Hi everybody, I found this Tachinid yesterday in the dunes (Netherlands, near Castricum), in a dry open area with some shrubs and small bushes. I'm having some problems with identifying it. It stops at Nowickia sp. or Peleteria sp. I think it is Peleteria rubescens but on Waarneming.nl they think it's Nowickia (I asume N. ferox). Which one is it? Please help!      I have more photo's if necessary. Edited by Iolaire on 24-08-2009 19:10 Best regards, Iolaire |

Keep the courage of your convictions - it is Peleteria sp. (the 2 distinctive bristles between the eye and mouth are clearly visible)  Not sure about the species though because I see them so rarely here.

Thanx Chris! 3 species known in the Netherlands, of which 2 are very rare (P. ferina and P. popelii). I'm positive it's P. rubescens because of the deep black antenna. The other 2 species have some yellow or red in the antenna, mainly on the 2nd antennasegment. Also the space between the eyes and antenna (cheeks?) is much wider (much wider than 3rd antennasegment) in P. rubescens than the other 2. The only thing that is questionable is the colouring of the scutellum: this should be brownish yellow, where it is more dark brownish red in my pictures. Best regards, Iolaire |

rubescens is OK, but the information on the other dutch species is not, We have only one Peleteria + 1 record of ruficornis from 1901. Where did you get the other information ? Theo |

Hi Theo, You are right (of course!). I got the info from your key (1992) but I didn't notice that the 2 rare species mentioned are not known from the Netherlands. My mistake. Thank you for confirmation and feedback. Best regards, Iolaire |

Right That key is so old, I had forgotten about it. Sorry. The NL-symbol there refers to the couplet of species. If you check the dtuch checklist or faunaeur.org, you can see the correct results. Sorry for the confusion I created some 15 years ago. Theo |

That's alright. That 'old' key still got me to Peleteria, so I figure it's still in some kind of working order. I'll look for that Dutch key you mentioned. Is that a key to all the Dutch Tachnids or just the larger ones? Thank you for replying.
Best regards, Iolaire |

It was not a dutch key, but a dutch checklist. The one written by your webmaster truly some 5 years ago ! Theo |
