( Fig. 16 )

Distribution. Brazil (Amazonas, Ceará, Distrito Federal, Espírito Santo, Mato Grosso, Minas Gerais, Pará, Rio de Janeiro, São Paulo) and Paraguay. (Borowiec & Świętojańska 2024).

Material examined. BRAZIL: Ceará, Serra do Baturité, Guaramiranga , RPPN Sítio Lagoa , 15–22.III.2020, M. L. Monné, leg., 4 spec. ( MNRJ: MNRJ-ENT7 45720, 45718, 45721, 45722) .

Collecting method. Malaise trap.

Species diagnosis. It belongs to the S. chalybaea group characterized by strongly convex elytra with postscutellar tubercle and each elytron with three spots of dense pubescence and can be easily separated from all other species of the group by the presence of unique large black and shallow dimples on elytra. Also, S. chalybaea (Germar, 1823) and S. conspersa are the only species of the group having a very smooth, velvet-like texture of elytra. Lastly, some specimens of S. impluviata (Boheman, 1850) , which is often occur sympatrically, have similar size, coloration, and have dimples on elytra as S. conspersa but differ in elytra without postscutellar tubercle.The studied material belongs to the form baturiteana Spaeth, 1940 characterized by smaller size, black-green dorsum (turquoise to blue in the typical form), smaller spots of pubescence, and smaller dimples on elytra presently considered a synonym of S. conspersa .
