Collinsa acutalis (Walker, [1866])
1) OD : Pyralis acutalis Walker, 1866, List Spec. Lepid. Insects Colln. Br. Mus. 34: 1523, described from Indonesia - https://www.biodiversitylibrary.org/item/120100#page/829/mode/1up
2) https://www.inaturalist.org/taxa/1104375-Collinsa-acutalis
3) http://www.pyralidsofborneo.org/index.php?collinsa-acutalis-walker1866-1865-plate-3
4) On the Picture-winged Leaf Moths from Chittagong University Campus, Bangladesh Rayhan, et al, TROP. LEPID. RES., 32(2): 118-126, 2022 lists hamifera & acutalis as separate species, & also refers to the “acutalis group”
Rhodoneura hamifera, Moore, [1888] 1887 is a synonym – refer Pyralids of Borneo, also refer to this article on hamifera - https://archive.org/details/tlsj-lepid-57-4-301/mode/2up?view=theater
Lepindex classifies acutalis under Rhodoneura, but this may not be updated. It also lists hamifera as a junior subjective synonym
Hampson considered hamifera under Rhodoneura nitens
SS: Moths of Laos, Pl. 93 lists Rhodoneura fulvipicta and Rhodoneura hamifera as valid species. I'm not so clear about how to separate Collinsa acutalis (Walker, [1866]), Rhodoneura fulvipicta and Rhodoneura hamifera. I also have a similar individual from Eaglenest, which I will upload, but I have not been able to identify this reliably.
JD : R. fulvipicta does not appear to have the C-shaped apical streak on the FW, rather it is mentioned in the OD as oblique. The image on MON Part 5 Pl 139/23, fulvipicta does not match my observation. See my notes in observation 286007.
Considering that Moths of Laos (2019) & Reyhan et al (2022) are the latest publications & these consider hamifera & acutalis as separate spp., then this should be either of the two. The OD of acutalis does not mention any apical white markings. The images of hamifera in Reyhan et al as well as in Moths of Laos have the C-shaped white apical marking on FW as described by Reyhan, & this is present in this observation. This marking is also seen in Choi (https://archive.org/details/tlsj-lepid-57-4-301/mode/2up?view=theater) & Pyralids of Borneo where these two taxa were considered as synonyms. So this could possibly be C. hamifera.
JR: I would probably label this as C. hamifera, not acutalis. Agree with JD's justification!
SS: Agree with Rhodoneura hamifera (Moore, 1888)
