Anhanga is a genus of Brazilian shield bugs, erected by William Lucas Distant in 1887.[1]

Taxonomy

Originally described from the subfamily Discocephalinae (Discocephalini), Anhanga was reassigned by a 2016 study to the Pentatominae subfamily. Anhanga is rare in museums with four specimens in total, and had not been evaluated since its description by Distant in 1887.[2]

Anhanga's general and genital morphology aligns best with Galedanta, another Neotropical pentatomine shield bug. Mutually aligned features include a medium-sized to large body covered in punctures, mandibular plates rounded at apex which are convergent and longer than clypeus, and scutellum bearing foveae. Females bear finger-like processes, with males possessing a projected 'V-shaped' ventral rim of the pygophore. However, Anhanga can be distinguished by the rounded lateral angles of the anterolateral margin of pronotum crenulate along the anterior half of specimens.[2]

Ecology

Anhanga is endemic to the moist ranges of Atlantic forest in Rio Grande do Sul, Brazil ,[2] and the Buenos Aires Province, Argentina .[3]
