Remarks. Mesomphalia calvata was until now an enigmatic species to cassidinae workers and was listed only in catalogues and last assigned to the genus Stolas (BOROWIEC 1999a) . However, the holotype of the species has broad ultimate tarsomere and belongs to Agenysa . In my opinion it is conspecific with A. connectens aequatoriensis, which is, however, very different from typical A. connectens as it has high reticulation on elytra.

It is possible that A. calvata is conspecific also with A. lacertosa (Boheman, 1862) (= A. crassicornis Spaeth, 1905), which might represent only a montane form with black elytra while A. calvata always has a red reticulation on explanate margin of elytra. However, this problem requires further study and I provisionally consider both, A. calvata and A. lacertosa, as distinct species.

This species is distributed in the northern part of the Andes and adjacent foothills mostly on eastern slopes or central valleys.

Distribution. Ecuador (SPAETH 1916) and Peru (BOHEMAN 1862).
