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 ).
