10mm. The species is slightly smaller but of identical facies to macrodonta.
It belongs to a group of three, as mentioned under macrodonta, where
there is a pair of coremata in the male abdomen between A5 and A6 (gertae
and the New Guinea species, which has a much smaller pair between A4 and A5) or
between A4 and A5 (very broad, large in the Sulawesi species). The tegumen
shoulders below the uncus are much broader in gertae than macrodonta
or the other two corematous species, and the saccular hair pencils arise from
two relatively basal but small oblique patches of bases joined by a narrow zone
of them along the ventral margin. The genitalia appear to be somewhat more
darkly sclerotised than in congeners.
