Explanation of Names
Malthodes Kiesenwetter 1852
Numbers
the most speciose cantharid genus, with ~130 spp. in our area, hundreds worldwide(1)
Size
1-4 mm
Identification
Tiny cantharids with shortened elytra
Species of small size and weak structure, having short elytra which leave the inner wings partly exposed and folded along the dorsal surface of the abdomen; head not narrowed into a neck and mandibles not toothed.(2)
Species identification requires examining the exposed copulatory male terminalia; identification of females is virtually impossible
Terminalia "varying from a comparatively simple arrangement with the last dorsal segments simple and the seventh ventral elongate, with or without an apical notch; to a complex and intricate pattern that in some species approaches the grotesque. No other North American group of beetles, known to the author, offers such a wealth of interesting features as do these tiny creatures."(3)
Range
New World, Eurasia, Africa; widespread in NA but most spp. in the west(1)
Remarks
Uncommonly collected, but some spp. locally abundant(1)
