Hi Francesco, I found this one in a highland in Pahang, Malaysia.
Body length about 15mm.
I have a top view too. Will upload next.
Thanks

A Glenea-species, very similar to G. t-notata Gahan, 1889.
I did not know it reaches Malacca. |

Thanks, Francesco.
Not Malacca but Pahang. See map :) |

| Oh maybe you meant Malaysia, not Malacca. |

I meant Malacca according tom the old sense (= Malayan peninsula) in opposition to Borneo.
However, this species seems new for Malaysia. |

Yes, Malacca was where it all began, but afaik, there's no references of it representing Malaysia though. Whenever we hear Malacca, we always refer to the State of Malacca (Melaka) :)
Oh by the way, this beetle was in that pose for more than ten minutes, on the underside of a leaf. Any idea why? |

Another interesting topic!
Some time ago, I received from Mr. Ippei Murata the picture of this Glenea relicta Pascoe, 1868 from Hokkaido.
I never noticed this fact, the body position is the same. No idea.  |

Perhaps the species above is Glenea sulphurea Thomson, 1865.
It is a close match to this specimen from Sabah.

G. t-notata Gahan, 1889 and specimens above have different antenna .

...but Thomson said nothing about colour of antenna. |

| About the position of the above insects, I think that is a sexual attraction position by pheromones spreading. |

At least 4 species have a very similar pattern (but maybe more ! ):
- Glenea citrinopubens Pic, 1926 Vietnam, China(Yunnan), Laos
- Glenea flavimembris Pic, 1943 Java
- Glenea sulphurea Thomson, 1865 Cambodia
- Glenea t-notata Gahan, 1889 India(north-east)
I don't know if some of them are synonymous, but I think that all this group should be revised.
Orionmystery's specimen is probably Glenea flavimembris Pic, 1943, but Dan species fits with none of the four species listed above.

I have a photo of two specimens (from peninsular Malaysia) from the BMNH identified by M. Lin (as G. sulphurea), which shows that there is a little variability in the black pattern on the pronotum and the elytra. My specimen from Borneo fits into that pattern of variability. The specimen posted by orionmystery is also G. sulphurea! Are we at the point where every small variation in the pattern on a beetle deserves a different name ( this question is for Pic and Breuning, especially  ) . In the past, a high percentage of species were described from one example, and the author of that species usually did not have an opportunity to examine similar species. This is just my opinion.

I give my opinion just by comparing with the HT picture of Glenea flavimembris Pic, 1943 from MNHN; and it is a species from Java. It is more logical that it should be this one, rather than the one (G. sulphurea) described from Cambodia.
But, as I wrote above, I do not know which sp. are synonyms or not. |

Thank you Gerard. For me, these species are the same.
Compare the distribution and variability to a species such as Glenea relicta!! |
