Diagnosis. Males of this new species are distinguished from those of the closely related M. fasciata comb. nov. by the smaller meso-prolateral fold on the TA ( Figs 634–637 View FIGURES 634–640. 634–637 ), and by the somatic morphology in which the opisthosoma lacks a distinctive pattern but is clothed with numerous elongated bristles instead (Gigs 604–605). Females can be distinguished from those of M. fasciata comb. nov. by the more pronounced epigynal plate, with elevated triangular posterior median hump ( Figs 618 View FIGURES 615–624. 615 cf. 616); the spermathecae are stouter and more truncated ( Figs 628 View FIGURES 625–633. 625 cf. 625).

Etymology. The specific epithet is a latinized combination of the words αλλOς (= another) and rostratus (= with a beak), emphasizing the rostrate TA of the male palp.
