World distribution. Argentina and Chile . Chilean distribution. From Coquimbo to Los Lagos region ( Fig. 70 ). Altitudinal range. From coastal to precordillera ecosystems (5– 1,200 m .a.s.l.). Biology and notes. Macrometopia atra is mainly associated with Mediterranean scrubland, Valdivian forests or Nothofagus forest although is it also likely to be found in open areas (R. Barahona-Segovia, pers. obs.). According to Smith-Ramírez et al. (2005) , this species visits flowers of the endemic trees Eucryphia cordifolia and M. planipes in Chiloé (R. Barahona-Segovia, obs. pers.). Conservation status. LC; EOO = 123,128 km 2 , AOO = 116 km 2 , 25 subpopulations and 27 localities. Genus Sterphus Philippi, 1865 Sterphus Philippi, 1865: 737 .
