Thread subject: Diptera.info :: Lauxaniidae chaetotaxy
Posted by viktor j nilsson on 12-11-2009 12:32
I have a small question regarding the thoracic chaetotaxy of Lauxanids. In the manual of palaearctic diptera, it is stated that lauxanids have 0-1 intraalar bristles. But I wonder if it shouldn´t say 0-2 instead? Shouldn´t the pair of bristles behind the one denoted "ia" In the attached picture from Shatalkin (2000) also be called intra-alar bristles?
The reason that I came to think of this that was looking at a Minettia specimen which only has the posterior pair of bristles (maybe many Minettia looks like this?), and the key asked whether intra-alars are present (which they obviously should be in Minettia)?
are both pairs of bristles intra-alars?
