“…Specimens of Belostoma were collected with fine mesh water nets and light‐traps, and preserved in 70% ethanol. Species were identified with taxonomical keys and genital dissections of specimens (Schnack 1976; Estévez & Polhemus 2007; Ribeiro & Alecrim 2008). Lethocerus annulipes were collected from Venezuela, and are housed in the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” (MACN).…”

Current evidence suggests that sexual size dimorphism (SSD) reflects the male and female adaptation to their different reproductive roles. Belostoma and Lethocerus species, included in Belostomatidae, present different kinds of paternal care. Females of Belostoma Latreille species lay their eggs on the back of males. Males carry, aerate and protect the clutch until hatching, which is critical for offspring survival. Males of Lethocerus Mayr species exhibit some parental care behavior but do not carry the eggs. The genera are nearly related. We studied and compared the SSD patterns of B. oxyurum (Dufour), B. micantulum (Stål), B. elegans (Mayr), B. bifoveolatum Spinola, B. gestroi Montandon and Lethocerus annulipes (Herrich‐Schäffer) by means of a multivariate approach to distinguish selection targets in different components of size. Morphometric analysis revealed that SSD patterns vary among traits and that the arrangements are similar in Belostoma species, showing a common trend under resembling selective mechanisms. The widespread SSD trend in insects is that all components of body size are biased towards females, generally related to a fecundity advantage, a pattern now also detected in L. annulipes. We found in Belostoma species that the male has relatively longer middle and hind legs. We propose that SSD in hind legs biased towards males is a selective response for paternal care; they denote a brood‐adapted morphology. The middle leg enlargement may be an associated response to maintain effective locomotion.

Disentangling the taxonomy of Belostoma Latreille (Hemiptera: Belostomatidae) with the aid of DNA barcoding approaches

et al. 2021

Belostoma is the most diverse genus of Belostomatidae, comprising 74 species. The small Belostoma species are challenging to identify mainly due to the presence of cryptic species. As DNA barcoding has been a crucial tool to solve the taxonomic impediment associated with many taxa, we compared species delimitations obtained by morphological and molecular approaches, in order to help to disentangle the taxonomy of Belostoma. We sampled 192 specimens of Belostoma across the Rio Grande do Sul Brazilian Coastal Plain. Specimens were first identified with the use of morphological markers and then characterized for two mitochondrial markers: cytochrome C oxidase subunit I (COI) and 16S rRNA genes, generating 181 and 164 sequences, respectively. These were complemented with Belostoma sequences downloaded from NCBI/BOLD (101 for COI & 13 for 16S). Thus, matrixes including 282, 177 and 299 sequences for COI, 16S and the concatenated data set, respectively, were analysed through phylogenetic, phylogeographic and distance approaches. The initial morphological evaluation allowed the identification of 14 male genitalia morphotypes, whose sequences were added to a preliminary matrix containing NCBI/BOLD sequences of five other described species, allowing us to recover 10 clades in the molecular analyses. Patterns of reciprocal monophyly were confirmed for only six of the studied species: Belostoma angustum, Belostoma cummingsi, Belostoma dentatum, Belostoma noualhieri, Belostoma orbiculatum and Belostoma ribeiroi. Belostoma candidulum, Belostoma horvathi and Belostoma sanctulum appeared intermingled in a single clade. The grouping of these with the other five distinct (male genital) morphotypes reveals a clade with high levels of morphological polymorphism or phenotypic plasticity.

“…The life cycle of species in this family are fully dependent on freshwater habitats, mainly permanent or temporary ponds, streams and the edges of rivers. In Brazil, 52 species are currently recorded, distributed among four genera: Belostoma Latreille, 1807, Horvathinia Montandon, 1911, Lethocerus Mayr, 1853and Weberiella De Carlo, 1966 (Estévez & Polhemus, 2001;Ribeiro, 2007;Ribeiro & Alecrim, 2008;Ribeiro & Estévez, 2009;Moreira et al, 2011;Ribeiro et al, 2018).…”

In addition to these type specimens, INPA's collection houses many non-type specimens that are unidentified, mainly representing the North region, with some species being exclusive to the Amazon region.…”

Belostomatidae is a family of giant water bugs with 52 valid species in Brazil. Here, we list 33 valid species housed in the Invertebrates Collection of the Instituto Nacional de Pesquisas da Amazônia – INPA, Manaus, Brazil. Of the total species examined, 26 had their distributional ranges increased (new records provided in parentheses): Belostoma amazonum Estévez & Polhemus (Mato Grosso and Roraima); B. aurivillianum (Montandon) (Rondônia); B. bosqi De Carlo (Maranhão); B. candidulum Montandon (Mato Grosso do Sul); B. carajaensis Ribeiro & Estévez (Amazonas); B. dallasi De Carlo (Bahia and Pará); B. dentatum (Mayr) (Roraima); B. denticolle Montandon (Roraima); B. dilatatum (Dufour) (Maranhão); B. discretum Montandon (Rio Grande do Sul); B. elongatum Montandon (Paraná); B. estevezae Ribeiro & Alecrim (Amazonas); B. fittkaui De Carlo (Roraima); B. gestroi Montandon (Pará); B. guianae Lauck (Brazil, in Roraima); B. micantulum (Stål) (Maranhão, Rio Grande do Norte, Rondônia and Roraima); B. minusculum (Uhler) (Brazil, in Amazonas, Pará and Rio Grande do Norte); B. parvum Estévez & Polhemus (Amazonas and Roraima); B. plebejum (Stål) (Roraima); B. pygmeum (Dufour) (Pará); B. ribeiroi De Carlo (Mato Grosso do Sul); B. stollii (Amyot & Serville) (Roraima); Horvathinia pelocoroides Montandon (Rondônia); Lethocerus annulipes (Herrich-Schaeffer) (Maranhão, Paraíba and Paraná); L. delpontei De Carlo (Amazonas and Pará) and L. maximus De Carlo (Acre, Amapá, Amazonas and Roraima).
