Haematotropis paraensis sp. nov.

Figs 38 View FIGURE 38 , 39 View FIGURE 39 , 49D View FIGURE 49 , 51 View FIGURE 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 View FIGURE 39 ); solenomere short, slightly acuminated apex, projected towards the coxa ( Fig. 39A, B View FIGURE 39 ).

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 View FIGURE 38 ).

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 View FIGURE 38 ). 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. 38A, B View FIGURE 38 ). Gonopodal aperture elliptical, approximately 1.67 mm wide and 1.7 mm long at midpoints. Telson ( Fig. 38D View FIGURE 38 ) 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 View FIGURE 39 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 39D View FIGURE 39 ); distal region of acropodite lightly sinuous, bifurcate, curved ventrally at a 75° angle ( Fig. 39A–D View FIGURE 39 ); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view ( Fig. 39A, C View FIGURE 39 ); VP2 absent; LP1 long and tapered with apex projected towards the mesal region ( Fig. 39A–C View FIGURE 39 ), LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite ( Fig. 39A, C View FIGURE 39 ). Solenomere short, slightly acuminated apex and projected towards the coxa ( Fig. 39A, C View FIGURE 39 ).

Remarks. H. paraensis sp. nov. is similar to H. amazonica sp. nov. ( Fig. 19A–D View FIGURE 19 ) 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 View FIGURE 39 ). 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 View FIGURE 19 ) and LP1 projected towards the lateral region of gonopod ( Fig. 19A–D View FIGURE 19 ).
