The aim of this project was to obtain a baseline understanding and investigate the concentration of mercury (Hg) in the tissue of terrestrial arthropods. The 4-month sampling campaign took place around Monterey Bay, California. Total mercury (HgT) concentrations (x ± SD, dry weight) for the captured specimens ranged from 22 to 188 ng g(-1) in the Jerusalem crickets (Orthoptera: Stenopelmatidae)...

Risiophlebia guentheri sp. nov. (holotype: Cambodia, Mondulkiri Province, Dak Dam village environs, a tall grass forest swamp, 12°25' N 107°19' E, ~780 m a.s.l., 16 June 2014, RMNH), the second species in its genus, is described from Central Plateau of the Annamese Mountains. The new species is most probably separated from R. dohrni by a 1000-km gap of the range of the genus in Thailand and mos...

In total 20 species of aquatic insects have been recorded from a weed infested pond. Odonata was numerically the most abundant group constituting of 54% of the total aquatic insects even though these belonged to three species. Coleoptera though constituted only 22% of aquatic insects had 10 species. Urothemis signata and Ranatra filliformes were eudominant and dominant species respectively. Hyd...

Two new species of the genus Devadatta Kirby, 1890, D. kompieri sp. nov. from northern Vietnam (holotype: male, Mu Cang Chai district, Yen Bai Province) and D. yokoii sp. nov. from central Laos (holotype: male, Vang Vieng, Vientiane Province) are described. These new species are allied to D. ducatrix Lieftinck, 1969, but are distinguished by specific characteristics of their wings and anal appe...

The study of a new specimen of Petrolestes hendersoni from the Eocene Green Formation allows a more precise description of the enigmatic damselfly and the diagnosis of the Petrolestini. Petrolestes messelensis sp. nov. is described from the Eocene Messel Formation in Germany, extending the distribution of the Petrolestini to the European Eocene. The new damsel-dragonfly family Pseudostenolestid...

The neotropical genus Acanthagrion Selys (Odonata: Coenagrionidae) is composed of 44 species, of which the females of 31 species are currently known. In this contribution the females of A. aepiolum Tennessen and A. minutum Leonard are described and that of A. ascendens Calvert is redescribed. Distribution maps and new records are provided for all three species. Finally, a key to females of the ...
