c'etait pourtant assez evident (L'Entomologiste...)

dans ce cas il est dommage que les reponses n'aient pas ete envoyees a
TAXACOM! D'autant plus que si vous envoyez ce second message, c'est que la
question semble necessiter un debat.

cela est difficile a croire (si je comprends bien ce que vous voulez dire
par <<validly described species>>)! D'ailleurs, comment peut-on affirmer
que de tels noms sont valides si les conditions de l'Art. 13 a (i) ne sont
pas remplies? Il nous faudrait des EXEMPLES precis!

>My confusion was because the description could be interpreted to mean
>(paraphrased) "An Achrestus from Martinique that has the color pattern of F.

ceci est un enonce de ce que ces deux bestioles ont en commun, non un
caractere differentiel, en contradiction avec les exigences de l'Art. 13 a
(i) ("a description or definition that states in words characters that are
purported to differentiate the taxon").

je suppose que la figure peut etre utilisee afin d'aider a
l'interpretation, mais elle n'a rien a voir avec le fait que le texte est
acceptable comme diagnose ou non.

En Botanique au moins, un nom non validement publie n'a aucun statut
nomenclatural. Avant de proposer d'inserer un nom dans la liste des noms
rejetes il est donc necessaire de s'assurer que ce nom est valide,
c'est-a-dire qu'il... existe!
