Volker Assing: Eastern Mediterranean Medon Species 55 age at least as wide as punctures. Elytra with finer, less clear-cut, and distinctly denser puncturation. Hind wings fully developed. Abdomen with fine puncturation and distinct transverse microsculpture. S'- stemite VII shallowly concave and with two combs of usually 4-7 palisade setae (Fig. 51); shape and chae- totaxy of sternite VIII not distinctive (Fig. 52); aedeagus as in Figs. 49 - 50. Intraspecific variation and comparative notes: The following characters were found to be subject to particu- lar intraspecific variation: coloration, eye size, relative elytral length, and density of puncturation. In addition, the shape of the apex of the aedeagus (ventral view), es- pecially the size of the subcircular excavation (i. e. the width of the lateral apical processes) is variable; the apical excavation is often somewhat larger than illus- trated in Fig. 50. From all other Eastern Mediterranean congeners of similar size and dark coloration, except M. pocofer (see diagnosis below that species), M python- issa is readily distinguished by external characters alone, especially by the clear-cut and relatively fine puncturation and the shiny appearance of head and pronotum. The species is highly similar to M diliitus (Erichson), which is distributed in the Western Medi- terranean, as well as in Central and Western Europe. M pythonissa has a slightly more coarsely and more sparsely punctured pronotum, is usually of darker col- oration, has mostly larger eyes, longer elytra, and a less dense elytral puncturation, but is positively separated from M diliitiis only by the morphology of the aedeagus, particularly by the apically distinctly truncate ventral process (ventral view). Comments: The original description of Lithocharis py- thonissa Saulcy is based on a single female from Jerusa- lem. Rem
