Fynbosia Englund, Staude & Sihvonen 2026, gen. nov.
Abstract
Fynbosia Englund, Staude & Sihvonen gen. nov. Type species. Fynbosia horingaria Englund, Staude & Sihvonen, sp. nov. Diagnosis. Southern African genus of subfamily Larentiinae (Lepidoptera: Geometridae) present at Cape Floristic Region not attributable or closely related to any described tribus of Larentiinae. Nocturnal small-sized moths with conspicuous male antenna with long ciliated rami, female antenna filiform. Vestigial, defunct proboscis and minuscule two-segmented labial palpi. Adult resting position, small size and elongated fore wing shape resembling those present in genera of Eupitheciini, but the structures of male antenna, proboscis, labial palpi, genitalia, and molecular phylogeny not compatible to any genera of that tribus. Barcode (COI) 658 bp sequence minimum K 2 P distance to closest species (Rheumaptera hastata and Xanthorhoe abrasaria)> 9 %. Closest sister lineage Brabirodes (Brabirodini) based on multigene 4980 bp maximum likelihood phylogenetic estimation. Etymology. Fynbos (> Afrikaans = fine bush) refers to the biome of Cape Floristic Region, where the type taxa reside.
