J'arrive à
Lauxania cylindricornis mais la taille ne colle pas : 3 mm. contre 4,8 mm. pour mon exemplair.D'autre part la
base de l'aile n'est pas noirâtre ni la couleur corporelle d'un noir brillant,
J'ai donc dû me tromper quelque part.Pourtant j'arrive bien à l'alinea 6 mais le premier segment antennaire n'est pas plus court que le second, ce qui éliminerait le genre Calliopum.
Head of normal shape. Ocellar pair of bristles
present. ........................................................ 2
Ocellar pair of bristles placed on ocellar
triangle, behind front ocellus, and not
outside a line connecting outer edges of
front and rear ocelli. ..................................5
5 Face usually shining black, broader and
more convex (occasionally orange-brown).
Frontal stripe narrow, not (or very little) wider
than the ocellar triangle, always
differentiated from the rest of the frons (from
at least some points of view) by microscopic
dust or pile. 3rd antennal segment longer
and narrower. ............................................6
6-First segment of the antenna as long as or longer than
the second. Wing
base distinctly blackened. Shining
black species. Length 3 mm. ........................................
