Esperança, s/n, 74690-900, Goiânia, Goiás, Brazil ABSTRACT A new species of telescope shrimp, Ogyrides sindibadi sp. nov. is described from Kuwait. The new species is morphologically similar to O. striaticauda Kemp, 1915, originally described from Chilka Lake (India), but can be distinguished by the shape of the scaphocerite, the much longer dactylus of the third pereiopod, as well as the shape of the distal margin of the telson. ZUSAMMENFASSUNG Eine neue Art von Teleskop-Garnele, Ogyrides sindibadi sp. nov., ist aufgrund des in Kuwait gesammelten Materials beschrieben. Die neue Art ist morfologisch O. striaticauda Kemp, 1915, die aus Chilka Lake (Indien) beschrieben wurde, sehr ähnlich, unterscheidet sich jedoch von dieser Art in der Form des Antennenschuppe und des Hinterrandes des Telsons, sowie durch die längere Klaue des dritten Pereopoden. INTRODUCTION The telescope shrimp genus Ogyrides Stebbing, 1914 is the sole genus in the family Ogyrididae and currently comprises a mere 11 species worldwide, distributed in tropical to temperate waters. In the Atlantic Ocean, two species are known from the western Atlantic, O. alphaerostris (Kingsley, 1880) and O. hayi Williams, 1981, whilst one species, O. rarispina Holthuis, 1951 is known from the tropical eastern Atlantic.

Two species are known from the eastern Pacific, O. tarazonai Wicksten & Mendez, 1988 and O. wickstenae Ayón-Parente & Salgado-Barragán, 2013, with additional, probably erroneous records of the western Atlantic O. alphaerostris (Wicksten, 1983; Carvacho & Olson, 1984; Hendrickx & Wicksten, 1987). In the Pacific Ocean, three species are known with certainty only from geo- graphically restricted areas, although for several species records exist far beyond these areas, all of which require confirmation. Ogyrides delli Yaldwyn, 1971 is known from temperate New Zealand and south-eastern Australia (Banner & Ban- ner, 1982), O. striaticauda Kemp, 1915 from Chilka Lake, Cochin and Ennur back- waters in India (Kemp, 1915) and O. saldanhae Barnard, 1947 from temperate South Africa. A further species, O. mjoebergi (Balss, 1921), is known from several disjunct areas, the type material from Cape Jaubert in Western Australia (Balss, 1921), Northern Territory (Bruce & Coombes, 1997), Madagascar (Ledoyer, 1969, 1970), as well as the Mediterranean Sea in the temperate Atlantic, where it is con- sidered to be a Lessepsian migrant (Holthuis & Gottlieb, 1958). However, the true taxonomic status of the Mediterranean records (Galil et al., 2015) needs clarifica- tion. Two further nominal species are known from the Indo-Pacific, O. orientalis (Stimpson, 1860) and O. sibogae (De Man, 1910), the taxonomic status of which is somewhat confused. Although Fujino & Miyake (1970) consider both taxa to be synonyms, Bruce (1990) highlighted the fact that the holotype of O. sibogae was collected from a depth of purportedly 535 m and is unlikely to be a synonym of O. orientalis. With the amount of morphological (and ecological) variation in the material studied by De Man (1910, 1911, 1915, 1922) and assigned to his species, this is also indicative that more than one species could be involved. De Grave & Fransen (2011) followed suit and listed both taxa as currently accepted species. A contrasting view was held by Banner & Banner (1982), who indicated the possibility (without proposing a formal synonymy) that O. sibogae, O. mjoebergi and O. delli could all be synonyms of O. orientalis. This, however, seems unlikely given the morphological disparity of material reported under the names O. orientalis (e.g., Yokoya, 1927; Bruce, 1990) and O. sibogae (e.g., De Man, 1910, 1911). It appears more likely that several more species of Ogyrides await description. Irrespective of possible synonymies, O. orientalis is currently considered to be the most widespread species of the genus in the Indo-Pacific, with modern records from southern Korea (Kim, 1977), northern China (An et al., 2015), Fukushima, Japan (Yokoya, 1927), the East China Sea (Fujino & Miyake, 1970), Hong Kong (Bruce, 1990), Singapore (Anker & De Grave, 2016) and Pakistan (Tirmizi, 1980).

Despite the extensive taxonomic confusion in the genus, we report herein a new species of Ogyrides from Kuwait, which differs in several morphological characters from all other species currently known in the genus. Type material is deposited in the Zoological Collections of the Oxford Univer- sity Museum of Natural History, OUMNH.ZC). Post-orbital carapace length (pocl) was measured from the posterior margin of the orbit to the posterior margin of the carapace.
