Pyrrhalta Joannis, 1865

Pyrrhalta Joannis, 1865: 82 (type species: Galeruca vibruni Paykull, 1799).

Lochmaea (Tricholochmaea) Laboissière, 1932: 963 (type species: Gallerucella semifulva Jacoby, 1885; by original designation). Synonymized by Gressitt and Kimoto 1963: 438.

Tricholochmaea : Chûjô & Kimoto, 1961: 169; Riley et al. 2002: 655; Riley et al. 2003: 71.

Pyrrhalta (Tricholochmaea) : Wilcox, 1965: 37; Wilcox 1971: 80.

Pyrrhalta (Pyrrhalta) : Wilcox, 1971: 84.

Remarks.

Weise (1886), Reitter (1913), and Ogloblin (1936) overlooked the fact that Pyrrhalta Joannis, 1865 has priority over Gallerucella Crotch, 1873. Therefore, the former cannot be a subgenus of the latter ( Gressitt and Kimoto 1963). There are no reliable characters for distinguishing Pyrrhalta Joannis and Tricholochmaea Laboissière. We conclude that establishing species groups as a basis for classification, rather than retaining the generic status of Tricholochmaea is a better approach. Tricholochmaea is regarded as synonym with Pyrrhalta in this study.
