Abstracts of Papers presented at the Mnais Symposium, Kyoto, Japan, January 5-6, 1980

The Japanese Mnais damselflies (Odonata: Calopterygidae) are treated as a single species. M. pruinosa Selys, composed of three subspecies with eleven forms (S. ASAHINA. 1976. Tomhu 19: 2-16; cf. Tab. I). The ranges of two subspecies, however, are largely sympatric and show a number of different features in their reproductive behaviour. Thus, studies on Mnais have become attractive to both academic researchers and many amateur workers. Some have worked in the field of taxonomy with reference to distribution, others in the field of ecology, with reference to behaviour In addition, the latter workers have studied each population in each locality. The Symposium was held at the Kyodai Kaikan (host T. UEDA) with the objective that discussions should mutually inspire the Mnais workers.
