Haematotropis disjuncta Golovatch, Hoffman & Spelda View in CoL in Golovatch et al., 2004: 64, figs 47–52.

Diagnosis. Adult males of H. disjuncta differs 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. 10A–D View FIGURE 10 ); DP present with apex not bifurcate ( Fig. 10A–C View FIGURE 10 ); solenomere long, apex acuminated, projected towards the LP1 ( Fig. 10A–C View FIGURE 10 ).

Material examined. Holotype ♂, Brasil, Amapá, road-km 94 of BR-156 highway, in rotten leaves of palms Elaeis oleifera (Kunth) Cortés and E. guineensis Jacq. , 14.II.2000, E.L. Oliveira leg. ( IEPA). Paratypes: All from Brasil: 2 ♂♂, 3 ♀♀, same data as holotype ( IEPA); 1 ♂, 2 ♀♀ ( INPA).

Additional material examined: All from Brasil, Amapá, Macapá : 3 ♂♂, Fazendinha IEPA , Parque Zoobotânico, I.2001, P. Magno leg. ( MNRJ 12012 View Materials ); 1 ♂, 1 ♀, same data ( MNRJ 12011 View Materials ); 1 ♂, Fazendinha, Distrito, campus do IEPA , 17–20.IX.2004, C.J.F. Costa & P. Magno leg. ( MNRJ 12010 View Materials ) .

Redescription.

Size and form (holotype ♂). Body length = 42 and wide = 7 mm. TL/GW = 6.

Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite and telson brown, antennomeres, paranota and posterior region of the epiproct orange, legs yellow ( Fig. 9A–E View FIGURE 9 ).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum 3 mm long, 7 mm wide; dorsal surface of all rings smooth and shiny, without microgranulations; posterolateral margins slightly concave ( Fig. 9A, B View FIGURE 9 ). 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. 9A, B View FIGURE 9 ). Gonopodal aperture elliptical, approximately 1.5 mm wide and 0.5 mm long at midpoints. Telson ( Fig. 9D View FIGURE 9 ) smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Right gonopod structure as follows: coxa with lateral swelling at midlength ( Fig. 10C View FIGURE 10 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 10D View FIGURE 10 ); distal region of acropodite slightly sinuous, not bifurcate, curved ventrally at a 70° angle ( Fig. 10A–C View FIGURE 10 ); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view ( Fig. 10A, C View FIGURE 10 ); VP2 absent; LP1 long and tapered, strongly curved apically, projected towards the mesal region of gonopod ( Fig. 10A–D View FIGURE 10 ), LP2 and LP3 absent; DP tapered, sinuous and projected towards the gonopod apical region ( Fig. 10A–C View FIGURE 10 ). Opening of solenomere located at distal end of acropodite ( Fig. 10A–C View FIGURE 10 ). Solenomere with long, acuminated apex, projected towards LP1 ( Fig. 10A–C View FIGURE 10 ).

Remarks. H. disjuncta is very similar to H. disjunctoides sp. nov. in the conformation of both gonopods and the presence of DP ( Figs 10A–D View FIGURE 10 , 26A–D View FIGURE 26 ). However, the apex of DP not being bifurcate and not surpassing the dorsal distal region of the acropodite ( Fig. 10A–D View FIGURE 10 ) distinguishes H. disjuncta from H. disjunctoides sp. nov., in which DP bifurcates irregularly and extends beyond the dorsal distal region of the acropodite ( Fig. 27A–C View FIGURE 27 ). H. disjuncta occurs mainly on the north shore of the Amazon River ( Fig. 50 View FIGURE 50 ) while H. disjunctoides sp. nov. occurs on the south shore ( Fig. 52 View FIGURE 52 ), supporting the separation of the two species.
