Caloptera damselflies from Fujian (China), with description of a new species and taxonomic notes (Zygoptera: Calopterygoidea)

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: Caliphaea nitens Navas, 1934 is removed from synonymy with Bayadera melanopteryx 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 B. brevicauda Fraser, 1928 from Taiwan. Bayadera 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.
