Condition of the holotype: Hind wings damaged on apical half.

Diagnosis. Body coloration brown ( Figs 34A, B View FIGURE 34 ). Anterior margin of pronotum with rounded apex ( Fig. 34D View FIGURE 34 ). Forewing with wide, brown transverse band on apical region extending from apex of the RP vein up to icua cross-vein ( Fig. 41G View FIGURE 41 ). Ventral margin of periandrium with short indentation ( Fig. 35G View FIGURE 35 ).

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 View FIGURE 34 ). 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 View FIGURE 41 ). Hind wing semihyaline, light brown with hyaline regions ( Fig. 41H View FIGURE 41 ). 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 View FIGURE 34 ). 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 View FIGURE 34 ). Pedicel oblong, approximately 2.5 times longer than scape ( Fig. 38F View FIGURE 38 ). Scape long without cuticular denticles ( Fig. 38F View FIGURE 38 ).

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 View FIGURE 34 ); median and lateral longitudinal carinae of mesonotum present, but weakly marked ( Fig. 34D View FIGURE 34 ).

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 View FIGURE 41 ).

Hind wing: first bifurcation of MP vein arising before m-cu cross-vein ( Fig. 41H View FIGURE 41 ).

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 View FIGURE 34 ). Similar to male.

Male terminalia ( Figs 35A–G View FIGURE 35 ). Pygofer with posterior margin without projections, with a few sparse setae in posterior view ( Fig. 35B View FIGURE 35 ). 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 View FIGURE 35 ). Phallic complex ( Figs 35F, G View FIGURE 35 ): 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 View FIGURE 35 ). Inner sclerotised plates narrowing towards the apex, with serrated inner margin and surface with small spiniform projections in the base ( Figs 35F, G View FIGURE 35 ). Anal tube (segment X), short, apex smoothly reentrant in dorsal view, with few sparse setae dorsally ( Fig. 35C View FIGURE 35 ).

Female terminalia ( Figs 36A–E View FIGURE 36 ). Pygofer with a few setae and numerous small spiniform projections in posterior view ( Fig. 36B View FIGURE 36 ). 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 View FIGURE 36 ). 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 View FIGURE 36 ). Gonapophysis IX (second valvula) slender, forked at ⅓ apical, lobes with a pointed apex, strongly curved latero-ventrally in dorsal view ( Fig. 36D View FIGURE 36 ). 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 View FIGURE 36 ). Anal tube (segment X), short, apex smoothly reentrant, with sparse setae in dorsal view ( Fig. 36A View FIGURE 36 ).

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 View FIGURE 44 ).

Comments. B. wilsoni sp. nov. differs from B. bia sp. nov. as previously discussed in the description of the latter.
