Descriptive osteology of Garra rossica (Nikolskii, 1900)
2020Co-Authors: Maryam Saemi-komsari, Soheil Eagderi, Hamed Mousavi-sabet, Masoud Sattari, Saber Vatandoust, Ignacio DoadrioAbstract:To describe the osteological structure of the Garra rossica, ten specimens were collected from the Mashkid Basin, Iran. After fixation into 10% buffered formalin, they were cleared and stained for osteological examination. Then its detailed osteological description was provided and compared with the available congeners in the genus Garra and other cyprinids. Based on the results, some differences have been found in different bones, including neurocranium, upper and lower jaws, pectoral and pelvic girdles, dorsal, anal and caudal fins skeleton, and circumorbital series.

Tashan Cave a new cave fish locality for Iran; and Garra tashanensis, a new blind species from the Tigris River drainage (Teleostei: Cyprinidae)
2016Co-Authors: Hamed Mousavi-sabet, Saber Vatandoust, Yaser Fatemi, Soheil EagderiAbstract:A new cave fish locality is reported for Iran, and the first true cave species is described from the Tigris River drainage. Garra tashanensis , new species, from Tashan Cave, the Tigris River drainage in Iran, is distinguished from its congeners by the combination of characters, including lacking pigment and eyes, having a well-developed round mental disc, two pairs of barbels, a well-developed rostral cap, no obvious pores on lateral line, and rare scales on anterior body. Garra tashanensis sp. nov. furthers differs substantially in its DNA barcode from the subterranean congeners (K2P nearest-neighbor distance of 10.4% to G. lorestanensis and 11.8% to G. typhlops ).

Dressing down: convergent reduction of the mental disc in Garra (Teleostei: Cyprinidae) in the Middle East
Hydrobiologia, 2016Co-Authors: I. Hashemzadeh Segherloo, Hamid Reza Esmaeili, Golnaz Sayyadzadeh, Soheil Eagderi, Asghar Abdoli, Louis Bernatchez, Eric M. Hallerman, Matthias F. Geiger, Müfit Özuluğ, J. LarocheAbstract:In the Middle East, species of Garra are believed to have invaded the area in two independent waves from the Indo-Malayan biogeographic region. This hypothesis is based on the structure of the mental disc, a unique specialization of the lower lip, which is believed to be an adaptation to fast-flowing waters. While several species have such a mental disc, others completely lack a mental disc, being adapted to slow-moving water or to subterranean life. In this study, the phylogenetic relationships of Middle Eastern Garra species, including 16 described and 4 undescribed species, were analysed using mitochondrial cytochrome c oxidase I sequences. The results are concordant with traditional hypotheses on two invasion events; however, these invasion events are independent from the presence, absence or shape of the mental disc. We postulate convergent reduction of the mental disc in 5–6 independent lineages of Garra in the Middle East.

Review of the genus Garra Hamilton, 1822 in Iran with description of a new species: a morpho-molecular approach (Teleostei: Cyprinidae)
Iranian Journal of Ichthyology, 2016Co-Authors: Hamid Reza Esmaeili, Golnaz Sayyadzadeh, Brian W. Coad, Soheil EagderiAbstract:The Iranian species of the genus Garra are reviewed, and diagnoses are presented for all recognized species. Garra gymnothorax , G. lorestanensis, G. mondica , G. nudiventris , G. persica , G. rossica , G. rufa , G. typhlops and G. variabilis are considered valid. Discognathus crenulatus Heckel, 1847 is considered as a synonym of G. rufa . One new species is described, Garra amirhosseini , from the Tigris River drainage in Iran distinguished from its congeners by having 7½ branched dorsal-fin rays, breast and belly with very small scales which are fully covered by a thick epidermal layer, and 9+8 branched caudal-fin rays. Garra amirhosseini is also distinguished from all other of congeners in the Persian Gulf basin except a species without a mental disc, G. elegans , by having two fixed, diagnostic nucleotide substitutions in the mtDNA COI barcode region. Maximum Likelihood based estimation of the phylogenetic relationships placed the sequenced fishes into 16 groups which showed between 0.62% ( Garra amirhosseini vs. Garra elegans ) and 17.6% ( Garra variabilis vs. Garra barreimiae ) K2P sequence divergence in their COI barcode region.

Reproductive biology of Garra regressus and Garra tana (Cypriniformes: Cyprinidae) from Lake Tana, Ethiopia
Journal of Threatened Taxa, 2015Co-Authors: Akewake Geremew, Abebe Getahun, Eshete DejenAbstract:The reproductive biology of Garra regressus and Garra tana was investigated by collecting monthly samples (January to December 2006) from the southern Gulf of Lake Tana, where these species are endemic. Garra regressus has an extended breeding time from April to October while G. tana breeds throughout the year with a peak from March to July. The mean size at maturity in both the species was not significantly different between the sexes, but G. tana had a significantly lower mean size at maturity than G. regressus in female specimens. Absolute fecundity estimates for G. regressus ranged from 580.8–1800, while those for G. tana ranged from 538.9–2968. Egg size frequency distribution revealed that G. regressus is a multiple spawner, while G. tana is a single spawner. The sex ratio in the total catch of G. regressus was found to be skewed in favour of females (Chi-square, P< 0.05), while those for G. tana was not significantly different from 1:1. The mean size at maturity was not significantly different between the sexes for G. tana .

an overview of labeonin relationships and the phylogenetic placement of the afro asian genus Garra hamilton 1922 teleostei cyprinidae with the description of five new species of Garra from ethiopia and a key to all african species
Zoological Journal of the Linnean Society, 2007Co-Authors: Melanie L. J. Stiassny, Abebe GetahunAbstract:A clarification of the morphological character data supporting the hypothesis of labeonin monophyly, and also for one of its subgroups, the Garraina, is presented. As an aid to ongoing studies, a full listing of putative labeonin genera is provided. Included in the Garraina is the widespread and taxonomically problematical Afro-Asian genus Garra. Getahun (2000) in an unpublished thesis clarified much of the taxonomic confusion surrounding the African members of this genus, and we summarize many of his conclusions in the form of an artificial identification key for all 17 valid species of Garra on the African continent. The diversity of Garra in Ethiopia, the geographical centre of species diversity for the genus in Africa, is resolved and redescriptions of the six species previously recognized in Ethiopian inland waters are provided, along with formal taxonomic descriptions of an additional five new species from that country. Four of the new species are endemic to Ethiopia: Garra regressus sp. nov., Garra duobarbis sp. nov., Garra geba sp. nov., and Garra tana sp. nov., whereas the fifth, Garra dembecha sp. nov., is more widespread and found also in Eritrea, Kenya, and Tanzania in eastern Africa. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society, 2007, 150, 41–83.

Revision of the Garra species of the Hajar Mountains in Oman and the United Arab Emirates with the description of two new species (Teleostei: Cyprinidae).
Zootaxa, 2020Co-Authors: Sandra Kirchner, Luise Kruckenhauser, Arthur Pichler, Kai Borkenhagen, Jörg FreyhofAbstract:The Garra species inhabiting the Hajar Mountains are revised and five species are recognised, two of which are newly species described herein. Garra barreimiae, from the United Arab Emirates (UAE) and Northern Oman, is distinguished from other Garra species in the Hajar Mountains by a strongly mottled flank pattern with individual or series of midlateral orange scales, a white dorsal-fin tip, an orange spot at the upper operculum, and more gill rakers on the lower limb of the first gill arch. Garra barreimiae shawkahensis is a synonym of G. barreimiae. Garra gallagheri, from the Wadi Bani Khalid drainage in Oman, is distinguished by flank-scale margins the same colour or slightly darker than the centre of the scales. Garra longipinnis, from the interior wadis in the Central Hajar Mountains in Oman, is distinguished by flank-scale margins being clearly darker than the centre of scales. The original description of G. longipinnis was based on a few individuals with very large fins, which are here considered aberrant. Garra shamal, new species, from the coastal drainages around Muscat in Oman, is distinguished by a strongly mottled flank pattern usually without orange midlateral scales, a white dorsal-fin tip, no orange spot at the upper operculum, and middle caudal-fin rays and membranes the same colour or slightly darker than the rest of the fins in colouration. Garra sharq, new species, from the Wadi Kabbah drainage and a few interior springs in Oman, is distinguished by a strongly mottled flank pattern with individual or series of orange midlateral scales, no orange spot at the upper opercle, and dorsal-fin tip and membranes between central caudal-fin rays the same colour as the rest of the fins. All five species are well differentiated genetically and form distinct mitochondrial clades with between 2.1 and 9.2% differences (p-distances) in the mitochondrial COI.

Garra roseae, a new species from the Makran region in southern Iran (Teleostei: Cyprinidae).
Zootaxa, 2019Co-Authors: Hamed Mousavi-sabet, Maryam Saemi-komsari, Ignacio Doadrio, Jörg FreyhofAbstract:Garra roseae, new species, is described from the stream Tang-e-Sarhe in the Iranian Makran region. It is distinguished from its congeners in the Middle East by lacking barbels, having a small mental disc, 42-58 total scales along the lateral line, 24-30 scales along the predorsal midline, and 20-24 circumpeduncular scales. It is further characterised by having five diagnostic nucleotide substitutions and a minimum K2P distance of 5.39% to G. rossica and 5.49% to G. nudiventris in the mtDNA COI barcode region. Garra phryne from eastern Iran is considered to be a synonym of G. nudiventris.

Garra mondica , a new species from the Mond River drainage with remarks on the genus Garra from the Persian Gulf basin in Iran (Teleostei: Cyprinidae)
Zootaxa, 2015Co-Authors: Golnaz Sayyadzadeh, Hamid Reza Esmaeili, Jörg FreyhofAbstract:Garra mondica, new species, from the Mond River drainage in Iran is distinguished from its congeners by having 7½ branched dorsal-fin rays; the breast, belly and back in front of the dorsal-fin origin naked and 9+8 branched caudal-fin rays. Garra mondica is also distinguished from all other congeners in the Persian Gulf basin, except an unidentified species from the Kol River, by having two fixed, diagnostic nucleotide substitutions in the mtDNA COI barcode region. The identity of G. gymnothorax, a nominal species from the Karun River drainage, and G. crenulata, a nominal species from Central Iran, are discussed. Garra populations examined from the Karun have a unique mtDNA COI barcode sequence, but their diagnostic characters are not consistent with the description and syntypes of G. gymnothorax. G. crenulata is considered as a synonym of G. rufa. Two populations of Garra from the Kol River have a sequence of the COI barcode region very similar to G. mondica, but cannot be identified as G. mondica and their identity cannot be resolved here.

Garra rotundinasus a new species of cyprinid fish pisces teleostei from the upper irrawaddy river basin china
2006Co-Authors: E ZhangAbstract:Garra rotundinasus, a new cyprinid species from the upper Irrawaddy River basin in Yunnan, China, is herein described. It shares with G. gravelyi the presence of a snout having a poorly developed proboscis represented by a truncate area in front of the nostrils, a character distinguishing both from all other Southeast Asian and Chinese congeners. The two species are distinct in coloration, morphometric and meristic characters. The sympatrically occurring G. tengchongensis is very similar to G. rotundinasus in possessing 36-37 perforated lateral line scales, 5 or 6 scales between the anus and anal-fin origin, and an anterior position of the anus (anus to anal distance 32.1-51.8% of pelvic to anal distance). Garra rotundinasus can be differentiated from G. tengehongensis in having a more slender caudal peduncle, a larger disc and no dark central band on the dorsal fin.
