Hoplocerambyx spinicornis and Hoplocerambyx severus.
We all know how distinguish them:
- H. spinicornis has a shorter neck and longer yellow (?) pubescence.
It is widespread from India to Philippines (here a female from Mindanao, 55 mm long) and Indonesia (Borneo, Sumatra and Java).
- H. severus has a longer neck and shorter silver pubescence.
It is widespread in New Guinea (thus, Indonesia and Papua New Guinea). Here a female from Irian Jaya (Indonesia) 64 mm long.
But, do you know how to really identify relatively small female specimens (38-40 mm long) coming from "Indonesia"?

Many thanks to both. 
It seems to me that the carachters of the neck (granulate = spinicornis, strigate = severus) are more constant.
So, both my small specimens belong to H. severus. |

a good feature (from above) is the transverse corrugated neck in H. severus vs. granulated neck in H. spinicornis mentioned in Gressitt (1959): longicorn beetles from New Guinea I.

Bonjour Francesco regarde sous la tète. Les dessins me semblent différents ?
Je n’ai qu’une femelle pour comparer. Mais les dessins sont identiques au male.
