Dromidiopsis tridentate   Borradaile,  1903 (Crab)
Organism information awaits expert curation
Class: Malacostraca

Carapace approximately as long as wide. Last two segments of abdomen fused or partially fused. Inner margins of first two pairs of leg armed with four-five spines, two spines on outer propodal margin of third leg, dactyl of fourth leg opposed by two spines. Last leg long, almost reaching supraorbital margin when extended forward.

The carapace is as long as broad and is covered by a short tomentum. The median frontal tooth is small and hardly visible in dorsal view. There is no supraorbital tooth and the inner orbital angle is not marked. There is a fissure between the outer orbital angle and the infraorbital lobe. The anterolateral margin of the carapace bears three small teeth; two of these are placed close to the orbit. The cheliped has an epipodite. The upper margin of the palm of the chelipeds carries three granules, which can be observed only after the removal of tomentum. P2 and P3 are robust and smooth. The dactylus is slightly shorter than the propodus. The margins of the segment of P4 and P5 carry long plumose setae. P4 is shorter than P5. P5 has two spines in that region, one of which is quite small and therefore easily overlooked. The telson of the male is as broad as long (the breadth assured at the base). The fifth and sixth abdominal somites are fused.
