Haematotropis aripuanensis sp. nov.

Figs 20 View FIGURE 20 , 21 View FIGURE 21 , 48A View FIGURE 48 , 52 View FIGURE 52

Diagnosis. Adult males of H. aripuanensis sp. nov. differ from other Haematotropis species based on the following combination of characters: gonopod with long and spatulate LP1 with slightly pointed apex, projected towards the coxa ( Fig. 21A–D View FIGURE 21 ); solenomere short with slightly acuminated apex, projected towards the ventral region of the body ( Fig. 21A, C View FIGURE 21 ).

Material examined. Holotype ♂, Brasil, Mato Grosso, Aripuanã , 22.VIII–2.IX.1997, G. Skuk leg. ( MZUSP 969 View Materials ).

Description.

Size and form (holotype ♂). Body length = 59 and wide = 8 mm. TL/GW = 7.3.

Coloration (long preserved in 70% ethanol). Head, prozonite, metazonite and telson brown, yellowish hemispheric spot in posterior region of the metazonite and posterior region of epiproct, antennomeres, paranota and legs orange ( Fig. 20A–D View FIGURE 20 ).

Head. Dorsal surface smooth and shiny, without microgranulations.

Trunk. Collum 2.8 mm long, 7.6 mm wide; dorsal surface of all rings smooth and shiny, without microgranulations; posterolateral margins strongly concave, sickle-shaped ( Fig. 20A, B View FIGURE 20 ). Rings 2–19: prozonite and metazonite smooth and shiny, without microgranulation in the dorsal region of all rings. Anterolateral teeth on paranota of rings 2–4 ( Fig. 2G View FIGURE 2 ). Lateral margins of ring 2 projected posteriad ( Fig. 20A, B View FIGURE 20 ). Gonopodal aperture elliptical, approximately 2.11 mm wide and 1.3 mm long at midpoints. Telson ( Fig. 20D View FIGURE 20 ) smooth and shiny, without microgranulations.

Legs. Smooth and shiny, without microgranulations.

Gonopods. Right gonopod structure as follows: coxa with lateral swelling at midlength ( Fig. 21A, C View FIGURE 21 ); acropodite elongated, about four times as long as prefemur; median region expanded, cup-shaped in ventral view, with a concavity and cavity ( Fig. 21D View FIGURE 21 ); distal region of acropodite strongly sinuous, not bifurcate, curved ventrally at an 90° angle ( Fig. 21A–D View FIGURE 21 ); VP1 emarginated on posterior region, not very evident, not exceeding the width of ventral region of acropodite, in lateral view ( Fig. 21A, C View FIGURE 21 ); VP2 absent; LP1 long and spatulate, hemispheric apex, projected towards the coxa ( Fig. 21A–D View FIGURE 21 ), LP2, LP3 and DP absent. Opening of solenomere not located at the distal end of acropodite. Solenomere short, slightly acuminated apex, projected towards the ventral region of millipede body ( Fig. 21A, C View FIGURE 21 ).

Remarks. Similar to H. goeldii sp. nov. ( Fig. 28A–D View FIGURE 28 ) with respect to the colour pattern with hemispherical spots in the posterior region of the metazonites. Distal region of the acropodite more sinuous than H. goeldii sp. nov. ( Fig. 29A, C View FIGURE 29 ). Only LP1 is observed ( Fig. 21A–D View FIGURE 21 ), whereas in H. goeldii sp. nov., LP1 and LP2 are present ( Fig. 29A,C View FIGURE 29 ).
