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

Diagnosis. Males resemble those of M. ramirezi n. sp. in having the dorsal abdomen with unremarkable pattern of very fine lines, almost unnoticeable, forming four or five chevrons along a longitudinal line, but in M. tabay n. sp. this longitudinal line reaches the pedicel (Fig. 20 A). Can be further distinguished by their longer embolus (over three times the greatest diameter of the bulb) (Figs 19 G, 20D–E).

Chelicerae, palps and legs orange; coxae and trochanters orange. Endites light orange, labium and sternum orange. Abdomen dark gray with unremarkable pattern of very fine lines, almost unnoticeable forming four or five chevron along a long longitudinal line, that reaching the pedicel (Fig. 20 A). Anal tubercle and spinnerets lighter than abdomen. Crista short, gladius with the common shape among nopine. Palp with a spherical oval bulb, embolus longer than cymbium (Figs 19 G, 20D–E), tip of embolus slightly curved, stout, with truncate opening and a pointed projection (Figs 19 J–K).
