Thread subject: Diptera.info :: Rhagio atlanticus may be ?

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 !!
