Assessment of conservation status is a necessary step before management plans can be formulated. Historically such assessments have a strong bias toward vertebrates, particularly endothermic terrestrial vertebrates (i.e. birds and mammals). Invertebrates, by contrast, tend to be ignored, and many insect groups, despite being species rich and reasonably well studied, such as the Odonata (damselflies…
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 Previous unpublished records are provided for P. carnifex,…
The previously unknown larva of Argia jujuya Ris, 1913 is described, diagnosed and illustrated. Among other characters, the following combination is important to distinguish it from other species in the genus: antennae with six concolorous segments, ligula projected only slightly, row of small premental setae present, abdominal sternum 8 almost entirely covered with spiniform setae,…
Peristicta guarellae sp. nov. (holotype: Brazil, Paraná State, Exc. 399/col. 3, stream in km 50 of Curitiba-Ponta Grossa route [BR 376], about 25°20′08″ S, 49°51′15″ W, 21 November 1971, N. D. Santos leg., deposited in the Collection of “Museu Nacional, Universidade Federal do Rio de Janeiro”, Rio de Janeiro, Brazil) is described and illustrated. An
At a wetland in southeastern Mexico a female of Telebasis filiola was observed and photographed preying on a small web-building spider of the genus Leucauge. This is the first record of gleaning by a representative of the genus Telebasis. A brief discussion on this subject in other odonates is provided.
Although the sex ratio of Odonata at emergence has received much attention, we are still far from understanding the exact causes of its variability and imbalance. In this paper we studied the sex ratios at emergence in natural populations of two Gomphus species based on samples of exuviae taken from two European lowland rivers. We
