Type data:
Holotype SAMA ♀ (missing) (coll.: ii.1936, J.W. Evans. Evans (1966) noted that the holotype was missing from SAMA), Hobart, Tasmania.
Introduction
It may not be possible to determine the true identity of this species which is only known from the female holotype, currently missing from SAMA. Hamilton (1980) noted that M. viridiceps Evans was preoccupied by Macropsis viridiceps Wagner since Wagner's name was published in April 1941 and Evans' in July 1941, giving Wagner priority. However, he did not propose a replacement name. Wagner (1941: 104) created his viridiceps as a colour variety of Macropsis glandacea Fieber. Under the terms of the ICZN (Art.45.6.4), a name published as a variety prior to 1961 is to be regarded as having subspecific status unless expressly given infrasubspecific status by the author. Wagner (1941) recognised three colour forms which he named "Forma typica = ulmi Scott", "Var. viridiceps nov." and "Var. mendax Fieb.". Details were given of the type specimens of all three varieties. Consequently, there was no express statement of infrasubspecific status and the three forms are recognised as subspecies. M. viridiceps Evans is therefore preoccupied by M. glandacea viridiceps Wagner.
