Felicola isidoroi, the Iberian lynx louse, is an extinct species of trichodectid chewing louse.
Extinction
It was known only from a single specimen, a male. In an example of conservation-induced extinction, it likely died out when the last survivors of its host species, the Iberian lynx, were taken into captivity and de-loused. The specimen was slightly larger than males of most of the remaining species within the subgenus Lorisicola. The female has never been seen. The type specimen is in the collection of the Museo Nacional de Ciencias Naturales in Madrid.
