Anisodactylus (Anadaptus) alternans (Motschulsky, 1845)

PWM taxonomic note inserted into the species info page:
Bousquet & Larochelle (1993: 14) and Bousquet (2012: 1033) established that
Anisodactylus (Anadaptus) alternans
(Motschulsky, 1845) is the synonym senior to
Anisodactylus alternans
LeConte, 1851;
Anisodactylus nivalis
G.H. Horn, 1880;
Anisodactylus parvulus
(Casey, 1914). The revision of subgenus
Anadaptus
by Noonan (2001) unfortunately missed Motschulsky's seniority. Otherwise, Noonan's 2001 key corrects the misplacement of
A. alternans
in Lindroth's 1968 key. Two colored morphs are sympatric: the bicolored morph and the less common dark morph.
