I think this is a female Sarcophagidae. Could it be Sarcophaga sp.? Contrarily to similar flies I see in this place, the tip of the abdomen is not redish. Thanks, Joaquim Gaspar |

Although some genera in the tribe Sarcophagini have orange genitalia not all do - it's just one of many features that key out the different genera. Also, I think the orange genitalia only apply to males - females are usually (always?) black  Anyway, looks big - like a Sarcophaga sp. to me, but I'd need the specimen to be sure

And it's a male.... Sarcophaga ss. does not have orange genitalia, these are found in other 'genera' like Helicophagella. Theo |

Theo Thank you for the help, it appears I have landed in a difficult subject... How can one distinguish between a male and a female Sarcophagid? Edited by Alvesgaspar on 28-10-2007 16:27 |

IN most calyptrate flies (Sarcophagidae included), the female has a larger gap between the eyes with 2 additional pairs of proclinate setae (thus lacking in the male). Moreover, if the pulvilli are enlarged (as in the first pic), you have a male in front of you (however, vice versa is NOT true). There are exceptions. Theo |

Just for those who are reading and can be lost with the terms. Calyptrate flies - those flies that have calypter - they belong to the Calyptratae  . Calypter is located below the wings and usually with 2 pairs. The last tarsomere (=distitarsus) usually bears 2 claws (i never saw a fly with 3 claws.. garras in Portuguese) . Sometimes, the last tarsomere can have two pulvilli with an empodium in the middle. The pulvilli above have red colour. It is very clear in first photo at your left (1st and 2nd left legs). The empodium IS NOT visible in your photo. (it is located between the pulvilli). We would need more magnification to see that.  NOTE: Tarsus [the segment more apical of the leg - more near the ground ] has 5 tarsomeres. The first tarsomere (more basal one - i.e. more near tibia than the ground) is called metatarsus=basitarsus; the last is called distitarsus (from distal).See here for: proclinate setae For setae see Overviews section for more information. Specially this one: http://www.dipter...ad_id=8790 Edited by jorgemotalmeida on 28-10-2007 17:49 |

Thak you for the entomologic anatomy lesson. I'll need a couple of months from now to absorb all these new terms |
