Marliella Mews & Mól gen. nov. et sp. nov.
Type species: Marliella titai Mews & Mól sp. nov.
Etymology. The genus name is in honor to Marli Marta Mews.
Diagnosis. Head with three ocelli, forming an equilateral triangle. Male forewing reduced (Fig. 1 B); forewing without glandular hair, stridulatory vein and glandular border. 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 A); pseudepiphallic paramere 2 cut (Fig. 6 A), teethed ventrally (Fig. 6 B); pseudepiphallic paramere 1 in “L” shaped, with small denticles on the internal side; female copulatory papilla sclerotized, conical shaped (Fig. 7 A-C).
Marliella titai Mews & Mól sp. nov. (Figs.1 B, 6 and 7)
Etymology. The specific name is in honor to the biologist Cândida Lahís Mews, nickname “Tita”, that collected this species for the first time.
