Agrilus abstersus Horn 1891

(Figs. 51–53)

Only nine specimens were examined that are attributable to this species, all from BCN: 10 km S Valle de Trinidad, 2-VII-81, on Prosopis, W.F. Barr (WFBM); 40 km E, 0.8 km N El Rosario [30.075340°, -115.346733°], beating Prosopis glandulosa var. torreyana , 25-VI-80, Bellamy & Westcott; Cataviña, beating Prosopis glandulosa var. torreyana , 28-VI-80, Bellamy & Westcott (both RLWE); 7 mi S El Mármol, 18-VI-38; Chapala Dry Lake, 21-VI- 38, both Michelbacher & Ross (CAS). The latter two localities, three specimens, are part of Van Dyke’s (1942) type series of A. peninsularis (q.v.). Elsewhere in Mexico A. abstersus is known only from Sonora, Sinaloa, Puebla and Oaxaca. However, it belongs to a difficult group of species and the southern records could refer to other species. In the U.S. it is known only from Arizona, where it has been reared from Acacia greggii A. Gray (Fabaceae) and Castela emoryi (Gray) Moran & Felger (Simaroubaceae) . Adults have been collected on other leguminous trees and a species of hackberry ( Celtis sp., Ulmaceae ).
