“…It differs from all these species by the ventral projection on the right posterolateral margin of abdominal segment VIII, which is subequal in length and width (Fig 18D and 18E). This new species is similar to P. vivatus, and specimens from Colombia have been confused with it in the literature [1, 16,35,36,38,50]. The new species can be distinguished from P. vivatus mainly by the position of the posterolateral projection of male abdominal segment VIII, which is ventral in the former (Fig 18D and 18E), but dorsal in the latter (Fig 27B).…”

Potamobates Champion, 1898 (Hemiptera: Heteroptera: Gerridae) heretofore included 18 species distributed from southern Mexico to Peru. They display a distinct morphology, especially regarding the projections of abdominal segment VIII. Specific identification and delimitation are difficult, and the genus lacks a thorough revision and evaluation of inter- and intraspecific variation. Here, we revise Potamobates, redescribe and/or illustrate known species, and describe P. molanoi Floriano and Moreira, sp. nov. and Brailovskybates Floriano and Moreira, gen. nov. The new genus is erected for P. thomasi Hungerford, 1937 and is characterized by the following features: (1) abdomen elongated, longer than the mesothorax; (2) abdominal spiracles positioned at the center of the segments; (3) male abdominal segment VIII without projections; (4) male pygophore and proctiger not rotated in relation to the longitudinal axis of the body; (5) female abdominal tergum VIII subequal in length and width; (6) and posterior margin of female abdominal sternum VII not produced medially, with a pair of lateral projections.

“…The semi-aquatic hemipteran infraorder Gerromorpha Popov [1] comprise water striders and their allies, which are conspicuously adapted to motion, feeding and mating on the water surface, occupying a vast array of niches including freshwaters, lagoons, sea near the coasts and even the pelagic environments [2,3]. The specialized morphology and diverse behaviour of gerromorphans have become hotspots in evolutionary biology, ecology and even interdisciplinary studies, and provided a theoretical basis for developing biomimetic technology on the surface of water [4][5][6].…”

Fossilized mating insects are irreplaceable material for comprehending the evolution of the mating behaviours and life-history traits in the deep-time record of insects as well as the potential sexual conflict. However, cases of mating pairs are particularly rare in fossil insects, especially aquatic or semi-aquatic species. Here, we report the first fossil record of a group of water striders in copulation (including three pairs and a single adult male) based on fossils from the mid-Cretaceous of northern Myanmar. The new taxon, Burmogerris gen. nov., likely represents one of the oldest cases of insects related to the marine environment, such as billabongs formed by the tides. It exhibits conspicuous dimorphism associated with sexual conflict: the male is equipped with a specialized protibial comb as a grasping apparatus, likely representing an adaptation to overcome female resistance during struggles. The paired Burmogerris show smaller males riding on the backs of the females, seemingly recording a scene of copulatory struggles between the sexes. Our discovery reveals a mating system dominated by males and sheds light on the potential sexual conflicts of Burmogerris in the Cretaceous. It indicates the mating behaviour remained stable over long-term geological time in these water-walking insects.

“…Esta región se caracteriza por presentar una alta riqueza y presencia de endemismos entre los que se destacan las plantas y animales vertebrados (aves, mamíferos, reptiles y anfibios) (Myers et al, 2000). En el caso de los insectos, las chinches semiacuáticas han presentado una alta riqueza en la región pacífica con 29 especies registradas (Galindo-Malagón et al, 2021Mondragón-F et al, 2021;Padilla-Gil, 2010, 2011, 2015a, 2015b, 2016, por lo que ha sido categorizada como la que mayor número de especies de chinches de ecosistemas marinos presenta en toda la región Neotropical (Padilla-Gil, 2015a;Molano-Rendón & Morales, 2017).…”

“…A pesar de la alta biodiversidad de chinches semiacuáticas en la región neotropical y en regiones como el Chocó biogeográfico de Colombia, aún existen vacíos de información en los ecosistemas marinos (Cordeiro & Moreira, 2015;Mosquera-Murillo & Mosquera-Mosquera, 2017), debido en gran parte a que los estudios se han centrado en hábitats de agua dulce (Molano-Rendón & Morales, 2017). Estos vacíos de información pueden ocasionar una baja estimación de la biodiversidad en cuanto al verdadero número de especies y los patrones reales de distribución de estas (Floriano et al, 2017).…”

Esta investigación registra las especies de chinches semiacuáticas (Hemiptera: Gerromorpha) de la franja costera del Parque Nacional Natural Utría (Chocó, Colombia). Durante una salida de campo en el mes de febrero de 2019, se recolectaron individuos en diferentes tipos de hábitats: ensenada, manglar, playa y quebrada. En cada hábitat se hicieron recolectas por medio de redes entomológicas acuáticas, con un esfuerzo de muestreo de dos horas/hombre. Se lograron recolectar 192 individuos, donde el 93% fue determinado a especie y el 7% a género. Así, se lograron registrar 11 especies y dos morfoespecies, cuatro especies para la familia Gerridae y siete para la familia Veliidae. Las morfoespecies pertenecen a los géneros Rhagovelia y Microvelia (Veliidae). Se resalta el registro de cuatro especies endémicas para el Chocó biogeográfico que han sido descritas recientemente: Rhagovelia molanoi, Rhagovelia nuqui, Rhagovelia utria y Stridulivelia chocoana. Los resultados de este proyecto estuvieron dentro del Marco de la revisión taxonómica de la familia Hydrometridae para Colombia
