Type species of genera in Aphididae (Hemiptera Sternorrhyncha) with two new generic synonymies

Abstract

The aphidologist community attending the Seventh International Symposium on Aphids in Fremantle (Western Australia, 2005) entrusted to us the preparation of a Part of the List of Available Names in Zoology devoted to the aphid genus-group taxa names, and this to be presented at the subsequent aphid symposium. During the course of our work (Nieto Nafría et al. 2009), we checked each genus to make sure its type species designation conformed to the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999) ―henceforth The Code and The Commission―, and that these designations were correctly represented in the literature, especially the two most recent taxonomic catalogues (Eastop & Hille Ris Lambers 1976; Remaudière & Remaudière 1997). Previous authors have used most of the procedures of type fixation enumerated in The Code, The Commission itself has used its Plenary Powers to fix six type species, and 11 genus-group names remain without types (Table 1). In the recent aphid taxonomic catalogues (Eastop & Hille Ris Lambers op. cit.; Remaudière & Remaudière op. cit.), we found three errors caused by mistakes propagated in the literature and two errors caused by incorrect application of Article 11 of The Code. We have also found that in the case of 11 names, the criteria of Article 70.3 of The Code were not met, and regardless, earlier editions of The Code did not allow type designations of that kind (see the last paragraph of the example in Article 70.3). This article corrects the five errors and conforms the 11 aphid type species designations to the nomenclatural standards of The Code.
