Genus Trichotichnus Morawitz, 1863

Trichotichnus Morawitz, 1863: 63 [nomen protectum, see Bousquet (2008b: 328)]. Type species: Trichotichnus longitarsis Morawitz, 1863 by monotypy. Etymology. From the Greek trichotos (hairy) and ichnos (footprint, track), probably alluding to the long setae present on both side of the tarsomeres (" Die Fuesse sind unten zu beiden Seiten mit langen Seidenhaaren besetzt ") of the adult [masculine].

Diversity.

About 250 species (Lorenz 2005: 380-382), more than 85% of them inhabiting Asia, arrayed in six subgenera: Amaroschesis Tschitschérine (about 55 species), Bellogenus Clarke (about 45 species), Harpaloxenus Schauberger (12 species), Iridessus (six species), Lampetes Andrewes (nine species), and Trichotichnus s.str. (about 120 species). The Western Hemisphere has only four species, all endemic to eastern North America.

Identification.

Lindroth (1968) reviewed all four North American species, one of them ( Trichotichnus fulgens ) under the genus Harpalus .
