Glomeris aurita

Glomeris aurita exhibits polymorphism and individuals can be found together in two different colour morphs, either expressing a yellow or orange colouration on their thoracic shield.^[3] The rest of G. aurita's body, regardless of the morph, is black in colour.^[3] Glomeris aurita also possesses a prominent stria on its main thoracic shield, which is a feature not shared by other pill millipedes within its natural range.^[3]

Glomeris aurita is a microendemic species, native only to the Bergamasque Alps of Northern Italy. G. aurita is a high-altitude species, found inhabiting alpine meadows at altitudes ranging from 1400 to 2400 meters above sea level.^[3] The alpine meadow habitat is notable as it is an unusual habitat for pill millipedes, which usually inhabit forest habitats.^[1]

It is believed that the active period of Glomeris aurita on the surface, extends from June to the middle of September, encompassing only 3.5 out of 12 months of the year.^[3] It is also believed the species may inhabit the cool sheltered environments of mountain caves.^[3] G. aurita had previously been listed as a species encountered within caves east of Lago di Como by Manfredi (1932).^[3] Nevertheless, specimens of G. aurita from alpine meadow habitat in the Bergamasque Alps do not exhibit any indications of adaptations associated with cave environments.^[3]
