Diagnosis. Adult males of H. callipa differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 long and wide, projected towards the ventral region of the body, aculeate margins, slightly projected towards the distal end of acropodite ( Fig. 4A, B, E View FIGURE 4 ); solenomere short and triangular, hemispherical apex, projected towards the coxa ( Fig. 4A, B View FIGURE 4 ).

Material examined. Holotype ♂ (fixed by monotypy, MfN 121 View Materials ), without exact location.

Redescription.

Size and form. Body length = 39 and wide = 5 mm. TL/GW = 7.8.

Coloration (long preserved in 70% ethanol). Uniformly light brown ( Fig. 3A–D View FIGURE 3 ).

Head. Dorsal surface not glossy, with microgranulations.

Trunk. Collum 3 mm long, 8 mm wide; dorsal surface ( Fig. 3A, B View FIGURE 3 ) with microgranulatios; posterolateral margins straight ( Fig. 3A, B View FIGURE 3 ). Rings 2–19: prozonite and metazonite not glossy ( Fig. 3A–D View FIGURE 3 ) with dorsal microgranulations on all rings. Lateral margins of ring 2 not projected posteriad ( Fig. 3A, B View FIGURE 3 ). Anterolateral teeth on paranota of rings 2–4 ( Fig. 2G View FIGURE 2 ). Gonopodal aperture elliptical, approximately 1.6 mm wide and 0.9 mm long at midpoint. Telson not glossy ( Fig. 3D View FIGURE 3 ), with microgranulations.

Legs. Not glossy, with microgranulations.

Gonopods. Left gonopod structure as follows: coxa with lateral swelling at midlength ( Fig. 4A View FIGURE 4 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 4D View FIGURE 4 ); distal region wide, lightly sinuous, bifurcate, ventrally curved at a 70° angle ( Fig. 4A, B View FIGURE 4 ); VP1 emarginated in posterior region, conspicuous, exceeding the width of ventral region of acropodite in lateral view ( Fig. 4A View FIGURE 4 ); VP2 absent; LP1 long and wide, projected towards the ventral region of the body ( Fig. 4A, B View FIGURE 4 ), with aculeate margins, slightly projected towards the distal end of acropodite ( Fig. 4E View FIGURE 4 ); LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite ( Fig. 4A, B View FIGURE 4 ). Solenomere short and triangular, hemispherical apex, projected towards the coxa.

Remarks. Gonopods of H. callipa and H. bella present similar conformation ( Figs 4A, B View FIGURE 4 , 6A–D View FIGURE 6 , 8A, B View FIGURE 8 ), but differ in the bifurcate distal region of acropodite of H. callipa ( Fig. 4A View FIGURE 4 ), LP1 wide ( Fig. 4A, B View FIGURE 4 ) and posterolateral margins of the first rings not projected posteriad ( Fig. 3A, B View FIGURE 3 ). On the other hand, in H. bella , the distal region of the acropodite is not bifurcate ( Figs 6A–D View FIGURE 6 , 8A, B View FIGURE 8 ), LP1 is tapered and the posterolateral margins of the first rings project posteriad ( Fig. 5A, B View FIGURE 5 ). Also, H. callipa is similar to H. macapa , but the former has LP1 wide and emarginate ( Fig. 4E View FIGURE 4 ), while the latter has LP1 tapering ( Fig. 12A–D View FIGURE 12 ). H. callyi sp. nov. and H. mosaica sp. nov. present the acropodite distal region bifurcate ( Figs 4A View FIGURE 4 , 23A–D View FIGURE 23 , 37C View FIGURE 37 ), but differ from H. callipa by solenomere wider in H. callipa ( Fig. 4A, B, E View FIGURE 4 ); solenomere narrower in H. callyi sp. nov. and H. mosaica sp. nov. ( Figs 23B View FIGURE 23 , 37A, C View FIGURE 37 ).

Variations. According to Jeekel (2000), P. callipus (= H. callipa ) varies in colour from brownish to greyish or brownish grey, metazonite yellowish brown and legs yellow, antennae and paranota red (here, light brown, Fig. 3A– D View FIGURE 3 ). While Peters (1864) and Jeekel (2000) described P. callipus as having a smooth and shiny body, we observed microgranulations and striae throughout the body.

Distribution. Suriname: Saramacca, Paramaribo, Brokopondo (Kabelstation), Paloemen ( Jeekel, 2000) ( Fig. 50 View FIGURE 50 ).
