Ecoregion.

Northwestern Andean montane forests [NT0145].

Remarks.

This taxon has been reported from disjunct localities that are widely separate, at altitudes ranging ca. 700-1500 m. The external morphology is, however, very similar. Miquel (1998: 186) remarked that Simpulopsis (Eudioptus) willineri (Hylton Scott, 1967)-known from Paraguay and northern Argentina-strongly resembles this species. Cuezzo et al. (2013: 184) had it as synonym of Moricand’s taxon. The species might also be expected in suitable habitats in Bolivia. Breure (1978: 235) already pointed out that this disjunct distribution needs further investigation and molecular research may show either convergent evolution or a species complex.
