Seven species of the family Panagrolaimidae are described from natural areas in Kerman province, Iran: Panagrolaimus concolor; P. facetus; P. cf. labiatus; P. cf. papillosus; P. cf. subelongatus; P. superbus and P. trilabiatus were recovered. Descriptions, measurements, illustrations and light microscopic photographs are provided for all species. Molecular analysis of three out of seven species based on sequences of the 18S rDNA places P. facetus close to P. davidi (HQ270131) and an unidentified Panagrolaimus (EU040129), only in the Maximum Likelihood (ML) tree. In the Bayesian Inference (BI) tree it groups with an unidentified Panagrolaimus (KC522709). Panagrolaimus trilabiatus groups with P. subelongatus (AY284681) and an unidentified Panagrolaimus (FJ590963) in BI tree. Panagrolaimus cf. papillosus groups with P. davidi (HQ270131) and is placed close to P. facetus (KF011488) in the BI tree. In the ML tree it groups with two unidentified Panagrolaimus (KC522708; FJ590961). Molecular data of 18S rDNA of P. facetus, P. cf. papillosus and P. trilabiatus are reported for the first time. In addition, Maximum Likelihood and Bayesian analyses revealed the paraphyly of the genus Panagrolaimus.
