Specialization to extreme environments is often considered an evolutionary dead-end, leading to irreversible adaptations and reduced evolvability. There is, however, mixed evidence for this macroevolutionary pattern, and limited data from speciose lineages. Here, we tested the effect of habitat specialization...
The presence of Aphelocheirus aestivalis (Fabricius, 1794) (Hemiptera: Aphelocheiridae) in the Iberian Peninsula has been on the spot in the last decades. New records collected in northern inner plateau (Riaza River, Duero Basin) provide new insights about the presence of this species in the Iberian Peninsula...
Ochthebiinae, with c. 650 species distributed worldwide, are the second most speciose subfamily of the aquatic beetle family Hydraenidae. They are ecologically the most diverse hydraenid subfamily, with terrestrial species as well as species in almost all types of aquatic habitats, including hypersaline waters...
Some species of the diving beetle tribe Hygrotini (subfamily Hydroporinae) are among the few insects able to tolerate saline. concentrations more than twice that of seawater. However, the phylogenetic relationships of the species of Hygrotini...
We describe a new species of Micragasma J. Sahlberg, 1900 (Coleoptera, Hydraenidae), which is here treated as a subgenus of Ochthebius Leach, 1815. The new species, O. (Micragasma) minoicus sp. n., was found at the margins of a coastal rockpool in …
The tribe Hygrotini Portevin, 1929 is currently composed of four genera, Heroceras Guignot, 1950, Herophydrus Sharp, 1880, Hygrotus Stephens, 1828 (with two subgenera, Coelambus Thomson, 1860, and Hygrotus s. str.), and Hyphoporus Sharp, 1880. A …
