Name

• Leiuromys occasius (Thomas, 1921)

Holotype: BMNH 21.2.15.6, juvenile ♀, skin and skull.

Type locality: “Gualea, Ecuador, west of Pichincha. Alt. 4000' [ft]”, probably in error (Tate (1935: 428), Emmons (2005: 282), Emmons & Patton (2015: 913)), almost certainly somewhere in the lowlands of eastern Ecuador (Emmons & Fabre (2018: 25).
