Two
new amphipods species, Niphargus
sahandensis sp. nov. and Niphargus
chaldoranensis sp. nov. from Iran, are described based on the
morphological characteristics and molecular analyses. Bayesian
Inference analyses of COI and
28s rDNA sequence data provided evidence for the validity of the two
species and their placement in Niphargus
genus. N. sahandensis sp.
nov. primarily differs from similar species by having more than two
hook-like retinacles on the inner surface of the pleopods I-III, the
presence of two spines at the base of uropod I and rectangular shape of
propodi in both gnathopods. N.
chaldoranensis sp. nov. is distinguished by its trapezoidal
shape of propodi in gnathopods I to II, the same size of Pereopod V and
VI and 60% size of pereopod VII compared to the total body.
Morphological descriptions with illustrations of the new species, as
well as a DNA-based phylogeny generated from analyses of a multigene
dataset are provided to better understand species relationships.
