Hi all.
Slightly larger than your typical Pterolophia sp and inbetween the size of that and Moechotypa.
It's been bugging me for a while, literally!
Data: 12-2012 - Ambon Island - Indonesia |

Rhytiphora distincta (Pascoe, 1864) ? Shape of pronotum is not the same...
and 413 species in the genus !!  (cf. Titan database). |

| Yes that looks similar, thank you very much, it is riddled with small punctures. |

It is really very similar; however, a female.
The valid combination is Prosoplus (Escharodes) distinctus (Pascoe, 1864)... Let us draw a veil over the delirium by Slipinky & Escalona (here). |

O so the genus Rhytiphora is now Prosoplus?
Who decides these taxonomic changed and without peer reviews...I hope not  |

Rhytiphora and Prosoplus are two very distinct genera.
- Rhytiphora shows elongated body and antennae fringed by dense hairs beneath. The habitus generally reminds Saperda carcharias.
- Prosoplus shows stout body and antennae fringed by sparse hairs. The habitus reminds the genus Mesosa.
This for a superficial recognition, but there are further differences:
- antennae thick (R.) or fine (P.)
- antennomere III longer (R.) or mostly shorter (P.) than IV
- eyes divided or strongly reniform (R.) or reniform (P.)
- prosternum anteriorly rounded (R.) or truncated (P.)
- mesosternum anteriorly rounded (R.) or truncated (P.)
These two genera were considered separated by all entomologists since 1853... until Slipinsky & Escalona (2013) - two entomologists with general interest on Beetles and without previous papers on Cerambycids - wrote this synonymy in a self-published book.

Coming back to the identification of this species, I think that it is Prosoplus (Escharodes) strenuus (Pascoe, 1864), described from Ambon.
It differs just from distinctus  in the less pronounced dark markings and other features. |

Interesting topic, Xaurus.
Pascoe and Breuning based their taxonomy on morphological features of the body and of few specimens, overlooking genitalia, biogeography and, mostly, variability. For example, P. distinctus and P. strenuus might be two subspecies.
I think that we are in the condition to further improve their study.
Articles like yours and by Andre Skale are a good way to drive a serious scientific research... PC and Delta-software belong to the Paris Hilton's of the Entomology.
