Calicina

Calicina species can be distinguished from other phalangodid genera by their distinctive body armor and genital morphology, though specific diagnostic features require examination by specialists. The genus is placed within the armored harvestmen based on the presence of well-developed scutes and heavy sclerotization. Species-level identification typically requires examination of male genitalia (penis structure) and detailed morphological analysis.

Species in the genus Calicina have been documented from caves and subterranean habitats, as well as surface environments in karst regions. Many phalangodid harvestmen, including Calicina, show associations with limestone cave systems and mesic microhabitats.

The genus is known from western North America, with records from California and surrounding regions. The type species and several others are documented from cave systems in this area.

As small predatory or detritivorous arthropods, Calicina species likely contribute to nutrient cycling and serve as prey for larger invertebrates and small vertebrates in cave and karst ecosystems. Their presence in subterranean habitats may indicate specific microclimatic conditions.

Calicina species have no direct economic importance to humans. Some species are of conservation interest due to their restriction to specific cave systems and vulnerability to habitat disturbance. The genus has been studied in the context of cave biodiversity and harvestman systematics.
