Scythris notorrhoa Meyrick, 1921. Exotic Microlepidoptera, vol. 2 (part 14): 441.

Material examined.

Lectotype. Brazil • ♂; Amazonas, Manaos; 11.19.; Parish leg.; [genitalia slide] JFGC No. 8065; NHMUK ID 010922363; NHMUK slide ID 010316671; coll. NHMUK.

Paralectotype. Brazil • 17 exx.; same data as for lectotype; coll. NHMUK .

Diagnosis.

Scythris dividua , S. medullata , and S. notorrhoa are similar externally. Reliable determination can be achieved by genitalia examination (DNA barcodes not available for all these three taxa yet). Uncus pentagonal, heavily sclerotised in Scythris dividua ; rectangular, small, less sclerotised in Scythris medullata ; oval and heavily sclerotised in Scythris notorrhoa . Valvae narrow basally, inner margin without sclerotisations in Scythris dividua ; broad basally, inner margin with minute sclerotisation in Scythris medullata ; asymmetrical, inner margin with large sclerotisations in Scythris notorrhoa . Segment VIII distinct in each three species, see illustrations.

Description.

The original description is quoted: "♂ ♀. 10-12 mm. Head bronzy-fuscous, sides ochreous-whitish, or in ♂ wholly suffused ochreous-whitish. Palpi fuscous more or less suffused ochreous-whitish. Thorax dark bronzy-fuscous, an ochreous-whitish, on inner side of patagia, in ♂ more or less suffused ochreous-whitish. Abdomen dark grey, beneath suffused ochreous-whitish. Forewings ♂ fuscous, ♀ dark bronzy-fuscous: a broad ochreous-whitish median stripe from base to termen, sometimes with slight apical projection above, dorsal area below this stripe in ♂ wholly suffused ochreous-whitish, plical stigma sometimes marked on lower margin of stripe: cilia grey, in ♂ paler and more or less suffused ochreous-whitish on termen. Hindwings 0.6, 4 and 5 separate; dark grey; cilia grey."

Male genitalia. Uncus heavily sclerotised, oval, slightly pointed on apex, surface granulate. Tegumen hood-shaped. Valvae asymmetrical, margins reinforced at basal 1/3: left valva longer, rather narrow, subapically with elongated and heavily sclerotised ventral extension, apex with long setae; right valva beyond middle with two large and complex heavily sclerotised extensions, apex with long setae. Phallus not detected on the lectotype slide (JFGC No. 8065). Sternum VIII large asymmetrical plate; basal portion rectangular; anteriorly with deep quadrangular concavity; posteriorly with two extensions: one short, the other triangularly extended with three stout apical pegs. Tergum VIII pentagonal, posteriorly extended, apically with six stout pegs; anteriorly with deep U-shaped concavity.

Female genitalia. Not dissected.

Distribution.

Brazil.

Remarks.

Originally the type series comprised 80 specimens, but only 20 specimens remain in the Meyrick collection ( Clarke 1965).
