Haematotropis paraensis sp. nov.

Figs 38, 39, 49D, 51

Diagnosis. Adult males of H. paraensis sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 long and tapered, curved apically and projected towards the mesal region (Fig. 39A–C); solenomere short, slightly acuminated apex, projected towards the coxa (Fig. 39A, B).

Material examined. Holotype ♂, Brasil, Pará, rio Mapuera, igarapé do Buçu, 11.VI.1986, equipe Baracuxi leg. (INPA).

Description.

Size and form (holotype ♂). Body length = 32 and wide = 6 mm. TL/GW = 5.

Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite and telson light brown, asymmetrical brown spots on all rings of the metazonite, antennomeres, paranota and legs orange (Fig. 38A–D).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum 2.2 mm long, 6.4 mm wide; dorsal surface of all rings smooth and shiny, without microgranulations; posterolateral margins slightly concave (Fig. 38A, 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 not projected posteriad (Fig. 38A, B). Gonopodal aperture elliptical, approximately 1.67 mm wide and 1.7 mm long at midpoints. Telson (Fig. 38D) smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Left gonopod structure as follows: coxa with lateral swelling at midlength (Fig. 39A, C); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity (Fig. 39D); distal region of acropodite lightly sinuous, bifurcate, curved ventrally at a 75° angle (Fig. 39A–D); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view (Fig. 39A, C); VP2 absent; LP1 long and tapered with apex projected towards the mesal region (Fig. 39A–C), LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite (Fig. 39A, C). Solenomere short, slightly acuminated apex and projected towards the coxa (Fig. 39A, C).

Remarks. H. paraensis sp. nov. is similar to H. amazonica sp. nov. (Fig. 19A–D) with respect to the conformation of the gonopods, but with the acropodite distal region less elevated, VP1 exceeding the width of ventral region of acropodite and LP1 curved apically towards the mesal region (Fig. 39A–D). In H. amazonica sp. nov., the dorsal distal region of acropodite is markedly elevated, VP1 not exceeding the width of ventral region of acropodite in lateral view (Fig. 19A, C) and LP1 projected towards the lateral region of gonopod (Fig. 19A–D).

Distribution. Brazil: Pará (Fig. 51).

Etymology. The specific epithet corresponds to the descriptive adjective for natives from the Brazilian state of Pará.
