03D987A5FF87D81803FAF8FAFD59FBFB.taxon	diagnosis	Diagnosis. Mimoplatycis alekseevi sp. nov., resembling in the narrow body M. bicolor Fanti et Vitali, 2017, may be distinguished from it by the acute and noticeably produced laterally posterior pronotum angles and relatively wide median areole between the front pronotal carinae (Figs 2 A, 4 B), vs the rounded and not produced laterally posterior pronotum angles and narrow median areole between the front pronotal carinae in M. bicolor. Although the authors of the latter taxon also describe its bicolorous elytra (Fanti & Vitali, 2017), the photos they provide suggest the elytra are more likely uniformly dark brown (or reddish brown, in passing light), with the basal triangle looking darker, as the thorax does not allow light to pass through, and their apices also darker due to the apical bulges.	en	Kazantsev, S.
