) is characterized by its dorso-ventrally flattened body with large and broad anterior pseudosegment showing longitudinal folds, the wide apart-set toes, and the 2 close-set light-refracting globules displaced to the right at the posterior of the brain. The specimens seen fit the original description, except for some details: the toes are more drawn-out and more or less distinctly offset near mid-length; the ‘ovate structure’ in the toes consists of a light-refracting spherical reservoir and part of its supply canal; the 4 dorsal longitudinal folds on the anterior trunk segment are 2 double-folds; the ‘spine’ between the toes is a rounded caudal papilla with projecting cilia.

Each ramus with single, slightly offset apical tooth set at right angle to trophi axis; cardal apophyses very small. Prior to apical teeth a preuncinal tooth set at a right angle to trophi axis; preuncinal teeth with elongate triangular head and short shaft forming obtuse angle; head with small cardal apophysis. Fulcrum longer than ramus, in dorsal/ventral view distal end slightly widening; distal widening indented dorsally, with median prominence ventrally; in lateral view with broad base, quickly tapering, continuing parallel-sided. Unci medium long, slightly curved, head shorter than shaft, with dorsal and ventral apophyses; dorsal and ventral ribs fairly broad. Intramallei long, sock-shaped, with relatively long, rounded medio-lateral basal expansion bearing opening medio-caudally; inner side expanded, fitting lateral concavity of rami. Supramanubria absent. Manubria slightly less incus length, stout, rod-shaped, proximal half straight, distal half incurved with crutched cauda, head short, triangular.
