This paper presents a review of published records and voucher specimens in museum collectons. We reviewed 39 references and identfed 116 records concerning nine species belonging to fve families. Fifeen of these records menton 71 specimens of six species in collectons. Distributon maps of known locatons are provided for each species. Most records (70%) date back more than 10 years and two species have not been recorded for more than 40 years. Based on the bat fauna of Oman, a more thoroughly investgated neighbouring country, the presence of at least nine other, stll unrecorded, species is expected. The status of bats in UAE and their conservaton concerns are discussed. We encourage further feld studies of the bat fauna of UAE. Keywords: Distributon, literature review, museum specimens, UAE.

INTRODUCTION provided by authors. Species distributons were mapped, distnguishing locatons already considered by Rare are the reports of naturalists’ observatons Harrison & Bates (1991) from newer locatons, collected and wildlife records in the United Arab Emirates before in the last 25 years (Fig. 1.). The main natural history the 1950s. Only a few foreign early travellers took museums holding a bat collecton have been approached note of the most notceable fauna and fora species or to inquire about their possession of specimens from initated some wildlife specimen collecton (Thomas UAE. Voucher specimens collected from UAE are 1932; Thesiger 1959). Only in the mid 20th century, the preserved or deposited in the Harrison Insttute (HZM) fauna of the territory that would become the United - Sevenoaks, United Kingdom; Natural History Museum Arab Emirates in 1971, began to receive atenton from (BMNH) - London, United Kingdom; Zoologisches foreign expatriates or visitors. Bats were no excepton, Forschungsmuseum Alexander Koenig (ZFMK) - Bonn, but even today, have stll received very litle atenton, Germany; Hungarian Natural History Museum (HNHM) presumably in relaton to their cryptc life, difcultes - Budapest, Hungary. References of museum specimens of feld investgatons, and the apparent low species were obtained from literature (Harrison 1964; Harrison diversity and abundance compared to other parts of & Bates 1991; van Cakenberghe & de Vree 1994) or the world. Most knowledge on bat species diversity communicated by the HNHM. comes from the surveys conducted by David Harrison in The taxonomic nomenclature used follows Wilson 1953–1955 and 1975 (Harrison & Bates 1991; Harrison & Reeder (2005) with the excepton of Rhyneptesicus 1955). Only few additonal records have been published nasutus afer the revision of Juste et al. (2012). in the following decades and only the Partcolored Bat Vespertlio murinus has been lately added to the species list of bat fauna established by Harrison (Monadjem et RESULTS al. 2016). Despite growing concern for environmental The review of published observatons and specimens conservaton in natonal insttutons, the consequences in collectons allowed the identfcaton of 116 records of economic development on wildlife populatons are concerning nine species (Table 1). Of these, 60 stll either not recognized or under-estmated. Field (51%) were original records; all others being quotes surveys data, well-designed long-term populaton or repettons of previously published records. For monitoring programmes and a centralized biodiversity example, six publicatons mentoning the presence database at the country scale are stll largely defcient. of Triaenops persicus in UAE (Harrison & Bates 1991; Given the data scarcity on the bat fauna of UAE, their Duckworth 1996; Aspinall et al. 2005; Drew et al. 2005; populaton status and trends, how they are impacted AGEDI 2008; Tourenq et al. 2009), cite the same single by environmental changes is unknown. Bat species original record represented by eight voucher specimens diversity might even be greater than currently assessed. (Harrison 1955). Among the 117 records, 15 referred to 71 specimens of six species that are kept in museum collectons. Of the 60 original records, 42 (70%) dated MATERIAL AND METHODS more than 10 years back with an average of 7.5±6.7 records per 10 years (n=8) since the 1940s. This review We reviewed museum specimens and published brings an additon of 43 new records (Table 1) to the records (including journals, artcles, books and internet synthesis published by Harrison & Bates (1991). pages) to collect species occurrences, map distributons, highlight the gap in data, and stmulate further feld List of species investgatons in order to beter assess the conservaton Egyptan Rousete Rousetus aegyptacus status of the species concerned. We considered as a (E. Geofroy, 1810) record every menton of a species per site. Informaton A total of 13 original records of the Egyptan Fruit Bat on the sites and period of collecton of museum (Image 1) in UAE have been published.
