Map 11: Distribution of Medon fusculus (Mannerheim) (filled circles: revised records; open circles: selected literature records). Diagnosis: In external appearance similar to M. fuscu- lus. mm. Coloration reddish brown to dark brown, with the head usually slightly darker; legs and antennae yellowish brown to ferrugineous. Head about as wide as long or weakly transverse and times as wide as pronotum (Fig. 95); eyes relatively large, in dorsal view more than half the length of temples; puncturation dense, coarse, well-defined, and areolate; interstices with noticeable shine. Pronotum approximately as wide as long or weakly transverse (Fig. 95); puncturation on the whole similar to that of head, but usually shallower, slightly less dense, and less well-defined; usually with, more rarely without impunctate median line. Elytra relatively large, times as wide and at suture about times as long as pronotum (Fig. 95); puncturation much finer and less dense than that of head and pronotum; interstices shining. Hind wings appar- ently fully developed. Protarsomeres I - IV without sex- ual dimorphism, transverse in both sexes; tarsi relatively short, metatarsomeres III and IV less than twice as long as broad. Abdomen finely and densely punctate; posterior margin of tergite VII with palisade fringe. (j1: posterior margin of sternite VII of similar morphol- ogy and chaetotaxy as in other species of the M. fuscu- lus group, deeply and broadly concave (not distinctly trapezoid), with two lateral combs of palisade setae and on either side of middle with a distinct tuft composed of very long dark setae (Fig. 96); sternite VIII similar to that of M. fusculus and related species (Fig. 97); aedeagus of distinctive shape (Figs. 98-99).
