Niborskiana notabilis (Drake) n. comb.

( Figs. 2 , 7–10 )

Tigava notabilis Drake, 1922: 364 ; 1930: 1; Monte, 1944: 159 ; Drake & Ruhoff, 1965: 389.

Diagnosis. End of posterior process blunt ( Fig. 7 ); punctures of posterior process larger than pronotal punctures; discoidal area between 5.5 and 6 times longer than wide; hemelytra approximately 4 times longer than wide.

Redescription ( Fig. 2 ). General colour yellowish brown. Head ( Figs. 7, 8 ) ashy brown; cephalic spines yellow, blunt; clypeus dark brown; bucculae yellowish with several small areolae. Rostrum yellow except for the brown apex. Antennae same length as body; scape, pedicel and basiflagellomere reddish brown, distiflagellomere black except for yellowish base. Scape more than twice the length of the head (between 2.25 and 2.75), glabrous; pedicel glabrous; basiflagellomere with scattered, semierect setae; distiflagellomere filiform, approximately same length as scape, with abundant, long setae.

Pronotum ( Fig. 7 ) reddish brown, coarsely pitted; collar yellowish with three rows of areolae; callus ashy red, glabrous; lateral carinae low, same height throughout length; punctures of posterior process becoming gradually larger posteriorly, except for the last one that is much larger than the rest; apex of posterior process blunt. Thoracic sterna reddish brown; rostral laminae as in Figure 9 .

Hemelytra ( Fig. 10 ) yellowish, with a mediolongitudinal dark area extending to the apex of the sutural area enclosing an area wherein the vein as well as the cells are paler; discoidal area dark brown except for distal apex, between 5.5 times and 6 times longer than wide, three rows of areolae at its maximum width.

Measurements. Females (N= two) and male (N= one) respectively.: Body length: 5.20–5.10 4.90; Scape: 0.90–?–0.92, pedicel: 0.15–?–0.15, basiflagellomere: 1.42–?–1.47, distiflagellomere: 0.87–?–0.95; Antennal proportions: 0.27–?–0.26: 0.040–?–0.040: 0.42–?–0.42: 0.26–?–0.27; Head length: 0.45–0.42–0.42, width: 0.57– 0.55–0.55; Pronotal length: 1.82–1.75–1.65, width: 0.95–0.90–0.87; Hemelytra length: 3.75–3.75–3.55, discoidal area length: 1.60–1.65–1.55, width: 0.25–0.25–0.27.

Distribution. Bolivia and Brazil.

Host plant. Unknown.

Comments. The length of the scape is quite variable among the different specimens but is always longer than in N. gracilis . In addition to the characters mentioned in the diagnosis, N. notabilis can be easily distinguished from N. gracilis by the longer and more slender body and by the scape which, although it is quite variable among the different specimens, is always longer. When Drake (1922) described this species he mentioned that “the very narrow carina-like paranota and costal area of the elytra, each without areolae, distinguish T. notabilis at once from any other known species in the genus”. These characters, shared with N. gracilis , are actually some of the characters that define the new genus Niborskiana .
