Abstract
Thaumatovalva gen. n. is described and illustrated from the Afrotropical region. As currently defined the genus includes four species: T. deprinsorum sp. n. from the Democratic Republic of Congo; T. albolineana sp. n. (type species) from the Democratic Republic of Congo; T. spinai (Razowski & Trematerra), comb. n., from Ethiopia and Nigeria; and T. limbata (Diakonoff), comb. n., from the Seychelles and Kenya. Thaumatovalva limbata has been reared from the fruit of Cordia somaliensis Baker and C. monoica Roxb. (Boraginaceae) in Kenya. Although structures of the male and female genitalia are extremely similar among three of the four species, male secondary scales on the under surface of the hindwing easily distinguish them.
Highlights
Male secondary sexual structures are abundant and diverse in the tortricid tribe Grapholitini (e.g., Komai 1999, Horak 2006)
While working on the systematics and taxonomy of Afrotropical Grapholitini, we discovered specimens from the Belgian Congo that are superficially similar to Thaumatotibia and/or Cryptophlebia and have two conspicuously different patterns in the male secondary scaling on the underside of the hindwing
It was revealed that males of both have genitalia nearly identical to those of Thaumatotibia spinai Razowski & Trematerra from Ethiopia, and differ from that species in the male secondary scaling
Summary
Male secondary sexual structures are abundant and diverse in the tortricid tribe Grapholitini (e.g., Komai 1999, Horak 2006). It was revealed that males of both have genitalia nearly identical to those of Thaumatotibia spinai Razowski & Trematerra from Ethiopia, and differ from that species in the male secondary scaling.
