Mesomphalia albofasciculata Boheman, 1856

Mesomphalia albofasciculata Boheman, 1856: 39; 1862: 104; Gemminger & Harold, 1876: 3629; Wagener, 1881: 66; Spaeth, 1901: 339; 1914: 32; Blackwelder, 1946: 737; Borowiec, 1999: 117.

This species remains unknown since its description and the type material has not been located.

Translation of the description. “Rounded, convex, reddish-black, matt; prothorax wide, with sparse and fine punctate, on both sides with sparse whitish pubescence; slightly punctate and strongly gibbous posteriorly; elytra with sparse pubescence, posteriorly sparsely punctate and strongly gibbous; only tuft of whitish pubescence sparse, evident next to posterior margin to suture; anterior median region strongly expanded, curved, anteriorly marked. Length 19mm, width. 18.25 mm. (Boheman 1856: 39).

Remarks. The type specimen has not been studied since the description of the species. Wagener (1881) used the characters described by Boheman (1856) to include the species in a key, and so did Spaeth (1901) to justify the placement of M. albofasciculata in Mesomphalia . Otherwise, the species has only been listed in checklists and catalogs (Spaeth 1914; Blackwelder 1946).

From the original description there are similarities between M. albofasciculata and M. ampliata in absence of macroreticulation or circular depressions on the elytra. However, M. albofasciculata differs by not having arcshaped spots of setae on the pronotum, lateral margins which are parallel, and elytra with sparse punctures and seven tufts of whitish setae next to the margin after the suture.

Geographical distribution. Described from “ Brasília (Boheman 1856) .
