Introduction

 

The bottom dwelling cyprinid fish genus Garra Hamilton, 1822 consists of approximately 70 species distributed from Borneo to West Africa through southern China, South and Southeast Asia, the Middle East, the Arabian Peninsula, and East Africa (Zhang & Chen 2002).  While revising the genus, Hora(1921) recognized 25 species including seven new species from the Himalayan foothills, viz., G. annandalei from Assam and Darjeeling Himalayas, G. abhoyai and G. naganensis from Manipur, G. prashadifrom Uttar Pradesh, G. chaudhurii from northern Bengal, G. jenkinsonianum from Bengal, and G. kempi from Arunachal Pradesh.Other known species from the region are: G. rupecula (McClelland), G. lissorhynchus (McClelland), G. lamta (Hamilton), G.gotyla (Gray), G. nasuta (McClelland) (Hora 1921; Menon 1964). Menon (1964) recognized 38 species under the genus and considered Hora’s(1921) G. abhoyai a junior synonym of G. rupecula; G. chaudurii ofG annandalei; G. prashadi ofG lamta, and G. jenkinsonianumof G. mullya. Nath& Dey (2000) reported seven species of Garra, viz., G. annandalei, G. gotyla gotyla, G. kempi, G. lamta, G. lissorynchus, G. mcClellandi, andG. naganensis from Arunachal Pradesh.  Collections from the Deopani,Ipipani, Sisiri, and Lohit rivers in the Lower DibangValley and the Lohit District in Arunachal Pradesh included an undescribed Garra, which is herein described as Garra arupi sp. nov.

 

Materials and Methods

 

The descriptions are based on formalin preserved specimens. Counts, measurements and terminology follow Kullander& Fang (2004).  Measurements were taken point to point with digital calipers to the nearest 0.1mm.  The number in parentheses after a specific count indicates number of specimens examined. Fin rays and number of scales were counted under a zoom stereoscopic microscope.  Terminology used for description of disc follows Zhang et al. (2002).  Other measurement techniques adopted are as follows: disc width, the widest portion of the lower lip; disc length, length from anterior mid-point of the anterior papillatedskin fold to the posterior mid-point of the posterior margin of mental disc; head height, distance from the midline at occiputvertically downward to ventral contour of the breast; lateral line scales, counted from the anterior-most scale in contact with the shoulder girdle to the last scale on the caudal fin; lateral transverse scales above the lateral line, counted from the dorsal fin origin to the lateral line obliquely ventral and caudal and scales below lateral line are counted from the ventral fin origin obliquely dorsal and rostral to lateral line and also from the anal fin origin to the lateral line. Measurements of the head parts are also given in percentages of head length for comparison with data of literature. For vertebral count, eight specimens were dissected and stained with alizarin S.  Vertebral count includes the first four vertebrae of Weberian apparatus.  Abdominal vertebrae were counted from the first four vertebrae of the apparatus to the last vertebra bearing pleural rib and caudal vertebrae, from the vertebra immediately posterior to the anal fin pterygiophore.  Types of the comparative materials were physically examined for the study.

Discussion

 

There have been several new descriptions and revisions of Garra species in Asia (Vishwanath & Sarojnalini 1988; Kosygin & Vishwanath1998; Vishwanath & Kosygin 2000; Kottelat 2000; Gopi 2001; Zhang & Chen 2002; Kullander & Fang 2004; Vishwanath & Shanta 2005; Zhang 2006).

Nath & Dey (2000) reported the occurrence of Garra naganensis, G. kempi, G. lissorhynchus, G. gotyla, G. annandalei, G. lamta andG. mcClellandi in Arunachal Pradesh. Among them, G.mcClellandi is a peninsular form (Menon 1964; Jayaram 1999). Menon (1964) noted the type locality of G. lamta to be Tinau River, tributary of Rapti River, at Butwal(Nepal) and reported its distribution up to KumaonHimalaya.

Garra arupi sp. nov.is characteristic in having a shallow groove transversely on its snout tip with a band of 6-9 small or large pointed tubercles.  In the specimens having smaller tubercles on the snout tip, there is no such transverse groove.  The new species is similar to G. lamta and G. mullya by the presence of a groove on the snout tip. However, G. lamta and G. mullya have a distinct lateral broad stripe and a black blotch on caudal base which G. arupi does not have.  G. arupi differs from G. lamta in having 35-36 (vs. 31-34) perforated lateral line scales, 11-12 (vs. 8-10) predorsalscales, and vent to anal distance 1.67-1.90 (vs. 4.00-6.67) in pelvic to anal fin distance.  G. arupi further differs from G. mullya in 35-36 (vs. 32-34) perforated lateral line scales, 11-12 (vs. 9-11) predorsal scales, vent to anal distance 1.67-1.90 (vs. 2.67-3.80) in pelvic to anal fin distance, and 2½ (vs. 3½) transverse scales between the pelvic fin and lateral line.

In addition to Garra kempi and G.lissorynchus, there are five species of Garra from the Brahmaputra basin in India, namely G.annandalei, G. naganensis,G. gotyla, G. nasuta, and G. rupecula (Menon1964; Talwar & Jhingran1991; Jayaram 1999).  G. arupi sp. nov. isseparated from them by having a distinct transverse submarginalband on the dorsal fin and an anterior position of the vent.  G. arupi has a vent to anal distance 52.6-60.0 % pelvic to anal distance (vs. 40.6-44.2 in G.naganensis, 30-33.8 in G. annandalei).G. arupi further differs from Menon’s (1964) G. gotylain having 9-10 (vs. 11-12) predorsal scales, a snout without a proboscis and with a mere transverse groove on snout tip (vs. a snout with a prominent proboscis and a prominent transverse groove on the snout tip), presence (vs. absence) of a black band on branched dorsal fin rays, and an absence (vs. presence) of black spots at the base of branched dorsal fin rays. G.arupi differs from Menon’s (1964) G. nasutain having an absence (vs. presence) of a trilobedproboscis with a distinct transverse groove on the snout tip, anterior position of the vent (vent to anal distance 1.67-1.90 vs. 3.71-5.25 in pelvic to anal distance), and an absence (vs. presence) of black spots at the base of branched dorsal fin rays.

Garra rupecula McClelland, 1839 was described from theMishmi Mountains, Assam (now in Arunachal Pradesh) in Brahmaputra basin having the following characteristics: a W-shaped band on the caudal fin and naked scales in the predorsal region (Talwar & Jhingran 1991), which differentiate it from G. arupi sp. nov.  While describing G. abhoyai as a new species from the specimens collected from the area of the Ukhruldistrict in Manipur, Hora (1921) reviewed the description of G. rupecula based on fresh specimens collected from the hill streams of Manipur valley, an altogether different river basin. He did not mention significant differentiating characteristics between the two species except for the small body size and presence of pores on the snout in G. rupecula.  After decades, Menon(1964) also reviewed the characteristics of G. rupeculabased on Manipur valley specimens and put G. abhoyaias its junior synonym.  All the streams and rivers draining in the Manipur valley and Ukhruldistrict belong to Chindwin drainage. Ten specimens (45.0-54.9mm SL) having pores on their snout presently collected from the Iriland Nambul rivers (Chindwin basin) have close similarity with those of Hora (1921) and Menon (1964) mentioned above.  The distribution pattern clearly suggests the validity of G. abhoyai and absence of G. rupecula in the basin.

Garra abhoyaicharacteristically has 16-27 small scales embedded in a thin skin on the predorsal region arranged irregularly, with the size of these scales much smaller than those on the flank scales. It has also a narrow black band in the middle of the dorsal fin, a characteristic that G. arupi sp. nov.does not have.

Vishwanath & Sarojnalini (1988) mentioned the type locality of Garra manipurensisin the Manipur River at Sherou in the Chindwin basin in Manipur.  However, several subsequent collections from the type locality did not represent the species. Instead, it is represented in the collections from Tuivai River in the Brahmaputra River basin, Manipur.  Thus type locality as given in the original description might be due to wrong labeling.  The species has the following combination of characteristics: 4 branched anal fin rays, 13 branched pectoral fin rays, and arostral lobe which easily differentiates it from G.arupi sp. nov. G. arupi further differs from G. manipurensisin having head height 21.8-23.6 (vs. 19.2-20.6% SL), pectoral fin length 20.0-23.4 (vs. 25.3-27.8% SL), pelvic-fin length 17.1-20.2 (vs. 21.7-23.4% SL), pre-anus length 62.4-65.6 (vs. 68.9-72.4 % SL), disc width 56.0-62.8 (vs. 44.7-52.1% SL), disc length 40.7-48.0 (vs. 34.6-35.6% SL), callous pad width 35.0-40.0 (vs. 31.9-34.9 %SL), callous pad length 25.7-30.0 (vs. 20.4-21.9% SL), and an anterior position of the vent (vent-anal distance 52.6-60.0 vs. 24.8-29.7% pelvic to anal distance).

There are four species of Garra from the Chindwin basin in Manipur, namely, G. litanensis, G. paralissorhynchus, G. compressus, and G. elongata (Vishwanath1993; Kosygin & Vishwanath 1998; Vishwanath & Kosygin 2000; Vishwanath& Shanta 2005).  G. arupi sp. nov. differsfrom them in having an anterior position of the vent (vent-anal distance 52.6-60.0 vs. 25.6-51.8 % pelvic to anal distance).  G. arupifurther differs from G. elongata and G. compressus in having 35-36 (vs. 40-41) perforated lateral line scales, and 16 (vs. 12) circumpeduncularscales. G. arupi differs from G. paralissorhynchus in having 35-36 (vs. 32-33) perforated lateral line scales, seven (vs. 6) branched dorsal fin rays, five (vs. 4) branched anal fin rays, and an absence (vs. presence) of a rostral lobe. G. arupi differs from G. litanensis in the absence (vs. presence) of a proboscis, a presence (vs. absence) of scales on the chest, and seven (vs. 8) branched dorsal fin rays.

There are seven species of Garra from the Irrawaddy River basin in Rakhine Yoma, Myanmar, namely Garra propulvinus, G. vittatula, G. spilota, G. rakhinica, G. flavatra, G. poecilura, and G. nigricollis(Kullander & Fang 2004).  All the species (except G. spilota) share a common character, a rostral lobe on the snout, which can be utilized to separate them from G. arupi sp. nov.  G. arupidiffers from G. spilota in having the presence (vs. absence) of a submarginal black band on the dorsal fin, an absence (vs. presence) of blotches on the sides, and seven (vs. 8) branched dorsal fin rays.

Kottelat (1990, 2001) also remarked that most of the highly specialized rheophilicfish species in Southeast Asia have restricted distribution ranges.  So, a thorough revision to present the precise differentiating characteristics and geographical distributions of G.nasuta, G. gotyla,G. rupecula, and Garra mullya would be essential.
