Barreiros [collector] / Winckler” [specimen with head, thorax and abdomen disarticulated; abdomen removed and cleared].

PARATYPES. 2 ♀ ♀ ( MPEG): same data as holotype except 18.VIII.2003 .

Measurements: Total length: 1.39–1.65 mm; pronotum width: 0.64–0.69 mm; pronotum length: 0.28–0.30 mm; pronotal collar length: 0.06–0.08 mm; ratio of pronotal collar length to pronotum length: 0.21–0.25; eye width: 0.81–0.88 mm; width between eyes: 0.33–0.38 mm; fore-femur depth / height: 0.11–0.14; fore-femur length: 0.54–0.58 mm; ratio of height of fore-femur to length of fore-femur: 0.19–0.25; hind tibia length: 0.81–0.90 mm; ratio of length of hind tibia to width of pronotum: 1.20–1.40.

Diagnosis. Clypeus with three macrosetae. Sternite eight of male with a cluster of spine-like setae on the right side lateroventrally ( Figs. 7–8 ). Left paramere with two unequal branches, larger branch tapering distally in dorsal view ( Fig. 10 ).

Description. Male. Surface and vestiture. Clypeus with three macrosetae (two basal, one at tip); first and second labial segments with long setae ventrally, third labial segment with pair of long setae at tip and long setae ventrally; ratio of length of hind tibia to width of pronotum 1.20. Structure. Ratio of pronotal collar length to pronotum length 0.25; ratio of height of fore-femur to length of fore-femur 0.25; tarsal formula 3–3–3. Genitalia. Mediotergite eight (mt8) wider than long, plate-like; process of mediotergite eight (mt8p) long, thin and curved. Sternite eight (S8) wider than long, covered with tiny setulae and bearing a cluster of small spine-like setae on right half ventrally ( Figs. 7–8 ). Pygophore (pyg) longer than sternite eight, almost conical in ventral view ( Fig. 7 ), covered with tiny setulae. Flap-like genitalic process (flp) striated ventrally ( Fig. 7 ). Vesica (v) thin and coiled. Left paramere (lp) elongated with two unequal branches distally, larger branch tapering distally with rounded tip in dorsal view ( Fig. 10 ) and clavate in left lateral view ( Fig. 8 ), smaller branch tongue-shaped in dorsal view ( Fig. 7 ) and conical in left lateral view ( Fig. 8 ). Right paramere (rp) elongated and twisted, with conical tip bearing small setulae ( Figs. 9–10 ).

Female. Coloration. Tergites eight and nine and sternites eight and nine light brown. Surface and vestiture. Same as male; ratio of length of hind tibia to width of pronotum 1.26–1.40. Structure. Ratio of pronotal collar length to pronotum length 0.21–0.25; ratio of height of fore-femur to length of fore-femur 0.19–0.22; tarsal formula 2–2–3; pretarsus of front and mid legs with inflated arolia; tergites eight and nine and sternites eight and nine more sclerotized than remaining tergites and sternites ( Figs. 4–6 ); mediotergite seven and eight and sternites two to eight with a spiracle in posterolateral corner ( Fig. 7 ). Genitalia. Tergites seven and eight and sternites two to eight of female with a pair of spiracles ( Fig. 11 ). Tergite nine conical in dorsal view ( Fig. 12 ). Anal tube small, with bilobed posterior margin in dorsal view ( Fig. 12 ). Gonoplacs (g) small, with posterior margin rounded ( Fig. 11 ). Anterior gonapophysis (ag) with three teeth, without serration subapically ( Figs. 11–12 ). Posterior gonapophysis (pg) with two teeth ( Fig. 11 ). Spermathecal duct (spd) long and thick, contorted ( Fig. 13 ); spermathecal reservoir (spr) globular with two bends ( Figs. 13–14 ); spermathecal gland duct (spgd) subcylindrical; spermathecal gland (spgl) large and globose ( Fig. 14 ).

Etymology: The epithet amazonica refers to the biogeographic region where this species was found.

Distribution. NEOTROPICAL—Brazil (Pará).
