Head chaetotaxy was nearly identical between instars. Ventral teeth on the nasale, considered as a useful taxonomic character, were absent in the first instar but well developed in later instars.

Abstract:

The geographic structure of Türkiye is well-suited for determining species diversity and interspecific variation as Türkiye has many regions with different altitudes and ecological characteristics. A large number of specimens belonging to the Helophoridae family belonging to the order Coleoptera were collected from different regions of Turkey between 2007-2021, examined and kept as museum material. Among the museum materials evaluated in terms of variation, Helophorus (Helophorus) aquaticus (L., 1758) species were seen to be both more common and more diverse in each region. In this study, male

Abstract:

Abstract Twenty-three sites within the Slavíč river basin (Silesia, Czech Republic) were surveyed to obtain up-to-date information on water beetles in the area. In total, 46 species comprising eight families were recorded. Significant findings included Ochthebius melanescens Dalla Torre, 1877, Hydrocyphon deflexicollis (Müller, 1821) (both endangered), Hydraena morio Kiesenwetter, 1849, Eubria palustris (Germar, 1818) (both vulnerable), Hydraena minutissima Stephens, 1829 (near threatened) and Elodes pseudominutus Klausnitzer, 1971 (data deficient).

Abstract:

New data on the distribution, ecology, and phenology of Helophorus pitcheri Angus, 1970, previously known from three type specimens from Southern Siberia and a single find from China, are presented. The species is recorded for the first time from the Russian Far East (Amur Region and Khabarovsk Territory). Biotopes are indicated, and a list of Hydrophiloidea species which was found with H. pitcheri is given. Presumably, the species is an acidophilic stagnophile. Adults were found in June and August.

Abstract:

Despite aquatic coleoptera are a well-studied group in the Iberian Peninsula, at a smaller spatial scale, there are still areas with scarcity in their inventories. Using an extensive database, which compiles bibliographic citations and unpublished samplings carried out in the area from the 1980s to the present, the catalogue of aquatic Coleoptera species from central Sierra Morena has been updated and contains 144 species, 22 of which are Iberian endemism. 19 species are cited for the first time in the province of Cordoba.
