Types. Male holotype and female paratype from Casa Cesar Tapia, Cotopaxi Province, Ecuador, 13.ix.2013, sifting litter, E. Tapia & N. Dupérré, deposited in QCAZ, not examined.

Material examined. Ecuador: Pichincha: 47 km. S of Santo Domingo, Rio Palenque , (0°44'S 79°48'W), 26– 30.v.1975, S. Peck, 1♂ ( AMNH) GoogleMaps . Santo Domingo de los Tsáchilas: Las Damas (0°11'23"S 78°53'59"W), 1209 m asl., 12–23.vii.2014, N. Dupérré and E. Tapia, pitfall trap, 1♂ (left palp for SEM), 1♀ (genitalia for SEM) ( QCAZ) GoogleMaps .

Diagnosis. Males and females resemble those of M. blades n. sp. and M. murici n. sp. in having the abdomen with a light whitish gray dorsal chevron pattern, but can be distinguished by having the proximal chevron mark thin and bigger than the others, without the longitudinal line directed to the pedicel ( Fig. 8 View FIGURE 8 A). Males have a small bulb, the greatest width of bulb fits three times on the cymbium length ( Figs 7 View FIGURE 7 A; 8D–E), embolus shorter than cymbium length, tip of embolus curved, stout ( Figs 7 View FIGURE 7 D–E); and females with a deep median concavity (mc) on distal margin of receptaculum (dmr), without median septum or invagination ( Figs 7 View FIGURE 7 G–I).

Description. Male and female described in detail by Dupérré (2014). Additionally: Male and female with short crista, gladius with the common shape among nopine. Female external genitalia with transversal and wide genital opening (go) and wide sclerotization around spiracles, genital opening and posterior plate ( Fig. 8 View FIGURE 8 C). Internal genitalia with strongly concave distal margin of receptaculum; proximal section of uterus externus (ue) wide, almost the same length of receptaculum; internal fold projected ( Figs 7 View FIGURE 7 G–I).

Distribution. Known from Pichincha, Santo Domingo de los Tsáchilas and Cotopaxi provinces in Ecuador ( Fig. 21 View FIGURE 21 ).
