Hyastenus hilgendorfi De Man, 1887

Persian Gulf. Kuwait ( Apel 2001), Saudi Arabia ( Basson et al. 1977; Apel 2001), Bahrain ( Stephensen 1946), UAE ( Nobili 1906a), Iran ( Stephensen 1946; Apel 2001; Naderloo & Sari 2007a; present study).

Habitat. Griffin & Tranter (1986) recorded the species from 5-108 m in the Indo-West Pacific. Stephensen’s (1946) material of the species was collected in 3-33 m in the Persian Gulf. Naderloo & Sari’s (2007a) specimens of the species came from depth of 15- 40 m. During the present study a single male was collected at the rocky intertidal zone of Bandar Emam.

Remarks. Hyastenus hilgendorfi is a typical subtidal crab occurring rarely in low-intertidal zone. This species is a very common majid crab in the Persian Gulf ( Naderloo & Sari 2007a). There are four species of the genus Hyastenus known from the Persian Gulf (see Naderloo & Sari 2007b) but only H. hilgendorfi is considered as an intertidal element.
