Hello With the location of the wing spots, the color of the face and legs and the translucent but not transparent wings, I don't think it is Rhagio scolopaceus but probably a female Rhagio atlanticus measuring about 14 mm . What do you think ? Thanks for your help, I have others pictures. bernard PS : The picture come from Portugal (Atlantica coast from Torreira) the size is about 14 mm. I don't know haw to add another picture showing the face and legs with coxae in this message. bernard12 attached the following image:  [297.5Kb] Edited by bernard12 on 19-08-2022 11:24 |

Well, Bernard, you clearly did your homework ! Females scolopaceus and atlanticus are very similar, but the shorter antenna here strongly suggests atlanticus. Moreover, scolopaceus is on the Iberian peninsula restricted to the Pyrenees proper and even there it is extremely rare. Atlanticus is pretty common in Portugal. Theo |

Theo, you said in BV news Publicaciones cientifics : "female, scutellum yellow with or without a small grey spot at base". Here it is grey wih a small syellow spot at apex. Is it so variable ? Edited by evdb on 20-08-2022 07:17 Eugene |

Thanks for this close reading. Colouration tends to be very variable in scolopaceus and, apparently, also in atlanticus. About 5% of the scolopaceus females are much more yellow than typical, with yellow pleura etc. I guess also atlanticus is more variable than I destribed. In any case * females atlanticus and scolopaceus are extremely similar, however shape of antenna differs subtle (and no overlap indistribution) * I would never rely on only one colouration feature in Rhagio to separate species (see also discussion in the other paper on funebris with and without vittae on thorax) * find males !! *Theo |
