[Taxacom] Cross-rank homonyms (in zoology)

[Francisco Welter-Schultes]

Dear Tony,
as you suspected, cross-rank homonymy is allowed.

The same name can occur at different ranks in the hierarchy and can have 
a different meaning there. Some examples:

Examples:
Reticulata is used as an order in Foraminifera, and as a clade in 
Ephemeroptera.

Acanthocephala is a well-known group of gnathiferan worms.
Acanthocephala Laporte 1832 is a genus of American bugs (Hemiptera).

Trochoidea is a superfamily of large sea snails (Gastropoda), a name 
derived from the generic name Trochus. The same name Trochoidea Brown 
1827 is a genus of European terrestrial snails.

Chitonoidea is a superfamily of chitons (Polyplacophora), a name derived 
from Chiton. Chitonoidea Svihla 1983 is a genus of Iranian beetles 
(Coleoptera).

Delphinoidea is a superfamily of toothed whales (Mammalia), a name 
derived from Delphinus. Delphinoidea Brown 1827 is a genus of tiny 
marine snails (Gastropoda).

Likewise generic names are Acrania Burr 1915 (Dermaptera), Amphibia 
Berthold 1827 (Pulmonata), Aptera Saussure 1864 (Orthoptera), Ciliata 
Couch 1832 (Actinopterygii), Homoptera Boisduval 1852 (Lepidoptera), 
Mecoptera Guenée 1837 (Lepidoptera), Radiolaria Provancher 1886 
(Hymenoptera), Trichoptera Meigen 1803 (Diptera).

If this helps
Francisco
