World distribution. Chile . Chilean distribution. From Antofagasta to O’Higgins region ( Fig. 145 ). Altitudinal range. From coastal to highland ecosystems (50– 2,000 m .a.s.l.). Biology and notes. Thompson (1988) revalidated C. longirostre and considered C. concinna as a junior synonym of C. longirostre . This is one of the most common species of the genus, primarily associated with coastal flowering from the Coastal Desert province ( Morrone 2014 ) and Mediterranean basin of Central Chile . This species has been observed visiting flowers of Cistanthe sp. (César Martínez. CSP record); Echinopsis chiloensis (Colla) Friedrich & G.D. Rowley (Dickson Jorquera, CSP record); Eulychnia iquiquensis (K. Schum.) Britton & Rose (Juan Contreras, CSP record); Euphorbia lactiflua Phil. (Benjamín Castro, CSP record); Fuchsia lycioides Andrews (César Martínez, CSP record); H. foliosus (César Martínez, CSP record); Nolana sp. (Rodrigo Castillo, CSP record); Oxalis sp. (Pedro Vargas and Chris Olea, CSP records); Oxalis gigantea Barnéoud (Francisco Santander, CSP record) and Proustia cuneifolia D. Don (Claudio Arancibia, CSP record). Conservation status. LC; EOO = 136,631 km 2 , AOO = 104 km 2 and 24 localities (or subpopulations).
