Hello,

In 03/08/2023 I collected a Tachinidae specimen from an urban park in Athens. Using Moschweb and the book of Cerretti (2010) concerning Italian Tachinidae, I managed to key it out as Zeuxia tricolor (Portshinsky, 1881). However, I would like your opinion too concerning the validity of this identification. Below, I present the characters used for reaching genus and species level, plus some photos.


Generic ascription [Moschweb]:

1) Eyes bare.

2) Parafacials entirely hairy.

3) Facial ridge hairless.

4) Posteroventral part of the occiput with a mix of black and whitish hairs.

5) Arista pubescent.

6) Palpus black.

7) Tegulae black and basicostae reddish.

8) Second costal segment pubescent below.

9) Cell r4+5 open.

10) Abdominal tergites 3 and 4 without median discal setae.


Specific identification (Cerrutti):

1) Eyes bare.

2) Proepisternum bare.

3) Syntergite 1+2 without mediomarginal bristles.

4) Median depression of syntergite 1+2 reaching the posterior margin.

5) Parafacial hairy.

6) Fronto-orbital plane of the female with 2 proclinate orbital bristles.

7) Female postpedicel 1.2-1.5 as long as pedicel.

8) Female palpus with distal part thickened but not swollen.
