DIAGNOSIS. — This species is separated from the other species of Tafalisca by the following characters: General coloration reddishbrown, antennomeres light to medium yellow; metanotum without projections; dorsal field with reticulated veins between parallel veins; TI and TII with a small, rounded and unpigmented protuberance on apical region of dorsal face, this region without bristles. Male genitalia: MLophi not surpassing LLophi of pseudepiphallus apex in dorsal view, curved outwards in dorsal view; LLophi apex curved inwards forming an angle less than 90°; basis of PsP twisted.
Body. Medium to large size; general coloration reddish-brown; body almost entirely covered by small yellowish bristles, except FWs and hindwings.
Head. Occiput and vertex covered by small bristles, reddishbrown, almost uniform ( Fig. 11A, C View FIG ). Frons pubescent, light brown ( Figs 11A, C View FIG ; 4A, C View FIG ); fastigium longer than wide, covered by small bristles, lighter than vertex ( Fig. 11A, C View FIG ). Three ocelli, the median elliptical, very reduced, smaller than lateral ones; lateral ocelli rounded ( Figs 11B, C View FIG ; 4B, C View FIG ). Antennal scape longer than wide in frontal view, few bristles on the inner face in frontal view, yellowish; pedicel same color as the scape; antennomeres light to medium yellow ( Fig. 11C View FIG ). Gena pale light brown in frontal and lateral views. Mandibles light brown, apex dark brown almost black ( Fig. 11C View FIG ). Clypeus light brown, whitish laterally; labrum whitish ( Fig. 11C View FIG ). Maxillary palpi pubescent, articles 3-5 elongated almost same-sized; article 3 light brown, articles 4 and 5 medium to dark brown; apex of article 5 unpigmented ( Fig. 11B, C View FIG ).
Pronotum. DD wider than long, pubescent, reddish-brown; with two median elliptical maculae yellowish (one specimen medium brown); caudal margin medium to dark brown. DD cephalic margin slightly concave, and caudal margin slightly convex; LL ventro-cephalic angle rounded, ventrocaudal angle gradually ascendant ( Fig. 11A, B, J View FIG ).
Legs. Legs I and II pubescent, with a small, rounded and unpigmented protuberance on apical region of dorsal face of TI and TII, this region without bristles (arrows on Fig. 11E View FIG ). FI and FII yellow-brown to light brown; TI and TII reddish brown. TI with two ventral apical spurs same-sized, one dorsal spur smaller, tympana absent. TII with two ventral spurs same-sized and two dorsal spurs, inner spur smaller or absent. FIII slightly pubescent, reddish-brown, darker apically; TIII dark brown ( Fig. 11E, F View FIG ).TIII subapical spurs 5/4 with a spine between them, two spines above the first subapical spur; apical spurs 3/3, longer on inner face; inner spurs: dorsal longest (iad), median slightly shorter (iam), ventral smaller (iav) (iad>iam>iav) ( Fig. 11F, G View FIG ); outer apical spurs: median longest (oam), dorsal slightly shorter (oad), ventral smaller (oav) (oam>oad>oav) ( Fig. 11F, G View FIG ). Basitarsus dark brown, with three outer spines in line, apical longest, one inner apical spine.
Abdomen. Tergites slightly pubescent, light brown, without longitudinal band. Sternites yellowish brown. Cerci pilose, light brown; with dark brown setae. Supra anal plate pubescent, medium to dark brown; posterior margin rounded ( Fig. 11H, K View FIG ).
Metanotum without projections, antero-lateral regions inflated, medio-posterior region somewhat elevated, lighter than pronotum DD ( Fig. 11D View FIG ). FWs long, covering entire abdomen, medium brown, slightly translucid; left and right FWs with same color and texture; FW dorsal field without stridulatory apparatus; eight longitudinal and parallel veins light yellow; reticulated veins between parallel veins; lateral field with ten diagonal and parallel veins light yellow; ( Fig. 11A, B View FIG ). Hindwing apex surpassing FW apex. Subgenital plate pubescent, anterior margin concave, posterior margin rounded, yellowish-brown ( Fig. 11I View FIG ).
Male genitalia ( Figs 12 View FIG A-C; 13)
Pseudepiphallus: pseudepiphallic sclerite upcurved in lateral view, divided into two lobes: MLophi and LLophi. MLophi thin, bilobate, curved outwards, somewhat short, not surpassing LLophi in dorsal view; LLophi thin, elongated, curved inwards in dorsal view; apex curved inwards forming an angle less than 90°; MLophi and LLophi sharing a membrane between them. PsP as long as pseudepiphallic sclerite, curved inwards in ventral view, upcurved in lateral view; distal 2/3 thin, proximal 1/3 larger; proximal apex twisted; R short connected to pseudepiphallic sclerite by membranes.
