Diagnosis. Adult males of H. jurutiensis   sp. nov. differ from other Haematotropis species   by the following combination of characters: gonopod with strongly narrow acropodital distal region; short and pointed LP1, projected towards the lateral region of acropodite ( Fig. 31B, D View FIGURE 31 ); solenomere short, slightly acuminated apex, projected towards the ventral region of the body ( Fig. 31A, C View FIGURE 31 ).

Description.

Size and form (holotype ♂). Body length = 58 and wide = 10 mm. TL/GW = 5.8.

Coloration (long preserved in 70% ethanol) Head, prozonite, metazonite, legs and telson dark brown, sides of metazonite and paranota reddish, antennomeres orange ( Fig. 30A–D View FIGURE 30 ).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum 3.5 mm long, 9.1 mm wide; dorsal surface of all rings smooth and shiny, without microgranulations; posterolateral margins strongly concave, sickle-shaped ( Fig. 30A, B View FIGURE 30 ). 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 projected posteriad ( Fig. 30A, B View FIGURE 30 ). Gonopodal aperture elliptical, approximately 2.4 mm wide and 0.8 mm long at midpoints. Telson ( Fig. 30D View FIGURE 30 ) smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Left gonopod structure as follows: coxa with lateral swelling at midlength ( Fig. 31A, C View FIGURE 31 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 31D View FIGURE 31 ); distal region of acropodite lightly sinuous, not bifurcate, curved ventrally at a 70° angle ( Fig. 31A, C View FIGURE 31 ); VP1 emarginated on posterior region and not very evident, not exceeding the width of ventral region of acropodite, in lateral view ( Fig. 31A, C View FIGURE 31 ); VP2 absent; LP1 short and tapered, with the acuminated apex towards the lateral of acropodite ( Fig. 31B, D View FIGURE 31 ), LP2, LP3 and DP absent ( Fig. 31A–D View FIGURE 31 ). Opening of solenomere not located at distal end of acropodite ( Fig. 31A, C View FIGURE 31 ). Solenomere short, slightly acuminated apex, projected towards the lateral region of acropodite ( Fig. 31A, C View FIGURE 31 ).

Remarks. Similar to H. tysoni   sp. nov. ( Fig. 42A–D View FIGURE 42 ) and H. poranga   sp. nov. ( Fig. 40A–D View FIGURE 40 ) by the posterolateral margins strongly concave and tegument dark brown. H. jurutiensis   sp. nov. differs mainly by LP1 being short with an acuminated apex, almost vestigial ( Fig. 31B, D View FIGURE 31 ). LP1 is hemispheric in H. poranga   sp. nov. ( Fig. 41A–D View FIGURE 41 ), and H. tysoni   sp. nov. has LP1 long and spatulated ( Fig. 43A–D View FIGURE 43 ).

Distribution. Brazil: Pará ( Fig. 52 View FIGURE 52 ).

Etymology. The specific epithet refers to the type locality Juruti, Pará State, Brazil.
