TYPES: Female holotype and female paratype from Bolivia: La Paz: Provincia de Sud Yungas, Municipio de Chulumani, comunidad de Paraíso, - 16.39488, - 67.55847, 2255 m, Oct. 13, 2011, to Oct. 18, 2011, Matías Izquierdo ( PBI_OON 42028 , PBI_OON 42026 ) GoogleMaps ; deposited in CBF; same data, one additional female paratype ( MACN-Ar 28199 PBI _ OON 42027) ; deposited in MACN-Ar.

ETYMOLOGY: The specific epithet is a patronymic in honor of Matías A. Izquierdo (MACN), participant of the PBI project, and collector of all known specimens, as well as many other South American oonopids.

DIAGNOSIS: Females differ from the other known species of the nigromaculatus group by the T-shaped anterior receptacle, with the stalk widening gradually toward the distal part (fig. 60C).

NOTE: Although the males of this species remain unknown, it is provisionally assigned to the nigromaculatus group because of the proportions of the tarsus-metatarsus of the forelegs (fig. 59B, C), the well-sclerotized carapace, and by the similar female genitalia.

DESCRIPTION: FEMALE (holotype, PBI_ OON 42028). Total length 1.92. Cephalothorax: Carapace orange, broadly oval in dorsal view (fig. 59D), pars cephalica strongly elevated in lateral view, anteriorly narrowed to less than half their maximum width; lateral margin straight; nonmarginal pars cephalica setae absent; nonmarginal pars thoracica setae absent; marginal setae dark, needlelike. Clypeus setae dark, needlelike. Eyes ALE, PME subequal, larger than PLE, all eyes circular; posterior eye row procurved from front; 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. Sternum as long as wide, pale orange, anterior margin unmodified, precoxal triangles present; setae sparse, dark, evenly scattered (fig. 59E). Mouthparts: chelicerae, endites, and labium pale orange; cheliceral setae light. Labium elongated hexagon, anterior margin indented at middle; with six or more setae on anterior margin. Palp spines absent. Abdomen: Dorsum pale white. Book lung covers ovoid. Postepigastric scutum pale orange. Spinneret scutum absent. Dorsum setae dark, needlelike. Postepigastric area setae dark, needlelike. Colulus represented only by setae. Legs: Pale orange; femur IV not thickened, same size as femora I–III, patella plus tibia I nearly as long as carapace. Leg spination: leg I: femora pv 0-0-1-1-0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2; leg II: femora d1-0, pv 0-0- 1-1-0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2; leg III: femora d1-1, tibiae p1-1, metatarsi p1-1, r1, v1-1ap; leg IV: femora d1-0-1, tibiae p1-0-1, r1-1, metatarsi p1-0-1, r1, v2ap. Trichobothria not examined. Genitalia: Dorsal view: anterior receptacle T-shaped, similar to an inverted triangle, with stalk widening gradually toward the distal part, and reaching the edge of the posterodorsal plate (fig. 60C).

MALE: Unknown.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the type locality, in the yungas forest of the Department of La Paz, Bolivia (map 6).
