Picture taken in early February, east China (Zhejiang province). Body length approx. 6mm, observed on bamboo leaves. I think it bears a good resemblance to Leskia sp. in the general body coloration. So could it be in the same subfamily, Tachininae? Or could it even be in the same tribe, Leskinii? Thanks in advannce.

Another shot, lateral view of the same individual.

The resemblance with Leskia is just superficial. Check the converging apical bristles on scutellum, three veins with brisltes all over and the elongated second (apparent: first) segment of arista: clearly a Siphonini. Theo |

I did a quick check. At least (probably more than) 5 species in this tribe have been recorded from Zhejiang, including Actia jocularis, Ceromya flaviseta, Peribaea fissicornis and P. tibialis, Siphona cristata and S. pauciseta. Siphona seems a promising candidate.  |

I think it bears a good (hopefully not superficial this time) resemblance to the Siphona pictures at this link: https://www.dipte...pid=195760 |

Siphona is named for its long proboscis. Most Leskiini also have a longer and more rigid proboscis than your fly. Probably Actia or Ceromya. |

Ah, then I made another mistake in my comparisons. Thank you, John Carr, for pointing it out. I wasn't aware of the proboscis problems. |

Oh, I just realized there's an obvious connnection between Siphona and siphon.

And lower sternopleural bristle is clearly short, so Ceromyia or similar. No Actia is this yellow. Theo |

Thank you, John and Theo, for further narrowing down the possible genera in the Siphonini tribe. |
