All the holotypes are deposited in the Collection of Aquatic Animals, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan City, Hubei Province, China. Brief notes on biology of…
Three new Cephalaeschna species, C. discolor sp. nov. (holotype male; Shennongjia National Nature Reserve, Shennongjia City, Hubei province, China, 16 August 2012), C. mattii sp. nov. (holotype male; Lujiahe River, Zigui County, Hubei province, China, 18 September 2012) and C. solitaria sp. nov. (holotype male; Dalongtan in Shennongjia National Nature Reserve, Shennongjia City, Hubei province,…
The final larval stadium of four species of Cora are described and compared with known species in the genus. Cora skinneri Calvert, 1907, C. semiopaca Selys, 1878 and C. lugubris Navás, 1934 are described and illustrated for the first time using material from Costa Rica for the first two and from Colombia for the latter….
Pseudagrion lorenzi sp. nov. is described from New Britain island, Papua New Guinea. Male and female characters are illustrated by means of scanning electron microscopy. A differential diagnosis with Pseudagrion civicum Lieftinck, 1932 from New Guinea and Pseudagrion incisurum Lieftinck, 1949 from the Solomon Archipelago is provided. The female of P. incisurum is described for…
Risiocnemis corbeti sp. nov. and R. hamaiaineni sp. nov. (for both species: holotype ♂, Dipinantahikan area [16°53′39″N, 122°20′47″E], Dipagsangaan, Palanan, Isabela, Luzon, Philippines, 12-20 ix 2008, in RMNH) are described, illustrated, and diagnosed.
Elasmothemis rufa sp. nov. (holotype: Venezuela, Amazonas, Río Cataniapo), Macrotbemis taurepan sp. nov. (holotype: Venezuela, Bolívar, El Paují), and Oligoclada garrisoni sp. nov. (holotype: Venezuela: Amazonas, San Fernando de Atabapo) are described and illustrated. All holotypes are deposited at MIZA. Macrothemis heteronycha and Micrathyria paruensis are recorded from Venezuela for the first time, and Micrathyria…
Neurobasis awamena, a new calopterygid species from the southern highlands of New Guinea (holotype: Pimaga area, 6°30′S, 143°30′E, 27 vii 1994, deposited at Naturalis, Leiden) is described and figured. It is distinguished from the widespread N. australis by its longer legs, irregular teeth on the male cerci, and the sharp demarcation of the iridescent color…
The Afrotropical ‘neodythemistine’ genera are an example of venation-biased classification in Odonata. This example is used to argue the bankruptcy of some traditional classifications in the order, particularly in the Libellulidae, and the need to apply alternative characters to define genera. Two groups of Afrotropical ‘neodythemistines’ are identified by male and female genitalia, supported by…
