World distribution. Chile . Chilean distribution. From Valparaíso to Los Lagos región ( Fig. 87 ). Altitudinal range. From coastal to highland ecosystems (14– 2,000 m .a.s.l.). Biology and notes. Stilbosoma rubiceps is associated with native forests and its plant species such as M. exsucca (J.H., A.W. and A.M. Skevington pers. comm. from CNC). Nonetheless, organic crops such as Persea americana Mill. or Helianthus annus L. are also visited by this fly (Fabián Soto and Nicolas Riffo, CSP records respectively; see Fig. 83 ). Also, this fly visit flowers of the native E. paniculata (Josefina Arce, CSP record; Fig. 82 ). Conservation status. LC; EOO = 219,379 km 2 , AOO = 92 km 2 , 21 subpopulations and 22 localities.
