Discovery of Aspidytidae, a new family of aquatic Coleoptera.

Molecular phylogeny of the highly disjunct cliff water beetles (Coleoptera, Aspidytidae) and description of Chinaspidytes gen.nov. for the Chinese lineage

A family event

When it comes to the number of species, beetles are the winners: it is estimated that there are one to 30 million species, comprising one third of all described species. Many remain undescribed and therefore unknown to science. But with such abundance, the mere description of a new species is not necessarily a big event, but researchers, at the Natural History Museum in London and other institu...

The First Report of Leptus N. Sp. (Acari: Erythraeidae) as Ectoparasite of Cassida Persica Spaeth (Coleoptera: Chrysomelidae) from Oil and Gas Company of Gachsaran

Mites of family Erythraeidae are parasites in their larval stage and predators in their post-larval stages on a variety of arthropods, among which are important pest species. During 2011-2013, in a faunistic survey of mites associated with beetles of the family Chrysomelidae in Oil and Gas company of Gachsaranregion, Iran. Specimens were preserved in AG (alcohol 75%, glyserin 5%), cleared in la...

Description of the second and third instars of Aspidytes wrasei Balke, Ribera & Beutel, 2003, with comments on the identification of larvae of Aspidytes Ribera, Beutel, Balke & Vogler, 2002 (Coleoptera: Aspidytidae), and phylogenetic considerations.

The second- and third instar larvae of the cliff water beetle Aspidytes wrasei Balke, Ribera & Beutel, 2003 are studied for the first time with special emphasis on morphometry and chaetotaxy. A review of the characters useful in the identification of larvae of Aspidytes Ribera, Beutel, Balke & Vogler, 2002 is presented. Confirming previous findings, larvae of this genus are unique within Hydrad...
