No! I just said it's of very similar body shape (including head, antennae etc). Thus, both should belong to the same genus in my opinion. Note also that Gressitt compared R. elongata to his "longissimus".

Of course, they do not much well the type species of any of these genera (ie neither R. quadricolor nor D. nigrofasciatus), but it is another issue.

Do you think Rhaphuma elongata Gressitt could be the same species ?
Here a specimen and the original drawing.

The specimen, which Sergi is showing us, is coming from NW Yunnan, just a few kilometers (10?) from the Xizang border. I collected the same species there as well (together with the guy from whom Sergi bought it) and it is Rhaphuma, very similar in body shape to eg. R. elongata Gressitt.

Most probably, it was described by Pic as D. longissimus and accidently also by Gressit under the same name several years later.

The type series of Gressitt belongs definitely to the same species as pictured by Sergi.

ok, Demonax longissimus Pic, 1914 which could be a Rhaphuma as I wrote here.
Xavier Posted - 25/01/2016 : 20:36:56
what is R.longissima Pic ? I do not find it...
horshehden Posted - 25/01/2016 : 19:54:07
Or R. longissima (Pic, 1914).
Xavier Posted - 25/01/2016 : 12:26:27
Rhaphuma nigrolineata Pic, 1915 for me
