I'd say Eliozeta. Hairs on the abdomen are recumbent, no erect as it happens with Clytiomyia. Wait for Theo, Chris, Jaako, neprisi....  |

How many sternopleurals/katepisternals does it have? 269. 3 st (but the lower sometimes hardly differentiated from the hairs). Males: hairs of the tergites in their centre - as on the sides - prone; if a few hairs are raised, then these remain considerably shorter than 0.5 of the marginal bristles; tergite 6 bare or with hairs on its dorsal area. Females: parafrontalia outside the frontal bristles with hairs............Eliozeta (page 66) - 2 st. Males: hairs on the middle of the tergites raised, the longest hairs at least as long as 0.5 the marginal bristles; tergite 6 always with hairs on its dorsal area. Females: parafrontalia outside the frontal bristles bare...............Clytiomya [continua Panz.]

I hope you are right, I've never seen Eliozeta. |

yes. I tried to count the katapisternal setae... but it is not possible here.  |

I see only two katepisternals, despite the legs being in a position that makes it difficult to see very well. I think that there isn't a lower bristle. |

The third antennal segment is elongated and the arista strongly crassate, therefore, it is pellucens, and thus Eliozeta. This is always the first thing to check, when in doubt ! Theo |
