Hello
I have this beetle coming from: Aseki, Morobe, P.N.G., january 1994
I have the feeling it's a morimopsini, due to the spines, bulbous pronotum, seems apterous... But I couldn't find anything close on my searchs... Perhaphs the genus Protilema, Echthistatodes or Petromorphus are close relatives.... On lateral view, this beetle slightly reminds of some predatory orthoptera like weta.
Let's see if someone can help.
Edition: Talking about lateral view:

What is the length?
I have a pair of Spinocentruropsis papuanus (Lamiini, similar to Mesechthistatus spp.) from PNG that are over 25mm. Morimopsini are rather small... usually under 15mm but there are exceptions. |

I think it belongs to Spinospasma Breuning, 1970, only 1 sps is know S. hynesi Breuning, 1970, I have 3 spms and maybe only one belong to S. hynesi, there is only very few material known, and I think this group have a wide range of variations and a remarkable sexualdimorphism too.

Hello
Sorry, I forgot to put the size. It measures 40 mm.
So yes, know you say it, it probably belongs to the Laminii tribe. The mentioned Mesechthistatus are alike although some features doesn't match. In the old world cerambycidae web and the titan database the only laminii cited for Papua are Metaperiaptodes wich clearly doesn't match and indeed Spinospasma hynesi, but actually I'm not capable of find any image of the habitus of that species to check so for the moment I stick to the comment of Xaurus.

for the moment the nearest species is S. hynesi indeed, I have seen a type picture in past and compared my spm, I'll find this soon.
Please Dan can you show us a picture from your Spinocentruropsis papuanus maybe this is the same like Protilemoides bürgersi Kriesche, 1923 |

Spinospasma hynesi Breuning, 1970. Original description.
All features from descriptions, except length, fits with the specimen above. I have not seen the type specimen which is at MNHN-Paris. |

The species has been rightly transferred to Phrissomini.
According to the current systematics (used here), apterous Lamiini does not exist. Lamia is a winged species!

P.N.G.: Spinospasma hynesi ?
