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!) ”
