En hommage à Jeannine Morati et en remerciement à Michaël Huet qui m'ont tous deux gentiment accueilli en toute simplicité il y a quelques années dans leur village de Haute-Savoie, je me suis appliqué à rassembler une petite collection de ces magnifiques insectes très colorés et j'ai mis au point, en m'inspirant largement du travail de ces deux auteurs, une clé très simplifiée mais extrêmement efficace...

Hi, Benny !
No it is not a valid species. It is a synonym of P. dimidiata :
Pachyteria scheepmakeri Ritsema, 1881 = Pachyteria dimidiata Westwood, 1848. |

| Do you see any other differences between nocki and ruficollis besides this small zmount of coloring at the base and apex of the pronotum? Honestly, I am very skeptical as to whether nocki is a good species. |

According to Bentanachs (2015), P. nocki differs from P. ruficollis, besides the color of the pronotum, by a sparser pronotal punctation and by more feebly punctured elytra.
I have also doubted about the value of this new species for me, all these differences are subjective rather than scientifically defined. I still leave the benefit of the doubt to the inventor of the new species because my P. nocki has a pretty deep blue color while my 4 P. ruficollis are greenish. I need more material to be able to decide ! |
