Dumont, H. J. Distinguishing between the East-Asiatic representatives of Paracercion Weekers & Dumont (Zygoptera: Coenagrionidae) p. 361-370. Eight species occurring in Japan and continental East Asia are separated by the morphology of their male terminalia and by the structure of the female pronotum and adjacent laminae mesostigmales. Paracercion barbanan is confirmed as a good species, probably restricted to China, where it co-occurs with P. impar and other spp. The continental East Asian P. v-nigrum is suggested to share a common ancestor with the Japanese P. sieboldii. On chorological grounds, the latter should not exist in Taiwan. Both sexes of all spp. are keyed.

Hamalainen, M. Caloptera damselflies from Fujian (China), with description of a new species and taxonomic notes (Zygoptera: Calopterygoidea) p. 371-398. Based on literature records and the examination of an extensive Odonata collection made in Fujian in 1930-1940's (now in RMNH, Leiden), 21 spp. of Caloptera (Calopterygoidea) are recognized as occurring in Fujian province in eastern China. The Fujian Caloptera material (ca 860 specimens of 18 species) in RMNH is enumerated. The following taxonomic decisions are presented: Navas, 1934 is removed from synonymy with Caliphaea nitensBayadera melanoptetyx Ris, 1912 and ranked as a valid species, distinct from C. consimilis McLachlan, 1894. The lectotype of Vestalis smaragdina Selys, 1879 is designated. Vestalis velata Ris, 1912 (syn. V. virens Needham, 1930) is ranked as a good species, while the "hyaline winged form of V. smaragdina velata" (sensu Asahina, 1977) is described as a new sp. Vestalis venusta sp. n. Bayadera continentalis Asahina, 1973 from Fujian and B. ishigakiana Asahina, 1964 from the Ryukyus are treated as full sp. and not as ssp. of Fraser, 1928 from Taiwan. B. brevicaudaBayadera melania Navas, 1934 is synonymized with B. melanopteryx Ris, 1912. Some preliminary taxonomic comments (to be discussed in detail elsewhere) are presented: Calopteryx grandaeva Selys, 1853 is a probable synonym of C atrata Selys, 1853, whereas C. atrocyana (Fraser, 1935) is a good sp. Matrona basilaris Selys, 1853 and M. nigripectus Selys, 1879 appear to be distinct sp. Mnais tenuis Oguma, 1913 and M. andersoni McLachlan in Selys, 1873 are also better treated as separate sp. Faunistic notes include: Libellago lineata (Burmeister, 1839) is recorded from Fujian province for the first time. Old records of Psolodesmus mandarinus McLachlan, 1870 and Euphaea compar McLachlan, 1870 (synonym of E. formosa Hagen in Selys, 1869) from Amoy Island near the Fujian coast are considered doubtful.

Hayashi, F.; Dobata, S.; Futahashi, R. Macro- and microscale distribution patterns of two closely related Japanese Mnais species inferred from nuclear ribosomal DNA, its sequences and morphology (Zygoptera: Calopterygidae) p. 399-412. Much variation occurs in morphology and colouration among individuals of Japanese Mnais spp. It has been noted that 2 groups of Mnais often cohabit a stream in western Japan. There is, however, no clear morphological difference in male appendages and penis between the 2 groups, and this makes it difficult to determine their taxonomic status. In this study, to clarify the relationships between the sympatric species on both small (along a stream) and large (across Japan) geographic scales, sequences of the internal transcribed spacers 1 and 2 (ITS 1 and 2) of nuclear ribosomal DNA are compared. Base substitutions occurred at 4 sites of 223 bps of the ITS1 region, and by their combinations, the four sequence types could be distinguished among a total of 800 individuals. In the ITS2 region (total 411 bps including 5.8S rRNA region), all examined individuals had the same sequence. The geographical distribution of each ITS1 sequence type and morphological data of wings and a pterostigma suggest that Japanese Mnais includes 2 distinct spp., M. strigata Selys, 1853 and M. costalis Selys, 1869. Their distribution ranges overlap widely in western Japan, where M. strigata is usually found at smaller and upper streams than M. costalis.

Theischinger, G. Affinities and status of some genus-group taxa in Australian Gomphidae (Anisoptera) p. 413-421. Relevant and mainly structural characters of Austrogomphus s. str., Austroepigomphus Fraser, Pleiogomphus Watson, Xerogomphus Watson and Zephyrogomphus Watson, all considered by J.A.L. WATSON (1991, Invertebr. Taxon. 5: 289-441) as subgenera of Austrogomphus Selys, are described and illustrated. On the basis of this information it is suggested that Austroepigomphus and Zophyrogomphus should be elevated to generic rank, that Pleiogomphus should keep its position as a subgenus of Austrogomphus, and that Xerogomphus should be regarded as a subgenus of Austroepigomphus. Some morphological details of the previously undescibed male of what is now Zephyrogomphus longipositor (Watson) are given.

Wilson, K. D. P. New Odonata from South China p. 423-432. RhinocyPha chaoi sp. n. (holotype male Dadingshan, Guangdong), Megalestes discus sp. n. (holotype male: Mangshan, Hunan). Rhipidolestes chaoi sp. n. (holotype male: Mangshan, Hunan), Calicnemia chaoi sp. n. (holotype male: Pengshan, Guangdong) and Macronlia unca sp. n. (holotype male: Maoping, Guangdong) are described from the Shikengkong area of northern Guangdong province and Southern Hunan ill Southern China.

Karube, H. Heliogomphus chaoi spec. nov., a new dragonfly from southern Vietnam (Anisoptera: Gomphidae) p. 433-436. The new sp. is described, illustrated and compared with the similar H. selysii Fraser. Holotype male: S Vietnam, Laindong prov., 15 km from Bao Lok to Ho-chi-minh, 6-V-1997; deposited in Kanagawa Prefectural Museum of Natural History, Odawara, Japan.

Lin, Q.; Zhang, S.; Huang, D. Fuxiaeschna hsiufunia gen. nov., spec. nov., a new Lower Cretaceous dragonfly from northwestern China (Aeshnoptera: Rudiaeschnidae) p. 437-442. The new gen. and sp. are described and illustrated from the Luohandong Formation of Huating Co., Gansu province, P.R. China, from a single, almost complete specimen. Holotype No. 123518, probably a female, deposited at IGPAS, Nanjing, China.

Samways, M. J. Monopodding in Lestinogomphus angustus Martin (Anisoptera:Gompihdae) p. 443-444. The long abdominal segment 10 in L. angustus is used as a monopod to support itself while it perches on horizontal steins and twigs in the shade of bushes or trees.
