It looks rather like Ch. arida Foudras, 1860 than Ch. subcoerulea (Kutschera, 1864). Compare: https://www.cassidae.uni.wroc.pl/Colpol ... 0arida.htm https://www.cassidae.uni.wroc.pl/Colpol ... erulea.htm |

Ch. hortensis is also possible but females of hortensis are usually larger than 2.2 mm with background between punctures matt (https://www.cassidae.uni.wroc.pl/Colpol ... tensis.htm). But I do not rule out this species because the females of hortensis and aridula are, incomparably, difficult to identify even under a stereomicroscope. |

Many thanks to all. After looking the key here https://coleonet.de/coleo/texte/chaetocnema.htm subcoerulea seems to be unlikely hypothesis; actually thorax and elitra are clearly matt, with evident microsculpture. If basal color of antenna (uniformly reddish) is a good character, hortensis too can be probable. ![]()
