Synonyms and other taxonomic changes
Although the name appears feminine, it was treated as masculine by Wood & Bright (1992) and by Bright & Skidmore (1997). Of the three species included by Hopkins, E. (Xyleborus) validus Eichh. has a masculine ending (the other species are E. wallacei and E. streblicola, invariable). Since no gender was specified, Euwallacea is not an originally Latin or Greek word, and there are a number of species of economic importance with names having masculine endings, we are invoking Art 30.2.3. and confirming it to be masculine.(1)
