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.
