Araujoleg., NP081 ( MPEG. MYR 106).   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).  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). 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). Lateral margins of ring 2 projected posteriad ( Fig. 28A, B). Gonopodal aperture elliptical, approximately 1.5 mmwide and 1 mmlong at midpoints. Telson ( Fig. 28D) 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); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 29D); distal region of acropodite strongly sinuous, not bifurcate, curved ventrally at a 75° angle ( Fig. 29A, C); VP1 emarginated on posterior region, not very evident, not exceeding the width of ventral region of acropodite, in lateral view ( Fig. 29C, D); VP2 absent; LP1 and LP2 short and hemispherical, projected towards the ventral region of the body ( Fig. 29A, C); 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).   Remarks.Similar to  H. aripuanensis  sp. nov.in the colour pattern with hemispherical spots in the posterior region of the metazonites ( Figs 20A–D, 28A–D). The difference is that LP2 is absent in  H. aripuanensis  sp. nov.( Fig. 21A, C).   Distribution. Brazil: Pará ( Fig. 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’ typeseries. 3424712310 2005-11-21 MPEG C.
