Found in a hilly area in Vienna. Edited by Carnifex on 08-09-2019 09:03 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

I wonder about the definition of 'abdominal discal bristles' - how far anteriorly can the marginal bristles move, that they are not considered as discal? Because on the tergite 2 of my fly there are two bristles in the black spot, that aren't discals, or? Mid tibia with small pd-bristle? First tarsal segment of fore leg Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

For instance, the usage of ‘ apical, subapical lateral, subbasal’. and even ‘ second lateral’. for bristles on the scutellar margin is actually undefined. If there are only three pairs, is the middle one subbasal, lateral, subapical .... ??? It would be better to just give the number and, if necessary, describe the position of its base. Now, returning to your question: Yes, but this problem only occurs in Cylindromyia (in Tachinidae). Moreover, there is no such thing as far as I know as a discal tergal bristle without a marginal tergal birstles. Therefore -1) it is still useful to use ‘ discal’ in Tachinidae context -2) it is clear that in Cylindromyia we are dealing with advanced marginals. By the way, the degree of advanceness is species specific ! Theo
