Eccentric creature from N Sumatra, Aceh st. 16 mm, female. I don't know what is E. sumatrensis. In the case of the rest of they species all abstruse for me too Help please
your spms fits E. invitticollis Breuning, 1961 very well (type in ZMB), I don't know E. sumatrensis, interesting to check both, maybe a further synonymy
