038587B3FFFFF12BE88E7B25E890F9ED.taxon	diagnosis	Diagnosis. Pseudolaguvia magna is distinguished from all its congeners by the following unique characters: a larger body (up to 47 mm SL vs. a maximum of 35.6 mm SL); two pale-brown to cream patches straddling the middorsal region: one rectangular to elliptical patch on mid-interdorsal region, and another indistinct elliptical patch in between the adipose and caudal fins; a broader rhomboidal thoracic adhesive apparatus; a small pale-brown to cream round spot on the ventrolateral side of the head, almost perpendicular to the eye; and no pale-brown to cream-coloured cross-bands on the body (which character it also shares, however, with P. inornata, P. austrina, P. virgulata and P. assula). So far, seven species of Pseudolaguvia are known from the Brahmaputra River drainages (Ng & Tamang, 2012): P. foveolata Ng, 2005 a, P. ferula Ng, 2006 a, P. ri beiroi (Hora, 1921), P. s h aw i (Hora, 1921), P. ferruginea Ng, 2009, P. viriosa Ng & Tamang, 2012 and P. muricata Ng, 2005 b. The first six species are known from northeastern India, and the last from the Rangapani Khal, Bangladesh. The first two species are known from the Tista River and third from one of its tributaries, the fourth from the Mahanadi River below Darjeeling, the fifth from the Raidak River in the state of West Bengal, and sixth from the Sille River in Arunachal Pradesh. Besides a larger body size, P. magna can be further distinguished from all its congeners in the Brahmaputra drainage in lacking (vs. having) pale-brown to cream bands on the body, having (vs. lacking) a roughly rectangular to ovoid pale to cream patch on the mid-dorsal region of the body, and a considerably broader (vs. narrower) thoracic adhesive apparatus. Pseudolaguvia magna is further distinguished from P. foveolata, P. ferula, P. v i r i os a and P. m uri cat a by having a shorter pectoral-fin spine (15.7 – 19.9 % SL vs. 20.2 – 35.7) and pectoral fin (20.7 – 25.5 % SL vs. 27.3 – 38.1, except in P. ferula), and in addition to P. ferruginea, a narrower interorbital width (24 – 27 % HL vs. 27 – 38, except P. ferula). Pseudolaguvia magna is further distinguished from, P. v i r i os a and P. m u r i c a t a by having a shorter dorsal-spine (13.7 – 18.4 % SL vs. 21.2 – 29.0) and longer caudal peduncle (18.0 – 21.0 % SL vs. 12.6 – 17.7); further: from P. ferula, P. ferruginea and P. m u r i ca t a by having a shorter anal-fin base (9.1 – 11.8 % SL vs. 13.2 – 17.7), and a longer snout (51 – 60 % HL vs. 44 – 51, except in P. m u r i ca t a), from P. m u r i c a t a by having a shallower head (12.3 – 16.5 % SL vs. 16.7 – 19.5), caudal fin with a narrower and incomplete (vs. broader and complete) hyaline band in the middle of each lobe (compare Fig. 1 here and fig. 3 in Ng, 2005 b) and lacking (vs. having) prominent black rings on the maxillary and mandibular barbels; from P. ferula by having a longer dorsalfin base (13.0 – 17.8 % SL vs. 7.9 – 11.9); from P. foveolata and P. ferruginea by having a longer predorsal (41.3 – 44.8 % SL vs. 35.3 – 40.8), and fewer vertebrae (27 – 29 vs. 31 – 33); from P. foveolata by having a shorter pelvic fin (13.4 – 15.8 % SL vs. 19.0), adipose-fin base (10.7 – 14.2 % SL vs. 24.0), and nasal barbel (11 – 20 % HL vs. 24), a longer head (28.0 – 31.0 % SL vs. 26.7), greater prepectoral length (23.6 – 27.7 % SL vs. 22.7), and deeper caudal peduncle (7.5 – 9.2 % SL vs. 5.0), and from P. v i r i o s a by having a greater interdorsal distance (16.2 – 20.3 % SL vs. 11.7 – 15.4), and shorter caudal fin (19.9 – 23.7 % SL vs. 26.5 – 32.4). Pseudolaguvia magna is distinguished from P. ribeiroi by having a smooth (vs. serrated) anterior margin of the dorsal spine, narrower interorbital width (24 – 27 % HL vs. 31 – 40), deeper caudal peduncle (7.5 – 9.2 % SL vs. 6.6 – 7.2), and caudal fin with a continuous (vs. discontinuous) dark-brown band extending from the base up to the tip of the median rays, with (vs. without) a narrow hyaline band in the middle of the upper and lower lobes, and the upper lobe with a small and indistinct (vs. broad and distinct) hyaline tip (see Fig. 1 here and fig. 5 b in Ng, 2005 a); from P. shawi by having a shorter adiposefin base (10.7 – 14.2 % SL vs. 15.9 – 20.3) and anterolateral margin of the thoracic adhesive apparatus widely (vs. moderately) extended (see Fig. 1 here and fig. 4 b in Ng, 2005 a). The holotype of P. shawi (ZSI F 10085 / 1) was not in good condition to record most of the morphometric landmarks except for parts of the head. P. magna can be distinguished from P. shawi by having a narrower (24 – 27 % HL vs. 35) interorbital width; and from P. jiyaensis by having a shorter anal-fin base (9.1 – 11.8 % SL. vs. 11.3 – 15.2) and caudal fin (19.9 – 23.7 % SL vs. 22.3 – 29.7), a shorter adipose-fin base (10.7 – 14.2 % SL vs. 13.8 – 18.0), lesser interdorsal distance (16.2 – 20.3 % SL vs. 14.4 – 17.0), and a shorter head (28.0 – 31.0 % SL vs. 30.3 – 33.3). Only two species of Pseudolaguvia have been reported from Myanmar: P. tenebricosa Britz & Ferraris, 2003 and P. tuberculata (Prashad & Mukerji, 1929) known from the Sittang and Irrawaddy river drainages respectively. Pseudolaguvia magna is distinguished from P. tenebricosa by having a longer caudal peduncle (18.0 – 21.0 % SL vs. 15.4 – 17.5) and snout (51 – 60 % HL vs. 45 – 51), a narrower head (19.7 – 23.0 % SL vs. 23.2 – 25.1), shorter caudal fin (19.9 – 23.7 % SL vs. 25.4 – 30.4) and adipose-fin base (see Fig. 1 here and fig. 1 a in Britz & Ferraris, 2003; they mistakenly inserted the caption of P. tuberculata of figure 2 in figure 1, but should be the caption of P. tenebricosa as per Fig. 1 a-e, given in page 2); and from P. tuberculata by having the adipose fin not contiguous (vs. contiguous) with the dorsal-fin base, a shorter caudal fin (19.9 – 23.7 % SL vs. 26.7), and a narrower head (19.7 – 23.0 % SL vs. 26.7). Further, P. magna can be distinguished from both the foregoing species in lacking (vs. having) black rings on the maxillary and mandibular barbels. Pseudolaguvia spicula Ng & Lalramliana, 2010 is the only species of Pseudolaguvia so far known from the Surma-Meghna River system of the Barak River drainage in Mizoram, northeastern India and Meghna River drainage in northeastern Bangladesh. Pseudolaguvia magna is distinguished from P. s p i c ul a by having a shorter caudal fin (19.9 – 23.7 % SL vs. 24.2 – 27.5) and adipose-fin base (10.7 – 14.2 % SL vs. 14.7 – 17.1), a longer caudal peduncle (18.0 – 21.0 % SL vs. 15.4 – 17.9), a narrower interorbital width (24 – 27 % HL vs. 28 – 32), and fewer vertebrae (27 – 29 vs. 30 – 32). Further it can be distinguished by having the caudal fin with a dark-brown (vs. hyaline) patch on median rays. Pseudolaguvia nubila Ng et al., 2013 was discovered from a tributary of Kaladan River in Mizoram, northeastern India. Pseudolaguvia magna is distinguished from it by the following characteristics: a greater predorsal (41.3 – 44.8 % SL vs. 36.6 – 40.6) and interdorsal distance (16.2 – 20.3 % SL vs. 13.1 – 16.8), a shorter analfin base (9.1 – 11.8 % SL vs. 15.6 – 19.7), a shallower caudal peduncle (7.5 – 9.2 % SL vs. 9.1 – 11.1), and fewer vertebrae (27 – 29 vs. 31 – 32). The other members of Pseudolaguvia known from the Ganges drainage are: P. kapuri (Tilak & Husain, 1975) from the Padhoi River near Kalsia Ghat, Uttar Pradesh, northern India; P. flavida Ng, 2009 from the Hooghly (Bhagirathi) River, West Bengal; P. virgulata Ng & Lalramliana, 2010 a from the Barak River drainage, and P. inornata Ng, 2005 b from the Feni River drainage, Bangladesh in the east and P. as s ul a Ng & Conway, 2013 from the Reu River, Chitwan Valley near confluence with Rapti River in Nepal. Pseudolaguvia magna is distinguished from P. virgulata, P. inornata and P. assula by having a shorter pectoral-fin spine (15.7 – 19.9 % SL vs. 20.4 – 28.3); and further from P. virgulata in having a narrower interorbital width (24 – 27 % HL vs. 29 – 35), a shorter dorsal-fin spine (13.7 – 18.4 % SL vs. 21.5 – 24.0), a shorter pectoral fin (20.7 – 25.5 % SL vs. 28.1 – 28.8), a shorter caudal fin (19.9 – 23.7 % SL vs. 28.8 – 30.0), and a shallower head (head depth 12.3 – 16.5 % SL vs. 16.6 – 19.4); and from P. flavida by having a longer snout (51 – 60 % HL vs. 43), a greater: prepelvic length (47.7 – 56.0 % SL vs. 45.9), preanal length (66.7 – 73.7 % SL vs. 63.8), prepectoral length (23.6 – 27.7 % SL vs. 19.5), pelvic-fin length (13.4 – 15.8 % SL vs. 10.2), maxillary barbel length (56 – 73 % HL vs. 43), and outer mandibular barbel length (41 – 56 % HL vs. 34), a shallower body (depth at anus 13.7 – 17.5 % SL vs. 27.6), deeper caudal peduncle (7.5 – 9.2 % SL vs. 6.5), and fewer vertebrae (27 – 29 vs. 32); from P. inornata by having a shorter dorsal-fin spine (13.7 – 18.4 % SL vs. 18.6 – 21.7) and caudal fin (19.9 – 23.7 % SL vs. 27.8 – 29.8); from P. assula by having a shorter pectoral fin (20.7 – 25.5 % SL vs. 27.6 – 32.5) and spine (15.7 – 19.9 % SL vs. 23.3 – 28.3), caudal fin (19.9 – 23.7 % SL vs. 28.2 – 33.2), nasal barbel (11 – 20 % HL vs. 20 – 30) and inner mandibular barbel (24 – 36 % HL vs. 39 – 49), a longer interdorsal distance (16.2 – 20.3 % SL vs. 10.7 – 16.2) and caudal peduncle (18.0 – 21.0 % SL vs. 15.4 – 17.0), a narrower interorbital width (24 – 27 % HL vs. 29 – 36), and a broader (vs. narrower) thoracic adhesive apparatus (see Fig. 2 here and fig. 2 in Ng & Conway, 2013), and from P. kapuri by having a shorter pelvic fin (13.4 – 15.8 % SL vs. 15.3 – 17.9) which does not reach (vs. reaching) the anal-fin origin, caudal fin with a narrower (vs. broader) hyaline cross band at the middle of each lobe, band incomplete (vs. complete), and tip of upper lobe with small and indistinct (vs. broad and distinct) hyaline tip (compare Fig. 1 here and fig. 5 a in Ng, 2005 a).	en	Tamang, Lakpa, Sinha, Bikramjit (2014): Two new species of the South Asian catfish genus Pseudolaguvia from northeastern India (Teleostei: Sisoridae).

038587B3FFF6F12EE88E7E28EE01F85C.taxon	distribution	Distribution and habitat. Known from the Jiya stream (Fig. 7), near Bolik village in Lower Dibang Valley District, Arunachal Pradesh, India (Fig. 8). The Jiya stream is a small tributary of the Kundil stream that flows into the Lohit River above juncture of the Dibang and Lohit Rivers north of the Dibru-Saikhowa sanctuary, near the Assamese town of Sadiya. The stream-water was clear, moderately flowing adjacent to the main road en route to the Shantipur checkgate. Both species (Pseudolaguvia magna and P. j i y a en s i s) occur syntopically and were captured along with species of Psilorhynchus, Barilius, and Danio from the same collection locality in a microhabitat consisting of small to medium-sized stones, pebbles, cobbles with light green algae, and deposits of sand particles near banks. In spite of continuous sampling for about 3 hours at the collection site, no species of Glyptothorax were obtained.	en	Tamang, Lakpa, Sinha, Bikramjit (2014): Two new species of the South Asian catfish genus Pseudolaguvia from northeastern India (Teleostei: Sisoridae).
