Paratypes: 20♂ same data of holotype but , 2♂: 21-XI-1998 ( NC 1026 and 1027) , 11♂: 22-XI-1998 ( NC 1033 to 1043 ) , 5♂: 29-XI-1998 ( NC 1052 to 1056 ) , 1♂: 19-III-1999 ( NC 1340 ) and 1♂: 26-III-1999 ( NC 1349 ) . Holotype, allotype and 13 paratypes deposited in the author’s collection. Six paratypes deposited at INPA (2♂), RWG (2♂) and AMPC (2♂) .

Etymology. I name this species after Roger Meddows Taylor, drummer and songwriter, whose powerful sound, wonderful lyrics and raspy voice have enchanted the world for over four decades.

MALE (Holotype). Head: labium pale; labrum orange; base of mandibles, genae and anteclypeus light orange; postclypeus brown with orange mark at each corner; antefrons orange with central brown triangular spot; postfrons black; top of head dark brown except for two long and wide orange marks lateral to each lateral ocellus touching the compound eye and two orange ovoid marks over each postocular lobe ( Fig. 39A View FIGURE 39 ). Prothorax: propleuron orange; anterior lobe orange, with anterior edge black; median pronotal lobe orange with central black touching anterior and posterior lobes; posterior lobe orange with very large black ovoid mark extending through entire base. Pterothorax: mesepisternum orange; antealar carina black; mesepimeron orange with elongate black spot, ending close to antealar carina, mesinfraepisternum with small black line in middle, remainder orange; metinfraepisternum, metepisternum and metepimeron orange ( Figs. 39A–B View FIGURE 39 ); legs pale; wings slightly flavescent. Abdomen: S1–10 similar to H. freddiemercuryi . Cerci orange with apical half brown (Fig. 59A, 28A–B).

Cercus in lateral view: Dorsobasal expansion present. Ventrobasal expansion small, tip slightly curved downward (Fig. 28B).

Cercus in mediodorsal view: Basal portion shortest, medial and apical portion subequal (longest than basal). Ventral expansion present with hair only on ventral edge. Ventral branch of medial process rectangular plate, apical end bifurcate, with ridge in middle attached to dorsal branch; dorsal branch triangular forming Y with ridge, inner and outer arms of Y sclerotized (Fig. 28A).

Measurements (mm). Total length 47, abdomen 38, forewing 27, hindwing 26.

Variation in paratypes. All very close to holotype but in some older specimens small black marks at end of mesepisternum; variation in size as follows (n=10): total length 47–49.5, abdomen 39–42, forewing 28–29.5, hindwing 27–29.

Illustration made from following specimens. 1♂ (Fig. 28A, 28B, 39A, 39B, 39C)— Brazil: São Paulo State: Pindamonhangaba, Fazenda Trabiju , 26-III-1999, leg. FAAL (Holotype — in tandem with Allotype —NC 1349); male habitus (Fig. 59A) : 1♂ — Brazil: São Paulo State: Pindamonhangaba, Fazenda Trabiju , 21-XI-1998, leg. FAAL (paratype —NC 1027) .

Diagnosis. All four new species can be diagnosed using the table below.

FEMALE (Allotype). Head: labium pale; labrum orange; base of mandibles, genae and anteclypeus pale; postclypeus brown with orange mark in each corner; antefrons pale; postfrons black; top of head mostly orange yellow with following black marks: black stripe linking one eye to the other (passing over postfrons), occipital bar, almost square mark linking the three ocelli (with yellowish mark between lateral ocelli) and line from occipital bar to each eye (enlarging to semicircle when reaching eye) (Figs. 44A). Prothorax: similar to H. brianmayi but median lobe brownish (Fig. 44C). Pterothorax: mesepisternum brown with pale yellow line parallel to middorsal carina; antealar carina black; mesepimeron yellowish gray with elongate black spot starting at level of second thoracic spiracle and ending close to antealar carina; metepisternum and metepimeron yellowish; legs pale; wings slightly flavescent (Figs. 44B, 59B). Abdomen: S1–10 similar to H. brianmayi but little darker (Fig. 59B). Valves of ovipositor surpassing distal S10, ventral margin with long spines. Cerci longer than S10, with small tuft of bristles at tip.

Basal plate: dorsal edge slightly concave and longer than convex outer edge, ventral edge 1/2 length of outer edge, tip rounded ( Fig. 49D View FIGURE 49 ).

Measurements (mm). Total body length 39, abdomen 31, forewing 26.5, hindwing 26.

Illustration made from following specimens. 1♀ (Fig. 44A, 44B, 44C, 49C, 49D, 59B)— Brazil: São Paulo State, Pindamonhangaba, Fazenda Trabiju , 26-III-1999, leg. FAAL (Allotype — in tandem with Holotype —NC 1349) .
