonite 1 (Eluma Budde-Lund, 1885, Ballodillium Vandel, 1961, and Alloschizidium) fall within his definition of the genus Schizidium Verhoeff, 1901. However, he was not certain that all these genera belong to a monophyletic group and the presence of the schisma might be due to convergence. Therefore, he kept Schizidium as a separate genus distributed from Greece to Iran. The genus Alloschizidium appears to be very similar to Paraschizidium, with a possible synapomorphic character for these two genera being the subovoidal, instead of spherical, shape of the ball when the animals roll up (see also discussion in Taiti & Ferrara 1996). Then, the autapomorphic characters for Alloschizidium compared with Paraschizidium is the presence of the schisma. As remarked by Schmalfuss (2008) a molecular investigation might help to clarify the interrelationships among all the above mentioned genera., Published as part of Taiti, Stefano & Montesanto, Giuseppe, 2018, New species of subterranean and endogean terrestrial isopods (Crustacea, Oniscidea) from Tuscany (central Italy), pp. 197-226 in Zoosystema 40 (11) on page 217, DOI: 10.5252/zoosystema2018v40a11, http://zenodo.org/record/3741502, {"references":["RACOVITZA E. 1907. - Biospeologica.
