NEOSANFILIPPIA BRIAN, 1957 View in CoL

Type species: Neosanfilippia venezuelana Brian, 1957 (m).

KEY TO SPECIES OF NEOSANFILIPPIA View in CoL

1. Coxal plate 5 laterally concave. Cephalothorax with transverse ridge below the upper margin of the frontal shield. Coxal plates 6 and 7, pleon epimera 3–5 and uropod sympodites with strong ridge on their inner face.......................................................................... Neosanfilippia zoiai Manicastri, 1991 View in CoL 1.* Coxal plate 5 laterally convex. Cephalothorax and hind part of body without such ridges................................................................................... Neosanfilippia venezuelana Brian, 1957 View in CoL

Coxal plates without schisma. Male pereiopod 7 ischium with a ventrolateral process, which appears to be a membraneous structure; it does not bear any setae or scales. Pleopod exopodites without dorsal respiratory fields and without marginal setae. Uropods of same shape as in Scleropactes .

Relationships

The process on male ischium 7 was regarded as a putative synapomorphy shared with Amazoniscus ( Taiti et al., 1986) , but the processes may be not homologous: In Neosanfilippia , it seems to be an outgrowth of the articular membrane, which lacks scales or setae, whereas in Amazoniscus , it is a prolongation of the apical margin of the ischium.
