Thysanoidma octalis

SS: I don't think this is Thysanoidma octalis. Observation MOI-pqy218 is also similar. For me there is also confusion whether this species displays sexual dimorphism. The OD description is that of a male. The description of Hampson, FBI, vol. 4, pg. 202 is the same description, but mentions that this is a female.

Needs investigation.

JR: I think the species T. octalis is not sexually dimorphic in wing pattern. For instance, compare the MOI observation pqv 468 which is a female, and cm 050 which is a male- both with similar wing maculation. However, after a careful analysis, I have found that there are two broad categories of the so-called T. octalis morphotypes . Firstly, the wing shapes- narrow winged: this observation and MOI pqy 218. Secondly, the gap between the antemedial and postmedial lines on the inner margin/ dorsum of forewings (widely separated in T. octalis original illustration, and MOI bz 818; and closely situated in this observation, as well as MOI pqy218, and MOI pqx 945). I am not considering ground-color that is mostly dark and light here, probably environmental. If we consider all these variations into account, the situation is super messy here. Either we are dealing with a group of complex species, or all corresponding multiple morphs of T. octalis. In my opinion, the second one seems like more plausible hypothesis to go with for now.
@SS, I am sharing a photo with you by email to illustrate on this further.
SS: Ok let's go with this. But I will add a note to the species page.
