The name “lorestanensis” refers to Lorestan Province (Iran), where the species was found. Remarks and affinities. According to Esmaeili-Rineh et al. (2015b), the Shol-Abad and Abrahmeh populations form a single species based on 28s rDNA, CO1 and H3 sequences. Unfortunately, due to the lack of sample, there is no information about morphological characters of Abrahmeh population. It seems N. lorestanensis sp. nov. has a sister relationship with N. darvishi and N. persicus (Esmaeili-Rineh et al. 2015a). Niphargus persicus differs from N. lorestanensis in the ratio of maxillar palpus to outer lobe, the shape of gnathopod I propodi, the status of dactyli in gnathopods I to II. The survey of diagnostic characters suggests that several Iranian species (N. bisitunicus, N. sharifii and N. ilamensis) bear multiple supporting robust setae on both of gnathopods propodi (Esmaeili-Rineh et al. 2015a), however, the first two species have rectangular shaped propodi. Niphargus lorestanensis is diagnosed from N. bisitunicus in equal length of maxillar palpus to outer lobe, pluritooth robust setae on the outer lobe of maxilla I, the lack of lateral robust setae on each telson lobe and the situation of dactyli in gnathopods I and II. Niphargus sharifii has many similarities to the new species; however, N. lorestanensis is different in the number of robust seta in dorsal margin of urosomites I–III, the status of the dactyli to the posterior margin of the propodus in both gnathopods and the number of robust seta in outer margin of the propodi in gnathopods I–II (Esmaeili-Rineh et al. 2015a). Third diagnostic character is observed only in N. sharifii and N. alisadri between the Iranian species. The new species is distinguished from N. alisadri by the shape of propodus in gnathopod II, the number of robust setae in dorsal margin of urosomites I–II, the number of lateral robust seta on each telson lobe and the ratio of distal to proximal articles in the outer ramus of uropod III (Esmaeili-Rineh & Sari 2013, Esmaeili-Rineh et al. 2015a). The last diagnostic character, in addition to the new species, is also seen in N. sarii, N. hosseiniei and N. ilamensis (Esmaeili-Rineh et al. 2017b; Esmaeili-Rineh et al. 2018). But in all of them except, N. ilamensis, the dactyli of gnathopod I are reaching to the posterior margin of the propodus. Therefore, N. lorestanensis is similar to (this character) only N. ilamensis. The new species shares traits with N. ilamensis, including the number of distal robust setae on each telson lobe, the ratio of inner to outer ramus of uropod I and the ratio of distal to proximal article in outer ramus of uropod III. However, N. lorestanensis is separated from N. ilamensis by the lack of robust setae on dorsal margin of urosomite III, the shape of gnathopod II propodi and the ratio of maxillar palpus to outer lobe.Published as part of Esmaeili-Rineh, Somayeh, 2018, A new data of freshwater amphipod of genus Niphargus Schiödte, 1849 from Lorestan Province in Iran, pp. 242-250 in Zootaxa 4531 (2) on pages 243-246, DOI: 10.11646/zootaxa.4531.2.5, http://zenodo.org/record/261459

Remarks Niphargus urmiensis sp. nov. is characterized by two traits. The first one is the presence of one spine with lateral projections on the outer surface of the palmar corner in gnathopods I–II propodi. This character has been reported in N. bisitunicus Esmaeili-Rineh, Sari & Fišer, 2015 and N. fiseri sp. nov., however, both latter species bear the lateral spines in each telson lobe. 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, 2015 and N. ilamensis Esmaeili-Rineh, Sari, Fišer & Bargrizaneh, 2017 from Iran and N. auerbachi Schellenberg, 1934 from Switzerland. Niphargus urmiensis sp. nov., however, differs in the lower numbers of spines on the outer surface of the palmar corner of gnathopods I–II.Published as part of Mamaghani-Shishvan, Mahmoud & Esmaeili-Rineh, Somayeh, 2019, Two new species of groundwater amphipods of the genus Niphargus Schiödte, 1849 from northwestern Iran, pp. 1-23 in European Journal of Taxonomy 546 on pages 7-13, DOI: 10.5852/ejt.2019.546, http://zenodo.org/record/338275
