Tympanum present in internal face of tibia I. Tibia III with four internal dorsal spurs (the first and fourth smaller than the second and third) and four external, (the first smaller than the others, that are similar). Three internal apical spurs, the first is half of the size of the others and three external apical spurs, first and third smaller than second. Metanotal gland absent. Male terminalia: with phallic glands; pseudepiphallic arms long, curved ventral-apically, fining gradually, with teeth on all extension ( Fig. 6 View FIGURE 6 A); pseudepiphallic paramere 2 cut ( Fig. 6 View FIGURE 6 A), teethed ventrally ( Fig. 6 View FIGURE 6 B); pseudepiphallic paramere 1 in “L” shaped, with small denticles on the internal side; female copulatory papilla sclerotized, conical shaped ( Fig. 7 View FIGURE 7 A-C).

Marliella titai Mews & Mól sp. nov. ( Figs.1 View FIGURE 1 B, 6 and 7)
