A new data of freshwater amphipod of genus Niphargus Schiodte, 1849 from Lorestan Province in Iran

摘要

Niphargus lorestanensis sp.nov., a new species from west of Iran, is described and illustrated based on the analysis of morphological characters. Previous studies supported new species status using the phylogenetic analyses based on COl, 28srDNA and H3 data in Esmaeili-Rineh et al., 2015. This species can be distinguished from other Iranian species by the equal length of palpus to outer lobe in maxilla I, the presence of multiple supporting robust setae in palmar corner of gnathopods I-II, not reaching dactyli to posterior margin of propodi in gnathopods I to II and trapezoid shape of propodi in gnathopods I-II. The Iranian fauna of Niphargus is currently represented by 18 described species.
