PBI
_OON 140).
Paratype
: one female, same data as
holotype
(

type
locality.

, male: 168–170 habitus (168 ventral, 169 dorsal, 170 lateral); 171–172 cephalothorax (171 dorsal, 172 ventral); 173–175 abdomen (173 lateral, 174 ventral, 175 dorsal); 176–178 left bulb (176 retrolateral, 177 ventral, arrow on embolar prolateral prong; 178 prolateral, detail.

, female: 179–181 habitus (179 dorsal, 180 ventral, 181 lateral); 182–185 cephalothorax (182 ventral; 183 dorsal, 184 anterior, 185 lateral); 186 epigastric area, ventral; 187–188 abdomen (187 lateral, 188 ventral, arrow on groove pocket.
Diagnosis
. Males resemble those of
N. hispidus
(See
Abrahim
et al
. 2012
, figs 201, 202),
N. furtivus
(See
Abrahim
et al
. 2012
, figs 297, 299) and
N. yekuana
sp. nov.
(
Figs 139, 141
) by presenting both carapace and abdominal dorsal scutum texturized (
Figs 171, 175
). They differ from those of
N. yekuana
sp. nov.
(
Figs 145, 146
) and
N. furtivus
(See
Abrahim
et al
. 2012
, figs 284, 285) by the presence of denticles on the dorsal abdominal scutum and from those of
N. hispidus
(See
Abrahim
et al
. 2012
, figs 208) by having a basal prong on the prolateral margin of embolus (
Fig. 177
). Females resemble those of
N. hispidus
(See
Abrahim
et al
. 2012
, figs 201, 213),
N. furtivus
(See
Abrahim
et al
. 2012
, figs 305, 309),
N. coca
sp. nov.
(
Figs 66, 68
) and
N. yekuana
sp. nov.
(
Figs 161, 163
) by presenting both carapace and abdominal dorsal scutum texturized (
Figs 183, 187
). They differ from those of
N. yekuana
sp. nov.
(
Fig. 162
) by the low clypeus, slightly more than one AME diameter in height (
Fig. 184
); from those of
N. furtivus
(Fig. 308) by the presence of enlarged setal sockets on the carapace posterior surface (
Figs 183, 185
); from those of
N. hispidus
(See
Abrahim
et al
. 2012
, fig. 216) by the median element without accessory prongs (
Fig. 16
) and from those of
N. coca
sp. nov.
(
Fig. 70
) by the deep pockets on laterals of the groove connecting posterior spiracles (
Figs 16
,
186
).
