Difficult to say. This species (and other congeners) was studied by Dillon & Dillon (1948) who described as subspecies a lot of forms.
Further investigations on several of the groups studied by these American entomologists has revealed a lot of coarse errors, misidentifications, wrong valuations, etc., so that nearly all Dillon's taxa have been invalidated. I do not know the taxonomic situation concerning Olenecamptus bilobus but
- by studying my materials from different localities (Indonesia, New Guinea, Japan) I have seen that the correspondence region/subspecies is very doubtful
- the book of Chinese Longhorn provides pictures of Chinese specimens belonging to subspecies from Taiwan, Vietnam, Philippines, New Guinea, etc.
- the site Lamiaires du Monde considers all these form as synonyms.
- Last but not least, the typical form came from "Oriental islands", actually an unknown land.
Waiting for more serious investigations, I propose to leave this form as "Olenecamptus bilobus". |
