Type species Paramblyops rostrata Holt & Tattersall, 1905, by original designation according to ICZN (1999). Diagnosis Based on adults of both sexes. Eye rudiments without stalk, separate, not connected by membranous integument, positioned laterally, each reduced to roughly triangular or rectangular pads with only disto-lateral edge produced into a tooth-like non-sensory projection, no visual elements, no ocular papilla. Antennular trunk with three segments separated by transverse articulations; basal segment without ventral carina. Antennal scale not subdivided, bare portion of lateral margin distally ending in a single, strong tooth; mesial margin setose all along. Antennal peduncle with three segments lined in a single plane. Thoracomeres and pleomeres normal. Thoracic endopod 2 not prehensile. Endopods 3–8, as far as known, with oblique articulation between carpus and propodus. Female pleopods representing setose rods with residual differentiation of pseudobranchial lobe. Male pleopods biramous, with well-developed sympod and multi-segmented exopod. Endopod 1 short, unsegmented; endopods 2–5 long, multi-segmented; all endopods with small, setose ...
