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); solenomere long and tapered, truncated apex, projected towards the ventral region region of the body (Fig. 37A, C).
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).
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). 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). Lateral margins of ring 2 not projected posteriad (Fig. 36A, B). Gonopodal aperture elliptical, approximately 1.9 mm wide and 0.8 mm long at midpoints. Telson (Fig. 36D) 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); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity (Fig. 37D); distal region of acropodite strongly sinuous, bifurcate, narrow, curved ventrally at a 70° angle (Fig. 37A–D); VP1 emarginated on posterior region, evident, exceeding the width of ventral region of acropodite, in lateral view (Fig. 37A, C); VP2 absent; LP1 long and tapered, strongly curved apically, apex projected towards the mesal region of gonopod (Fig. 37A–D), LP2, LP3 and DP absent. Opening of solenomere located at distal end of acropodite (Fig. 37A, C). Solenomere long, tapered, truncated apex and projected towards the ventral region of millipede body (Fig. 37A, B).
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). 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), whereas in H. callipa it is wide and projected towards the coxa (Fig. 4A, B). 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), while it is not curved in H. callyi sp. nov. (Fig. 23A–D).
Distribution. Brazil: Pará (Fig. 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.
