  abstract = {{B}ackground and aims-{G}abon is a major centre of biodiversity. {W}e describe a new species from the tropical plant family {A}nnonaceae: {U}variopsis niangadoumae sp. nov., known from a single population in the {M}onts de {C}ristal {N}ational {P}ark. {M}aterial and methods-{F}ield work was conducted to collect plant specimens and observe floral visitors. {P}ollen samples were collected and prepared for microscopic analysis. {T}he phylogenetic tree of {U}variopsis was reconstructed using a maximum likelihood method and based on hundreds of nuclear markers. {P}ollination biology was studied using a {DIY} camera trap ({PICT}) placed near a female flower to record floral visitors and their behaviour for one full day. {S}everal flower visitors were collected and identified using {DNA} barcoding. {K}ey results-{U}variopsis niangadoumae is a tree reaching five metres tall, characterized by strong-scented leaves, few-flowered cauliflorous foul-smelling flowers, and large pollen grains shed in tetrads. {T}he species is endemic to a small area within the {M}onts de {C}ristal {N}ational {P}ark. {P}hylogenetic analysis places {U}. niangadoumae within the "large-leaved clade" species complex with now five taxa. {P}ollination is diurnal, and the primary pollinator is a rove beetle ({S}taphylinidae), which uses the female flowers as a mating site, with males fighting for control of the flower. {T}he rove beetles might be attracted by a chemical cue, the foul scent of the flowers, and visual cues, with the inner part of the petals resembling mushrooms. {C}onclusion-{T}hese results emphasize once again the importance of the {M}onts de {C}ristal {N}ational {P}ark for biodiversity and highlight conservation concerns for the newly described species. {T}he new species is monitored regularly, especially for fruiting individuals, to support ex situ propagation. {T}he {K}ingu & eacute;l & eacute; {A}val project maintains a conservation nursery with 56 species, including 20 individuals of this new species.},
