Hi,
I need confirmation of this Dorysthenes buqueti.
Ling Cu, Ha Giang Prov., N.Vietnam.
BL - 31 mm.
Thank you in advance,

| The shape of the pronotum and the ratio of the antennal segments seem to correspond well to D.buqueti. |

The antennomeres are evidently 12: it should be D. angulicollis
D. buquetii (here the type) is rather different. |

Be careful with the number of antennal segments, Buqueti described by Guerin-Meneville has 12! (see attached text), moreover in many cases, I could observe in angulicolis the 11th and 12th partially merged (detail noted by Fairmaire himself).

You must be careful with ancient description.
Lameere, who saw the type, wrote:
Lameere, 1911: 331
Light brown (not pitch brown) ad antennomere III not spined internally.

| Ok Francesco, my point was about the number of antennomeres taken as speciation criteria. In any case, this genus is largely to be reviewed (description of some species largely based on unstable or irrelevant criteria). |
