First record of the tribe Scymnini Mulsant (Coleoptera: Coccinellidae: Coccinellinae) for Alagoas, Brazil

Scymnini Mulsant, 1846 (Coleoptera: Coccinellidae) is a cosmopolitan group of inconspicuous beetles, and Scymnus Kugelann is the richest genus of this tribe, with more than 700 species in 10 subgenera occurring worldwide, being Pullus Mulsant its most species-rich group, with 30 species in South America and 10 species in Brazil. Although all Scymnini genera have been revised for South America, this tribe has not yet been recorded for Alagoas. Thus, we make here the first record of this tribe for this State of Brazil. In January 2025, two specimens of Coccinellidae were collected in Arapiraca, mesoregion of Alagoas, area characterized by a hot semi-arid climate. The adults were studied and dissected to study the genitalia as well. The examined material was deposited in the Coleção Entomológica Padre Jesus Santiago Moure (DZUP). The beetle is Scymnus (Pullus) rubicundus Erichson, 1847. This species is distributed in almost all of South America, being the most collected Scymnus in this continent, but interestingly, not even the tribe has been reported for Alagoas. Records such as these are valuable for our better understanding of the tiny, inconspicuous Coccinellidae, a family of beetles that are also economically important. Knowing this, we also provide an identification key for Scymnini genera from northeastern Brazil.
