| Memo: | Hemming (1967) stated:- Walker used the name Erchia as a new generic name twice in the same volume, namely the present name Erchia (: 357) and Erchia (: 321), this latter being applied to a genus of Dioptid moths. For names such as these published in the same work and on the same date, the relative precedence to be accorded depends on the choice made by the First Reviser. In this case the First Reviser was Kirby when in 1892 (Syn. Cat. Lep. Het. 1 : 410) he gave precedence to Dioptid Erchia (: 321) over the present Erchia, introducing for the latter the replacement name Pseuderchia. In introducing the present name, Walker erroneously supposed that its type-species, Erchia extranea, was a Geometrid moth, whereas in fact it is a Riodinid butterfly. In consequence of the way in which these names were published by Walker, they have been completely overlooked in the literature of the butterflies. The true nature of these taxa only came to light recently in the course of work in the British Museum (Natural History), as I was informed by Mr. N. D. Riley when he kindly drew my attention to these hitherto unknown names. If the discovery of these ancient names had led to the upsetting of names in current use, there would have been a very strong case for asking the Commission to reject them as nomina oblita. Fortunately, however, such action is not required in the present case : - (i) The generic name Erchia Walker, as applied to the Riodinid butterfly, is (as shown above) invalid under the Law of Homonymy. (ii) The nominal species Erchia extranea Walker (the type-species of Erchia) is subjectively treated as representing the same taxon as that represented by the older-established nominal species Limnas barca Hewitson, [1853 (Ill. exot. Butts 1 : [120], pl. 60], fig. 12), and in consequence the specific name extranea Walker falls as a junior subjective synonym of barca Hewitson. (iii) The generic name Pseuderchia Kirby, 1892, typified as indicated above, is a junior subjective synonym of Melanis Hübner, [1819] a genus commonly but incorrectly known by the name Lymnas Blanchard. Watson, Fletcher & Nye (1980) stated:- Erchia was established as a subgenus of Dioptis Hübner, 1818. The higher classification used here follows Lamas (2008). |
