I've came into several problems while dealing with Platystomatidae. Firstly, is there a key for Palearctic species of this family? And secondly, Fauna Europaea gives Platystoma seminatione (Fabricius 1775) with six subspecies while most of other online catalogs give Platystoma seminationis (Fabricius, 1775) - which of those is correct?

Thank you for any suggestions Wink

I'm no Latin scholar, but I suspect that seminationis is a noun (derived from the verb seminatio) in the genitive case. As a noun in apposition, it should retain its original spelling. If it is an adjective, then the ending should be changed to match the gender of the genus, which is indeed neutral (stoma being a Greek word of neuter gender). Despite a couple of hours searching, I cannot find out whether seminationis is a noun or an adjective. Sad Anyone got a very big Latin dictionary? Smile

seminationis is a noun. It is a genitive of seminatio--- it means "of reproduction" (or something like that) Smile . I'm curious about the meaning of Platystoma... because I didn?t find in dictionary. awkward
Today I found lots of flies, some are new... Wink and i found very probably this fly -> Platystoma cf. seminationis above Olea europaea's trunk.

I think "Platy" refers to broad or flat and "stoma" to mouth, so Platystoma means "broad-mouth".

The new "face" is the posterior end of a Tipula larva. Having taken the photos, I couldn't resist cropping one for a new avatar - this is exactly what it was like - no Photoshop alterations! Cool

Andrius,

Welcome to the World of Platystomatidae, where there are many taxonomic problems. Hennig, W. 1945. Platystomidae. Die fliegen der Palaearktischen Region: 48: 1 - 56. is your best bet, although not ideal in some respects.

Platystoma seminationis (Fabricius, 1775) is correct.

I'm intrigued - what do have? Are there many specimens and is there a need for a revised key to the European species? I have been focusing on the tropical fauna, because there is so much more work required there.
