Haematotropis macapa Golovatch, Hoffman & Spelda in Golovatch et al., 2004: 64, figs 39–46.
Diagnosis. Adult males of H. macapa differ from other Haematotropis species, based on the following combination of characters: gonopod with LP1 long and tapered, strongly curved apically, projected towards the mesal region of gonopod (Fig. 12A–D); solenomere short, triangular, hemispherical apex, projected towards the coxa (Fig. 12A–C).
Material examined. Holotype ♂, Brasil, Amapá, Macapá, in litter of flowering plants Eugenia sp., in jambeiro (rose apple) tree of garden, 14.II.2000, E.O. Oliveira leg. (IEPA). Paratype: 1 ♂, same data as holotype (IEPA).
Redescription.
Size and form (holotype ♂). Body length = 34 and wide = 5 mm. TL/GW = 6.8.
Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite and telson brownish, antennomeres, paranota, posterior region of the epiproct and legs yellow (Fig. 11A–D).
Head. Dorsal surface smooth and shiny, without microgranulations. Trunk. Collum 2.6 mm long, 6.3 mm wide; dorsal surface of all rings smooth and shiny, without microgranulation; posterolateral margins straight (Fig. 11A, 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 laterally not projected posteriad (Fig. 11A, B). Gonopodal aperture elliptical, aproximately 1.7 mm wide and 1.1 mm long at midpoints. Telson (Fig. 11D) smooth and shiny, without microgranulations.
Legs. Smooth and shiny, without microgranulations.
Gonopods. Left gonopod structure as follows: coxa with lateral swelling at midlength (Fig. 12A); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity (Fig. 12D); distal region of acropodite strongly sinuous, bifurcate, curved ventrally at a 70° angle (Fig. 12A, C); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view (Fig. 12A, C); VP2 absent; LP1 long and tapered, strongly curved apically, projected towards the mesal region of gonopod (Fig. 12A–D); LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite (Fig. 12A, C). Solenomere short, triangular, hemispherical apex, projected towards the coxa (Fig. 12A, C).
Remarks. H. macapa is similar to H. callipa, considering the conformation of the gonopods. However, H. macapa is shorter (34 mm) than H. callipa (39 mm) in length, and its gonopods LP1 are tapering (Fig. 12A–D). In H. callipa, they are emarginate and wide (Fig. 4E). Also, H. macapa differs from H. bella by the distal region of acropodite being bifurcate (Fig. 12A, C) – not bifurcate in H. bella (Figs 6A–C, 8A, B).
Golovatch et al. (2004) cited the presence of small anterolateral teeth only on paranota of ring 3 for H. macapa, but we detected them on paranota of rings 2–4 as well.
Distribution. Brazil: Amapá (Fig. 50).
