La seule espèce de Nyctopais présentant des tibias jaune est N. jordani mais ici ce n'est pas ça !
Par contre regardez du côté peut être de N mysticus ??
Ce sont des espèces très variables dans la coloration . Donc à voir de près |

The correct name is Poimenesperus Thomson, 1857.
Gemminger & Harlod (1873) proposed the unjustified emendation Poemenesperus.
Nyctesperus Breuning, 1934 is a subgenus of Poimenesperus including only Poimenesperus niveicollis Aurivillius, 1903
Both works are in our library and the correct spelling in BioLib here.  |

What is the correct spelling : Poimenesperus or Poemenesperus ? or are they two different genera (as suggested in Titan).
What looks strange on Titan is that Poimenesperus is set as monospecific including a subgenus Nyctesperus (a nonsense) |

Me too, if possible.
The names of two last photos seem to contain spaces. |

Thanks for contributions all!
For key characters see Breuning 1934 (Nov.Ent.I, page 8-10). Especially the drawings on p. 8 of the shapes of the pro- and mesosternal processes in relation to pro- and mesocoxae are diagnostic.
I attach two photos showing details of these structures indicating the species must belong to Nyctopais.
But none of the 4 described species fits with "the yellow-legged thing". |

To me, Poimenesperus has a different shape of pronotum and different ratio of the widths of elytra shoulders and pronotum. Nyctopais is cylindric. I don't know the key characters, but have representatives of both genera. Nyctesperus is more difficult.
I wrote Nyctopais(?) just because the photo strongly resembles all three Nyctopais species known to me. Though I have not earlier seen yellow tibia. |

a technic question : how do you distinct Poimenesperus from Nyctopais ? |
