Endotricha sp (D?)
This moth is only 10mm in ws and I have tentatively identified it as an Endotricha. There is one similar in RCK's thesis, sp D.
The nearest match I can find in my reference books is E. rogenhoferi but that is endemic to the Canary Islands and almost 2x the size!!
Suggestions appreciated.

This looks more like Pyralis manihotalis (a cosmoplitan detritivore and scavanger) that I didn't record during my thesis because it's associated with warehouses and slaughterhouses (it's larvae will feed on decaying meat fragments - we had lots emerge from a shipment of turtle plastrons intercepted by AFCD last year, given to KFBG to do morphometirc analysis; it came with literally hundreds of P. manihotalis larvae as additional cargo). However, your stated size is a little small, and it looks a little chunkier as well.  One to follow up.

Pyralidae, Pyralinae, Pyralini (not Endotrichini)

Roger, Slamka's Pyraloidea of Europe Vol 1 says Pyralis manihotalis has a ws of 24-37mm, male smaller than female. The larvae feed on animal detritus,
has also been reared on bat guano!! Its European distribution is only 2 records, 1 from the the Canary Islands (originally confused with Endotricha rogenhoferi !!)
and 1 from Dundee (larvae) in 1943 in produce imported from India. Its global distribution is given as Tropics, Far East, Japan, Pacific Islands, USA (Florida). I was
amused that it states: Unmistakeable, no confusion species. The plate of the male is of a Malaysian specimen taken by Kevin Tuck. As the ws is 20mm at 1.5x
normal size, this indicates the true ws ought to be about 14mm so my moth is still on the small side. The text quoted ws appears to be inaccurate.

I still think this is manihotalis. Stunted (dwarf) forms are always possible - I remember seeing dwarf Silver Ys in the UK that were only half the wingspan of the quoted measurements.

Found this small moth in an office in Sheung Wan last week.
