Black-faced Percher

The genus name Diplacodes combines Diplax, a genus name derived from the Greek δίς (dis, "twice") and πλάξ (plax, "flat and broad"), with the Greek suffix –ώδης (-ōdēs, "resembling" or "having the nature of"). The name refers to the similarity of the genus to Diplax and Diplacina. The species name melanopsis is derived from the Greek μελαν- (melan, "black") and ὄψις (opsis, "face" or "appearance"), referring to its brilliant black face.
