Studies On Classification Of Fujian Odonates, China

All the odonate specimens collected from Fujian Province in recent years were studied and identified. 1 new species and 1 new subspecies were described and illustrated, and 14 species were firstly recorded in Fujian. The new species and new subspecies are Periaeschna zhangzhouensis sp.nov. and Planaeschna ishigakiana fujianensis subsp. nov. The newly recorded species are: Rhinocypha chaoi Wilson, Agriomorpha fusca May, Rhipidolestes janetae Wilson, Aciagrion olympicum Laidlaw, Platycnemis foliacea Selys, Anax immaculifrons Rambur, Lamelligomphus hainanensis (Chao), Merogomphus paviei Martin, Phaenandrogomphus chaoi Zhu et Liang, Stylurus kreyenbergi (Ris), Macromia unca Wilson, Macromidia hangzhouensis Zhou et Wei, Onychothemis testacea tonkinensis Martin and Zygonyx iris insignis (Kirby). Based on all the literature records of Fujian odonates and Davies and Tobin system (1984,1985) of Odonata classification, Fujian odonates were sorted out and revised thoroughly, 16 families, 102 genera and 247 species (subspecies) were found, which included 233 known species (or subspecies) belonging to 101 genera, 16 families. In the checklist of Fujian odonates, every species was enumerated with relative literature records, amounts of specimens, collected locations and collected times, and distribution. Based on the current methods of entomo-geographical division and the distribution records of 233 known odonates, the faunal analysis of Fujian odonates was conducted. The result showed that the fauna of Fujian odonates belongs to typical Oriental Region, the elements of Oriental Region of Fujian odonate fauna are dominated by the constituents of Southern Chinese origin. The faunal compositions of Fujian odonates reflect the region characteristics which are obviously discrepant between South-Eastern Fujian and North-Central Fujian which were divided according to entomo-geographical division of agriculture and forestry in Fujian. The gomphid dragonflies of Fujian have an obvious tendency to spread outwards from Indo-Chinese Subregion, which seems to be a center of abundance of the gomphid dragonfly fauna.
