Distribution: From Metropolitan to Los Ríos ( Fig. 13 ).

Diagnosis: Black body with abundant and short brownish pilosity on the head and oral parts. Head with a short projection densely pilose on the vertex ( Fig. 11 ). Frons concave and strongly crenulate ( Fig. 11 ). Flabellate antenna longer than the total height of the head.Elytra very short, brownish-red; metathoracic wings with a wide, transverse, black median band ( Fig. 12 ). Fore and middle legs completely orange reddish with abundant brown pilosity. Posterior legs black, except the dorso-anterior part of the femora, which is orange reddish. Abdomen brownish with some parts darker.

Biology: Ripiphorus valdivianus is endemic to Chile. This species was recorded by Philippi (1861) visiting Eryngium paniculatum Cav. & Dombey ex F. Delaroche. It has been recently recorded from shrublands dominated by Fabiana imbricata Ruiz & Pav. and Baccharis surround- ed by temperate trees such as Nothofagus glauca (Phil.) Krasser and N. obliqua (Mirb.) Oerst. (V. Valdés and R. Varela pers. comm.).
