Calopachys viridissimum georgeballi Lassalle & van den Berghe, 2010: 112 (type: env. Oaxaca; coll. Lassalle)

Length 21-25 mm. It was described in a single female specimen presumably coming from Mexico (Jeannel 1940: 233). A further female specimen was subsequently captured in the southern Sierra Madre do Sur (10 km .... NW Oaxaca) , in oak forests (Erwin, 2007: 84).
Recently, some specimens of both sexes were found in the mountainous areas near Oaxaca. These specimens, that markedly differ in color from those previously known, have been described as Calopachys viridissimum georgeballi (Lassalle & van den Berghe, 2010: 112).

Examined specimens and literature’s data
Mexico. Mexique interieur (type, MNHN); Oaxaca, 10 km NW Oaxaca (Erwin, 2007: 84); env. Oaxaca (paratype of Calopachys viridissimum georgeballi) (SB)

Notes: Brachypterous. It lives in oak forests and seems to be active in daytime too. Adults were collected in August and September.
