A new species of Protosticta Selys, 1885 is described based on specimens collected from Kerala, northeast of Thiruvananthapuram, in the southern parts of the southern Western Ghats of India.
The traditional method of classifying the twenty-one species within the South American genus Polythore has been relying on wing color patterns and male genital ligula shape. However, recent molecular research has shown that wing color patterns can vary significantly within some species, making it an insufficient means of species diagnosis by itself in some cases.
Tukanobasis huamantincoae sp. n. (holotype ♂: Peru, Loreto Región [MUSM]) is described and illustrated. Males of T. huamantincoae can be distinguished from T. corbeti by the presence of postocular spots and antehumeral stripes, the absence of apical brown wingspots, smaller number of postnodals, shorter CuA, …
The taxonomy and distribution of dragonflies of the genus Heliogomphus from the Western Ghats of southern India are discussed. A morphological study of fresh male specimens from the field, as well as holotypes and lectotypes from repositories was undertaken.
The larva of Cordulegaster vanbrinkae Lohmann, 1993 is described and illustrated based on fourteen final instar larvae and 49 exuviae that were collected in Gīlān, Māzandarān and Golestān provinces, in northern Iran in July 2014, July 2017 and August 2018.
The final instar larvae of the two species of the southern African gomphid genus Ceratogomphus, the South African endemic C. triceraticus and the more widespread C. pictus, are compared based on exuviae. Main differences are the shapes of the prementum and of the last abdominal segments, giving C. pictus a more slender and pointed appearance.
Despite the important role of the order Odonata in ecosystems, there is a lack of information about dragonfly communities in several regions, high elevation sites, and environmentally protected areas in Minas Gerais State, Brazil. Our objective was to assess the abundance and richness of dragonfly and damselfly communities along an elevational gradient in the Atlantic Forest, southeastern Brazil.
The Indian Elattoneura are a difficult group to identify due to their extreme morphological similarity and sparse information in identification keys and on geographical distribution. The ambiguity is prominent among two Peninsular Indian Elattoneura species, E. nigerrima (Laidlaw, 1917) and E. tetrica (Laidlaw, 1917), described a hundred years ago.
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…
Within the damselfly subfamily Platycnemidinae, eight species are currently recognized in South-East Asia. The final stadium larvae of only three of them have been so far described. The final stadium larva of Copera chantaburii is described and illustrated for the first time, based on reared specimens, and new provincial records both of larvae and adults…
