Hi Graeme, I see you still have the death penalty for biting legs. Could you please check whether the basicosta are bare or with small bristles. ? It is the small scale at the base of the wing (anterior margin, so at the base of the costa). Theo |

Hi Theo. Yes will do. I should have notes on basicosta from a previous post. |

My interpretation is that the basicosta is bare. Graeme Cocks attached the following image:  [70.89Kb] |

I agree. So now for the ocelli: are there functional ocelli present ? And does or does not the hind tibia have preae-apical spurs ? Theo |

Hard to say, but my guess would be the ocelli are none functional. Graeme Cocks attached the following image:  [110.95Kb] |

There is an apical spur, but does preapical mean there is another one? Graeme Cocks attached the following image:  [115.77Kb] |

My mistake. That is the mid leg I enlarged in the previous picture. This is the hind leg. Graeme Cocks attached the following image:  [86.63Kb] |

No the ocelli are present and the spurs are OK, there is no difference between " apical" and " prae-apical", for some reasons we use the last. So this is in Chrysopsinae, not in Tabanninae ! Surprise ! Something like Pseudotabanus. Need to work on that. Theo |

I have nothing similar in my collection, so we need to work our way through Mackerras', key. Could we get a frontal picture, showing the calli ? Eye are bare ? Theo |

And a lateral of the head would be nice, showing the palpus. My predictions; * Subcosta hairy below * you are between Townsville and Rockhampton In which case it is the female of Pseudotabanus distincta. Theo |

I am not familiar with the palps of diptera, but these look quite small, well compared with lepidoptera anyway. |

Thanks, Graeme. Then I will stop torturing you. What about your locality ? Is it indeed between Townsville and Rockhampton ? Theo |
