Finally, this species did not belong to any known genera and I have decided to describe it as Pseudobrachyhammus sulawensis n. gen. n. sp. The figured specimen is a female paratype.
Nice ! First I though I have a similar spm in my collection from Peleng Island, but there are some differences indeed ...so, I have another problem: if you want to describe another species in this genus how to differentiate this from P. sulawensis ??
