Review of the Afrotropical genus Dracontogena Diakonoff, 1970 (Lepidoptera, Tortricidae) with descriptions of eight new species Author Aarvik, Leif Author Karisch, Timm Author Marthinsen, Gunnhild text Zootaxa 2012 2012-09-11 3478 345 372 journal article 10.11646/zootaxa.3478.1.32 f3e4ca1e-a40b-465a-a900-7a898e472cde 1175-5326 282268 FC92E481-4FF7-4DD8-B7C9-9F192F373D2E Dracontogena metamorphica species group Male hindwing without modifications, valva lacking internal circular scale patch, male abdomen without coremata. The spatulate scales at the hindwing anal corner have a serrate distal edge. The species are variable, and in general, dissection of the genitalia is necessary for accurate identification. Dracontogena metamorphica ( Meyrick, 1928 ) ( Figs. 46 , 62, 63 ) Eucosma metamorphica Meyrick, 1928: 439 ; Clarke 1958: 375 , pl. 186, figs. 1, 1a. Dracontogena metamorphica Karisch 2005: 462 , text figs. 13, 15, pl. 1, fig. 8. Material examined. Lectotype of Eucosma metamorphica , 3, Sao Tomé , February , T.A. Barns , genitalia slide BMNH 9396 ( BMNH ); 1Ƥ, same data as lectotype, genitalia slide 30576 ( BMNH ); 1Ƥ , same data as lectotype, genitalia slide L. Aarvik 2011.025 ( USNM ). Diagnosis. Wingspan 20.0–25.0 mm. Externally, D . metamorphica resembles the bicoloured form of D. kingstoni n. sp. (see below). The male genitalia ( Fig. 46 ) are distinct by the deeply excavate ventral edge of valva. The female genitalia ( Fig. 62, 63 ) have sternite 7 deeply excavate with two membranous bands anterior of the excavation; segment 7 with conspicuous scale sockets anterolaterally; the sterigma large, becoming wider posteriorly; and the paired oval sclerites posterior of the sterigma small, separate. Distribution. Known only from Sao Tomé , an island in the Gulf of Guinea , West Africa.
