Je continue la clé Tolkanitz et j’arrive sans trop de difficultés
86-Facial carina ventrally not joining to lower margin of
88-
3rd–5th
96-Legs blackish brown or black; usually fore tibia and tarsus paler or apices of femora and
98- Temples in lateral view usually shorter than
Facial carina distinctly elongate, subparallel-sided. ok
100- 1st and 2nd metasomal
101- Usually large-sized; length of fore wing 10.0–14.0 mm.
Body black with grayish setae;
101- Usually large-sized; length of fore wing 10.0–14.0 mm. -> 9,9mm
Body black with grayish setae ok
103- Facial carina distinctly elongate, ok
gradually narrowed downwards, ok
with straight upper margin, black,
with more or less wide yellow lateral margination (Fig. 6, 3). ok
Body black, with long grayish setae. ok
1st–5th metasomal
or black with yellow stripe along
2nd–5th
or interrupted in middle, Fig. 10, 7).
Wings weakly infuscate. ok
Hind tibia black. ok
10.0–12.6.
Donc tous les critères correspondent au M. citratus de Tolkanitz
Reste l’alternative fuscipennis
- M. citratus =
coins postérieurs des T1-3 jaunes -> mais un très faible petit point brun jaune aux coins postérieurs. NB que Tolkanitz dit T2-5 jaunes
et marge
-M. fuscipennis =
marges
ok(parfois interrompue centralement sur T5), marge
Reste à savoir si la séparation fuscipennis <->citratus est avérée.
Pour moi j'en resterai à M. citratus seule sp mentionnée par Tolkanitz et qui correspond très bien.
Qu'en pensez-vous?
