Biology and notes. Thompson (1972b) comments that Notiocheilosia has a problematic systematic position because it has a morphological combination of characters that can be attributed to different tribes. Notiocheilosia nitescens is a native species, recorded visiting flowers of Amomyrtus meli (Phil.) D. Legrand & Kausel, and Myrceugenia ovata var. ovata (Hook. & Arn.) O. Berg (Smith-Ramírez et al., 2005) as well as E. cordifolia in Chiloé.

Conservation status. LC; EOO = 99,081 km 2; AOO = 44 km 2 and 11 localities (or subpopulations).
