Wide central area of postclypeus with pale yellow pubescence directed toward central region close to frons, and yellowish-white pubescence directed forward close to anteclypeus; sides with sparse pale yellow pubescence; with one long, erect dark seta on each side of wide central area. Labrum with moderately sparse, long yellowish-brown setae directed forward on posterior half, and dense fringe of yellowish-brown setae close to anterior margin. Gulamentum smooth and glabrous, except a few short, decumbent pale yellow setae close to anterior margin. Distance between upper eye lobes 0.22 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.51 times distance between outer margins of eyes.

Abdomen. Ventrites coarsely, abundantly punctate; with abundant yellow pubescence forming longitudinal band on each side of central area, pubescence sparser between these two bands, and with dense yellow pubescence laterally, pubescence sparse between lateral pubescence and central pubescent bands.

Male ( Fig. 5 ). Similar to females; differs by the antennae slightly surpassing elytral apex.

Type material. Holotype female from BOLIVIA, Santa Cruz: 4–6 km SSE Buena Vista, Flora & Fauna Hotel , 19–22.X.2004, Wappes & Morris leg. ( FSCA) . Paratypes — BOLIVIA, Santa Cruz: 5 km SSE Buena Vista , 17º29’S, 63º39’W, 440 m, Hotel Flora & Fauna, 1 female, 1.XI.2004, Robin Clark Gemuseus leg. ( MZSP) ; 1 female, 18.X.2004, Robin Clark Gemuseus leg. ( FSCA) ; 1 female, 28.X.2004, Robin Clark Gemuseus leg. ( FSCA) ; 1 male, 21.XII.2004, Robin Clark Gemuseus leg. ( FSCA) ; 4–6 km SSE Buena Vista, Hotel Fauna and Flora , 400–500 m, 17º37’S, 63º37’W, 1 specimen, 1–10.XI.2002, S.W. Lingafelter leg. ( SWLC) . All specimens formerly from ACMT, except the specimen from SWLC.

Etymology. The new species is named after the late James E. Wappes.

Remarks. Bebelis wappesi sp. nov. is similar to B. modesta ( Belon, 1903) ( Figs 6–8 ), but differs as follows: body proportionally stouter ( Fig. 1 ); prothorax proportionally wider ( Fig. 1 ); elytra with distinct longitudinal pubescent bands in addition to the white band ( Figs 1, 5 ); mesanepisternum with abundant coarse punctures ( Fig. 9 ). In B. modesta , the body is proportionally slender ( Fig. 6 ), prothorax proportionally narrower ( Fig. 6 ), elytra only with the white longitudinal pubescent band, and mesanepisternum with sparse coarse punctures ( Fig. 8 ). The new species differs from B. lignosa Thomson, 1864 ( Fig. 10 ), B. coenosa (Bates, 1866) ( Fig. 11 ), and B. occulta (Bates, 1866) ( Fig. 12 ) especially by the oblique anterior area of the central band of the elytra (including the white pubescent band and the yellowish-brown pubescent band starting on humerus) not reaching the suture (reaching the suture in these three species).
