 pleural pieces elongate, cylindrical (in lateral outline, triangular) ; 

 with a deep groove on the ventral face ; outer face beset with long 

 hairs; apical appendage, elongate, hairy, the basal half rather fleshy,

 outer side at the base of the chitin, is a stout conical tooth; on 

 the inner face at the end of the fleshy portion of the arm is a fleshy,
