Monapia carolina Ramírez, 1999: 427 .

DIAGNOSIS: See Ramírez (1999). Males are very similar to those of Monapia fierro in genitalia, but they can be distinguished by having a longer tip on the paramedian apophysis.

FEMALE: See Ramírez (1999).

MALE (Pampa de Achala): Total length 5.32. Carapace length 2.63, width 2.03. Length of tibia/metatarsus: I, 1.97/1.70; II, 1.70/1.50; III, 1.50/1.50; IV, 2.07/2.47. Chelicerae slightly narrower than those of female. Sternum length 1.47, width 1.10. Spines: leg I, femur d 1–1–1, p 0­ 0­ 1­ d1, r 1ap; tibia with two rows of ventral spines, six prolateral, five retrolateral, approximately 2­ 2­ 2­ 2­ p1­ 2 (left) and 2­ 2­ 2­ p1­ 0­ 2 (right), p and r 1–1; metatarsus v 2bas, p and r 1, d 0­ p1–2. II, femur d 1–1–1, p and r 0­ d1­ d1; tibia v 2­ 2­ 2­ 0­ 2, p and r 1–1; metatarsus = I. III, femur = II; patella r d1; tibia v 2–2– 2 (the r1bas smaller), p and r 1–1; metatarsus v 2–0–2, p and r d1–1–1, d 0­ p1–2. IV, femur d 1–1–1, p and r 1ap; patella and tibia = III; metatarsus v 2–2–2, p and r d1–1–1, d 0­ p1–2. Abdomen length 2.73, width 1.63, spiracle–epigastrium 1.07, spiracle spinnerets 0.43. Color as in female. Palp (fig. 139A–D): tibia width/length 0.79. Retrolateral margin of cymbium with slight basal notch. Sperm duct with anterior ventral loop not evident. Embolus thick, sinuous. Apex of paramedian apophysis thin, hook­shaped. Primary conductor triangular. Secondary conductor divided by membranous area with blunt lobe close to retrolateral portion; prolateral portion curved, flattened; canal wide, crossed by diagonal sclerotized stripe; retrolateral portion with thick base, long, flattened apex; retrolateral portion separated from anterior margin of tegulum by suture, prolateral portion separated by membranous area.

NATURAL HISTORY: All specimens from Pampa de Achala were collected on grasses; at that time (31 August, winter) the nine adult females collected were ovigerous.

Monapia angusta (Mello­Leitão) Figure 139E–H

Arachosia angusta Mello­Leitão, 1944: 357 (holotype immature from Argentina, Buenos Aires province, Tigre, Río Guayraca´, in MLP 16100, not reexamined).

Monapia angusta : Ramírez, 1999: 422.

DIAGNOSIS: See Ramírez (1999). Males resemble those of Monapia guenoana in having an anterior cheliceral spine, but can be distinguished by having a thicker embolus.

FEMALE: See Ramírez (1999).

MALE (San Isidro): Total length ca. 6.15. Carapace length 2.17, width 1.37. Length of tibia/metatarsus: I, 3.86/3.10; II, 2.53/1.97; III, 1.35/1.10; IV, 3.59/2.67. Chelicerae small, narrow, anterior face with black spot, thick spine close to clypeus. Sternum length 1.25, width 0.87. Spines: leg I, femur d 1– 1–1, p 0­ 0­ v1­ d1 and an oblique apical line of thick bristles, r 1ap; tibia v 2­ 2­ 2­ 2­ 0, d r1–1 bristles; metatarsus v 2–2–2(probably the p and r displaced)­ 0–0, d 2­ p1­ r1­ 0­ 2. II, femur d 1–1–1, p and r d1ap; tibia v 2­ r1­ 2­ r1­ 2 (both x­r1­ x­r1­ x are probably the r d1– 1 displaced), p d1–1, d r1–1 bristles; metatarsus v 2­ r1(probably the r displaced)­ r1–0, p 1–0, d p1–2. III, femur d 1–1–1, p 0­ d1­ d1, r d1ap; tibia v p1­ p1–0, p and r d1–1, d r1–1; metatarsus v 2–0–1 or 2bas, p 0­ d1–1, r 0­ v1­ v1, d p1–2. IV, femur d 1–1–1; tibia v 2–2–2, p and r d1–1, d r1–1; metatarsus v 2­ (p1­ r1)­ 1, p d1–1–1, r d1–1–1 (very large), d 0­ p1–2. Abdomen length ca. 2.40, width 0.90 (wrinkled and curved), spiracle–epigastrium ca. 0.80, spiracle spinnerets ca. 0.73. Color as in female. Palp (fig. 139E–H): tibia very long, width/length 0.38. Copulatory bulb partially distended (specimen recently moulted). Sperm duct passing through anterior ventral margin of tegulum. Embolus very thick, suddenly narrowed distally, medial ventral portion not sclerotized. Paramedian apophysis poorly developed, tip curved, hook­shaped. Primary conductor absent. Secondary conductor totally divided by membranous area, both portions well separated from anterior margin of tegulum, prolateral portion quite reduced; base of retrolateral portion thin, deeply notched; area corresponding to canal wide, not sclerotized.
