Abstract

Iranocichla persa sp. n. is described from the Shur, Hasanlangi and Minab River drainages fowing into the Persian Gulf at the Strait of Hormuz in southern Iran. It is distinguished from I. hormuzensis, from the Mehran River drainage, by nuptial males having a bright orange breast and lower part of the head (vs. black), a poorly developed or invisible (vs. distinctive) “Tilapia-mark” in the dorsal fn and very clear white spots making almost wavy bars or stripes on the caudal fn (vs. without or with very few white spots). Mitochondrial DNA sequence characters suggest that both Iranocichla species are closely related but form two distinct clades, diagnosable by several fxed mutations in ND2, D-loop and partially by COI sequences. Populations from Kol River drainage, which is situated in-between the Mehran and the Shur River drainages, are more similar to I. hormuzensis in terms of their male nuptial coloration but to I. persa sp. n. in their mitochondrial sequence characters. Teir status requires further investigation.
