Historical disappearance and rediscovery

"An extraordinary example of a rediscovered species is Bocourt's Terrific Skink Phoboscincus bocourti (Brocchi, 1876). It was only known from its holotype (supplementary Fig. S1), captured around 1870 in New Caledonia with no further precise locality data, but most likely captured on the largest island called Grande Terre. In 2000, a juvenile was found dead, but not collected, on the beach on an islet off Île des Pins. It was likely prey dropped by a raptor. The first live and immediately correctly identified specimen was found in 2003 by one of us (II) and released. Subsequently one individual was captured and released in 2005, (II), seven other specimens (three captured and released and four more were photographed) in 2012 (by, MH and II), and another individual, illegally collected, in 2018."

(Jowers et al., 2022)

 

Current population status

The IUCN RedList's 2017 assessment of the species reported that the "total number of individuals estimated to be below 100" (Sadlier et al., 2021).

 

Distribution

satellite islet off Île des Pins (=Isle of Pines), New Caledonia

 

"P. bocourti is restricted to one satellite islet of the Isle of Pins (less than 1 km2 area). Although this species is most likely present in several other surrounding islets, it is one of the most geographically restricted endemic skink species in the world."

(Jowers et al., 2022)
