Dysphaea haomiao sp. nov. from China and Vietnam (Odonata: Euphaeidae)

Dysphaea haomiao sp. nov. (holotype ♂, China, Guizhou, Libo County, Xiaoqikong Scenic Area, Zhangjiang River, alt. c.450 m, 7 May 2007) is described and illustrated for both sexes. The male differs from its closest congeners, Dysphaea basitincta and D. gloriosa, by the blackish, completely opaque coloration of its wings.

Epallagidae versus Euphaeidae revisited

The author’s previous rejection of Selys’ legions as available family-group taxa is restated and elaborated, strictly based on the provisions of the International Rules of Zoological Nomenclature (4th ed.).

Odonata fauna of Sri Lanka: research state and threat status

Altogether 116 odonate species are known from Sri Lanka. The level of endemism is high -53 taxa or 45.7% are confined to the island. The Chlorocyphidae, Euphaeidae, Protoneuridae, Platystictidae, Gomphidae and Corduliidae consist of almost exclusively endemic taxa. The odonate fauna of Sri Lanka is still insufficiently known. Knowledge on distribution, biology and taxonomy of…

Tandem grip mechanics and tandem linkage shifting in Odonata – reconstruction of evolution and phylogenetic significance

The functional morphology of the male caudal clasping apparatus of Zygoptera is compared to that of Epiophlebia superstes (Anisozygoptera) and Anisoptera. Hypotheses concerning the mechanics and muscle functions have been advanced by parallel construction of mechanical working models. The evolution of the clasping apparatus and the tandem linkage shifting – from the female pronotum to…

New fossil damselflies from Baltic Amber, with description of a new species, a redescription of Litheuphaea carpenteri Fraser, and a discussion on the phylogeny of Epallagidae (Zygotera: Caloptera)

Litheuphaea ludwigi sp. n. is described as first representative of Epallagidae from Baltic amber. The holotype of Litheuphaea carpenteri Fraser, 1955 is redescribed, the phylogenetic position of all fossil Epallagidae is discussed, and a new phylogenetic classification is proposed. The authorship of Selys (1853) for the family-group name Euphaeidae is rejected, since the “légion Euphaea”…
