Redescription of two Iranian cyclopoids: <i>Thermocyclops tinctus</i> Lindberg, 1936 and <i>Th. hyalinus persicus</i> Lindberg, 1936 (Copepoda, Cyclopoidae)

Two Thermocyclops species, Th. tinctus LINDBERG, 1936 and Th. hyalinus persicus LINOBERG, 1936, both described from Iran, are redescribed in detail after reexamination of the type-series. Th. tinctus appears to belong to a group of species which are characterised by the spinular surface of the leg 4 coupler, the compact genital double-somite, and the relative shortness of the apical spines of the leg 4 endopodite. Th. hyalinus persicus, considered for long as synonymous with Th. crassus, resembles most to Th. vermifer. The particular morphology of the principal seta on the caudal rami appears to be typical for the Iranian populations, named Th. vermifer persicus
