5 to about 30, see text [1] Aveexcrenota Salazar & K.Johnson, 1997 Denivia K.Johnson, 1992 Lucilda D'Abrera & Bálint, 2001 (may be nomen nudum) Margaritheclus Bálint, 2002 (but see text) Theritas is a genus of gossamer-winged butterflies (family Lycaenidae) found in the Neotropics.

They typically have a pennant-like hindwing "tail" which projects outwards at an approximate right angle from the squared-off edge of the tapered tornal area.

But these traits – as opposed to the androconia pouches discussed below – are also found in several other Eumaeini, which have been included in this genus but do not really appear to belong here.

This genus has some sexual dichromatism in that the males show green iridescence of the blue upperwing color.

T. drucei and T. triquetra as well as some species of the disputed assemblage are known from Santa Catarina or its surroundings, while the rest of the paupera group but also many other related Lycaenidae are found in the Andes.
