Figs 28 View FIGURE 28 , 29 View FIGURE 29 , 48E View FIGURE 48 , 52 View FIGURE 52

Diagnosis. Adult males of H. goeldii sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 and LP2; LP2 short and hemispherical, projected towards the ventral region of the body; solenomere short, slightly acuminated apex, projected towards the coxa ( Fig. 29A, C View FIGURE 29 ).

Material examined. Holotype ♂, Brasil, Pará , Novo Progresso (07º08.149’S 55º24.818’O), 21.XI.2005, C.O. Araujo leg., NP081 ( MPEG. MYR 106 ). GoogleMaps

Description.

Size and form (holotype ♂). Body length = 56 and wide = 5 mm. TL/GW = 11.2.

Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite, legs and telson dark brown, yellowish hemispheric spot on posterior region of metazonite, antennomeres, sides of metazonite and paranota orange ( Fig. 28A–D View FIGURE 28 ).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum length (mm) 2.0, width 5.5; dorsal surface of all rings smooth and shiny, without microgranulation; posterolateral margins strongly concave, sickle-shaped ( Fig. 28A, B View FIGURE 28 ). 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. 28A, B View FIGURE 28 ). Gonopodal aperture elliptical, approximately 1.5 mm wide and 1 mm long at midpoints. Telson ( Fig. 28D View FIGURE 28 ) smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Right gonopod structure as follows: coxa with lateral swelling at midlength ( Fig. 29A, C View FIGURE 29 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 29D View FIGURE 29 ); distal region of acropodite strongly sinuous, not bifurcate, curved ventrally at a 75° angle ( Fig. 29A, C View FIGURE 29 ); VP1 emarginated on posterior region, not very evident, not exceeding the width of ventral region of acropodite, in lateral view ( Fig. 29C, D View FIGURE 29 ); VP2 absent; LP1 and LP2 short and hemispherical, projected towards the ventral region of the body ( Fig. 29A, C View FIGURE 29 ); LP3 and DP absent. Opening of solenomere located at distal end of acropodite. Solenomere short, slightly acuminated apex, projected towards the coxa ( Fig. 29A, C View FIGURE 29 ).

Remarks. Similar to H. aripuanensis sp. nov. in the colour pattern with hemispherical spots in the posterior region of the metazonites ( Figs 20A–D View FIGURE 20 , 28A–D View FIGURE 28 ). The difference is that LP2 is absent in H. aripuanensis sp. nov. ( Fig. 21A, C View FIGURE 21 ).

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

Etymology. The specific epithet refers to the name of Emilio Goeldi, the founder of the Museu Paraense Emílio Goeldi, Pará State, Brazil, the repository of the species’ type series.
