Four new species of Palaiargia from New Guinea, P. benkeni, P. clarillii, P. quandti and P. tydecksjuerging, are described and figured. Maps are provided of the known distributions of all species of the genus which occurs in the Moluccas and on the main island of New Guinea. Previous unpublished records are provided for P. carnifex,…
Coeliccia diehlae sp. n. (holotype male from Ko Roong Commune, Ka Bang District, Gia Lai Province, Central Highlands of Vietnam, deposited in the Zoological Collection of Duy Tan University) is described based on both sexes. This species belongs to the pyriformis-group and comes closest to…
Protosticta binhi sp. n. is described from the Central Highlands of Vietnam (holotype male: Vietnam, Gia Lai Province, K’Bang District, Dak Roong Commune, Dak Hro village, 14.36611° N, 108.4103° E, 1130 m asl, 22 May 2018, T.odo. 22051810, Zoological Collection of Duy Tan University). The new species can be easily distinguished from all other Protosticta…
Coeliccia schorri sp. n. is described based on both sexes (holotype male from Dak Roong Commune, K’bang district, Gia Lai province, central highlands of Vietnam). The combination of the characters of a large pruinose spot on the synthorax, blue abdominal tip, and white appendages in the male and a long spine on the posterior pronotal…
Burmagomphus schneideri sp. nov. (Rung Giong, Kanak commune, K’Bang district, 14° 8′42.05″ N, 108° 36′37.33″ E Gia Lai Province in the southern part of Vietnam, leg. Do, 27 iv 2010, to be deposited in Vietnam National Museum of Nature) is described from the male sex and compared with males of the closely related species B….
We analyse COI sequences of 48 specimens of European Lestes virens (Charpentier) to explore patterns in genetic diversity including subspecific boundaries and potential glacial refugia. Our haplotype network and phylogenetic analyses reveal three distinct groups in Western and Northern Europe.
Within wide geographical areas, Odonata populations can show biometric differences as a consequence of both biotic (e.g., predation, competition) and abiotic factors (mainly temperature). These differences can occur in the larval stage, although reliable characters are needed to detect differences.
Demography and territorial behavior of Hetaerina cruentata was studied along three lowland streams located at Norte de Santander department in the Colombian Andean region. Adult damselflies (N: 278) were individually marked, and using their recapture histories we estimated survival, longevity, sex ratio, age groups and population size at each location.
Forests have been widely recognized as key habitats for odonate (dragonflies and damselflies) biodiversity, but the importance of forests for holding odonate biodiversity remains understudied in tropical mountains, one of the most diverse ecosystems on the planet. Here we describe the odonate assemblage composition along the elevation gradient in the Tatamá Mountains (Colombian Cordillera Occidental).
The matrix, an environment in the landscape that individuals move through but do not reside in, can affect species dispersal and the arrival of individuals at habitat patches. Elements around this matrix that provide refuge or resources may shape the arrival of animals at habitat patches, even when those patches are equivalent in quality. Adult dragonflies (Odonata: Anisoptera) frequently use open terrestrial environments during movement and dispersal in north-temperate regions…
