GENERIC CHARACTERS OF MONODONTOMERUS
The following combination of characters will distinguish Monodontomerus from all other genera placed in the subfamily Monodontornerinae :
- Antennae 13-jointed (scape, pedicel, one ring joint, seven funicular joints, and three club joints) ; flagellum cylindrical, not or only thickened toward apex ;
- occiput margined ;
- scutellum with a distinct transverse furrow ; postscutellum usually with a median carina ;
- propodeum with a triangular or subtriangular depression medially, the depression broadest anteriorly, bisected by a median longitudinal carina, the two sections of the depression more or less foveolated ;
- posterior coxa large, with a more or less prominent protuberance near apex on the inner dorsal margin ;
- posterior femur rather broad, with a single tooth on ventral margin beyond the middle ;
- posterior tibia with two moderately long, unequal spurs located at the apex ;
- fore wing extending beyond apex of abdomen ; marginal vein usually about half as long as submarginal ; postmarginal vein shorter than marginal ; stigmal vein at least a little shorter than postmarginal; abdomen sessile, never strongly compressed or depressed, and approxi- mately as long as head and thorax ;
- posterior margins of tergites (except sometimes the third tergite) not emarginate ;
- ovipositor always prominently exserted.
Bon en regardant la clé le Boucek (1964)...
- le fémur n'est pas très large avec une ligne de petites dents ventralement et tibia arqué > élimine Podagrion
- l'abdomen n'a pas de long pétiole >elimine Thaumatorymus
- on ne voit pas si la veine stigmale est épaisse, mais le corps n'est pas marqué de jaune > élimine Megastigmus
- le mesepimeron n'est pas incisé sur sa marge postérieure >élimine Toryminaeles Torymini (Grissell, E.E.,1995) http://www.canacoll.org/Hym/Staff/Gibso ... msslpl.htm http://forskning.no/sites/default/files ... s_None.jpg
- l'abdomen est cylindriquement convexe et je devine une dent sous et à l'apex du fémur : http://www.morphbank.net/?id=228756
> Ce qui va très bien pour Monodontomerus
