I believe your mantid is a Spiny Flower Mantis nymph in the genus Pseudocreobotra (Mantodea: Hymenopodidae). It is either P. ocellata (my guess) or P. wahlbergii. The two species are very similar so I can’t say with certainty. Coloration among nymphs seems quite variable, ranging from white to brilliant pink, but there are always some areas with a greenish tinge. The adults look quite different, but are as or even more spectacular. Both species are popular among mantis breeding enthusiasts so there are a lot of photos on the internet. If you type the genus name into the “What’s that Bug” search engine you will find at least four previous postings showing both nymphs and adults. Regards. K
