A new South American toe biter (Hemiptera, Belostomatidae )

Weberiella De Carlo, 1966 (Insecta: Heteroptera: Belostomatidae) revisited: Redescription with a key to the genera of Belostomatidae and considerations on back-brooding behaviour

“…Up to now nothing was known about oviposition and life history of Weberiella, one that is a lineage of apparently basal Belostomatinae and a monotypic genus restricted to small areas in Guyana and Brazil (Menke, 1965;De Carlo, 1966;Nieser, 1975). The only known living species was described by Menke (1965) as B. rhomboides Menke, 1965 (based on a single female).…”

The only known living species was described by Menke (1965) as B. rhomboides Menke, 1965 (based on a single female). He pointed out the presence of air straps and a narrow hemelytral membrane like in Belostoma species, and one-segmented foretarsi like in Horvathinia pelocoroides Montandon, 1911 andDiplonychus urinator urinator (Dufour, 1863).…”

“…He was the first to use male genitalia in his taxonomic treatment. Later, Nieser (1975) redescribed the type material from French Guiana as well as the supposed male allotype from Amazonas (Menke, 1965). He remarked that Weberiella differs from the other genera of Belostomatidae by the generic characteristics given by De Carlo (1966).…”

“…After studying them, other conspecific male and female specimens were found at the collections of the Instituto Nacional de Pesquisas da Amazônia (Manaus, Brazil), Museo Argentino de Ciencias Naturales "B. Rivadavia" (Buenos Aires, Argentina) and Museo de Ciencias Naturales de La Plata (La Plata, Argentina). A more comprehensive redescription of W. rhomboides is presented herein, and the number of segments of the foretarsi (De Carlo, 1966;Menke, 1965;Nieser, 1975) is corrected. The redescription includes modifications and clarifications of non-genitalic and male genitalic features, which were inaccurately described by De Carlo (1966) and Nieser (1975).…”

Checklist of Aquatic Heteroptera genera (Insecta: Hemiptera) from Brazilian Savanna (Cerrado Biome), with family and genera identification key

“…In the Neotropical region, the subfamily Belostomatinae is represented by three genera: AbedusStal, 1862, Belostoma Latreille, 1807 and Weberiella De Carlor, 1966(Panizzi & Grazia 2015.The genus Belostoma is the most diverse genus, with 77 neotropical species ranging from Mexico to Argentina (lauck 1959; lanzer de souza 1980, 1992; estévez & PolHemus 2001, 2007; estévez & armúa de reyes 2003; ribeiro & alecrim 2008; ribeiro & estévez 2009). Weberiella is exclusively neotropical, with Weberiella rhomboides(Menke, 1965), taking place in the North and midwest of Brazil and French Guiana (estévez & ribeiro 2011). According toHeckman (2011), this genus occurs only in French Guiana and in the Amazon.…”
