When I chanced upon this Mantis nymph, probably a sub-adult, I tought this looks rather unique as not only it was small in size but the the colouration/markings of the abdomen makes it looks a bit like Planthopper. And later on when I was able to get the ID, naturally I tried to look up for more info about this species and was not surprised that there are hardly any pictures about them and not much is still known about the species. Furthermore, a local friend who has been frequenting this location for nearly 20 years have never encountered this species before!
Update, pic of the adult :
''Epsomantis'' is a monotypic genus of mantis in the new family Nanomantidae. It represented by the single species, ''Epsomantis tortricoides''.
