description: Bebaiotes wilsoni sp. nov.   
 (Figs 34A – E; 35A – G; 36A – E; 38F; 41G, H; 44)   
 Type material. Holotype male (INPA). BRASIL, Amazonas, Manaus, Km 41, PDBFF, 21.v.1986, Malaise, R. C.S. 1, Res [eserva] 1301, B. Klein col.   
 Condition of the holotype: Hind wings damaged on apical half.   
 Paratypes. Amazonas, Manaus, Km 41, PDBFF, 11.xii.1985, Malaise, R. C.S. 1, Res [eserva] 1301, B. Klein col. (1♀, INPA); Manaus, Km 41, PDBFF, 16–18.iii.2005, Malaise, sub-bosque, R. Querino col. (1 ♂, INPA); Manaus, Embrapa, Guaraná orgânico, 2˚53’42,18”S/59˚58’45,80”O, 01.ii.2013, Malaise, Ponto Mata, K. Schoeninger leg. (1 ♂ INPA).   
 Diagnosis. Body coloration brown (Figs 34A, B). Anterior margin of pronotum with rounded apex (Fig. 34D). Forewing with wide, brown transverse band on apical region extending from apex of the RP vein up to icua cross-vein (Fig. 41G). Ventral margin of periandrium with short indentation (Fig. 35G).   
 Description. Measurements. Body length: male 2.6 – 2.7 mm (5.5 – 5.8 mm including wings) (N=2); female: 3.2 mm (5.8 mm including wings).   
 Coloration. General body color brown (Figs 34A, B). Pedicel plaque organs white. Forewing semihyaline, light brown, long, wide, brown transverse band on apical region extending from apex of the RP vein to icua cross-vein; small brown rounded spot on median region of the postclaval cell (Fig. 41G). Hind wing semihyaline, light brown with hyaline regions (Fig. 41H). Legs yellow brown. Abdomen dark brown, except sternites III, VII, anal tube (segment X), pygofer and gonostyli light brown.   
 Head: frons narrowed, distance between the lateral carinae of frons on median portion, approximately 3 times smaller than maximum width of vertex (Fig. 34C). Clypeus approximately 2.5 times longer than its maximum width; median carina of clypeus strongly marked, does not touch epistomal suture, present on distal ¾ (Fig. 34C). Pedicel oblong, approximately 2.5 times longer than scape (Fig. 38F). Scape long without cuticular denticles (Fig. 38F).   
 Thorax: anterior margin of pronotum with rounded apex, lateral longitudinal carinae gently diverging towards posterior margin; median longitudinal carina of pronotum present, but weakly marked; posterior margin of pronotum concave with shallow median notch in the middle; pronotum without pustules on posterior margin (Fig. 34D); median and lateral longitudinal carinae of mesonotum present, but weakly marked (Fig. 34D).   
 Forewing: RA and RP veins with the apex not curved; r-m cross-vein present; ir cross-vein distant from rm 1cross-vein, not aligned; MP vein with four branches with apex gently curved posteriorly; first bifurcation of MP vein arising before r-m cross-vein; m-cu cross-vein present; CuP vein approximately 3 times longer than Pcu + A1 vein; apex of clavus with straight angle (Fig. 41G).   
 Hind wing: first bifurcation of MP vein arising before m-cu cross-vein (Fig. 41H).   
 Legs: metatibia with 8 apical spines; metatarsus with 7+6 apical spines.   
 Abdomen: posterior half of sternites IV + V and VI with four long, thin, whitish setae; posterior margin of sternites VII semi-rounded. Female (Fig. 34B). Similar to male.   
 Male terminalia (Figs 35A–G). Pygofer with posterior margin without projections, with a few sparse setae in posterior view (Fig. 35B). Gonostyli with truncated apex in lateral view, outer margin with short projection and with a rounded apex near apex and surface and inner margin with some setae (Figs 35A, D, E). Phallic complex (Figs 35F, G): periandrium semi-oval in dorsal view, dorsal margin flap-shaped, without indentation at the apex and ventral margin with short indentation at the apex (Figs 35F, G). Inner sclerotised plates narrowing towards the apex, with serrated inner margin and surface with small spiniform projections in the base (Figs 35F, G). Anal tube (segment X), short, apex smoothly reentrant in dorsal view, with few sparse setae dorsally (Fig. 35C).   
 Female terminalia (Figs 36A–E). Pygofer with a few setae and numerous small spiniform projections in posterior view (Fig. 36B). Gonapophysis VIII (first valvula) robust, with sparse setae on median region and covered with small spiniform projections in all its extension in lateral view; three lateroapical projections of unequal sizes, one projection finger-like and two with smooth dorsal margin in lateral view (Fig. 36E). Bursa copulatrix sparsely filamentous apically, acute apex, with a few setae laterally near to apex and small spiniform projections on apical half in lateral view (Fig. 36E). Gonapophysis IX (second valvula) slender, forked at ⅓ apical, lobes with a pointed apex, strongly curved latero-ventrally in dorsal view (Fig. 36D). Gonoplac (third valvula) subtrapezoidal, apex semi-rounded with several setae apically, sparse setae laterally and a few small spiniform projections in the basal half in lateral view (Fig. 36C). Anal tube (segment X), short, apex smoothly reentrant, with sparse setae in dorsal view (Fig. 36A).   
 Variations. Variations in the coloration of prothoracic, from light brown to dark brown, and red diffuse spots on the abdomen, have been observed in some specimens.   
 Etymology. The species is named in honor of Dr. Michael R. Wilson from the National Museum Wales, for his immense contribution to the knowledge of Achilixiidae.   
 Distribution. Brazil (Amazonas) (Fig. 44).   
 Comments. B. wilsoni sp. nov. differs from B. bia sp. nov. as previously discussed in the description of the latter.
