A06C8793FF8F6B45FF50FB78FEF3FF67.taxon	description	Variation. The third article of accessory flagellum in some specimens was vestigial. In material examined the protuberance and dentate along palm of second male gnathopod was varied from markedly and quadrate dentate to vestigial protuberance. The hump on first urosomite was different from triangle specified to vestigial hump. Also in the outer ramus of third uropod has been shown different number of apical setae.	en	Momtazi, Farzaneh, Sari, Alireza, Maghsoudlou, Abdolvahab (2014): New species and new record of hadzioids (Amphipoda: Senticaudata, Hadzioidea) from the Persian Gulf, Iran.

A06C8793FF8F6B45FF50FB78FEF3FF67.taxon	discussion	Remarks. Elasmopus menurte Barnard, 1974 is a new member of the genus Elasmopus in the Persian Gulf. Previously, Jones (1986) and Salman (1998) reported E. pectenicrus from the Persian Gulf. The genus Elasmopus has more than 100 described species. Elasmopus menurte Barnard, 1974 is similar to E. japonicus Stephensen, 1932, and E. woodjonesi Hughes & Lowry, 2011 in having a dorsal hump on the first urosomite (Vader & Krapp- Schickel 2012). However the specific characters on second male gnathopod differentiate E. menurte from E. woodjonesi. There are more similarities between E. menurte and E. japonicus in the second male gnathopod as Barnard (1974) believed that E. menurte and E. japonicus Stephensen (1932) differ only at subspecific status. Based on Barnard (1974) E. menurte differs from E. japonicus in the much lower crest of urosomite 1 and in telson characters. The type locality of E. menurte is the south coast of Western Australia. Other records belong to the north coast of Western Australia (Hughes & Lowry 2011) and Mauritius (Appadoo & Steele 1998; Appadoo & Myers 2003). There was some differences between descriptions of Australian (Barnard 1974), Mauritian (Appadoo & Myers, 2003) and Persian Gulf material. Mainly differences were in the first male gnathopod and mandibular palp. However, carpus length in the first male gnathopod was equal to propodus in studied material; it was slightly longer in Australian specimens and shorter than the propodus in Mauritian specimens. The Persian Gulf materials were specified by some stout setae on the third article of the second antennae and the shorter length of the first article of the mandibular palp that is less than half of the second article whereas in the Australian and Mauritian materials it exceeds 0.6 times the second article. Unlike the distinct serration on the posterior margin of the epimera in the Persian Gulf material, it is not mentioned in descriptions of E. menurte by Barnard (1974) and Appadoo & Myers (2003). However, Vader and Krapp-Schickel (2012) assigned it in the matrix of Elasmopus species characters.	en	Momtazi, Farzaneh, Sari, Alireza, Maghsoudlou, Abdolvahab (2014): New species and new record of hadzioids (Amphipoda: Senticaudata, Hadzioidea) from the Persian Gulf, Iran.

A06C8793FF8D6B4DFF50FE6FFE0DFD8F.taxon	discussion	Remarks. Melita persia sp. nov. is an abundant amphipod along the coast of Qeshm Island, in the Persian Gulf. Melita persia belongs to the Melita zeylanica group, that is defined by morphologically similar species of Melita with 1 - articulate outer ramus on the third uropod (Appadoo & Myers 2005). The Melita zeylanica group is comprised of M. corticis Appadoo & Myers, 2005, M. persia sp. nov, M. setiflagella Yamato, 1988, M. zeylanica Stebbing, 1904 and M. zeylanica kauerti Barnard 1972. Between the members of this group M. persia is more close to Melita zeylanica kauerti Barnard, 1972 based on similar characters on the urosomites, first antenna, curved sixth coxa on females and bearing more than one stout seta on inner ramus of the third uropod. Differences between species of this group were shown on Table 1. The proximal lobe of the female coxa 6 shows different degree of curvature in this group (Fig. 8). Melita persia has the most highly curved anterior lobe on coxa 6 of known female Melita. Other species level characters that could be distinguished M. persia from other members of Melita zeylanica group were a submedial robust setae along outer margin of telson, the presence of two robust setae on inner ramus of uropod 3 and the presence of marginal setae on both sides of the third article of the mandibular palp (see Table 1, for more details).	en	Momtazi, Farzaneh, Sari, Alireza, Maghsoudlou, Abdolvahab (2014): New species and new record of hadzioids (Amphipoda: Senticaudata, Hadzioidea) from the Persian Gulf, Iran.
