Dart

One of the difficulties I encountered when trying to identify this specimen was that in the captions of one or two Darts shown in Philippine Lepidoptera it says "Potanthus also has obvious apiculi or hooked tips on its antennae" (slightly paraphrased to correct singular/plural typos). I am not saying that is wrong, but I have been unable to find any reference to help me with that statement. I only mention it because in most of the Philep pictures, the apiculi can be clearly seen, but in a few pictures, they are not visible. Of course, I understand that this could be down to lighting conditions or angle of view making the apiculi hard or impossible to see, but here's the real problem. The wiki picture of Potanthus serina which is, in my opinion, very high quality and can be enlarged considerably by clicking on the "More details" tab, shows rounded ends on the antennae. There is no room for error here, there is absolutely no doubt that there are no apiculi on those antennae. So, where do I go from here. My two most trusted sources are at odds with each other on a very important identifying feature of the Potanthus. This is particularly relevant to my efforts at identification because as you can clearly see, even on my very amateur photos, there is not one apiculus in sight. So I must leave it unresolved for now. I can see that the success or failure of my identification hangs on the antennae more than any other feature which may be in question.
