NEOSANFILIPPIA
BRIAN, 1957
Type
species:
Neosanfilippia venezuelana
Brian, 1957
(m).
Diagnosis
Endoantennal conglobation. Eyes and pigment absent. Flagellum of second antenna two-jointed.
KEY TO SPECIES OF
NEOSANFILIPPIA
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
1.* Coxal plate 5 laterally convex. Cephalothorax and hind part of body without such ridges...................................................................................
Neosanfilippia venezuelana
Brian, 1957
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.
