Yang, Linlin, Wang, Shuxia & Li, Houhun, 2014, A taxonomic revision of the genus Edosa Walker, 1886 from China (Lepidoptera, Tineidae, Perissomasticinae), Zootaxa 3777 (1), pp. 1-102 : 19

The pyrochra -group

Diagnostic characters. This group is characterized by having a uniformly yellowish-brown to grayish-black forewing; the vinculum ventrocaudal margin without medial process, the uncus with shouldered base touching each other, forming a small membraneous section with tegumen, the twisted uncus lobes with basal half slightly expanded, punctate, distal half heavily sclerotized, hooked, the valva with a large, recurved, hooked basal flange, the short and flat juxta angled caudally, the short and stout aedeagus with basal section paddle-shaped, apex deeply concave at middle, the bulbus ejaculatorius <5.0× length of the aedeagus, not hypertrophied in subdistal section in the male genitalia; the colliculum usually comprising two to three collicular rings, varying in shape among species.

Remarks. Three Chinese species, E. hamata sp. nov., E. robinsoni sp. nov. and E. truncatula sp. nov. are included in this group. Gozmány and Vári (1973) founded this group based on the character that the valva has one or two long and recurved costal appendages arising basally or medially from costa ( Gozmány and Vári 1973: 110, key). They included E. pyrochra ( Gozmány, 1965) , E.phlegethon ( Gozmány, 1968) , E. perinipha ( Gozmány, 1968) , E. lissochlora ( Meyrick, 1921) and E. nigralba ( Gozmány, 1968) from Africa in this group. However, we suggest E. lissochlora and E. nigralba should not be placed in this group, because their ‘costal appendage’ seems not homoplastic with the hooked basal flange, but close to the basal process. Edosa opisgona ( Meyrick, 1911) , E. caerulipennis ( Erschoff, 1874) and E. fibigeri Gaedike, 2012 , should be placed in this group according to published literature.
