Ciao,

# 3028 ♂ captured at an altitude of about 740 m. in Cne : Songieu (Dépt. Ain - France) - 14.06.1995
# 2417 ♀ captured at an altitude of 930 m. in Cne : Lac-des-Rouges-Truites (Dépt. Jura - France) - 30.05.1992


The keys : viewtopic.php?f=370&t=21255 & viewtopic.php?f=370&t=21257 lead us to the tribe Tenthredininae.

I have in preparation a key of determination (rehandling of that of Zhelokhovtsev) of genus and sub-genus of this tribe, this key is not finished (could I all discriminate them ?). Thus I will not expose this outline.

These capture are Tenthredo s.l. , it belongs to the sub-genera Maculedo or Tenthredella.
The abdomen is black and yellow, and the antennas are entirely black, it thus acts of Maculedo.
One uses now the keys of Benson, and one observes :

♂ - The tibiae 3 is infuscate apically (if not : Maculedo diana)
♀ - Is not such as : 2nd, 3rd, 6th and 7th tergites are flecked with yellow laterally (if not : Maculedo diana)

Finally :
Tenthredo (Maculedo) maculata Geoffroy 1785 ♂ & ♀ Che vivono in Italia (T.(M.) diana anche)
Saluti.

Capture 3028 ♂

Ciao

This short message to take date, before sending complete.
This capture is (for me ...) a Maculata ssp. n.
because :
- Hindwings with marginal vein (see photo above).
- Abdomen dorsally with the yellow almost white, this colouring is absolutely identical to that of the alive insect.
- Trochanters 2 & 3 and coxae 3 black.
- Tarsus 3 with tarsomere 1 strongly swollen.

Saluti.
D & JP Balmer

I forgot !
- Metapleuron and mesopleuron black.

Ciao Jean-Pierre, volevo personalmente ringraziarti per i tuoi post , che sono veramente dettagliati, direi perfetti.!!
Ho notato che ricevono poche risposte.....ma ho capito anche il perchè.
Semplicemente non c'è nulla da aggiungere.
Grazie ancora per il tuo importantissimo e competente contributo.
Conocevo pochissimo questi imenotteri, ma grazie a te ho imparato ad apprezzarli ed a capire quali sono i caratteri discriminanti!!
Ritengo che il mio sia anche il pensiero degli altri utenti del forum.
