This Limnophora give me a headache.  Unfortunately, I have only this lateral picture, but fly was collected. Running Gregor et al. key : 2 or setae + 4 ps dc -> couplet 5 5a. Setulae on basal part of R4+5 reaching almost to half distance between radial node and anterior crossvein. -> couplet 6 5b. Setulae on basal part of R4+5 confined to radial node. -> couplet 7 I have already some doubts from here, because I find 3 setulae after radial node, but confined in the basal fifth to distance betwween radial node and r-m crossvein. If I take couplet 6, I have choice between L. olympiae and L. setinerva. If I take couplet 7, with only 1 post. seta on mid tibia, I have choice between L. riparia and L. exuta (ruling out out L. caesia and L. pulchripes). Running d'Assis Fonseca key, it is worse, I can't tell whether profrons is so angular or not, it seems to be intermediate between fig. 10m and 10n ! So, your advices are welcome. Locality : Le Havre (France) Date May, 6 2007 Size 6-7 mm. Edited by Stephane Lebrun on 06-08-2007 14:10 Stephane. |
