Tetralidia Marques-Costa & Cavichioli

Diagnosis. Crown approximately quadrangular, with two pairs of orange maculae, one close to anterior margin and another close to posterior margin, adjacent to compound eyes ( Fig. 1 ); transverse carina present at transition between crown and frons ( Figs 2, 3 ); ocelli on anterior margin of head, at transition between crown and frons ( Fig. 3 ); clypeus with lateral margins convergent apically ( Fig. 2 ); posterior margin of pronotum emarginated and Vshaped ( Fig. 1 ); forewings with venation indistinct or slightly distinct with four apical cells and three anteapical cells ( Fig. 4 ); hindwings with R4+5 and M1+2 preapically convergent, fused at apex, forming single vein. Male genitalia. Pygofer without processes or teeth ( Fig. 5 ); connective variable, bifurcated or not at articulation point with aedeagus ( Fig. 8 ); aedeagus long with pair(s) of apical or preapical process(es) or lamellae ( Figs 9, 10 ); anal tube with pair of variable basal processes ( Fig. 5 ) Marques-Costa & Cavichioli (2008); subgenital plates narrowed basally or pre-apically, separated only in most distal portion of apex ( Fig. 6 ) and style with truncated apex ( Figs 7, 8 ).

Tetralidia closely resembles Tozzita Kramer, 1964 in having the clypeus with lateral margins convergent apically; the pygofer without processes; the aedeagus long and the anal tube with a pair of basal processes. It differs from Tozzita by the absence of a black spot at the apex of the crown; the ocelli on the transition between crown and frons (in Tozzita located on the crown, near the anterior margin) and the pygofer with a rounded apex (flattened and spatulate in Tozzoita) Marques-Costa (2008).
