(Figs 8–10)
Etymology. The specific epithet refers to the coloration pattern of the legs, which consists of alternating lines of light and dark brownish areas, similar to the colour pattern of a tiger.
Diagnosis. This species can be distinguished from the others species of Rumea by the following combination of characters: (i) body coloration darker than that of R. zebra sp. nov. and R. manauensis sp. nov.; (ii) face without striped coloration pattern; (iii) eyes dark brownish and more ventrally elongated than those of R. zebra sp. nov. and R. manauensis sp. nov., each eye bearing a whitish oval area at the dorsal inner surface that is smaller than those of R. zebra sp. nov. and R. manauensis sp. nov.; (iv) anterior and posterior pronotum edges broadly rounded, giving a suboval appearance to the pronotal surface when seem from above; male genitalia with (v) dorsal tip of the pseudepiphallic arm with a rounded small lobe on the midline, (vi) lateral lobes of the pseudepiphallic bridge with two projections, one being reduced and barely visible from above, (vii) lateral lobes of the pseudepiphallic arm curved ventrad-outwards, ventrad pronounced as seen in lateral view, (viii) ectophallic apodemes slightly curved inwards.
Description (holotype male; female unknown). Holotype male: TL 20.03; HF 15.28; HT 12.66; sHT, inner margin 25–30, outer 22–25; sHts, inner margin 6–8, outer 8–9; PL 3.43; PW 4.22; EyeW 1.84; TegL 16.05; TegW 7.04; SL 4.35; NT 124. General coloration consisting of dark brownish and dark yellowish areas (Fig. 8). Head bearing robust bristles at the vertex (Fig. 9 A). Face with coloration dark brownish with small light brownish areas, without of striped pattern. Frons bearing an indistinct light yellowish oval mark on the longitudinal midline at eye level; two semi-rounded light yellowish oval areas at eye level, close to the antennal socket; two oblique light yellow stripes at the middle of each gena; a light yellow undefined area above the subgenal suture. Clypeus greyish, with two distinct dark brownish marks at each side of the longitudinal midline, and a triangle-shaped mark at the midline. Labrum greyish with two darker lateral stripes, none of them reaching the ventral margin. Mandibles dark yellowish with a large dark brownish mark, cutting edge dark brownish. Maxillary palps light brownish. Last palpomere of each maxillary palp dark brownish. Labial palps whitish; second labial palpomere with several distinctive yellowish spots at the base, and light greyish spots at the ventral side. Mouthparts in ventral view, excepting the appendages, light yellowish. Antennal scape dark yellowish with small black spots at the tip and an oblique dark brownish line from the tip to the ventral margin; antennomeres dark yellowish. Head dorsal surface (Fig. 9 B) with four brown longitudinal stripes: two stripes originating at the posterior margin and jointed at the eyes level, so that only one thick stripe reaches the anterior margin; two lateral stripes, one at each side, originating at the posterior margin and ending at the ventral margin of each eye. Additionally, there is one stripe, originating at the base of each lateral stripe, which is bifurcated forming one stripe that reaches the inner margin of the eye and another faint stripe extending to the anterior ventral surface but disappearing, not reaching the face. Eyes dark brownish, each with a whitish oval area at the dorsal inner surface; central ocellus oval, almost three times bigger than the two other ocelli, the latter been almost indiscernible. Thorax with the pronotal margins broadly rounded (Fig. 9 C), giving a semicircular appearance to the pronotum when seen from above. Anterior and lateral margins bearing robust bristles; lateral surface dark brownish. Pronotum with disc dark yellowish and bearing dark brownish areas; anterior margin with dark brownish border along it, the border bearing a small subtriangular mark at the longitudinal midline; a distinctive triangular mark on each side of the midline, with one outer mark being dark brownish and the inner mark dark yellowish; posterior margin with two indistinct oval marks parallel to it, one mark at each side of the longitudinal midline; two ovals dark yellowish marks at the midline, one close to the posterior margin and the other above it; posterior portion with a light yellowish border along the margin. Tegmina translucent, brownish; right tegmen (Fig. 9 D) with mirror bearing eight curved veins; harp with five veins. Hindwings (Fig. 9 E) translucent, brownish. Sternum light yellowish. Metasternum darker than sternum. Fore- and midlegs (Fig. 9 F) as follows: each coxa and trochanter yellowish with indistinct dark spots like shadows; femur light yellowish, with two conspicuous brownish rings, one near the apex and the other below it, being separated from each other by a yellowish space, the rings being incomplete at the lower surface; tibia with two brownish dark areas, one at the tip and the other at the middle. Hindlegs with femur (Fig. 9 G) bearing four conspicuous brownish rings intercalated with yellowish stripes; hindtibia light brownish, with a dark brownish mark at the upper surface near the apex. Tarsomeres of fore- and midlegs light brownish, darker than the tarsomeres of the hindlegs. Tarsus claws of all legs whitish with black tips. Abdomen with the tergites and sternites dark yellowish, each with some irregular dark spots like shadows. Cerci dark yellowish. Posterior margin of the supra-anal plate broadly rounded (Fig. 9 H), dark brownish with a light yellowish mark at the midline. Subgenital plate (Fig. 9 G) light brownish at the anterior portion, with a dark brownish rounded mark near either posterior-lateral side; posterior area dark brownish; posterior margin with an emargination at middle and two feeble lateral lobes. Male genitalia (Fig.
10) with the dorsal tip of the pseudepiphallic arm bearing a small rounded lobe on the midline, that is visible in lateral view (Fig. 7 B); pseudepiphallic lateral lobes curved ventrad-outwards (Fig. 10 A and 10C), ventrad projecting in lateral view (Fig. 10 B); lateral lobe with two projections, the dorsal one reduced, similar to a small lobe, being barely visible in dorsal view (Fig. 10 A); each median lobe with a small projection (Fig. 10 B); ectophallic apodemes directed outward (Fig. 10 A); each ramus not reduced, bearing two undulations.
