Mesomphalia ampliata Boheman, 1850

Mesomphalia ampliata Boheman, 1850: 229 ; 1856: 39; 1862: 105; Gemminger & Harold, 1876: 3629; Wagener, 1881: 67; Spaeth, 1901: 339; 1914: 32; Blackwelder, 1946: 737; Borowiec, 1999: 117.

This species has not been revised since description and the holotype has been lost.

Translation of the original description. Subrounded, convex, black, matt; prothorax slightly marked, with arches and whitish pubescence on both sides; elytra with coarse punctuation medially, slightly rugose, with whitish rare pubescence on both sides, wih conic gibbosity and not very angular median region; margin expanded, sparsely punctate. Length. 19.5mm, width 18.25mm. ( Boheman 1850: 229).

Remarks. The loan of the holotype of M. ampliata was solicited through SMNH; however Dr. Johannes Bergsten informed us that the holotype had been borrowed by Dr. Viana, an Argentinian researcher from the Museo Argentino Ciencias Naturales Bernardino Rivadavia, in 1965 and was not returned. We could not locate the holotype in Argentina.

From the original description there is similarity with M. albofasciculata in neither species having macroreticulation or circular impressions on the elytra. However, M. ampliata differs by having pubescence on the pronotum forming arcs; a black scutellum, and elytra with moderately dense punctures.

Geographical distribution. Described from Brazil: Bahia ( Boheman 1850) .
