Evans state of C. bromus, that the female have 1- 2 HW spots.
this was taken to meant that the Male do not have HW spots.
C&P 4's key actually do not state the sex, indicating that the male may also have HW spots.
Yutaka website shows a male with two Hw spots.The female with one. https://yutaka.it-n.jp/hes/93320001.html
Caltoris bromus bromus. Antennae with prominent pale areas.
[/I]FW with two cellspot usually large, SUbapical spots large often two, sometime three.
HW dark brown overlaid with ochreous scales ,generally contrasting little with the FW
Two fieldshots in which the HW have multiple spots are intriguing .
They appear to be Caltoris, with pale areas on the antennae & largish spots.
They also do not match any other genera.
PS. All the males with UnH white spots have the UnH ground colour very dark brown as in C. cahira.
As stated earlier, cahira is specifically stated to have no UnH white spot.
This raise the question if it is possible that Singapore have a unique population of C. cahira that may have UnH spots
Or perhaps it is an endemic new species.
This question can only be answered if some specimens are taken & the genitalia examined or DNA analysis is done.
Based on the key of the reference text, these are considered to be C, bromus . https://yutaka.it-n.jp/hes/93320001.html https://yutaka.it-n.jp/hes/93300010.html

Have this male Caltoris eclosed this morning. Is this Caltoris bromus? It has one obvious white spot in the hindwing, and may be a second one (much more obscure than the first one).
The FW spots are usually large, the subapical more often two.
The Hw spot here is in space 2.
Male more often have no HW spot, while the female often have two in space 2 &c 3.
