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.
