The calopterygines Archineura incarnata and Atrocalopteryx melli are subtropical habitat specialists, endemic to China, and sensitive to environmental change. We identified several sites with environmental deterioration from which the species seem to have disappeared; these species can be used as indicators of human disturbance. In this paper their distribution in China is mapped and information…
Platycnemis doi sp. nov. (holotype ♂ Vietnam, Lang Son province, Huu Lien nature reserve, Tan Lai, Hang Chau, altitude 200 m above sea level, 22 June 2010, deposited in RMNH, Leiden), is described on the basis of a series of male specimens. A preliminary description of the female based on a photograph taken in the…
Although understanding of geographic range shifts of many species in response to global climate change is expanding steadily, little is known about the Himalayan fauna, which in particular is affected by relatively faster warming rates than other parts of the world. Anticipated increases in temperature and changes in hydrological regimes will have significant adverse impacts…
The levis and ferruginea groups of Orthemis are redefined. Six new species of Orthemis are described: O. aciculata sp. nov. (♂ holotype: Surinam, Para Dist., road near forest, Zanderij I (5°32′ N, 55°10′ W), 17 January 1957, leg. J. Belle [RMNH]), O. celata sp. nov. (♂ holotype: Brazil, Pará State, Rio Gurupí, Canindé (0°30′57′ ′…
Lanthanusa bilineata, a new libellulid from the mountains of central New Guinea (holotype: Mekil Research Station (04°48′ S, 141°39′ E), leg. 1 September 2004, dep. at RMNH, Leiden), is described. The new species combines characteristics previously used to distinguish between Huonia and Lanthanusa with wing venation characteristic of the genus Huonia and accessory genitalia characteristic…
Macromidia donaldi pethiyagodai subsp. nov. (holotype ♂: Sri Lanka, Ratnapura District, near Kudawe, 6.26°N, 80.25°E, 03 July 2007; paratype ♀, same location, 17 April 2008, to be deposited in the Sri Lanka National Museum, Colombo) is described and figured. Its phenotype differs from that of M. d. donaldi from India. This is the first record…
The last instar larva of Calopteryx exul Sélys is described and illustrated based on larvae collected from the Seybouse River (northeast Algeria) and reared in the laboratory. A comparative analysis of three other congeneric species is presented.
A new species, Leptagrion cyanostigma sp. nov., is described and illustrated based on 1 ♂ and 1 ♀ collected in the State of Bahia, Brazil. The species is generically unique by having a blue pterostigma with a black center. A survey of other Zygoptera possessing blue pterostigmata is carried out.
Two new species of Metaleptobasis from Ecuador are described and illustrated. Metaleptobasis gibbosa (holotype ♂, allotype \female: Ecuador, Pastaza Province, forest wetlands, Los Copales, between Mera and Shell, 01° 29′ 30′′ S, 078° 04′ 19′′ W, elevation 1070 m, 20–22 September 2005, leg. K. J. Tennessen; deposited in Florida State Collection of Arthropods) appears related…
Clutch size is an important fitness component often quantified artificially by inducing oviposition in libellulid females. Female behavior and egg production of the yellow-veined skimmer, Orthetrum nitidinerve, were studied in northeast Algeria during its reproductive season. Data on reproductive behavior and biology of this Mediterranean endemic species has not been published previously. Males guarded territories…
