Tridentodillo
Tridentodillo is a genus of woodlice belonging to the family Armadillidae. This genus was described in 1933 by Harold Gordon Jackson. The type specimen for this species is Tridentodillo squamosus from the Marquesas Islands in French Polynesia, and it is the only species in this genus.
Description
In the genus Tridentodillo, the edge of the frontal shield is layered and strongly raised above the thorax, forming a broad triangular shape in the middle. The side edge of the first body segment is thin and unbroken. On the underside of this segment, set in from the side edge, there is a long, deep fold that runs along the length of the segment and ends at the rear in a prominent, semicircular flap.The movable flap on the second body segment is tooth-shaped and extends well beyond the rear edge of the segment. The front and rear corners of the first three side plates are reduced, giving them a sharp outer edge. The remaining exposed thoracic and abdominal segments have roughly square outlines and do not extend outward.
The head and each thoracic segment have three very long, slender, curved spines along their rear edges, while the abdominal segments lack spines entirely.
