Another one with inflated femur... CHongwe, Lusaka, Zambia. Amongst grasses/non-native Mexican daisies in heavy shade. 07 March 2013 Size: quite large, probably about 22mm? Similar to other species suggested to be Hoplistomerus (and in same area), but seemed darker, hairier and more thickset upon examination of photographs. [EDIT: changed title to reflect identified genus and possible species. Was formerly "Black Asilidae, Africa - Hoplistemerus sp?"] Will van Niekerk attached the following image:  [190.49Kb] Edited by Will van Niekerk on 25-04-2013 16:08 |

Hi Will, Should be Laxenecera cf. albicincta. This is a widespread, variable species. Its also sexually dimorphic, this is the male, whereas the female has brown hairs and is much broader. regards, Steve |

Hi, Steve! Thank you for that. With the overall appearance being broadly similar, and my not noticing that there was a difference until looking at the photos later, is the similar individual with a brown frill to its thorax (http://www.dipter...d_id=54135) likely to be the female of the species? Thanks again, Will. |

Maybe, there are several other species of Laxenecera, but albicincta is the really common one. You'd need a specimen to be 100% sure. Torsten Dikow (who is a leading authority) has photos of a pair in cop. on his flickr site - http://www.flickr...hotostream Hope that helps, Steve |

Looking at the pictured copula, the differences between the male below and the female above correspond to the differences between to two 'varieties' I photographed, so for now I'll add a cautionary note to the browner specimen and file her in with this one... Thanks again. |
