Diagnosis. Adult males of H. poranga sp. nov. differ from other species of Haematotropis based on the following combination of characters: gonopod with short, hemispherical LP1, slightly projected towards the coxa (Fig. 41C); solenomere short, acuminated apex, projected towards the coxa (Fig. 41A, C).

Description.
Size and form (holotype ♂). Body length = 70 and wide = 10 mm. TL/GW = 7.3.
Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite, legs and telson dark brown, antennomeres, sides of metazonite and paranota reddish (Fig. 40A–D).
Head. Dorsal surface smooth and shiny, without microgranulations.
Trunk. Collum 2.5 mm long, 9.3 mm wide; dorsal surface of all rings smooth and shiny, without microgranulations; posterolateral margins strongly concave, sickle-shaped (Fig. 40A, 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. 40A, B). Gonopodal aperture elliptical, approximately 2.0 mm wide and 1.2 mm long at midpoints. Telson (Fig. 40D) smooth and shiny, without microgranulations.
Legs. Smooth and shiny, without microgranulations.
Gonopods. Right gonopod structure as follows: coxa with lateral swelling at midlength (Fig. 41A, C); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity (Fig. 41D); distal region of the acropodite lightly sinuous, not bifurcate, narrow, curved ventrally at a 70° angle; VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view (Fig. 41A, C); VP2 absent; LP1 short and hemispheric, slightly projected towards the coxa (Fig. 41A–D), LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite. Solenomere short, acuminated apex and projected towards the coxa (Fig. 41A, C).
Remarks. Similar to H. jurutiensis sp. nov. (Fig. 30A–D) and H. tysoni sp. nov. (Fig. 42A–D) in the posterolateral margins being strongly concave and the tegument dark brown. The differences are in LP1 being hemispheric in H. poranga sp. nov. (Fig. 41A–D), whereas in H. jurutiensis sp. nov., LP1 is short, with an acuminated apex, almost vestigial (Fig. 31A–D), and in H. tysoni sp. nov. LP1 is long and spatulate (Fig. 43A–D).
Variations. The colour varies from dark brown (nearly black) with paranota reddish to light brown (yellowish) with paranota reddish. Also, some specimens have light-coloured polygonal spots on metazonites.
Distribution. Brazil: Pará (Fig. 51).
Etymology. The specific epithet “ poranga ” is derived from the Tupi language (Brazilian Indian language) meanings “beautiful”. This name refers to the beauty of this species. Noun in apposition.
