Abstracts
Specimens of the The Brachyuran crab Atergatis roseus (Rüppell, 1830), were collected for first times from
Iraqi coast, south Al-Faw, Basrah city, Iraq, in coast of northwest of Arabian Gulf. Morphological features and
distribution pattern of this species are highlighted and a figure is provided. The material was mostly collected
from the shallow subtidal and intertidal areas using trawl net and hand.
Keywords xanthid crab; Atergatis roseus; Brachyura; Iraqi coast.
1 Introduction
The intertidal brachyuran fauna of Iraq is not well known, although that of the surrounding areas of the
Arabian Gulf (=Persian Gulf) has generally been better studied (Jones, 1986; Al-Ghais and Cooper, 1996; Apel
and Türkay, 1999; Apel, 2001; Naderloo and Schubart, 2009; Naderloo and Türkay, 2009).
In comparison to other crustacean groups, brachyuran crabs have been well studied in the Arabian Gulf
(=Persian Gulf) (Stephensen, 1946; Apel, 2001; Titgen, 1982; Naderloo and Sari, 2007; Naderloo and Türkay,
2012). Brachyuran crab species of family Xanthidae are common inhabitant of tropical rocky shore (Ng et al.,
2008). The family Xanthidae is one of the most common families in the region. Apel (2001) listed 22 Xanthid
species from the Gulf, of which five were new records to the region. Naderloo and Türkay (2012) added
Macromedaeus voeltzkowi (Lenz, 1905) and two new species of Palapedia Ng, 1993, were recently described
by Naderloo (2015).
The aim of the present paper deals with new record for Iraq of A.roseus from fresh specimens collected
from NW of the Arabian Gulf at Faw region and to add A. roseusto the brachyura list of Iraqi waters.

2 Methods
The samples were collected from intertidal and shallow subtidal habitats around the Iraqi coast south Al-Faw,
Basrah, Iraq, by hand and trawl net (figure 1.). Some physico-chemical parameters recorded from the study
area during the collections made in January 2016 are: water temperature, 13.5°C; pH, 7.68; salinity, 36.7 psu;
dissolved oxygen, 7.82 mg/L. The specimens were preserved in 70% alcohol and shipped to the laboratory of
Marine biology, Marine science Center, University of Basrah (MSC).
The specimen was identified and described following Sere`ne (1984), Galil et al. (2002), Foka and
Papadopoulou (2010), and Naderloo et al. (2016).
Abbreviations used: CL. = Carapace length; CB. = Carapace breadth.
