Etymology. The specific name is a noun in apposition taken from the type locality, the Pululahua geobotanical reserve.

Diagnosis. Males resemble M. awa   n. sp. and M. hunachi   n. sp. but can be distinguished by the small curved embolic apophysis and the presence of a few, small cusps on a large retrolateral ledge ( Fig. 76 View FIGURES 76–80 ), while M. awa   n. sp. has a longer, pointed embolic apophysis and long cusps on a chisel ledge ( Fig. 46 View FIGURES 46–50 ) and M. hunachi   n. sp. has a no embolic apophysis and an elongated ledge with numerous, short cusps ( Fig. 94 View FIGURES 94–96 ). Females most resembles M. choco   n. sp. but can be distinguished by the extended anterior margin of the epigynum ( Fig. 79 View FIGURES 76–80 ); not as extended in M. choco   n. sp. ( Fig. 39 View FIGURES 36–40 ) and the large wing-like extension of the anterior margin of the dorsal plate ( Fig. 80 View FIGURES 76–80 ), straight in the latter ( Fig. 40 View FIGURES 36–40 ).

Description. Male (holotype): Total length: 1.92; carapace length: 0.94; carapace width: 0.86; abdomen length: 0.98. Cephalothorax: carapace dark brown, pear-shaped; suffused black along pars cephalica and radiating lines ( Fig. 71 View FIGURES 71–75 ). Sternum dark brown suffused with black; covered with long setae. Clypeus dark brown; high (4x AME). Chelicerae brown suffused with black; promargin with three teeth; retromargin not observed. Eyes: eight, rounded, all approximately equal size; ocular region on protuberance; AME separated by their radius, AME-LE touching; ALE-PLE contiguous, LE-PME separated by their diameter; PME separated by their radius. Abdomen: rounded, dark grey with white patches in a circular pattern anteriorly followed by longitudinal zigzag of white patches dorsally ( Figs 71, 72 View FIGURES 71–75 ). Legs: femur I dark brown; femora II-IV brown with dark brown patches baso-medio and apicoventrally, dark brown apically; tibiae and metatarsi I-IV orange-brown with dark band apically, tarsi light orange; femur and tibia I enlarged, metatarsus I slightly curved. Legs spination: patellae I-IV with one macroseta; tibia I with two prolateral clasping spurs; metatarsus I row of five macrosetae prolatero-ventrally and two clasping spurs apically ( Fig. 74 View FIGURES 71–75 ); femur I with one macroseta prolaterally; tibiae I-IV with one macroseta dorso-proximally; tibia II with four macrosetae ventrally. Total length leg I: 3.36 (1.16/0.35/0.94/0.44/0.47). Genitalia: palpal tibia globular; retrolateral ledge rectangular bearing five cusps, ventral ledge small with one cusp; two retrolateral trichobothria ( Fig. 76 View FIGURES 76–80 ). Cymbium apically truncated, excavated; paracymbium triangular and excavated prolatero-dorsally ( Fig. 77 View FIGURES 76–80 ). Tegulum oval ( Fig. 76 View FIGURES 76–80 ). Embolus short, spine-like, embolic apophysis curved, sickle-shaped ( Figs 76, 78 View FIGURES 76–80 ).

Female (allotype): Total length: 2.52; carapace length: 1.00; carapace width: 0.87; abdomen length: 1.52. Cephalothorax ( Fig. 71 View FIGURES 71–75 ), chelicerae and sternum: as in male. Clypeus dark brown; low (3x AME). Eyes: eight, rounded, all approximately equal size; ocular region on low protuberance; AME separated by their radius, AME-LE almost touching; ALE-PLE contiguous, LE-PME separated by their diameter; PME separated by their radius. Abdomen: as in male ( Figs 71, 73 View FIGURES 71–75 ). Legs: Legs: coloration pattern as in male, slightly darker; femur I enlarged with sub-apical short tubercle ( Fig. 75 View FIGURES 71–75 ). Legs spination: patellae I-IV with one macroseta; tibiae I-IV with one macroseta dorsoproximally; tibiae I-II with three to four macrosetae ventrally. Total length leg I: 3.41 (1.11/0.36/0.84/0.61/0.49). Genitalia: epigynum protruding, anterior epigynal margin extended but not well delimited, posterior epigynal margin pointed ( Fig. 79 View FIGURES 76–80 ). Dorsal epigynal plate anterior margin wing-like ( Figs 80 View FIGURES 76–80 , 226 View FIGURES 222–229 ). Internal genitalia (paratype): spermathecae large and rounded ( Figs 80 View FIGURES 76–80 , 227 View FIGURES 222–229 ); copulatory openings situated medially; copulatory ducts not observed; fertilization ducts procurved and well sclerotized basally, transparent and curved apically ( Figs 80 View FIGURES 76–80 , 227 View FIGURES 222–229 ).
