I think it is Chloridolum (Leontium) jeanvoinei (Pic, 1932), originally described as a green variety of L. lameerei. Even if I have detailed descriptions, it is not easy for me to understand the real differences of these species...
Indeed: it is not easy. According to Gressitt & Rondon (1970), this species is just characterised by antennae reddish at the apex... a character that Plavilstshikov (1934) did not mention either...
