Figs 36 View FIGURE 36 , 37 View FIGURE 37 , 49C View FIGURE 49 , 51 View FIGURE 51

Diagnosis. Adult males of H. mosaica sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with LP1 long and tapered, strongly curved apically, apex projected towards the mesal region of gonopod ( Fig. 37A–D View FIGURE 37 ); solenomere long and tapered, truncated apex, projected towards the ventral region region of the body ( Fig. 37A, C View FIGURE 37 ).

Material examined. Holotype ♂, Brasil, Pará , Óbidos , Calha Norte , Estação Ecológica Grão-Pará, Floresta (0º37.831’’S, 55º43.701’’W), 31.I.2009, T. C.S. Ávila-Pires et al. leg. ( MPEG. MYR 123 ).

Paratypes: 1 ♂, Brasil, Pará , Óbidos , Calha Norte , Estação Ecológica Grao Pará, Floresta (0º37.831’’S, 55º43.701’’W), 31.I.2009, T . C.S. Ávila-Pires et al. leg. ( MPEG. MYR 123 ) ; 1 ♂, idem ( INPA) .

Description.

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 dark brown, polygonal areas in all rings of the metazonite, antennomeres, sides of metazonite, paranota, posterior region of epiproct and legs orange ( Fig. 36A–D View FIGURE 36 ).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum 2.7 mm wide, 7 mm long at midpoints; dorsal surface of all rings smooth and shiny, without microgranulations; posterolateral margins slightly concave ( Fig. 36A, B View FIGURE 36 ). 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. 36A, B View FIGURE 36 ). Gonopodal aperture elliptical, approximately 1.9 mm wide and 0.8 mm long at midpoints. Telson ( Fig. 36D View FIGURE 36 ) smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Right gonopod structure as follows: coxa with inconspicuous lateral swelling at midlength ( Fig. 37A, C View FIGURE 37 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 37D View FIGURE 37 ); distal region of acropodite strongly sinuous, bifurcate, narrow, curved ventrally at a 70° angle ( Fig. 37A–D View FIGURE 37 ); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view ( Fig. 37A, C View FIGURE 37 ); VP2 absent; LP1 long and tapered, strongly curved apically, apex projected towards the mesal region of gonopod ( Fig. 37A–D View FIGURE 37 ), LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite ( Fig. 37A, C View FIGURE 37 ). Solenomere long, tapered, truncated apex and projected towards the ventral region of millipede body ( Fig. 37A, B View FIGURE 37 ).

Remarks. Almost all Haematotropis species have polygonal areas on the dorsal region of the metazonites. However, H. mosaica sp. nov. is the only species that has polygonal areas on all rings of body, mainly on the collum ( Fig. 36A–D View FIGURE 36 ). The acropodite distal region is bifurcate as in H. callipa . The difference is that in H. mosaica sp. nov. the solenomere is narrow and projected towards the ventral region of the body ( Fig. 37A, C View FIGURE 37 ), whereas in H. callipa it is wide and projected towards the coxa ( Fig. 4A, B View FIGURE 4 ). Gonopod conformation similar to H. callyi sp. nov., due to sinuosity of distal region of acropodite, but they are differentiated, mainly by the curved LP 1 in H. mosaica sp. nov. ( Fig. 37A–D View FIGURE 37 ), while it is not curved in H. callyi sp. nov. ( Fig. 23A–D View FIGURE 23 ).

Distribution. Brazil: Pará ( Fig. 51 View FIGURE 51 ).

Etymology. The specific epithet mosaicus derives from Latin, making reference to an inlay of small pieces of various colors and patterns, with the polygonal areas on the metazonite of some body rings. Adjective.
