;

Etymology
. The specific name is a noun in apposition that refers to the
type
locality of the
holotype
.
Diagnosis
. Males of
Scytodes maromba
n.sp.
resemble those of
S. tacapepucu
Rheims & Brescovit
by the distal region of the male palp with a prolateral distal hyaline keel and a very long retrolateral sclerotized process (
Figs. 53–55
;
Rheims & Brescovit 2006
: 306, figs. 42–43). They are distinguished by the distal area of bulb longer than the sclerotized process (
Fig. 54
), by the smaller prolateral distal keel and by the presence of an additional prolateral subdistal keel (
Figs. 53, 55
).
