Coecobrya tenebricosa
(Folsom, 1902)
Coecobrya tenebricosa is a cave-dwelling in the Entomobryidae. It belongs to the tenebricosa-group, characterized by the absence of , an unguis with one unpaired tooth, and a manubrium lacking smooth . The species has been recorded from multiple disjunct regions including the Caribbean mainland, Europe, Hawaii, Macaronesia, and the Mediterranean.

Identification
in the tenebricosa-group, including C. tenebricosa, are distinguished from other Coecobrya by the combination of: absence of (eyeless condition); unguis bearing one unpaired tooth; and manubrium without smooth . Within the tenebricosa-group, C. tenebricosa differs from similar species (C. communis, C. edenticulata, C. tropicalis) in details of chaetotaxy, mesothoracic chaetotaxy, and chaetotaxy.

Habitat
Cave-dwelling (troglobitic). As a member of the tenebricosa-group, this is adapted to subterranean environments.
Distribution
Recorded from Caribbean mainland, Europe, Hawaii, Macaronesia, and the Mediterranean region. The wide geographic disjunction of these records suggests either a broader natural distribution than currently understood or potential human-mediated .

Taxonomic History
Originally described as Sinella tenebricosa by Folsom in 1902, later transferred to Coecobrya. The Coecobrya was established by Yosii.
Group Characteristics
The tenebricosa-group within Coecobrya represents a morphologically cohesive of cave-adapted showing convergent troglobitic adaptations including reduction or loss and specialized chaetotaxy patterns.
