Figs 22, 23, 48B, 52
Diagnosis. Adult males of H. callyi sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 long and wide, projected towards the lateral region of the gonopod (Fig. 23A–D), aculeate margins; solenomere tapered and hooked, projected towards the acropodital apical region (Fig. 23A, B).

Description.
Size and form (holotype ♂). Body length = 43 and wide = 5 mm. TL/GW = 8.6.
Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite and telson dark brown, antennomeres, sides of metazonite, paranota, posterior region of epiproct and legs orange (Fig. 22A–D).
Head. Smooth and shiny, without microgranulations.
Trunk. Collum 2.1 mm long, 4.9 mm wide; dorsal surface of all rings smooth and shiny, without microgranulation; posterolateral margins slightly concave (Fig. 22A, B). Rings 2–19: prozonite and metazonite smooth and shiny, without microgranulation in ventral region of all rings. Anterolateral teeth on paranota of rings 2–4 (Fig. 2G). Lateral margins of ring 2 not projected posteriad (Fig. 22A, B). Gonopodal aperture elliptical, approximately 1.7 mm wide and 0.9 mm long at midpoints. Telson (Fig. 22D) smooth and shiny, without microgranulations.
Legs. Smooth and shiny, without microgranulations.
Gonopods. Right gonopod structure as follows: coxa with lateral swelling at midlength absent (Fig. 23A, C); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity (Fig. 23D); distal region of acropodite strongly sinuous, bifurcate, curved ventrally at a 75° angle (Fig. 23A–D); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view (Fig. 23A, C); VP2 absent; LP1 long and wide, projected towards the lateral region of gonopod, aculeate margins; LP2, LP3 and DP absent (Fig. 23A–D). Opening of solenomere located at distal end of acropodite, at bifurcation. Solenomere tapering, hooked, projected towards the acropodital apical region (Fig. 23A, B).
Remarks. Similar in colour to some specimens such as H. disjuncta (Fig. 9A–E) and H. octocentra (Fig. 15I, J, O, P). Tegument dark brown with appendages and paranota orange. Acropodital distal region bifurcate, with the solenomere originating at the beginning of the bifurcation (Fig. 23A–D), thus differing from the non-bifurcate condition in H. disjuncta and H. octocentra. DP absent, unlike in H. disjuncta (Fig. 10A–C). Gonopods similar to those of H. callipa (Fig. 4A–E) and H. mosaica sp. nov. (Fig. 37A–D). These species have the acropodite distal region bifurcate, but are differentiated mainly by the solenomere, which is narrow and curved in H. callyi sp. nov. (Fig. 23A, B), narrow and projected towards the ventral region of the body in H. mosaica sp. nov. (Fig. 37A, C), and wide in H. callipa (Fig. 4A, B). Gonopod conformation similar to H. mosaica sp. nov. due to the sinuosity of the distal region of the acropodite. Distinguished by LP1 being curved (Fig. 23A–D), versus not curved in H. mosaica sp. nov. (Fig. 37A–D).
Distribution. Brazil: Amapá: Serra do Navio; French Guiana: Camopi (Fig. 52).
Etymology. The specific epithet is dedicated to the collector, Sébastien Cally, from the French National Centre for Scientific Research (CNRS), Paris.
