ETYMOLOGY: This specific epithet is a noun in apposition taken from the
type
locality.
DIAGNOSIS:
N. caparu
males are very similar to those of
N. kopuchianae
by the shape of the bulb and its terminal elements, but differ by the bulb less tapering distally, and in having a small protrusion in the embolus, where the filiform part arises (figs. 101B, 109B). Females also resemble those of
N. kopuchianae
by the T-shaped anterior receptacle, but the transverse distal projections are shorter (fig. 109A).
DESCRIPTION: MALE (
holotype
, PBI_OON 43162). Total length 1.66.
Cephalothorax:
Carapace yellow-brown, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to less than half their maximum width; lateral margin straight; nonmarginal pars cephalica setae dark, needlelike; nonmarginal pars thoracica setae dark, needlelike; marginal setae dark, needlelike. Clypeus setae dark, needlelike. Eyes: ALE, PLE larger than PME, ALE circular, PME oval, PLE circular; posterior eye row straight from front; ALE separated by their radius to diameter, ALE-PLE touching, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide, yellow, anterior margin with semicircular depression in the middle, posterior margin not extending posteriorly of coxae IV (fig. 100E); setae sparse, evenly scattered. Mouthparts: chelicerae, endites, and labium pale orange; cheliceral setae light, evenly scattered. Labium anterior margin indented at middle; with six or more setae on anterior margin. Endites distally not excavated, anteromedian tip with backward folded ridge, with anterior lateral expansions, with ectal ridges that continue the ventral folded structures (fig. 100E).
Abdomen:
Dorsum white. Book lung covers round. Postepigastric scutum yellow. Spinneret scutum absent. Dorsum setae dark, needlelike. Colulus represented only by setae.
Legs:
Yellow; femur IV slightly thickened. Leg spination: leg I: femora d1-0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2-2; leg II: femora d1-0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2-2; leg III: femora d1, tibiae d1, p1-1, metatarsi d1subap, r1-1, v2ap, p1subap; leg IV: femora d1-0-0, tibiae p1-1, r1-1, v1, metatarsi d1, p0- 1, r0-1, v1-2ap. Trichobothria not examined.
Genitalia:
Palp proximal segments pale orange; femur normal size, two or more times as long as trochanter; cymbium pale orange, ovoid in dorsal view, not fused with bulb; bulb pale orange, 1 to 1.5 times as long as cymbium, slender, tapering apically; embolus dark, distal half threadlike, proximal half thicker; boundary of both sections with short, dorsal branch; embolus with filiform distal sector (figs. 101B, 109B); conductor with small, translucent, acute tip (figs. 101B– D, 109B).
FEMALE (
paratype
, PBI_OON 43162). Total length 1.98. As in male except as noted.
Cephalothorax:
Carapace pars cephalica strongly elevated in lateral view. Sternum anterior margin unmodified, precoxal triangles present; setae dark. Labium elongated hexagon. Palp spines absent.
Abdomen:
Postepigastric area setae dark, needlelike.
Legs:
Patella plus tibia I nearly as long as carapace. Leg spination: leg I: femora d1-0, tibiae v2-2- 2-2-2-0, metatarsiv2-2-2-2; leg II: femora d1- 0, tibiae v2-2-2-2-2-0, metatarsiv2-2-2-2; leg III: femora d1-1, tibiae d1, p1-0, v1-1ap, metatarsi d1-1, r1-1, v1ap, p0-1; leg IV: femora d1-1-1, tibiae d1, p1-1, r1-1, v1-1ap, metatarsi d1-1, p1-1, r1-1, v1-2ap.
Genitalia:
Dorsal view: anterior receptacle relatively narrow, distal part slightly expanded laterally; posterodorsal plate oval, elongated, reaching tip of anterior receptacle (fig. 109A).
