Plume moths (Lepidoptera, Pterophoridae) of a recently discovered lepidopteran diversity hotspot in the Mount Cameroon area, with descriptions of four new species

Mount Cameroon is a major Afrotropical biodiversity hotspot, yet its moth fauna remains poorly documented. This study records 34 plume‑moth (Pterophoridae) species, including four newly described taxa—expanding national totals from 19 to 48 species. Twenty‑five species are newly reported for Cameroon, and diagnostic images for Titanoptilus melanodonta are published for the first time. These findings significantly broaden knowledge of plume‑moth diversity and extend species distributions across the region. They also reinforce the conservation value of Mount Cameroon, where habitat degradation and climate pressures threaten unique ecosystems and highlight the need for enhanced biodiversity protection.
