“…n. is the equal ratio of the length of rami in uropod I. This character was not observed in other Iranian species (Karaman 1998, Hekmatara et al 2013, Esmaeili-Rineh et al 2015b, 2016a. This character seen only in N. nadarini favitor in the Middle East (Karaman 2012), but, two taxa differ in the ratio of palpus to outer plate length in maxilla I, the number of robust setae at the base of nail in pereopods IV-VII and the number of robust setae in outer surface of palmar corners in gnathopods I-II.…”

“…This region is composed mainly of the karstic carbonate formations, and its karstic aquifers are among the most important karst reservoirs in the western part of Iran (Raeisi & Stevanovic 2010). Due to the wide geographical range and geological conditions coupled with the climatologically diverse environments, the Zagros Mountains range provides a great diversity of species in aquatic and terrestrial habitat types (Smith 1953, Sargeran et al 2008, Akmali et al 2011, Esmaeili-Rineh et al 2016a, EsmaeiliRineh et al 2016b, Afroosheh et al 2016, Fathipour et al 2016, Shahabi et al 2017, Mamaghani-Shishvan et al 2017, and it is considered as a centre for the origin of numerous species (Coad & Vilenkin 2004).…”

Niphargus sarii sp. n. was collected from Jo-Khanem Spring in Ilam Province. This species hypothesis is based on the analysis of morphological characters and 28S ribosomal DNA sequences. In this paper, we describe the morphological traits of this new species. Then, its taxonomic status within the genus is discussed in comparison to the 15 known Iranian species. Results revealed that N. sarii sp. n. is phylogenetically close to N. sohrevardensis. This species is easily distinguished from other Iranian species by some characters, in particular the equal length of rami in uropod I, lack of lateral robust setae on telson and the situation of dactylus to posterior margin of propodus in gnathopod II.

“…For five Niphargus species we had only 28S sequences, and previous studies proved to be genetically and morphologically distinct from other Niphargus species (Hekmatara et al, 2013;Esmaeili-Rineh et al, 2016, 2017a, 2018. These species, however, are known from single sites and could be unambiguously included into the dataset.…”

Range sizes of groundwater amphipods (Crustacea) are not smaller than range sizes of surface amphipods: a case study from Iran

The connectivity of groundwater aquifers is lower compared to surface waters. Consequently, groundwater species are expected to have smaller distributional ranges than their surface relatives. Molecular taxonomy, however, unveiled that many species comprise complexes of morphologically cryptic species, with geographically restricted distributional ranges in subterranean as well as in surface waters. Hence, the range sizes of surface and groundwater species might be more similar in size than hitherto thought. We tested this hypothesis by comparing the range size of surface amphipods of the genus Gammarus and subterranean amphipods of the genus Niphargus in Iran. We re-analyzed the taxonomic structure of both genera using two unilocus species delimitation methods applied to a fragment of the COI mitochondrial marker, to identify molecular operational taxonomic units (MOTUs), and assessed the maximum linear extent (MLE) of the ranges of MOTUs from both genera. Genus Gammarus comprised 44–58 MOTUs while genus Niphargus comprised 20–22 MOTUs. The MLEs of the two genera were not significantly different, regardless the delimitation method applied. The results remained unchanged also after exclusion of single site MOTUs. We tentatively conclude that in this case there is no evidence to consider that groundwater species are geographically more restricted than surface species.

“…Also, the maxillar palpus in N. urmiensis sp. nov. is short and not reaching the tip of the outer lobe of maxilla I, this character is rare among niphargids, but it has been reported in N. kermanshahi Esmaeili-Rineh, Heidari, Fišer & Akmali, 2016, N. sohrevardensis Esmaeili-Rineh, Sari, Fišer & Bargrizaneh, 2017, N. borisi Esmaeili-Rineh, Sari & Fišer, 2015and N. ilamensis Esmaeili-Rineh, Sari, Fišer & Bargrizaneh, 2017from Iran and N. auerbachi Schellenberg, 1934 from Switzerland.

This study was conducted to describe and illustrate two new species of groundwater amphipods from the northern parts of the Zagros Mountains in West Azerbaijan Province, Iran. Mitochondrial (COI) and nuclear (28S rDNA) fragments as well as several morphological traits were used to characterize Niphargus urmiensis sp. nov. and Niphargus fiseri sp. nov. The phylogenetic analyses showed that the nucleotide differences between the recently described species and their close allies are attributed to their distinctiveness. The molecular analysis also introduced that the new species are placed within the clade comprising Iranian species as a sister taxon. The genetic distances between N. urmiensis sp. nov. and N. fiseri sp. nov. are 7.6% and 1.6%, respectively based on the COI and 28S rDNA gene fragments.
