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 View FIGURE 23 ), aculeate margins; solenomere tapered and hooked, projected towards the acropodital apical region ( Fig. 23A, B View FIGURE 23 ).

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 View FIGURE 22 ).

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 View FIGURE 22 ). 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 View FIGURE 2 ). Lateral margins of ring 2 not projected posteriad ( Fig. 22A, B View FIGURE 22 ). Gonopodal aperture elliptical, approximately 1.7 mm wide and 0.9 mm long at midpoints. Telson ( Fig. 22D View FIGURE 22 ) 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 View FIGURE 23 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 23D View FIGURE 23 ); distal region of acropodite strongly sinuous, bifurcate, curved ventrally at a 75° angle ( Fig. 23A–D View FIGURE 23 ); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view ( Fig. 23A, C View FIGURE 23 ); VP2 absent; LP1 long and wide, projected towards the lateral region of gonopod, aculeate margins; LP2, LP3 and DP absent ( Fig. 23A–D View FIGURE 23 ). Opening of solenomere located at distal end of acropodite, at bifurcation. Solenomere tapering, hooked, projected towards the acropodital apical region ( Fig. 23A, B View FIGURE 23 ).

Remarks. Similar in colour to some specimens such as H. disjuncta ( Fig. 9A–E View FIGURE 9 ) and H. octocentra ( Fig. 15I, J, O, P View FIGURE 15 ). 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 View FIGURE 23 ), thus differing from the non-bifurcate condition in H. disjuncta and H. octocentra . DP absent, unlike in H. disjuncta ( Fig. 10A–C View FIGURE 10 ). Gonopods similar to those of H. callipa ( Fig. 4A–E View FIGURE 4 ) and H. mosaica sp. nov. ( Fig. 37A–D View FIGURE 37 ). 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 View FIGURE 23 ), narrow and projected towards the ventral region of the body in H. mosaica sp. nov. ( Fig. 37A, C View FIGURE 37 ), and wide in H. callipa ( Fig. 4A, B View FIGURE 4 ). 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 View FIGURE 23 ), versus not curved in H. mosaica sp. nov. ( Fig. 37A–D View FIGURE 37 ).

Distribution. Brazil: Amapá: Serra do Navio; French Guiana: Camopi ( Fig. 52 View FIGURE 52 ).

Etymology. The specific epithet is dedicated to the collector, Sébastien Cally, from the French National Centre for Scientific Research (CNRS), Paris.
