Mod. L. apicalis  apical, of the tip  < L. apex, apicis  point, extremity.
● "ACANTHIZA APICALIS.  ...  Distinguished from A. Diemenensis, A. pusilla, and A. Ewingii, to all of which it is nearly allied, by its large size, by its larger and rounder tail, by the broad and distinct band of black which crosses the tail-feathers near their extremities, and by their being largely tipped with white." (Gould 1847) (Acanthiza).
● "MOHO APICALIS  ...  I avail myself of the opportunity of characterizing the species, and have assigned to it the name of apicalis, from the circumstance of all but the two middle tail-feathers being tipped with white" (Gould 1861) (‡Moho).
● "MYIARCHUS APICALIS  ...  caudæ nigricantis rectricis externæ pogonio externo et ceterarum apicibus latis flavido-albicantibus" (P. Sclater & Salvin 1881) (Myiarchus).
