Etymology. The specific name is a noun in apposition taken from the type locality Otongachi Natural Reserve.

Diagnosis. Males most resemble M. lasdamas   n. sp., but can be distinguished by their much larger size (4.41 vs. 2.69); prolateral process of leg I, P1 well sclerotized and triangular ( Fig. 23 C View FIGURES 23 ) whilst P1 inconspicuous in M. lasdamas   n. sp. ( Fig. 23B View FIGURES 23 ).

Leg spination: I: d1-1-1; tibiae v1-1, p1; metatarsus v1; II: femur d1-1-1-1; patella v2; tibia v1-1-1ap, p1; metatarsus v1-1, p1; III: femur d1-1-1; patella d1, r1-1; tibia d1-2, v2-1-1, p2-2, r2-2; metatarsus d1-1-2, v1-2ap, p1, r1-1; IV: femur d1-1-1; patella d1, p1; tibia d1-1-1, v1-1-1-2ap, p1-1-1, r1-1-1, metatarsus d1, v1-1-1, p1-1-1, r1-1-1. Tibia I: P1 triangular; P2 with an apical strong spine; P3 with two apical spines ( Fig. 23C View FIGURES 23 ). Metatarsus I with large rounded basal spine ( Fig. 23C View FIGURES 23 ). Palp: palpal tibia 2x size of cymbium, 4x longer than wide ( Fig. 19A, B View FIGURES 19 ); cymbium 2x longer than wide, with four apical spines; palpal bulb elongated-oval, embolus short, sinuous, bent apically ( Fig. 19C View FIGURES 19 ).

Female: unknown.
