Post 43 No. 2. Tentative ID. Perixera gaeta , Geometridae. Sterrhinae. Cosymbiini. Range Sundaland, Sulawesi.
This was in an earlier post only tentatively thought to be Erythrolophus fascicorpus.
Although the HW has a black discal ring spot, the abdomen is not black-banded as in Erythrolophus.
However, among the Perixera is a good match.
It matches the image of P. argyromma (image large enough to compare accurately) quite well , all the black dots on the FW as well as the medial dark band.
The HW discal spot is white rimmed with black & may be almost black as stated in the text of argyromma.
P. argyromma belongs to a suite of 3 almost identical species.
P. argyromma is montane.
P. argyrommoides is a Bornean endemic.
This leaves P. gaeta .
