Cosmoclopius annulosus Stal 1872

Cosmoclopius annulosus Stål, 1872 Cosmoclopius Stål, 1866 currently includes eight species and is largely distributed from Curaçao to Argentina, including Brazil (Cobben and Wygodzinsky 1975; Melo and Coscarón 2004; Varela and Melo 2021). The specimens of C. annulosus measure about 12 mm in length (Stål 1872), and display a mostly pale coloration (yellowish, greenish or reddish) with several dark rings on the legs, which are less marked on the fore femora (Fig. 3G). The species of this genus are polyphagous predators. While there are several records of prey of C. nigroannulatus Stål, 1872 summarized by authors such as Jahnke et al. (2002) and Marques et al. (2006), there is a lack of information about C. annulosus, which has only been recorded preying on Ceratina rupestris Holmberg, 1884 bees (Apinae: Xylocopini: Ceratinina) (Marsaro Júnior et al. 2022). Distribution. Cosmoclopius annulosus was described from specimens from Santa Catarina, Brazil (Stål 1872). It has also been recorded to Argentina (Melo and Coscarón 2004) and recently to the state of Rio Grande do Sul, Brazil (Marsaro Júnior et al. 2022).
