Genus Tricholochmaea Laboissière, 1932

Tricholochmaea Laboissière, 1932: 963 (type species Galerucella semifulva Jacoby, 1885 , by original designation).

Remarks

Riley et al. (2003) listed 13 Nearctic species for this Holarctic genus, occurring in both Canada and the United States. Some of the species are subdivided into subspecies, which might more properly be regarded as valid species. Beyond this, several undescribed Nearctic species also belong in this genus ( Ward 1982). Lee & Bezděk (2021) treated Tricholochmaea as a synonym of Pyrrhalta . However, we defer acceptance of this taxonomic change until further evidence is available. See Fig. 22 for a habitus illustration of Tricholochmaea . See Wilcox (1965) and Ward (1982) for keys to the Nearctic species.
