“…However, only Belostoma bifoveolatum (Spinola) might be clearly distinguished from the other two species, B. angustum Lauck and B. elegans (Stefanello et al . ). Appasus major and A. japonicus are different in body size with overlapping distribution, but they can also be identified by their genital morphology (Suzuki et al .…”

“…Male genitalia was supposed to be important for the correct identification of the species of Belostoma bifoveolatum group. However, only Belostoma bifoveolatum (Spinola) might be clearly distinguished from the other two species, B. angustum Lauck and B. elegans (Stefanello et al 2018). Appasus major and A. japonicus are different in body size with overlapping distribution, but they can also be identified by their genital morphology (Suzuki et al 2013) and different genetic structures (Suzuki et al 2014).…”

Giant water bugs (Heteroptera: Belostomatidae) are aquatic predators of freshwater habitats, and include ca. 150 species distributed throughout the world's subtropical and tropical areas. They have unique mating systems, which involve female competition, and exhibit paternal care, wherein males attend eggs laid by the females on emergent plants (Lethocerinae) or on their backs (Belostomatinae). I review here the studies on the predator–prey relationships, morphology, migration, mating behavior and conservation of this family of insects.

“…Therefore, the idea of these variations found in B. micantulum being instead an outcome from differentiated interactions between specimens and environment through their lives (Armbruster et al 2004 with examples in plants; Klingenberg 2015) is not unplausible. Stefanello et al (2018) highlighted that taxonomy strongly or exclusively based on a study of male genitalic morphology in Belostoma may not always be recom-mended because some intraspecific variation in male genitalia has been found inside some Belostoma species with the use of geometric morphometric tools. The monophyly of 'B.…”

The Belostoma plebejum group comprises nine species, and the most evident characteristic shared by all species of the group is a phallus that is strongly curved ventrally. The difficulty in studying its species is much aggravated by the scarcity of identified material in Brazilian collections, and this has negatively impacted phylogenetic studies within the group. We tested the monophyly of the B. plebejum group using discrete and continuous characters under different weighting schemes and inferences. We described B. lanemeloisp. nov. and B. nieserisp. nov. and they served as the basis to study the phylogenetic relationships. A strict-consensus tree recovered under maximum parsimony and with implicit weighting scheme is as follows: (B. parvum, ((B. lanemeloisp. nov., (B. nessimiani, B. nieserisp. nov.)), (B. micantulum var1, (B. micantulum var2, (B. estevezae, ((B. plebejum, (B. minusculum var1, B. minusculum var2)), ((B. nicaeum var1, B. nicaeum var2), ((B. lariversi var1, B. lariversi var2), (B. pygmeum var1, B. pygmeum var2))))))))). The monophyly of the B. plebejum group is corroborated by four non-homoplastic synapomorphies, and the aforementioned condition of the phallus is one of them. We tested the phylogenetic integrity of some species of the B. plebejum group, and only the exemplars of B. micantulum did not constitute monophyletic clades. Comparing the topologies obtained by different approaches clearly showed the presence of different scenarios in terms of heterogeneity of evolutionary rates among characters, but this could also be influenced by the disproportionate number of discrete characters compared with continuous characters.

“…A través de sus aspectos genéticos y del desarrollo, la IM está estrechamente relacionada con las mismas limitaciones evolutivas y del desarrollo (Futuyma, 2010;Klingenberg, 2013b). En la última década, esta temática ha ganado particular protagonismo, en especial por el interés de los investigadores en responder preguntas complejas, que relacionan la variación morfológica con aspectos funcionales, del desarrollo u evolutivos, entre otros (Andjelkovic et al, 2017;Bardua et al, 2019;Bonneau et al, 2014;Curth et al, 2017;Klingenberg, 2013a;Labonne et al, 2014;Maiorino et al, 2017;Neustupa, 2017;Randau & Goswami, 2017;Stefanello et al, 2018;Watanabe et al, 2019;Zollikofer et al, 2017).…”

“…Los estudios de integración morfológica y modularidad difieren de los análisis de redes en otros contextos, porque las interacciones responsables de la integración no son directamente observables y, en cambio, deben inferirse a partir de los patrones de covariación entre rasgos. Debido a esta razón, la modularidad ha sido temática de particular relevancia en la última década, en especial en estudios de evolución del desarrollo, donde varios autores argumentan que proporciona la flexibilidad suficiente para que diferentes rasgos evolucionen más fácilmente bajo demandas funcionales diferentes y/o contrastantes (Andjelkovic et al;Asahara, 2013;Goswami & Polly, 2010;Lehoux & Cloutier, 2015;Maga et al, 2017;Maiorino et al;Randau & Goswami, 2017, 2018Simons et al, 2018;Stefanello et al;Tamagnini et al, 2018;Zollikofer et al). Por consiguiente, la delimitación de módulos a partir de datos sobre patrones de covariación es una preocupación clave para la evolución del desarrollo de la forma (Klingenberg, 2010).…”
