Etymology. The specific name is in honor of Fernanda María Salazar, collection manager at Museum of Invertebrates, Pontificia Universidad Católica del Ecuador, Quito, for her contribution to the study of the Ecuadorian insect fauna.

Diagnosis. Male are distinguished from all species by the presence of one tibial clasping spur accompanied by four large macrosetae ( Fig. 157 View FIGURES 154–158 ) and a large, forked-shaped embolic apophysis ( Figs 159, 161 View FIGURES 159–163 ). Females are distinguished from all species by the combination of the following characters: the presence of three macrosetae prolater- ally on femur I ( Fig. 158 View FIGURES 154–158 , arrow), the sinuous posterior margin of epigynum and large S-shaped fertilization ducts ( Figs 162, 163 View FIGURES 159–163 ).

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 six white spots in circular pattern anteriorly ( Fig. 154 View FIGURES 154–158 ) followed by transversal line of six white spots and two pairs of white spots ( Fig. 155 View FIGURES 154–158 ). Spinnerets: ALS with one major ampullate gland spigot, 11 piriform spigots, a nubbin and a tartipore; PMS with one minor ampullate gland spigot, two aciniform gland spigots; PLS with one flagelliform, six aciniform gland spigots ( Figs 202, 204, 206 View FIGURES 200–207 ). Legs: femur I orange-brown; femora II-III light orange-brown with faint darker bands basally and apically; femur IV light orange-brown; tibiae and metatarsi I-IV light orange-brown with dark band apically, tarsi light orange; femur and tibia I enlarged, metatarsus I straight ( Fig. 157 View FIGURES 154–158 ). Legs spination: patellae I–IV with one macroseta; tibia I with one prolateral clasping spur and four macrosetae ( Fig. 210 View FIGURES 208–215 ); metatarsus I with row of six macrosetae prolatero-ventrally and one clasping spur apically ( Figs 157 View FIGURES 154–158 , 212 View FIGURES 208–215 ); tibiae I–IV with one macroseta dorso-proximally; tibia II with three macrosetae ventrally. Total length leg I: 3.04 (0.87/0.29/0.79/0.5/0.59). Tarsal organ capsulate ( Fig. 208 View FIGURES 208–215 ). Genitalia: palpal tibia globular; retrolateral ledge with wide projection with 12 cusps fused with ventral ledge bearing two cusps; two retrolateral trichobothria ( Fig. 159 View FIGURES 159–163 ). Cymbium apically pointed, not excavated; paracymbium small and triangular ( Fig. 160 View FIGURES 159–163 ). Tegulum squared ( Fig. 159 View FIGURES 159–163 ). Embolus spine-like, with large, curved base and forked basal embolic apophysis ( Figs 159, 161 View FIGURES 159–163 , 214 View FIGURES 208–215 ).

Female (allotype): Total length: 2.16; carapace length: 1.01; carapace width: 0.84; abdomen length: 1.15. Cephalothorax ( Fig. 154 View FIGURES 154–158 ) and sternum: as in male. Chelicerae promargin with three teeth and retromargin with one tooth ( Fig. 209 View FIGURES 208–215 ). Clypeus dark brown; low (3x AME) ( Fig. 201 View FIGURES 200–207 ). Eyes: eight, rounded, all approximately of equal size; ocular region on lower protuberance; AME separated by their radius, AME-LE touching; ALE-PLE contiguous, LE- PME separated by their radius; PME separated by their radius. Abdomen: as in male ( Figs 154, 156 View FIGURES 154–158 ). Spinnerets: ALS with one major ampullate gland spigot, 11 piriform spigots, a nubbin and a tartipore; PMS with one minor ampullate gland spigot, two aciniform and one cylindrical gland spigots; PLS with two cylindrical, one flagelliform and six aciniform gland spigots ( Figs 203, 205, 207 View FIGURES 200–207 ). Legs: coloration darker than male; femur I enlarged with large sub-medial tubercle ( Fig. 158 View FIGURES 154–158 ).

Distribution. Ecuador: Orellana, Pastaza and Sucumbios Provinces.

Natural history. Specimens were collected in the Amazonian ecoregion, in several Linothele   sp. and Lycosidae   webs between 200– 919m. The species is widely distributed from the evergreen foothill forest on the Northeastern Andes (BsPn03) ( Guevara, Mogollón, Cerón & Josse, 2013) to the evergreen lowland forest of the Amazonian region from Rio Aguarico (BsTa02) ( Guevara, Pitman, Mogollón, Cerón & Palacios, 2013) to Rio Paztaza (BsTa03) ( Guevara, Pitman, Mogollón, Cerón & Loarte, 2013). M. salazarae   n. sp. lives in sympatry with M. bartolozzi   n. sp. in Pastaza and Sucumbios province, and in the Sucumbios provinces with M. atahualpa   , M. penai   and M shushufindi   n. sp.
