Calosoma (Callitropa) viridisulcatum Chaudoir, 1863
Calosoma viridi-sulcatum Chaudoir, 1863: 114 (described from: Mexique intérieur); type material: not stated, description compatible with one specimen only; “holotype” in Museum and Institute of Zoology, Warsaw (Mroczkowski, 1960: 377) and holotype ♀ designated by Deuve (1978: 251) by monotypy (no locality label) in Muséum National d'Histoire Naturelle, Paris [examined]

Blaptosoma viridisulcatum vanderberghei Lassalle, 2009: 10 (type locality: Pto de la Campagna, est de Mascota); holotype ♂ in coll. Lassalle, 24 paratypes in coll. Lassalle and in coll. van den Berghe
Length 24-28 mm. viridisulcatum has on each elytron four black ribs (corresponding to the secondary intervals) and, within each of them, three flattened green bands representing the vestiges of primary intervals.
The color is very variable and this, together with other minor morphological variations, led to description of many individual forms or populations.
Breuning (1928b: 45) and Jeannel (1940: 216) knew C. viridisulcatum only from the surroundings of Guadalajara in the state of Jalisco. Later Beheim & Breuning (1943: 22) described a population from the state of Zacatecas, Gidaspow (1959: 279) indicated a larger distribution including also the states of Querétaro, Nayarit, Colima and Guerrero. Finally Lassalle & van den Berghe (2010: 112), based on more recent researches, specified that C. viridisulcatum is found in the state of Jalisco and that it enters the southern part of the state of Zacatecas. However, it can not be excluded that it spreads beyond the border also into the neighbouring state of Nayarit , Instead, the indication of Atenquique in the state of Colima and Pacana in the state of Guerrero almost certainly come from mere mistakes since the two places belong to the state of Jalisco but do not exist in the two states mentioned. Even the presence of C. viridisulcatum in Querétaro (Arroyo Seco) seems very unlikely, and it should keep in mind the possibility of another similar mistake since a towns with the same names is also found in Jalisco.
Examined specimens and literature’s data
Mexico. Jalisco: Atentiquique, Pacana (Gidaspow, 1959: 279), Guadalajara (Bates, 1891: 223), surroundings of Guadalajara (lectotype of laetulum MNHN), Jacotepec 1500 m (EM, SB), El Pitahayito 1500 m (EM), Ameca (AVT), Pala (GP), Ajijic, junction on the road to Ameca, Salatitlan, Chapala lake, Tlaquepaque (Gidaspow, 1959: 279), East of Mascota (Lassalle, 2009: 10), Cocula, San Sebastián del Oeste, Atenguillo, Ixtlahuacán del Río, Ixtlahuacán de los Membrillos, El Salto, Santa María de los Ángeles, Tapalpa, Tlajomulco de Zúñiga (www.inaturalist.org/); Nayarit: Tepic (Gidaspow, 1959: 279); Zacatecas (Beheim & Breuning, 1943: 22): Moyahua de Estrada (TL).
Notes: C. viridisulcatum is brachypterous and ground-dwelling, found in pastures, grasslands and cultivated fields from 1500 to 2300 m. Diurnal activity has been observed in full sun, with the beetle scurrying along the ground. Adults are mostly active between May and October, but some individuals have been observed in December and January.
