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
).

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.
