Male of vietnamese long Exocentrus some similar to E. brunnescens Holz.,1995 but not sure, certainly 5 mm, Sa Pa reg., Lai Thiau prov., 1 km W Tram Ton pass
I don`t think so.. Gabitually it`s more similar to hupehensis for me (about shape of pronotum and body, thoracal spines, and design of elytral pattern too despite the fact that it's some shabby really) What do you think of that idea?
