Eta (η) hourglass-shaped dorsal scutum. Ocularium conical, pointed forward, longer than all other species of Maurymontia adorned with granules. Eyes are proximally located in the dorsolateral view of the ocularium. The dorsal scutum reveals well-defined areas covered by small tubercles. Areas I–III possess a pair of small tubercles with setae, while area IV has 5─8 tubercles. The posterior border is adorned with six tubercles, and lateral grooves of the dorsal scutum are bifurcated on each side. Free tergites are covered by tubercles, bearing sparse setae.</p><p>Venter (Figs 3 E, 4 C–D). Coxa I displays a medial tubercle with subdistal seta and 7–9 small tubercles with setae. Coxa II and IV microgranulate in the distal part, coxa III lacks microgranulation, and coxa IV has small tubercles in the distal part, without a bridge in the coxa IV. Spiracles are visible. The sternum is arrow-shaped.</p><p>Chelicerae (Fig. 5 A–B). Segment I of the chelicerae has five small tubercles on the ectal surface, 8–9 small tubercles on the meso-ventral surface, and a small acute tubercle on the dorso-distal surface.

Mesal area covered by small rounded tubercles and two distal conical tubercles with subdistal setae. Patella has an ectal and mesal tubercle with subdistal setae. Tibia is covered ventrally by small rounded tubercles and has three ventral tubercles with subdistal setae on each side. Tarsus has three ventral tubercles with subdistal setae on each side and small scattered ventral tubercles with subdistal setae (~10).</p><p>Legs (Fig. 6).

The noun in apposition maintains the original orthography of this geographically significant site.</p><p>Diagnosis. This species can be easily distinguished from the other species of the genus by having more robust tubercles on the free tergites and a ventral plate of the penis with an arched shape and a central portion that is more elevated (slightly triangular), the long dual-lobed end of the capsula externa, and single shorter projection on the dorsal side.</p><p>Measurements holotype (MACN-Ar 46024): Total length 2.11; carapace length 0.81, maximum width 1.25; dorsal scutum length 1.70; mesotergal scute maximum width 1.46.

Eta (η) hourglass-shaped dorsal scutum. Ocularium conical, prominently projected forward, with the dorsal surface adorned with granules. Eyes are proximally located in the dorsolateral view of the ocularium. The anterior margin has 4–5 tubercles each side. The dorsal scutum reveals well-defined areas covered by small tubercles. Areas I–III possess 2–3 small tubercles with setae, while area IV has 4─6 tubercles. Free tergites are covered by robust tubercles, some bearing setae.</p><p>Venter (Figs 24 D, 25 C–D). Coxa I displays a medial tubercle with subdistal seta and 6–8 small tubercles with setae. Coxa II microgranulate in the distal part, coxa III lacks microgranulation, and coxa IV distal microgranulate, bearing distal tubercles. Spiracles are visible. The sternum is arrow-shaped.</p><p>Chelicerae (Fig. 26 A–B). Segment I of the chelicerae has four small tubercles on the ectal surface, seven small tubercles on the meso-ventral surface, and a small acute tubercle on the dorso-distal surface. Segment II exhibits ~six small tubercles in ectal view, 8–9 in mesal view, and nine in frontal view.</p><p>Pedipalp (Fig. 26 C–D). Trochanter with two dorsal tubercles and one ventral tubercle with subdistal setae, ventral surface microgranulate that extend to the femur. Femur with a ventro-ectal tubercle and a row of small tubercles with setae in dorso-ectal view. There is a row of conical tubercles interspersed with small tubercles in the dorsal view. Mesal area covered by small rounded tubercles and three distal conical tubercles with subdistal setae. Patella has an ectal and mesal tubercle with subdistal setae. Tibia is covered ventrally by small rounded tubercles and has three ventral tubercles with subdistal setae on each side. Tarsus has three ventral tubercles with subdistal setae on each side and small scattered ventral tubercles with subdistal setae (~8).</p><p>Legs (Fig. 27). Leg I trochanter with two dorsal tubercles, femur with a row of dorsal and ventral long tubercles, smooth patella, tibia with a ventral row of tubercles, metatarsus and tarsus smooth, II–IV with small setiferous tubercles on the femur, astragalus larger than the calcaneus on all legs, tarsal count: 2-3-3-3.</p><p>Penis (Fig. 28). Pars distalis with a ventral plate, without a cleft, forming a lamella with triangular shape, longer than wide, with three ventral and two dorsal macrosetae each side; dual-lobed capsula externa higher than the ventral plate, with a single shorter projection on the dorsal side, surrounding the stylus; capsula interna tubular in shape, longer than the capsula externa.</p><p>Female</p><p>Measurements female (MACN-Ar 47793): Total length 2.67; carapace length 0.80, maximum width 1.25; dorsal scutum length 1.65; mesotergum maximum width 1.74.
