PARATYPES: 1 ♂ ( UCR), Same data as holotype; 1 ♂ ( UCR), Same data as holotype except 23.XI.2018; 4 ♂ 3 ♀ ( UFPA), same data except Trilha da [= trail of] Mariana / 01º25’24.92”S 48º26’20.91”W / 14.IX.2018GoogleMaps  ; 3 ♂ 1 ♀ ( MPEG), same data as before except 08.X.2018GoogleMaps  ; 2 ♂ 1 ♀ ( MPEG), Melgaço-Pará-Brasil [municipality of Melgaço, state of Pará, Brazil] / Estação Científica [= Scientific Station] Ferreira Penna / FLONA [= National Forest] Caxi- uanã / 01º44’18.02”S 51º27’48.01”W / 09–14.XI.2005 / Col [= collector]: Barreiros, J. A. P. / Pitfall.GoogleMaps 

Measurements: Males. Total length: 1.10–1.52 mm; antennal segments: I: 0.06–0.09 mm; II: 0.06–0.08 mm; III: 0.4 mm; IV: 0.4 mm; width between eyes: 0.30–0.32 mm; pronotum length: 0.21–0.37 mm; pronotum width: 0.56–0.65 mm; scutellum length: 0.14–0.26 mm; abdominal width: 0.42–0.68 mm.

Females. Total length: 1.22–1.28 mm; antennal segments: I: 0.06–0.09 mm; II: 0.07–0.08 mm; III and IV: unknown; width between eyes: 0.30–0.32 mm; pronotum length: 0.18–0.21 mm; pronotum width: 0.54–0.55 mm; scutellum length: 0.16–0.21 mm; abdominal width: 0.64–0.67 mm.

Diagnosis. Process of mediotergite 7 short, curved; apex slightly curved laterally ( Fig. 5AView FIGURE 5), but sometimes resembling a tiny notch ( Fig. 5BView FIGURE 5). Process of mediotergite 8 (mt8p) small, spiniform ( Fig. 5AView FIGURE 5). Anophoric process thick, long and tapering distally, with distal portion strongly curved laterally ( Fig. 5A; 5EView FIGURE 5). Right paramere curved, very long, almost as long as pygophore, thin with widened apex bearing two small claw-like projections ( Fig. 5A; 5DView FIGURE 5).

Description. Male ( Fig. 2View FIGURE 2 A–C). The same description of H. bifidus  except for abdomen: Mediotergite 8 smaller and narrower, but almost as long as mediotergite 7 ( Fig. 5AView FIGURE 5).

Female Brachypterous ( Fig. 2View FIGURE 2 D–F), similar to the male in size and color. Head without ocelli. Forewings elytroid, uniformly dark brown. Tarsal formula 2-2-3. Abdominal segments symmetric.

Abdomen ( Figs 6View FIGURE 6 A–C; 7D–F). Abdominal tergites without setae, except tergite 8 that bears a median cluster of setae on posterior half and three setae around spiracle. Tergite 7 with median dorsal abdominal gland scars on the posterior margin. Tergite 9 covered with setae and almost triangular, with a medial membranous anal tube. Base of anal tube with a contiguous pigmented structure, subquadrangular, with the same width of the anal tube. Sternites covered with setae; sternites 1 to 6 wider than long, sternite 7 almost as wide as long. Sternite 7 with a pair of small rounded projections on posterior margin (posterior projection of sternite). Gonapophyses 8 elongate and filiform, gradually tapering toward apex, widely separated at base. Gonapophyses 9 thin, short, and straight. Gonapophyses 8 and 9 not interlocking. Spermathecal reservoir elongate, segmented, and U-shaped; spermathecal duct long and coiled; spermathecal gland small and rounded; spermathecal gland duct straight and narrowed.

Etymology. Named for the remarkable anophoric process that is more robust than in the other species of Hoplonannus  .

Distribution. Brazil (Pará).
