Diagnosis. Adult males of H. driki sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 long and tapered, hemispheric apex, projected the lateral of acropodite ( Fig. 33A–D View FIGURE 33 ); opening of solenomere located at distal end of acropodite; solenomere without projection ( Fig. 33A, C, D View FIGURE 33 ).

Material examined. Holotype ♂, Brasil, Amazonas , Barcelos, Acampamento base a 2 km N da Missão Marari (01º12’26.4”N, 64º47’18.1”W), 1350 m a.s.l, 27.IV.2004, U. Caramaschi & H. de Niemeyer leg. ( MNRJ 12011 View Materials ). GoogleMaps

Paratype: 1 ♂, Brasil, Amazonas , São Gabriel da Cachoeira , Cachoeira do Tucano, Pico da Neblina, AM 02 , noturna, 100 m, 24.IX.2007, A. Nogueira leg. ( IBSP 2857 View Materials ) .

Description.

Size and form (holotype ♂). Body length = 66 and wide = 8 mm. TL/GW = 8.25.

Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite and telson light brown, antennomeres, sides of metazonite, paranota and legs yellow ( Fig. 32A–D View FIGURE 32 ).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum 3 mm long, 7 mm wide; dorsal surface of all rings smooth and shiny, without microgranulation; posterolateral margins slightly concave ( Fig. 32A, B View FIGURE 32 ). Rings 2–19: prozonite and metazonite smooth and shiny, without microgranulation in dorsal region of all rings. Anterolateral teeth on paranota of rings 2–4 ( Fig. 2G View FIGURE 2 ). Lateral margins of ring 2 not projected posteriad ( Fig. 32A, B View FIGURE 32 ). Gonopodal aperture elliptical, approximately 1.7 mm wide and 1.0 mm long at midpoints. Telson smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Right gonopod structure as follows: coxa with lateral swelling at midlength ( Fig. 33A, C View FIGURE 33 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 33D View FIGURE 33 ); distal region of acropodite lightly sinuous, not bifurcate, curved ventrally at a 60° angle ( Fig. 33A, C View FIGURE 33 ); VP1 emarginated on the posterior region, not very evident, not exceeding the width of ventral region of acropodite, in lateral view ( Fig. 33A, C View FIGURE 33 ); VP2 absent; LP1 long and tapered, hemispheric apex, projected towards the lateral of acropodite ( Fig. 33C, D View FIGURE 33 ), LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite, without projection. Solenomere without projection ( Fig. 33A, C, D View FIGURE 33 ).

Remarks. All species of Haematotropis have peritremata elevated, the most elevated state observed in Haematotropis driki sp. nov. Besides that, the gonopod of this species has peculiar characteristics such as the distal region of the slightly curved dorsal acropodite ( Fig. 33A–D View FIGURE 33 ). H. driki sp. nov. shows characters for the genus: anterolateral teeth in rings 2–4 ( Fig. 2G View FIGURE 2 ), the gonopod with cup-shaped acropodite in the median region ( Fig. 33D View FIGURE 33 ), and the distal region curved ventrally ( Fig. 33A–D View FIGURE 33 ).

Distribution. Brazil: Amazonas ( Fig. 51 View FIGURE 51 ).

Etymology. The new species is named after Dr. Adriano B. Kury, the Brazilian arachnologist, nicknamed Drik.
