Only recorded for Arica y Parinacota region ( Fig. 180 ). Altitudinal range. From coastal to inland valley ecosystems ( 10– 500 m .a.s.l.). Biology and notes. Drioprosopa vockerothi is a species widely distributed in other countries and therefore, we propose that this species should be classified as Low Concern (LC). We do not know the flowers that this native species visits, the prey consumed by their larval stages, or other basic aspects of its biology and ecology. Conservation status. LC; EOO = 1,232 km 2 , AOO = 20 km 2 and four localities or subpopulations (see notes for justification). FIGURES 178–179 .
