They should be a pair of Neoplocaederus spinicornis (Fabricius, 1781) |

Actually, I am not perfectly sure... I have seen that some insect sellers in the Web offer Neoplocaederus fucatus (Thomson, 1858) from Togo. The original description of this species is in the library here at the p. 150 (9th of the paper), but I could not notice any difference with N. spinicornis (even mentioned in the description). It is interesting to observe that all entomologists until Gahan (1890) referred to N. spinicornis a drawing by Olivier (1795)... which actually represented Prosphilus serricornis (Dalman, 1817)! Hence, was actually N. fucatus is, it is for me mysterious... |

Yes, Francesco, I agree with you. Comparing these specimen with the "spinicornis" from Cameroon I have in my collection, I can not notice any difference. They seem to be perfectly identical.What a frustrating fact. Does there actually exist among the African Cerambycidae one single minute genus which does not need a revision...? |

Bonjour.... Je relance le débat avec ce spécimen de Sao Tomé (35 mm). Neoplocaederus fucatus ou spinicornis ? ou alors une n. ssp. car tous de grandes tailles avec un rapport Longueur/Largeur élytres bien différent des deux espèces précitées... J'attends vos avis... |

Bonjour Norbert, je voie une différence au niveau des antennes. Pour les bêtes de Pierre, les antennes sont (spatulées et épineuses) du troisième aux neuvièmes articles et sur ta bête les articles sont épineux du trois au septième.

A mon avis il s'agit en tous cas de Neoplocaederus fucatus (Thomson, 1858). Il diffère de spinicornis pour la pubescence plus abondante et l'apex du pronotum couverte des rides déprimées (parfois avec un sillon longitudinal). Les antennes sont dentés jusqu'au 10e article dans les deux. |

Bien; le sujet m'intéresse tout de même... Il y a beaucoup de confusion dans les Néoplocaederus africains notamment de couleur métallique. Comment y voir clair? |
