Dear all, Is it possible to separate Culex from Aedes based in differences in R2 and R2+3 length? I've read that in Culex the R2 is larger than the size of R2+3 (A and B in figure), and that in Aedes is the opposite (C and D in figure). My specimens are from southern Brazil, and as a herpetologist I'm just trying to have a first identification of genera... within Culicinae, my main interest is to diagnose Culex. Images are not at scale, ignore the values. Thanks vmcaldart attached the following image: [188.67Kb] Edited by vmcaldart on 22-08-2014 02:45 |

The only mention of the R2+3 fork in keys I checked was to distinguish Uranotaenia from most other Culicinae. In North America Aedes has a pointed abdomen and Culex a blunt-tipped abdomen, at least if live specimens are viewed laterally. |

But in Uranotaenia the A1 vein ends before the union of CuA1 and CuA2... thats not the case of the specimens in the picture or other Culicinae. |

R2+3 begins where R4+5 forks off. Before that point the vein is simply Rs. |
