Remarks
See Tchesunov (2017) for the most recent and comprehensive revision of the genus. The genus Halirhabdolaimus was proposed by Siddiqi (2012) for a single species, Syringolaimus loofi, and was only compared with the genus Rhabdolaimus. However, the author did not compare Halirhabdolaimus with Syringolamus. The differential diagnoses of both genera match perfectly and thus the proposal of the new genus was entirely unjustified.
