Genus Archicolliuris Liebke, 1931

Type species: Casnonia bimaculata Kollar & Redtenbacher, 1844 , by original designation.

Liebke (1931, 1933, 1938) proposed a subdivision of the highly diverse ancient genus Colliuris Degeer, 1774 in many different subgenera. Currently, the American subgenera are all often regarded as subgenera of Colliuris , whereas, the African and Asian subgenera have been split among various genera, the largest of which are: Odacantha Paykull, 1798 , Eucolliuris Liebke, 1931 , Ophionea Klug, 1821 and Archicolliuris Liebke, 1931 . In particular, Archicolliuris , contains species previously considered belonging to the Asian subgenera Anacolliuris Liebke, 1938 , Eucasnonia Liebke, 1938 and Anacasnonia Liebke, 1938 , as well as the Afrotropical subgenera Stenidiomorpha Liebke, 1938 , Panapiodera Liebke, 1933 and Archicasnonia Liebke, 1938 . The genus Archicolliuris , in the present sense, is considered as widely distributed in the Afrotropical, Asian and Australian regions and is very heterogeneous. Some species have a very superficial elytral punctuation and coloration pattern similar to that of Ophionea , while others have strongly impressed striae and a completely different elytral pattern. Basilewsky (1956) groups all the subgenera from Africa under Archicolliuris without explanations. Only few years later, Jedlička (1963) still considers all the Asian subgenera as belonging to Colliuris .

Noting the great heterogeneity of this genus, we believe that it would be advisable to revise all of the species here ascribed, and verify which of these subgenera could be reevaluated, in order to reflect a more precise understanding of the systematics of the group.

Among these subgenera, Anacolliuris has A. tenuis as the type-species, and according to Liebke (1938) contains the taxa A. tenuis tenuis Andrewes, 1926 , A. tenuis linea Andrewes, 1926 and A. tetraspilota Schmidt-Goebel, 1846 . Later Kirschenhofer (1994) considers Anacolliuris as a valid subgenus of Colliuris and in a subsequent work, Kirschenhofer (1996) raises it to the genus rank, adding two new species, A. kodadai and A. butonensis . While the first of these two is certainly extremely close to A. tenuis (and possibly a synonym of A. tetraspilota ), we do not know directly the second one, but from the original illustration it seems to fit better within the genus Mimocolliuris , probably being a senior synonym of M. unimaculata Baehr, 2016 , both being known for Sulawesi.
