Mamani, 1 male paratype ( MACN-Ar 23585 PBI _ OON 15010), 1 male and 2 female paratypes ( MACN-Ar 26077 PBI _ OON 30641), all deposited in MACN-Ar.

ETYMOLOGY: This specific epithet is a patronym in honor of Charles Darwin (1809– 1882), in commemoration of the recent 150th anniversary of the publication of On the Origin of Species and the 200th anniversary of his birth. A substantial and fruitful part of Darwin’s expedition took place in Argentina.

DIAGNOSIS: N. darwini males are very similar to those of N. tucumanus by the elongated bulb, but differ by the embolus being more strongly curved, and the conductor slightly bent upward at the apex and distally widened (fig. 26B). Females also resemble to those of N. tucumanus but the anterior receptacle is distally widened (fig. 26A).

DESCRIPTION: MALE (holotype, PBI_OON 14971).Total length 1.74. Cephalothorax: Carapace pale orange, ovoid in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width, cuticle surface with small platelets (as in fig. 3A), iridescent under light microscope; lateral margin undulate; nonmarginal pars cephalica setae absent; nonmarginal pars thoracica setae dark, needlelike; marginal setae dark, needlelike. Clypeus setae present, dark, stout, many stout erect setae reaching the ocular area. Eyes on a dark area, ALE largest, circular, PME oval, PLE oval; posterior eye row almost straight from front and recurved from above; ALE separated by more than their diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius (fig. 11C). Sternum longer than wide, yellow, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV; setae sparse, evenly scattered (fig. 11B). Mouthparts: chelicerae, endites, and labium yellow, cheliceral setae light, evenly scattered. Labium anterior margin indented at middle, with six or more setae. Endites distally not excavated, with a lateral expansion, membranous, with scalelike micosculpture, with a bunch of modified setae directed inward (fig. 12B). Abdomen: Dorsum white. Epigastric and postepigastric area with dark, needlelike setae. Postepigastric scutum yellow. Spinneret scutum absent. Dorsum with dark, needlelike setae. Colulus represented only by setae.

Genitalia: Palp (figs. 15, 17B– D, 20B): 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, more than two times as long as cymbium, slender, elongated, distal part with a forward-directed conductor, slightly curved apically, a flattened tip, and a narrow basal opening on its prolateral side (fig. 15C–F), probably for discharging the internal vesicle of the conductor. Embolus light; strongly curved, with a flattened opening (fig. 15F).

FEMALE (paratype, PBI_OON 14957). Total length 2.10. As in male except as noted.

DISTRIBUTION: Argentina, in Chaco, Corrientes, Entre Ríos, and northeast of Buenos Aires province (including Buenos Aires city), near the Paraná and La Plata rivers, and Uruguay (Río Negro). Probably also in intermediate localities along the Paraná coast (map 1).

NATURAL HISTORY: The largest series was collected by pitfall traps at the type locality, an urban ecological reserve near the Río de la Plata, in Buenos Aires city. These specimens were found in forests of Tessaria integrifolia ( Asteraceae , ‘‘aliso de río’’), but other individuals were also collected in highly disturbed neighboring areas, or in the bases of Cortaderia selloana (‘‘pampas grass’’) and other Poaceae . At El Palmar, many individuals were caught on the base of grasses ( Cortaderia and others), especially in swampy areas with diverse vegetation (both in grassland and forest formations). In Vuelta de Obligado, a female was collected during the night in the bank of the Paraná river, close to the entrance of a nest of the tiny ant Wasmannia auropunctata , suggesting that the spider could prey on them. Interestingly, another Argentine oonopid (the hard-bodied Gamasomorpha wasmanniae Mello-Leitão ) was collected in association with this ant species under stones, in Córdoba Province ( Birabén, 1954). Some specimens from the type locality and from Hudson are hosts of parasitoid acrocerid larvae (Shaun L. Winterton, identification from photographs). This could be the first report of the parasitoid relationship between acrocerids and oonopids. Most of the larvae were found inside the anterior part of the abdomen, near the booklungs (fig. 19B), although a few specimens are clearly visible in the cephalothorax (fig. 19C).
