Hi, 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)? So: are both pairs of bristles intra-alars? Best wishes, Viktor viktor j nilsson attached the following image:  [112.73Kb] |

Oh, I think I made the very same mistake as in this thread: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=7225 ...in that I tried to squeeze a Pseudolyciella specimen through the Minettia keys! So then... the bristle behind the intra-alar on the picture above shouldn´t be interpreted as an intra-alar? Then what is it!? cheeers, VIktor |
