Assessment rationale/justification
Though this species is rare in evergreen forests (Feeroz 2013, Feeroz et al. 2012) but its EOO and AOO are much larger than the threshold level of threatened categories. Moreover, it is tolerant to some degree of habitat destruction. It does not fulfill any criteria to qualify threatened categories. So, it is considered as Least Concern.
