Laysan hedyleptan moth

 

 

Taxonomy & Nomenclature

Synonym/s: Hedylepta laysanensis Meyrick, 1914

 

Conservation Status

Last record: 1911 (source)

IUCN RedList status: Data Deficient

 

Haines (2004) lists the author of the species as Meyrick, 1914, but (Beccaloni et al. 2003) gives the author as Swezey, 1914. This conflict needs to be resolved, and can be if the paper ("Swezey. 1914,Proc.Haw.ent.Soc.3:19") cited as the original description of the paper by (Beccaloni et al. 2003) is examined. Haines (2004) states that "information since the last assessment in 1996 suggests that this species is still extant in the Hawaiian Islands", however no explanation of the nature of this "information" is given. Preston (1998) had this to say about its status:
 
[i]"Recorded only from Laysan, this species is possibly extinct.  It may have always been rare and therefore not of major importance for our purposes.  It is important because of it’s rarity and because little is known about it.  There are over  23 species recorded from the Hawaii (sic) Islands.  Many more remain undescribed either because they are unique or because expertise is unavailable.  There is only one researcher semi-active in Hawaiian crambids and he has not been back to Hawaii for several years.   It should be noted that not (sic) last date of collection is given in Asquith’s 1994 unpublished report and Butler, 1963 makes no refference to it."[/i]
