Ok, I think this is Drosophila (Hirtodrosophila) confusa. However, trying to follow the key in The Drosophilidae (Diptera) of Fennoscandia (FAUNA ENTOMOLOGICA SCANDINAVICA 39, Bächli et al) I'm unsure about the presence of a 'preapical seta' on the mesotibia. Figures 10 & 11 page 12 of this text indicate that the apical seta is at the lower (away from body) end of the 1st tarsal segment and points posteriorly, whilst the pre-apical seta is at the lower end of the tibia and point anteriorly. No mention is given to setae in roughly the same positions but on the other side of the joint that point in the other direction. Do these get names? Also does 'pre-apical' imply it's not right at the joint? For example, in fig 10 page 12 is there a very large (unlabelled) preapical seta? I will continue these questions in another thread... |
