monolagale

Monolagale is a fictional genus created for speculative biology and world-building. It is described as the sole genus of the fictional family Monolagalidae and includes a single confirmed species, Monolagale simplex. The name combines a constructed prefix mono- ('one') and a suffix -lagale used in the fictional taxonomy.

Monolagale simplex is described as a medium-sized, arboreal mammal with a body length of about 40–55 cm and a prehensile tail roughly equal to body length. It has dense, soft fur that ranges from olive-brown to gray, with a pale ventral side; limbs are proportioned for climbing with sharp claws.

In the fictional setting, Monolagale is endemic to the Valara Archipelago, a tropical-fringed chain of islands with a mosaic of primary forests and tall mangroves. It favors mid to upper canopy and riparian zones, often near fruiting trees.

Monolagale simplex is primarily nocturnal and solitary. Its diet is omnivorous, including fruit, leaves, invertebrates, and small vertebrates. It plays a role as seed disperser for several island species and exhibits cache-building behavior.

Individuals are territorial and mark ranges with scent. Reproduction is seasonal, with a single offspring per breeding cycle; gestation is short, with a pouch-nursing period typical of the described marsupial-like reproduction in the fictional ecosystem.

In its fictional world, population status is Least Concern due to island-wide abundance, though habitat loss on individual islands is noted as a potential risk. In literature and field guides within that universe, Monolagale appears as a case study in island-endemic mammal adaptation.
