Silvascincus tryoni, also known commonly as the Border Ranges blue-spectacled skink and the forest skink, is a species of lizard in the subfamily Sphenomorphinae of the family Scincidae. The species is endemic to the McPherson Range bordering New South Wales and Queensland, Australia.
Etymology The specific name, tryoni, is in honor of English scientist Henry Tryon (1856–1943).Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). The Eponym Dictionary of Reptiles. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (Eulamprus tryoni, p. 268).
Description Silvascincus tryoni can grow to in snout-to-vent length (SVL). It has well-defined, dark transverse dorsal markings on a light to mid-brown background.
Reproduction Silvascincus tryoni is viviparous. A female measuring SVL and total length (tail included) gave birth to five young measuring SVL.
Habitat and behavior Silvascincus tryoni occurs in highland closed subtropical rainforest at elevations of above sea level. Specimens have been found on logs and rocks, under decayed logs, and sunning at the base of a hollow giant stinging tree Dendrocnide excelsa. When disturbed, they seek refuge under rocks and logs.
Conservation Silvascincus tryoni might be at least locally common. Its range is small but coincides, perhaps entirely, with protected areas, including Lamington and Border Ranges National Parks. It is unlikely to be facing any major threats.
