Among them, one species belong to Abroma StSl: Abroma reducta (Jacobi, 1902), two species belong to Lemuriana Distant: Lemuriana apicalis (Xjermar, 1830) and L. vinhcuuensis Pham & Yang, 2010, and two belong to Hea Distant: Hea fasciata Distant, 1906, H. yunnanensis Chou et Yao, 1995. L. vinhcuuensis Pham & Yang is known only from Vietnam. A key to genera and species of Taphurini from Vietnam based on the male adults is also given. A map with collection localities and data of examined material are provided. Key words: Cicadas, key identification, morphology, distribution. INTRODUCTION There are 31 genera belonging to tribe Taphurini, subfamily Cicadettinae, family Cicadidae in the world. They are distributed in all faunal regions except the poorly represented in the Palaearctic. The first record species of the tribe Taphurini in Vietnam was made by Jacobi in 1902 with the species Abroma reducta (Jacobi, 1902). In 1917, Distant recorded the second species Lemuriana apicalis Distant, 1917. Pham and Yang (2009) recently recorded two more species Hea fasciata Distant, 1906 and Hea yunnanensis Chou et Yao, 1995). In 2010, Pham & Yang described a new species Lemuriana vinhcuuensis Pham & Yang. This is the fifth species ofthe tribe Taphurini. MATERIAL AND METHODS Specimens were collected by netting and light trapping at the localities indicated in the item of material examined. Previously collected specimens were included in our evaluations. Specimens are deposited at the Department of Insect Systematics of the Institute of Ecology and Biological Resources, Hanoi, and the Museum National d'Histoire Naturelle, Paris. The tribal classification of this study is based mainly on that of Moulds (2005). Genus and species names, as well as synonymies, follow the catalogues of Metcalf (1963), and Lee (2008). 261 HQI NGHI CON TRONG HQC QUOC GIA LAN THif 7 - HA NQI 2011 Specimens examined are listed by provinces (given in bold). Abbreviations are as follows: lEBR (Institute of Ecology and Biological Resources), MNHN (Museum National d'Histoire Nsiturelle, Paris), NP (National Park), NR (Natural Reserve). The map showing the collecting localities for this study was created using the software CFF (Barbier & Rasmont, 2000). Taxonomy Family Cicadidae Latrielle Subfamily Cicadettinae Buckton Tribe Taphurini Distant, 1905 Taphuraria Distant, 1905: 25. Lemuriaria Moulton, 1923: 78. Eaphurarini [sic] Lallemand, 1925: 2. Taphurini Kato, 1932: 171. Type genus. Taphura Distant (type species T. misella Stal). Remark. Males differ from other members of the subfamily Cicadettinae by having the aedeagal basal plate with the ventral rib rod - like, suspended with attachments only at ends. The claspers are widely separated except in Abricta occidentalis that represents a new genus. Males can be distinguished from those of the Cicadettini by having the timbals not extending below the level ofthe wing bases, and the timbal ribs are long and closely spaced and at least 5 in number. Females differ from the Chlorocystini and Prasiini by having the head broader than the maximum width ofthe pronotum. Females cannot be distinguished from those of the Cicadettini in which the fore wing veins M and CnA meet the basal cell separated (Moulds, 2005).
