Abstract

This paper is dedicated to Philip S. Corbet on the occasion of his 70th birthday. Abstract Seventy-six species of Odonata are recorded from Dinghu Shan Biosphere Reserve, Guangdong Province, China, following surveys completed during 1992-1998. Anew species of Cephalaeschna (Aeshnidae) and a new species of Philosina (Megapodagrionidae) are described and illustrated. The previously unknown female of Stylurus nanningensis Liu (Gomphidae) is also described. Asiagomphus septimus (not of Needham) from Hong Kong is synonymised with Asiagomphus hainanensis Chao. Aciagrion tillyardi Laidlaw (Coenagrionidae) is recorded from Chinese Territory for the first time. Zygonyx takasago Asahina (Libellulidae) previously considered a Taiwanese endemic, is recorded from continental China. A key is provided to separate the three Chinese species of Zygonyx.A total of twenty-eight taxa are recorded from Guangdong Province for the first time. The odonate fauna of Dinghu Shan is compared with neighbouring Hong Kong and Taiwan. © 1999 Taylor & Francis Group, LLC.
