“…Generally, morphometric and meristic characters overlap and are only useful in multivariate space. Molecular techniques and otolith morphometry add confi rmatory evidence to colour patterns (Hrbek et al 2006;Reichenbacher et al 2007) but are not available for older material. Attempts to capture fresh material for molecular or otolith analyses of the new species by colleagues in Iran and Iraq have so far proved nugatory.…”

“…Attempts to capture fresh material for molecular or otolith analyses of the new species by colleagues in Iran and Iraq have so far proved nugatory.

“…Studies over the past 20 years have demon-strated that a series of species exist in endorheic and exorheic basins of Iran as relicts of the Tethys Sea. Th ey were initially recognized by their allopatric distributions and distinct pigment patterns and, later, in some cases by meristic characters, and in other cases principally by molecular characters (Coad 1988(Coad , 2000Hrbek et al 2006).…”

A new species of tooth-carp, Aphanius mesopotamicus (Cyprinodontidae), is described from southern Mesopotamia in Iran and Iraq. It is distinguished from related species by pigmentation (males have clear margins to the unpaired fi ns, no bars on the caudal fi n and 10-15 clearly defi ned fl ank bars; females bear irregular blotches or spots on the fl ank), distribution, and a suite of morphometric and meristic characters in multivariate space (pectoral fi n rays, caudal peduncle length, scales to pelvic fi n and postorbital length in males and pectoral fi n rays, scales to dorsal fi n, predorsal length and total scales in females). Th e description is based on museum specimens and there have been no recent collections of the new taxon.

“…Species are subject to demographic and selective processes that will act to increase or decrease genetic diversity and coalescent depth of individual species (e.g., Avise, 2000;Hey, 2001;Coyne and Orr, 2004). Species may not be morphologically distinct from other species, yet be genetically distinct (e.g., Hrbek et al, 2006), and conversely species may be morphologically distinct without being genetically distinct (e.g., Verheyen et al, 2003;Duda Jr. and Rolán, 2005). Species are real evolutionary groups and not categories which are created as a direct function of perceived distinction (Hey, 2001).…”

DNA barcoding is a recently proposed global standard in taxonomy based on DNA sequences. The two main goals of DNA barcoding methodology are assignment of specimens to a species and discovery of new species. There are two main underlying assumptions: i) reciprocal monophyly of species, and ii) intraspecific divergence is always less than interspecific divergence. Here we present a phylogenetic analysis of the family Potamotrygonidae based on mitochondrial cytochrome c oxidase I gene, sampling 10 out of the 18 to 20 valid species including two non-described species. Potamotrygonidae systematics is still not fully resolved with several still-to-be-described species while some other species are difficult to delimit due to overlap in morphological characters and because of sharing a complex color patterns. Our results suggest that the family passed through a process of rapid speciation and that the species Potamotrygon motoro, P. scobina, and P. orbignyi share haplotypes extensively. Our results suggest that systems of identification of specimens based on DNA sequences, together with morphological and/or ecological characters, can aid taxonomic studies, but delimitation of new species based on threshold values of genetic distances are overly simplistic and misleading.

“…The recent studies have suggested that active geological history of the Zagros Mountains has considerably influenced diversification of the animals in the studied region especially reptiles and freshwater fishes (Rastegar-Pouyani and Nilson, 2002;Hrbek et al, 2006;Teimori et al, 2012). It is particularly true in the case of freshwater fishes because of their especial pattern of distribution, in which geologic divergence can act as a major physical barrier and produce several allopatric populations.…”

Geographically isolated populations of Barbus present remarkable variation with regard to morphometric and meristic characters within Iranian drainage systems; while they are relatively similar in external morphology such as coloration. Present study is the first report on geographical differentiation of Barbus populations in Iran from both morphological and molecular point of views. The morphometric and meristic characters as well as phylogenetic relationships (using sequence data of mtDNA cytochrome b gene) of twelve populations from three drainages (i.e. South Caspian Sea, Orumyieh and TigrisKaroun) were analyzed. The univariate analysis reveals significant morphological differentiation among the populations from the three drainages. The phylogenetic analyses indicate relatively high genetic differentiation among the populations from the mentioned drainages, which are consistent with the observed morphological variation, and correspond well with their biogeographic distribution. However, the result of Automatic Barcode Gap Discovery (ABGD) analysis shows intra-specific differentiation for the sequences from South Caspian Sea drainage, while support the distinction of the specimens from TigrisKaroun drainage as B. lacerta. Since the sequence data of Barbus cyri from Armenia is clustered with individuals from the South Caspian Sea and the morphological comparison, the specimens from that basin are considered as B. cyri and the Orumyieh basin as Barbus sp.
