5.7mm, damp grassland, western England, July 2010. Preac Abdomen dark Scutellum dark F black Np bare T3 with 1 pd in apical third Crossveins infuscated Prealar = posterior np However, no lateral marginal scutellar hairs below level of strong bristles. Would appreciate advice at this point if there are any more likely identifications. Liancalus attached the following image:  [72.81Kb] Edited by Liancalus on 23-12-2013 00:08 |

Please, what is that cercal plate : the pictures are from a female ! Thr pra is too long for P. cincta. P. laeta maybe (broad palpi ?). Stephane. |

OK, I see where I went wrong in Gregor, T2+3 are a very dark brown but you can only see this with the lighting from certain angles. Following that takes me to laeta/pratensis. What do you think of the vitta colouration please Stephane? I think it's closer to grey than velvety black, the dusting looks uneven, perhaps some has worn away which makes it look darker than it might otherwise have been The palpi look broad (5 units) though not quite as broad as the flagellomere (7 units) which Fonseca suggests might be ok, Gregor less so, though I wouldn't say this is much narrower either.

I stick on P. laeta. The thoracic patter matches too. The frontal vitta is not so contrasting, but it is often hard to evaluate.
Stephane. |

Thanks Stephane. That seems a conclusion, at least as far as I can say without collecting more specimens or comparing it to reference material. |

Hello Phaonia laeta Looking through my info… Tibia 1 without a p seta yes Scutellum bare on lateral margins- you have checked yes Np bare- apart from 2 strong setae- looks ok from photo Abdomen without a brown dusted spot at the hind corner of tergites 3 and 4 – side view looks ok from photo A good find Dr Elisabeth A.

Hello Elisabeth T1 0 p seta Scutellum bare on lateral margins below level of strong bristles Np bare except for 2 bristles Marginal area of tergites uniform Although I gave habitat as damp grassland and I do not remember the exact circumstances of collection, I suspect it was associated with a dead standing oak which also produced some good local beetles that day (Sepedophilus bipunctatus and Vanonus brevicornis). |
