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

Diagnosis. This species most resembles M. angamarca n. sp. and M. cienaga but can be distinguished by the epigynum with dark sclerotized band sub-apically ( Fig. 84 View FIGURES 81–85 ), apical in M. angamarca n. sp. ( Fig. 89 View FIGURES 86–90 ); from M. cienaga by the femur I with a pointed tubercle ( Fig. 83 View FIGURES 81–85 ), absent in the latter ( Baert 1990).

Description. Female (holotype): Total length: 2.87; carapace length: 1.0; carapace width: 0.87; abdomen length: 1.87. Cephalothorax: carapace dark brown, pear-shaped; suffused black along pars cephalica and radiating lines ( Fig. 81 View FIGURES 81–85 ). Sternum dark brown; covered with long setae. Clypeus dark; high (4x AME). Chelicerae dark brown suffused black; promargin with three teeth; retromargin not observed. Eyes: eight, rounded, all approximately of equal size; ocular region on protuberance; AME separated by their diameter, AME-LE touching; ALE-PLE contiguous, LE-PME separated by their diameter; PME separated by their diameter. Abdomen: oval, light grey with white patches in hourglass pattern ( Figs 81, 82 View FIGURES 81–85 ). Legs: femur I dark brown, femora II-IV light yellow with basal, medial and apical dark band; tibiae and metatarsi II-IV light yellow with apical dark band, tarsi light yellow; femur I enlarged with small, medial tubercle ( Fig. 83 View FIGURES 81–85 ). Legs spination: patellae I-IV with one macroseta; tibiae I-IV with one macroseta dorso-proximally; tibiae I-II with three to four macrosetae ventrally. Total length leg I: 3.52 (1.15/0.4/0.89/0.6/0.48). Genitalia: epigynum protruding, anterior epigynal margin not well delimited, posterior epigynal margin rounded with sub-apical dark, sclerotized rim ( Fig. 84 View FIGURES 81–85 ). Dorsal epigynal plate with wing-like anterior margin ( Fig. 85 View FIGURES 81–85 ). Internal genitalia with large and rounded spermathecae; copulatory ducts not observed; fertilization well sclerotized basally, curved, semi-transparent and curving apically ( Fig. 85 View FIGURES 81–85 ).

Male: Unknown.

Distribution. Only known from the type locality in Pichincha Province.

Natural history. The holotype specimen was collected in a Linothele sp. web at 2719m in the Andean ecoregion. M. lloa n. sp. inhabit the evergreen mountain forest of the western Andes (BsMn03) ( Aguirre, Toasa & Gálvez 2013).
