Haematotropis amazonica sp. nov.
Figs 18 View FIGURE 18 , 19 View FIGURE 19 , 47F View FIGURE 47 , 52 View FIGURE 52
Diagnosis. Adult males of H. amazonica sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 long and tapered, projected towards the lateral region of gonopod ( Fig. 19A–D View FIGURE 19 ); solenomere short, with apex slightly acuminated, projected towards the coxa ( Fig. 19A, C View FIGURE 19 ).
Material examined. Holotype ♂, Brasil, Amazonas , Presidente Figueiredo, Usina Hidrelétrica de Balbina, 01.II.1988, B.M. Mascarenhas leg. ( MPEG. MYR 125 ).
Paratypes: 1 ♂, same data as holotype, II.1988 ( MPEG. MYR 174 ) ; 1 ♂, same data as holotype ( INPA) .
Description.
Size and form (holotype ♂). Body length = 51 and wide = 6 mm. TL/GW = 8.5.
Coloration (long preserved in 70% ethanol). Head, prozonite, matazonite and telson brown, antennomeres, sides of metazonite, paranota, posterior region of epiproct and legs orange ( Fig. 18A–D View FIGURE 18 ).
Head. Dorsal surface smooth and shiny, without microgranulations.
Trunk. Collum 2.0 mm long, 5.8 mm wide; dorsal surface of all rings smooth and shiny, without microgranulation; posterolateral margins slightly concave ( Fig. 18A, B View FIGURE 18 ). 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 View FIGURE 2 ). Lateral margins of ring 2 not projected posteriad ( Fig. 18A, B View FIGURE 18 ). Gonopodal aperture elliptical, approximately 1.6 mm wide and 1.0 mm long at midpoints. Telson ( Fig. 18D View FIGURE 18 ) smooth and shiny, without microgranulations.
Legs. Smooth and shiny, without microgranulations.
Gonopods. Right gonopod structure as follows: coxa with inconspicuous lateral swelling at midlength ( Fig. 19A View FIGURE 19 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 19D View FIGURE 19 ); distal region of acropodite lightly sinuous, not bifurcate, curved ventrally at a 80° angle ( Fig. 19A–C View FIGURE 19 ); VP1 emarginated on posterior region, not very evident, not exceeding the width of ventral region of acropodite, in lateral view ( Fig. 19A, C View FIGURE 19 ); VP2 absent; LP1 long and tapered, projected towards the lateral region of gonopod, apex slightly inclined ( Fig. 19A–D View FIGURE 19 ), LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite ( Fig. 19A–C View FIGURE 19 ). Solenomere short, slightly acuminated apex, projected towards the coxa ( Fig. 19A, C View FIGURE 19 ).
Remarks. H. amazonica sp. nov. is similar to H. paraensis sp. nov., in the conformation of the gonopods. It differs by the dorsal distal region of the acropodite being strongly elevated, VP1 not exceeding the width of ventral region of acropodite in lateral view ( Fig. 19A View FIGURE 19 ), and LP1 projected towards the lateral region of the gonopod ( Fig. 19A–D View FIGURE 19 ), while in H. paraensis sp. nov., the ventral region of the acropodite is slightly elevated ( Fig. 39A–C View FIGURE 39 ), VP1 exceeding the width of ventral region of acropodite, in lateral view ( Fig. 39C View FIGURE 39 ) and LP1 projects towards the mesal region of the gonopod ( Fig. 39A–D View FIGURE 39 ).
Distribution. Brazil: Amazonas ( Fig. 52 View FIGURE 52 ).
Etymology. The name refers to the region where the species was collected.
