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

Phylogenetic Signals from Nepomorpha (Insecta: Hemiptera: Heteroptera) Mouthparts: Stylets Bundle, Sense Organs, and Labial Segments

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 ...

Comparative Analysis and Systematic Mapping of the Labial Sensilla in the Nepomorpha (Heteroptera: Insecta)

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‐

Relations of habitat integrity and spatial structure on the Gerromorpha community (Hemiptera: Heteroptera) in streams under the influence of protected area in Oriental Amazon

Brazilian Journal of Biology
The community of semiaquatic insects (Gerromorpha) is related to forest cover and habitat integrity, as well as spatial factors such as the distance between streams.

Deliberations on the External Morphology and Modification of the Labial Segments in the Nepomorpha (Heteroptera: Insecta) with Notes on the Phylogenetic Characteristics

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.

On the Origin of the Tingidae (Insecta, Heteroptera)

Zoologica Scripta, EarlyView.
ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...

Exploring the phylogenetic history of water striders (Hemiptera: Heteroptera: Gerromorpha) using genome‐skimming

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.
