Just to give you some supporting info. for my opinion: if your have Rentz's (2014) book, the species he illustrates as Ellipsidion bicolor has all black legs, unlike your specimen. Under the name Balta bicolor, Rentz illustrates the same species as under Balta spuria, and these are not Balta bicolor, which isn't illustrated at all in Rentz's book! Ellipsidion species are robust and convex with fully opaque pronotum. Balta are small, slender and flattened, with transparent pronotal margins. Most Balta are nocturnal, but B. bicolor is diurnal, like the Ellipsidion species.
