Material. Holotype male: Brazil: São Paulo State: Peruíbe ( Estação Ecológica Juréia-Itatins — 24º22'48"S, 47º04'40"W — 10 m —NC 1799), 09-III-2000, leg. F. A. A. Lencioni — Paratypes: 3 ♂ same data as holotype ( NC 1797 , 1798 , 1800 ) . Holotype and two paratypes deposited in the author’s collection. One paratype deposited at INPA .

Etymology. I name this species after Freddie Mercury, artistic name of Farrokh Bulsara (1946–1991), superb and gifted musician and songwriter whose wonderful voice and talent still entertain millions of people around the world.

MALE (Holotype). Head: labium pale; labrum dark brown with proximal border orange; base of mandibles and genae brown; anteclypeus brown with central yellow transverse line; postclypeus black; antefrons brown with central black spot; postfrons and epicranium matte black with two pale lines, each extending from lateral ocellus to base of respective antennae (Fig. 38A). Prothorax: propleuron pale orange; median lobe dark brown; posterior lobe matte black. Pterothorax: mesepisternum dark orange with matte black spot on posterior 1/5 meeting antealar crest; antealar carina matte black; mesepimeron and ventral 3/4 of mesinfraepisternum black; metepisternum orange; metepimeron pale orange (Figs. 38A–B); legs pale brown; wings slightly flavescent. Abdomen: S1 black above, orange below; S2 black above with long triangular middorsal pale mark, orange below; S3–6 dark brown above with very narrow middorsal carina yellow, dark color expanding laterally after pale basal ring and at distal end; S7 black except for pale basal ring; S8 anterior 1/2 dark brown above and laterally, posterior 1/2 orange; S9– 10 and cerci orange ( Fig. 58A ).

Cercus in lateral view: dorsobasal expansion present. Ventrobasal expansion very large, occupying almost 2/3 of the length. Ventral margin almost straight (Fig. 26B).

Cercus in mediodorsal view: basal portion subequal to medial, apical portion longest. Ventral expansion present and sparsely hairy. Ventral branch of medial process triangular plate with apex truncated, ridge dividing it in two parts, dorsal branch roughly triangular and fused with the ridge at 2/3 from the base, inner edge strongly sclerotized (Fig. 26A).

Measurements (mm). Total length 55.5, abdomen 45.5, forewing 31, hindwing 30.

Female unknown.

Variation in paratypes. Same color as holotype but total length 52–53, abdomen 42–43, forewing 30–31, hindwing 29.5–31.

Illustration made from following specimens. 1♂ —(Fig. 26A, 26B, 38A, 38B, 38C, 58A)— Brazil: São Paulo State: Peruíbe ( Estação Ecológica Juréia-Itatins ), 09-III-2000, leg. FAAL (Holotype —NC 1799) .
