Systematics, revisionary taxonomy, and biodiversity of Afrotropical Lithocolletinae (Lepidoptera: Gracillariidae) Prins, Jurate De Kawahara, Akito Y. Zootaxa 2012 2012-12-20 3594 1 1 283 8VM4V De Prins 2012 [207,316,836,862] Insecta Gracillariidae Phyllonorycter Animalia Lepidoptera 97 98 Arthropoda species hibiscola  The only species belonging to this group,  Phyllonorycter hibiscolaDe Prins, n. sp.can readily be distinguished from many Afrotropical  Phyllonorycterby the deep golden brownish ground colour and golden brownish shine of forewing that resembles  P. adderis,  P. gato, P. lemarchandi,  P. umukarusand the European species  P. schreberellaand  P. tristrigellathat feed on  Ulmussp.The above-mentioned species also have a different male and female genital morphology and fall into different informal species groups. Therefore, only dissections provide means for the designation into species groups and species identification. The discovery of a male could resolve the taxonomic position of  P. hibiscola. At the moment, we place  P. hibiscolainto its own species group. Female genitalia are characteristic for having a long, narrow, fold-like sclerotization of cuticle, ostium bursae situated at middle of segment VII, a heavy sclerotized ring encircling the anterior margin of segment VII, short ductus bursae, corpus bursae elongate, without signum. The  hibiscolaspecies utilizes Malvaceaeas its host plant.
