Guangxi
The colour pattern in elytra reminds that in Rh. horsfieldi.
Any idea? |

Hi, Xavier. Thanks for the observation.
Rhaphuma falx looks pretty different to me.
Please, have a look here. It has a very long black line and one apical spot in each elytron. |

Yes, but in fact, you can see 2 black spots after the long black line on each elytra, no ? (on eol picture)
I see also similar black shoulders, bicolor antenna and blackish hinf femora. But, may be I'm wrong  .
I add one of my specimens from Laos which shows some colour's and pattern's variation :

nb 25 : Rhaphuma illicata Holzschuh, 1991 ; nb 26 : Rhaphuma falx Holzschuh, 1991 ; nb 31 : Rhaphuma brodskyi Holzschuh, 1992
It's better to compare with author's pictures. The last one seems closer to your species ? |

please look at the elytral apex - very spiny curved, the spm at: http://eol.org/data_objects/25339699 indeed is R. falx, Vitali's spm is quite different, and really near R. illicata Holzschuh, 1991, a spm from my coll (female) look at here:

| Well, I didn't see spines...I thought it was an effect of photography. |

I suspect, these might be rather hair tufts than spines in Rhaphuma falx. The pattern in elytra and antennae coloration of my beetle is like in Rhaphuma brodskyi indeed. I would vote for this species, but legs are light and pronotal spots are different in my specimen. There might be a series of similar species. Xavier, would you please send me a reference to the paper where you copied these drawings from?
Something went wrong with Xaurus' photo of a female(?) I should also have a female of the species I placed above. I'll try to make a photo tonight. |

Here is a photo of a female as promised. Hind femora are darker and spots in pronotum more rounded. So, it seems even more similar to Rhaphuma brodskyi Holzschuh, 1992 than the male above. I think it is this species. It was described from North Vietnam that is just next to Guangxi province where my specimen was collected. |

I read the original description of Rhaphuma brodskyi Holzschuh, 1992 (Thank you, Xavier), and in my opinion it fits well. The drawing in the paper has too high contrast and femora seem dark. That was the main reason of doubts as the beetles in the photos above have light legs. In fact it is written in the description:
“…Beine und Fühler einfarbig hell rotbraun, nur beim (male); sind die Fühlerglieder ab dem 5.Glied in der apikalen Hälfte schwärzlich;…”.
So, another new species for China? |
