97556B6EFFC7FF962AEDFF321B26FDA3.taxon	materials_examined	Material examined MALAYSIA: 1 ♂, 1 ♀ (MZUF), Tioman Island, 23. IV. 1999, leg. L. A. Ballerio. Previous records INDONESIA: Sumatra, Kajoe Tanam (Dollfus 1898).? INDIA: Maddathorai, Travancore (Stebbing 1911); Andaman Islands: South Andaman, Port Blair, Chiryiatapu (Ferrara and Taiti 1982).? WEST MALAYSIA: Kuala Legap, Pelus Valley, Perak (Jackson 1936). Distribution The species is present with certainty on Sumatra (Indonesia) and Tioman Island (Malaysia) while the records from Travancore and Andaman Islands (India) and Perak (Malaysia) need to be confirmed. Remarks The two specimens from Tioman Island (♂ 5.5 mm, ♀ 4.5 mm long) correspond very well to E. coecus from Sumatra as figured by Taiti and Ferrara (1988) and are here illustrated to confirm the identification (Figures 1 and 2). In particular, the following characters are identical to those of the type specimens: the oval, flattened and colourless body (Figure 1 A), shape of cephalon and lack of eyes (Figure 1 B, C), telson triangular with straight sides (Figure 1 E), male pleopod 1 exopod with sinuous outer margin and triangular distal point bent outwards, and endopod straight with bilobed apex (Figure 2 D).	en	Taiti, Stefano, Cardoso, Giovanna Monticelli (2020): New species and records of Exalloniscus Stebbing, 1911 from southern Asia (Malacostraca, Isopoda, Oniscidea).

Body oval, flattened and colourless (Figures 4 A, 22 A). Dorsum covered with large triangular scale-setae (Figure 4 B). Cephalon (Figure 4 C, D) with lateral lobes with rounded apex, slightly protruding laterally; frontal line almost straight, suprantennal line bent down in middle; eyes with three ommatidia. Pereonites 1 - 3 (Figure 4 A, E) with postero-lateral corners right-angled, pereonites 4 - 7 with postero-lateral corners directed backwards. Pleonites 3 - 5 with epimera falciform, protruding backwards. Telson triangular, wider than long, with slightly concave sides and rounded apex (Figure 4 F). Antennula (Figure 4 G) third article with six superimposed aesthetascs plus apical pair. Antenna (Figure 4 H) with fifth article of peduncle shorter than flagellum; ratio of flagellum joints 8: 6: 7. Mandibles (Figure 5 A, B) with molar penicil consisting of several plumose setae; right mandible with 1 + 1 penicils, left mandible with 2 + 1 penicils. Maxillula (Figure 5 C) outer branch with 5 + 6 (4 cleft) teeth and two setae on caudal surface; inner branch with two subequal penicils. Maxilla (Figure 5 D) with bilobed and setose distal part; inner lobe twice as wide as outer lobe; inner lobe with row of thick setae subapically. Maxilliped (Figure 5 E) with rectangular endite bearing penicil; palp basal article with two setae. Pereopods with flagelliform dactylar seta with fine setae at apex. Pereopod 1 carpus with transversal antennal grooming brush. Pereopod 7 (Figure 6 B) basis with distinct water conducting system. Uropod (Figure 4 F) exopod as long as endopod. Male: Pereopod 1 and, to a lesser extent, 2 carpus with long strong setae on sternal margin (Figure 6 A). Pereopod 7 (Figure 6 B) with few strong setae on sternal margin, ischium sternal margin straight. Pleopod 1 (Figure 6 C) exopod triangular, longer than wide, with sinuous outer margin and rounded posterior point; endopod straight, with small rounded lobe on distal inner margin. Pleopod 2 (Figure 6 D) exopod triangular with few setae on outer margin; endopod flagelliform, longer than exopod. Pleopod 3 - 5 exopods (Figure 6 E- G) triangular with few setae on outer margin. Etymology The new species is named after our colleague and friend Dr H. Schmalfuss, SMNS, for his studies on the systematics of Oniscidea on a global scale. Remarks The new species is characterized by colourless body, eyes with three ommatidia, male pleopod 1 with a triangular exopod and endopod with a small rounded distal lobe. A small distal lobe on the male pleopod 1 endopod is also present in Exalloniscus coecus (compare Figure 2 D) but in that species the lobe is located on the distal outer, instead of inner, margin. Moreover, it differs from E. coecus in the presence of eyes, telson with slightly concave, instead of straight, sides, and male pleopod 1 exopod with rounded, instead of acute, distal point. Another species of Exalloniscus is known from Nepal, E. nepalensis. Exalloniscus schmalfussi n. sp. differs from E. nepalensis in having colourless body, male pleopod 1 exopod with wider distal point and endopod with distal part straight with a rounded inner lobe instead of bent outwards and pointed (compare fig. 9 D in Taiti and Ferrara 1988).	en	Taiti, Stefano, Cardoso, Giovanna Monticelli (2020): New species and records of Exalloniscus Stebbing, 1911 from southern Asia (Malacostraca, Isopoda, Oniscidea).

Dorsum covered with large triangular scale-setae (Figure 7 B).

Pereopod 7 (Figure 8 C) sternal margin of merus, carpus and propodus with some strong setae, ischium sternal margin straight. Pleopod 1 (Figure 8 D) exopod triangular, longer than wide, outer margin slightly sinuous, posterior point rounded; endopod distal part bent outward, with subapical flat triangular lobe directed inward. Pleopod 2 (Figure 8 E) exopod triangular with outer margin almost straight bearing few setae; endopod flagelliform, distinctly longer than exopod. Pleopod 3 - 5 exopods (Figure 8 F-H) triangular with few setae on outer margin. Etymology The new species is named for Siam, the former name of Thailand. Remarks The new species is characterized by the colour pattern (brown with pale antennae, pleonites 3 - 5, telson and uropods) and by the shape of the male pleopod 1 endopod with distal part bent outward and bearing a subapical flat triangular lobe directed inwards. A similar colour pattern is also present in E. bicoloratus Taiti & Ferrara, 1988, but in the latter the cephalon and first pereonite are colourless. In having the male pleopod 1 exopod with a long and rounded posterior point, the new species resembles E. maschwitzi and E. sumatranus but it is readily distinguishable from both in the shape of the distal part of the male pleopod 1 endopod.	en	Taiti, Stefano, Cardoso, Giovanna Monticelli (2020): New species and records of Exalloniscus Stebbing, 1911 from southern Asia (Malacostraca, Isopoda, Oniscidea).

Pleopod 2 (Figure 12 E) exopod triangular with few setae on outer margin; endopod flagelliform, longer than exopod. Pleopod 3 - 5 exopods (Figure 12 F-H) triangular with few setae on outer margin. Etymology Latin: tortilis = twisted. The species name refers to the twisted shape of the distal part of the male pleopod 1 endopod. RemarksExalloniscus tortilis n. sp. is easily distinguished from all the other species by the shape of male pleopod 1 endopod, with distal part twisted and slightly bent outward. A similar character is present also in E. papillosus (compare fig. 5 D in Taiti and Ferrara 1988) from which the new species differs in having colourless body, lack of eyes, and different shape of the male pleopod 1 exopod.
