Grismado, M. Izquierdo, F. Labarque, G. Rubio, M. Burger, P. Michalik, P. Carrera( MACN-Ar 17988 PBI_OON 14889and MACN-Ar 17720 PBI_OON 14883respectively). Deposited in MACN-Ar.  ETYMOLOGY: The specific name refers to the Yungas clouded forests of the northwestern Argentina.  DIAGNOSIS: Males share with those of  N. nigromaculatusand  N. rubioithe dorsal sclerotized stripe on the abdomen (figs. 34A, D, 35A), but differ by the more widened, almost translucent conductor (figs. 40D, 35B–D). Females also resemble those of  N. nigromaculatus, but the anterior receptacle is basally narrow and abruptly widened distally (figs. 36H, 40C).  DESCRIPTION: MALE ( holotype, PBI_OON 14889). Total length 1.60. Cephalothorax:Carapace brown, ovoid in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width; lateral margin straight; nonmarginal pars cephalica setae dark, needlelike, scattered; nonmarginal pars thoracica setae dark, needlelike; marginal setae dark, needlelike (fig. 34A, C, D, F). Clypeus setae absent. Eyes all subequal, ALE circular, PME oval, PLE oval; posterior eye row procurved from front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum (fig. 34E) as long as wide, yellow-brown, anterior margin unmodified, posterior margin extending posteriorly beyond anterior edges of coxae IV as single extension; setae sparse, densest laterally. Mouthparts: chelicerae, endites, and labium yellow-brown, cheliceral setae dark, evenly scattered. Labium anterior margin indented at middle; with one or two setae on anterior margin. Endites distally not excavated, anterior part of each endite less sclerotized, projecting anteriorly as a membranose lobe, with distolateral pointed projections (fig. 34E). Abdomen:Dorsum pale white, without color pattern, with an anterodorsal brown sclerotized stripe, reaching around one third of its length; surface smooth (figs. 34A, C, 35A). Postepigastric scutum yellow-brown. Spinneret scutum absent. Dorsum setae dark, needlelike. Colulus represented only by setae. Spinnerets: ALS: cylindrical, pale; PMS: pale; PLS: pale, the longest. Legs:Yellowbrown; femur IV not thickened, same size as femora I–III. Leg spination: leg I: femora pv0-0-1-1-0, tibiae v2-2-2-2-2-0, metatarsi v2- 2-2; leg II: femora pv0-0-1-0, tibiae v2-2-2-2- 2-0, metatarsi v2-2-2; leg III: femora d1-1-0, tibiae p1-0-1, v0-0-2; leg IV: femora d1-1-0, tibiae r1-0-0, v0-1-1ap, metatarsi d0-0-1, p0- 0-1, r1-0-1, v1-2ap. Trichobothria not examined. Genitalia(figs. 35B–D, 40D): Palp proximal segments orange-brown; femur normal size, two or more times as long as trochanter; cymbium orange-brown, ovoid in dorsal view, not fused with bulb; bulb orangebrown, 1 to 1.5 times as long as cymbium, stout, tapering apically, distal prolateral conductor translucent, lamellar, widened distally, touching the darkened embolus.  Fig. 35.  Neotrops yunga, new species, A,male PBI_OON 14765, B–D,male PBI_OON 14889).  A.Carapace, anterior view. B–D.Palp. B.Dorsal view. C.Prolateral view. D.Retrolateral view.  Fig. 36.  Neotrops yunga, new species, female PBI_OON 14883. A.Habitus, dorsal view. B.Same, ventral view. C.Same, lateral view. D.Carapace, dorsal view. E.Cephalothorax, ventral view. F.Same, lateral view. G.Same, anterior view. H.Epigynum, ventral view. FEMALE ( paratype, PBI_OON 14883). Total length 1.84. As in male except as noted. Cephalothorax:Carapace yellowbrown (fig. 36D), broadly oval in dorsal view; nonmarginal pars cephalica setae dark, needlelike. Clypeus setae, dark, needlelike, two long setae forwardly directed. Sternum: precoxal triangles present; setae dark. Labium elongated hexagon; with six or more setae on anterior margin. Palp spines absent. Abdomen:Dorsum lacks the anterodorsal brown sclerotized stripe of the male (fig. 36A). Postepigastric area setae dark, needlelike. Spinnerets: ALS: cylindrical, pale, longest; PMS: pale; PLS: pale, conical. Legs:Patella plus tibia I nearly as long as carapace. Leg spination: leg I: femora d0-1-0, pv0-0-1- 1-0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2; leg II: femora d0-1-0, p0-0-1-1-0, tibiae v2-2-2-2- 2-0, metatarsi v2-2-2; leg III: femora d1-1, tibiae p1-1, r1-1, v0-1-2ap, metatarsi p1-1, r1- 1, v1-0-2ap; leg IV: femora d1-1, tibiae p1-1- 0, r0-0-1, v0-1-1ap, metatarsi d0-0-1-1, r0-1- 0, v0-0-1ap. Genitalia(figs. 36H, 40C): Anterior receptacle visible through cuticle in ventral view. Dorsal view: anterior receptacle with a thin, long stalk and abruptly widened anterior tip. Accessory glands present on base and stalk. Posterodorsal plate nearly circular, large, covering dorsally the anterior receptacle.  OTHER MATERIAL EXAMINED:   ARGENTINA:  Jujuy:same data as the types, 1♀( MACN-AR 17725 PBI_ OON14885); same locality,  1100 m,  Oct. 05, 1997, to  Oct. 07, 1997, Ramírezand Compagnucci, 18 ( MACN-AR 15374 PBI_ OON14765);   850 m, -23.74277 °, -64.85361 °,  Oct. 20, 1994, J.
