Tomáš Lackner Revision of the genus Hemisaprinus Kryzhanovskij…

Carinal prosternal striae of Hister subvirescens do not enter the prosternal foveae; while the lateral prosternal striae do. In the case of the two other species (Hemisaprinus lutshniki and Hemisaprinus cyprius) the carinal prosternal striae do terminate in the prosternal foveae, while the lateral prosternal striae terminate near the apices of carinal prosternal striae. According to my recent studies on the morphology of the Saprininae, the configuration of the two sets of prosternal striae was found to be a rather variable character, even within one genus (and even within one species!)

Tomáš Lackner Revision of the genus Hemisaprinus Kryzhanovskij…

All three species Hemisaprinus subvirescens (Ménétries, 1832) , H. lutshniki (Reichardt, 1941) and H. cyprius (Dahlgren, 1981) are found to be correctly assigned to the genus and their monophyly is supported by the synapomorphy of the presence of prosternal foveae. The three species are re-described and supplemented with colour photographs as well as SEM micrographs outlining their differences. Male genitalia drawing of H. subvirescens and H. lutshniki are provided and a key to the species is given.

Humeral elytral stria weakly impressed on basal third; inner subhumeral stria present as short median fragment; all four dorsal elytral striae 1–4 weakly impressed, short, not reaching elytral half apically, in shallow punctures; fourth dorsal elytral stria basally vaguely connected with sutural elytral stria; sutural elytral stria well-impressed and complete, in deep punctures, apically connected with apical elytral stria; entire elytral disc with punctuation, punctures dense and coarse
