Checklist of water bugs (Hemiptera: Heteroptera: Nepomorpha, Gerromorpha) of Slovakia [PDF]
Zootaxa, 2015 The water bugs represent a significant component of the freshwater biota, play an important role in trophic webs, and may have considerable economic importance. Nevertheless, systematic research of this group has been underdeveloped in Slovakia (central Europe) for decades.

, 2013 Infraorder Gerromorpha Popov, 1971 Gerromorpha is sister group to the Panheteroptera, (i.e., Nepomorpha, Leptopodomorpha, Cimicomorpha, and Pentatomomorpha) (Schuh & Slater 1995), and because members of Nepomorpha are found back into the late Triassic, the Gerromorpha must be of at least the same age (Damgaard 2008).

Life History of an Endangered Marine Insect Halovelia septentrionalis Esaki (Hemiptera: Veliidae)
Psyche: A Journal of Entomology, Volume 2015, Issue 1, 2015., 2015 Halovelia septentrionalis Esaki is one of the endangered marine water striders found along the Japanese coast. It is of primary importance to investigate its life history in the field so as to develop conservation measures as well as to understand how this species has adapted to marine environments. We studied its life history in Misaki on the southern

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 The present study is a cladistic analysis of morphological characters focusing on the file of the mandible, the apices of the maxillae, the rupturing device on the maxillae, the internal structures of the mouthparts, and the external morphology of the labial segments as well as the distribution of labial sensilla in true water bugs (Hemiptera ...

The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013 The present study provides new data concerning the morphology and distribution of the labial sensilla of 55 species of 12 nepomorphan families (Heteroptera: Nepomorpha) using the scanning electron microscope. On the labial tip, three morphologically distinct types of chemosensilla have been identified: two types of papillae sensilla and one type of peg‐

The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013 The present study provides new data concerning the external morphology of the labial segments of 46 species from nine Nepomorpha families using the scanning electron microscope. The labial segments are described in detail and images of their structures are presented for the systematic groups.

New records of Gerromorpha (Insecta: Hemiptera: Heteroptera) from Costa Rica [PDF]
Check List, 2014 The Gerromorpha from Costa Rica are poorly studied, except the Gerridae. Aiming to fill this gap, specimens collected across the country were examined. Lipogomphus leucostictus, Hydrometra alloiona, H. australis, H. huallagana, Microvelia albonotata, M. argentata, M. laesslei, M. mimula, M. panamensis, M. psilonota, M. pulchella, M.

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.Using genome‐skimming, we provide a robust and comprehensive phylogeny of the Gerridae. Our data support the monophyly of all subfamilies except paraphyletic Gerrinae. Non‐monophyly was found for Gerrini, Metrobatini and Trepobatini. Additionally, we reaffirm the non‐monophyly of the genera Aquarius and Tenagogonus, both part of the Gerrinae.

Where Do You Fly From? Assessing Aerial Dispersal in Temporary Rivers Using Stable Isotopes
Freshwater Biology, Volume 70, Issue 10, October 2025.ABSTRACT Dispersal is a crucial ecological process that facilitates gene flow and species exchange within ecosystems. In temporary rivers (TRs), dispersal is a key driver of community assembly because it determines the ability of the organisms to adapt to seasonal drying and maintain stable populations.

Ecology and Evolution, Volume 15, Issue 6, June 2025.We examined the degree of sexual size dimorphism (SSD), based on body length, in approximately 45% of known water bug (Nepomorpha) species. Contrary to our initial hypothesis, we found that females are not significantly longer than males in most species. Our research revealed that habitat plays a significant role in SSD.
