Calicina sequoia
(Briggs & Hom, 1966)
Calicina sequoia is an armoured in the Phalangodidae, first described by Briggs and Hom in 1966. It was originally placed in the Sitalcina before being transferred to Calicina. The species epithet 'sequoia' suggests an association with giant sequoia (Sequoiadendron giganteum) . Like other phalangodid harvestmen, it possesses a heavily sclerotized body with distinctive armoured plates.

Appearance
As an armoured in the Phalangodidae, the body is heavily sclerotized with prominent plates. The body form is compact with relatively short legs compared to many other harvestman families. Specific morphological details for this are not well documented in available sources.
Habitat
The epithet 'sequoia' and original description suggest association with giant sequoia (Sequoiadendron giganteum) forest . Based on the distribution of related species and the locality, it likely inhabits moist, shaded forest environments with decaying wood and leaf litter.
Distribution
Found in North America. The specific locality and precise range are not detailed in available sources, but the name suggests occurrence in the Sierra Nevada region of California where giant sequoias are .
Ecological Role
As a litter-dwelling , it likely contributes to decomposition and serves as for larger and small vertebrates. Specific ecological functions for this have not been documented.
