Cave racers mating

In 2000, in Dark Cave at Batu Caves in Malaysia, I saw 3 cave racers mating.  I put some photos on my cave website -

The cave racer used to be classed as Elaphe taeniura but is now known as Orthriophis taeniurus. It inhabits limestone caves all over Asia ranging from China, down through the Asian mainland to Malaysia and Borneo. It is commonly seen in caves. There are around 10 species.

I wrote a note on the mating racers in The Malaysian Naturalist, 2002, Dec, 56(2)8 -

In 2023, on 25 Oct The Thaiger (in Thailand) published this article "Explorers ‘rattled’ with excitement as rare Blue-tailed Cave Racer snakes spotted mating in Krabi". It records two Blue-tailed Cave Racer snakes mating in a cave in Ao Luek district, in Krabi province, in southern Thailand. 

The article describes these snakes as endangered and a rare protected species listed in CITES (Convention on International Trade in Endangered Species). However when I looked on CITES, Elaphe taeniura is not listed in the CITES Appendices, nor are other species of Elaphe genus. Orthriophis taeniurus is not mentioned either.
