Material examined. Holotype and paratypes ( Giłka 2009a ). UNITED ARAB EMIRATES . Al Wathba Wetland Reserve ( AWWR ), October 2014, 1 male , June 2015, 1 male, Malaise traps , leg. A. Saji & A. van Harten. Deposit in DIZP. Remarks. Adult males of this peculiar species have an extremely elongated, sagittate and darkly pigmented hypopygial anal point lacking crests and spinulae ( Giłka 2009a, figs 13, 14 ). Cladotanytarsus sagittifer has so far been known from three sites in the United Arab Emirates . The present record comes from the Al Wathba Wetland Reserve ( 40 km SE of Abu Dhabi ) - one of the most important inland wetlands in the UAE , waterlogged during the winter months, presumably the result of sub-surface flow and hydrostatic back-up during spring high tides ( Soorae et al . 2014 ).
