DIAGNOSIS. — This species is separated from the other species of Tafalisca by the following characters: antennomeres yellowish with some isolated dark brown ones. Male: FWs light brown with several dark brown, almost black, spots; TIII apical and subapical spurs and spines yellow with dark brown apex and basis; metanotum with two median projections, drop-shaped with rounded tip in dorsal view; PCu vein with c. 20 very tiny stridulatory teeth ventrally. Male genitalia: MLophi very short, posterior margin rounded; PsP inclined inwards in ventral view, posterior half larger than anterior; EndSc longer than wide, posterior margin rounded, lateral margins folded ventrally. DESCRIPTION General morphology. Body. Medium to large size, general coloration reddish-brown with black brown spots, covered by bristles. Head. Occiput and vertex covered by small bristles, reddishbrown. Fastigium as long as wide, pubescent, reddish-brown ( Fig. 5 A-C). Three ocelli, median very reduced, almost in the same line as lateral ones in frontal view; lateral ocelli rounded. Frons median region covered by yellowish bristles, reddishbrown ( Fig. 5C ). Eyes almost as long as wide in lateral view, marginal ommatids light brown, others dark brown almost black ( Fig. 5B, C ). Antennal scape longer than wide, inner margin with yellowish bristles, light reddish-brown; antennomeres yellowish with some isolated dark brown ones. Gena reddishbrown in frontal and lateral views. Mandibles medium brown, apex darker. Epistomal suture, clypeus, and labrum medium brown ( Fig. 5C ). Maxillary palpi pubescent, covered by yellowish bristles; articles reddish-brown, apex light brown; article 5 larger than other articles; articles 5, 4, and 3 almost same-sized. Pronotum. DD slightly wider than long, covered by whitish bristle, reddish-brown. DD cephalic margin slightly concave, with brownish bristles; caudal margin somewhat convex, with brownish bristles ( Fig. 5A ). LL reddish-brown; ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view ( Fig. 5B ). Wings. FWs covering the entire abdomen; covered by tiny bristles, light brown with several dark brown almost black spots, veins light to medium brown. Lateral field with dark brown veins ( Fig. 5A, B ). HWs longer than FWs in dorsal and lateral views. Legs. Legs I and II with yellowish bristles. FI and FII light reddish-brown, apical margins darker.TI and TII with small area not covered by bristles, lighter that TI on dorsal side of proximal region; inner and outer tympana absent.TI and TII dark brown. TI with three apical spurs: two ventral samesized; one dorsal, inner, longer than ventral spurs. TII with three apical spurs: two ventral, same-sized; one dorsal, inner, longer than ventral spurs. FIII longer than TIII; with yellowish bristles, light reddish-brown, darker apically ( Fig. 5E ). TIII dark brown, with yellowish bristles.TIII subapical spurs 5/4, with three spines between each inner and outer pair of successive spurs, sometimes two spines between first two spurs; seven spines above subapical spurs on both inner and outer TIII margins; apex of TIII subapical spurs slightly curved. TIII apical spurs 3/3, longer on inner side; inner apical spurs: dorsal the longest (iad), median shorter than dorsal (iam), ventral the smallest (iav) (iad>iam>iav); outer apical spurs: median longest (oam), dorsal slightly shorter (oad), ventral almost same size of dorsal (oav) (oam>oad>oav). TIII apical and subapical spurs and spines yellow with apex and basis dark brown ( Fig. 5A, B, E ). Basitarsus dorsal spines 3/1, apical spine the longest; inner apical spur almost as long as basitarsus, outer apical spur slightly shorter than inner apical spur. Basitarsus medium brown.

LLophi thinner than MLophi in ventral view, their apex curved inwards, inner margin of anterior region somewhat rounded in ventral view. MLophi very short, shorter than LLophi in dorsal view, posterior margin rounded.
