( MACN-Ar 28229 PBI_OON 43362 ) . One male paratype from the same locality, in suspended soil, 3 Nov. 2011, Rubio G. (MACN-Ar 30116 PBI _ OON 42560) . Deposited In MACN-Ar.

ETYMOLOGY: The specific epithet is a patronym in honor of Luis N. Piacentini (MACN), one of the collectors of the only known specimens and also of many other oonopids in Argentina.

DIAGNOSIS: Males differ from the other known species of the nigromaculatus group by the conductor, which is L-shaped and not expanded (figs. 55B–D, 60D).

DESCRIPTION: MALE (holotype, PBI_OON 43362). Total length 1.60. Cephalothorax: Carapace orange, broadly oval 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 absent; nonmarginal pars thoracica setae dark, needlelike; marginal setae dark, needlelike. Clypeus setae dark, needlelike. Eyes ALE, PME subequal, larger than PLE, ALE oval, PME circular, PLE oval; posterior eye row procurved from front; ALE separated by less than their radius, ALE-PLE touching, PME touching for less than half their length, PLE-PME separated by less than PME radius. Sternum longer than wide, yellow-brown, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV; setae abundant, densest laterally (fig. 54E). Mouthparts: chelicerae, endites, and labium pale orange; cheliceral setae dark, evenly scattered. Labium anterior margin indented at middle; with six or more setae on anterior margin. Endites distally not excavated, anterolateral membranose lobes. Abdomen (crushed): Dorsum white. Book lung covers elliptical. Postepigastric scutum pale orange. Spinneret scutum absent. Dorsum setae dark, needlelike. Colulus represented only by setae. Legs: Orange. Leg spination: leg I: femora d1, pv0-0-1-1-0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2; leg II missing; leg III: femora d1-1, tibiae d1, p1-1, r1-1, v1-1ap, metatarsi p1-1, r1-1, v2ap; leg IV: femora d1-1-1, tibiae d1-1, p1-1, r1-1, v1- 1ap, metatarsi p1-1, r1-1, 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 yellow, more than two times as long as cymbium, stout, tapering apically, basally globose, abruptly tapering toward the distal part, distal part of conductor L-shaped, not expanded; embolus dark (figs. 55B–D, 60D).
