Description

'' E. sigma'', the type and possibly only species, is a mid-sized noctuine with a stout body and almost uniformly dark brown wings. There is some reddish or buffy suffusion on the leading edge of the forewings and a thin cream-colored margin to the hindwings. The forewing markings are indistinct except for a roundish and a
kidney The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal arteries; blo ...
-shaped stigma, which are blacker than the rest of the wing and surrounded by a thin band of reddish brown. Altogether, the moths do not resemble their closest relatives much (arguing for retention of the genus as monotypic, at least for the time being), rather appearing somewhat like certain species of '' Graphiphora'' and '' Spaelotis''. The male genitalia resemble those of '' Anagnorisma'', most conspicuously differing in the vesica penis. In ''Eugraphe'', this has a number of sclerotized (hardened) ribs in the inner curve and a shorter and more delicate subbasal cornutus; the latter also serves to differentiate ''Eugraphe'' from '' Coenophila''. The lack of subterminal cornuti is a tell-tale mark of the present genus versus '' Eugnorisma''. Most characteristic in the female genitalia is the ostium bursae, which has posterolateral extensions shaped like a

's ears. However, similar extensions is also present in some ''Anagnorisma'', whose female genital structure is generally comparable (but never entirely alike).
