Erechthias

Erechthias is a genus of the fungus moth family, Tineidae. Therein, it belongs to the subfamily Erechthiinae, of which it is the type genus. The exact circumscription of this genus is still disputed, but it may encompass more than 150 species.

==Systematics and taxonomy== Here, the genus is treated in the wide circumscription (sensu lato) adopted by many authors today, and represents the presumed core group of the Erechthiinae. Delimited thus, Erechthias includes several other genera, some of which have occasionally been treated as independent even by fairly recent authors. They are still rather similar and contain moths that are (at least overwhelmingly) very closely related. Still, they differ in details such as the wing venation – with Erechthias sensu stricto having all veins separate (as opposed to e.g. the Decadarchis group, which has hindwing veins 5 and 6 stalked) – or the clasper's harpe being nude in Erechthias s.str. but bearing a cluster of setae on the costa. However, the female genitals look almost alike in all of them.
