Chilean distribution. From Metropolitan to Los Lagos region ( Fig. 103View FIGURE 103).

Altitudinal range. From coastal to inland valley ecosystems (5– 500 m.a.s.l.).

Biology and notes. Valdiviomyia nigra  is associated with native forests, especially with the floral resources E. cordifolia  (C. Smith-Ramírez, com. pers.) and A. meli  (R. Barahona-Segovia, pers. obs.). The specimen collected in “ Santiago ” could potentially be a labeling mistake. New specimen needs to be collected to corroborate this locality.

Conservation status. EN under B2ab (iii) using AOO = 20 km 2 and five localities (or subpopulations); EOO = 1,312,585 km 2.
