Type.
Neotype: male, designated herein. Cabezza de Lagartos , Tumbes, Peru. [= fig. 63 of Lent and Wygodzinsky (1979)] .
Locality data: Cabezza de Lagartos, Tumbes, Peru [no date or collector attributes given].
Depository: American Museum of Natural History, specimen number AMNH_IZC 00319810.
DNA: neotype mitochondrial genome (GenBank MT757852 View Materials ) ; neotype nuclear ribosomal second internal spacer region (ITS2) (GenBank MT362613 View Materials ) .
Diagnosis.
The neotype can be immediately distinguished from the other observed T. dimidiata s.l. specimens by the following combination of character: pronotum with anterior lobe presenting 1+1 discal tubercles (one on each side of anterior lobe), pointed posteriorly, and 1+1 round, smaller lateral tubercles. Legs uniformly dark brown, one pair of subapical denticles on fore and middle femora; femur and tarsi setose with setae same color as tegument. Spongy fossula observed on fore- and mid-legs.
Description.
Measurements: Table 1 View Table 1 . Coloration: generally brown, with connexivum and wings yellow. Head brown with setosity lighter than the tegument. Labium with first visible segment dark brown and second visible segment slightly paler than first. Neck brown, with 1+1 dark-yellow stripe. Pronotum brown, anterior lobe slightly darker than posterior lobe. Collar brown with anterolateral angles yellowish apically (Fig. 2A, B View Figure 2 ). Hemelytra with corium and most part of the clavus yellow and membrane smoky-brown. Basal portion of clavus brown, subcostal vein almost all yellow, except apex which bears a brown claw-shaped spot. Small dark oval spots adjacent (above, but not over) m-cu cross vein. Legs uniformly dark with femora and tarsi setosity with same color as tegument. Connexivum in dorsal view mostly yellow, with brown spots on first third of each segment adjacent to sutures (Fig. 2A View Figure 2 ). In ventral view, abdomen mostly brown on the center, with unique continuous yellow band separating the connexival segments and the center (brown) of the sternites (Fig. 2B View Figure 2 ).
Structure: head shallowly rugose on dorsal view, less than twice as long as width across the eyes (1: 0.62), and slightly shorter than the pronotum (1:1.1). Anteocular region about twice as long as the postocular region (1:0.48) (Fig. 5A View Figure 5 ). Eyes surpassing the ventral but not the dorsal margin of the head (Fig. 5B View Figure 5 ), in lateral view. Ratio of the width of eye to synthlipsis: 1:1.21. Ocelli larger than the distance from the eyes to ocelli (1:0.4) and inserted on conspicuous C-shaped protuberance (Fig. 5A View Figure 5 ).
Antenniferous tubercles subcylindrical, situated slightly after the posterior half of the anteocular region (Fig. 5A View Figure 5 ). First antennal segment not attaining to level of apex of clypeus; other antennal segments missing (Fig. 5A View Figure 5 ). Labium slender, with first visible segment not reaching the level of the base of antenniferous tubercle; second visible segment extending to neck; third visible segment reaching the anterior third of stridulatory sulcus (Fig. 5B View Figure 5 ). Ratio of visible labium segments: 1:1.8:0.9.
Pronotum with anterior lobe presenting a distinct depression and with 1+1 discal tubercle, pointed posteriorly, and 1+1 round, smaller lateral tubercles (Fig. 6 View Figure 6 ). Anterolateral angles presenting almost triangular, anterolaterally directed. Posterior lobe slightly rugose. Humeral angles slightly elevated and rounded. Scutellum rugose; posterior process of scutellum with rounded apex, shorter than basal portion of scutellum (Fig. 7 View Figure 7 ).
Hemelytra not reaching the posterior margin of VII urotergite (Fig. 2A View Figure 2 ). Legs with one pair of subapical denticles on fore and mid femora (Fig. 8 View Figure 8 ); spongy fossae on the apices of fore- and mid-tibiae.
Abdomen ventrally convex, delicately striate transversally. Width of abdomen 0.39 times the total body length (1:0.39). Abdominal spiracles adjacent to connexival suture, surrounded by a round brown spot.
