Derivatio nominis. amberivery, noun in apposition, after the type and only known locality of the species.
Diagnosis. Characteristic colour with laterally entirely black body rings, which are above the ozopores dorsally bright red with a wide black posterior margin. Collum black, anterior and posterior margin with a red stripe. Head, antenna and legs black. The posterior gonopod with the shorter basal branch and the main branch with the numerous membranous fringes resembles only those of A. hova (deSaussure & Zehntner, 1897). A. amberivery differs from A. hova in fewer body rings (51 versus 54–57 in A. hova ), as well as the anterior gonopod, where the retrorse process is located apically and not medially. Compared to the lectotype of A. hova , the sternite of the anterior gonopods of A. amberivery sp. nov. is single-tipped (double-tipped in A. hova ), and the retrorse process is strongly protruding above the lateral margin of the telopodite (only very slightly protruding in A. hova ). A. amberivery sp. nov. differs from all sampled 6 populations of A. hova in a p-distance of the COI barcoding fragment of 11–12%.
Description
Measurements: 51+0 body rings plus telson, circa 110 mm long, 10.2 mm wide.
Colour faded in ethanol. Body rings laterally entirely black, above ozopores dorsally bright red with a wide black posterior margin. Collum black, anterior and posterior margin with a red stripe ( Fig. 2A View FIGURE 2 ). Head, antenna and legs black ( Fig. 2B View FIGURE 2 ). Telson black, except for anal valves which have a large red spot ( Fig. 2C View FIGURE 2 ).
Head typical for the genus ( Fig. 2A, B View FIGURE 2 ). Antenna short, extending back to ring 4 ( Fig. 2B View FIGURE 2 ).
Ozopore starting at ring 6, located on suture between meso- and metazonite.
Male legs 3–7 with coxae and prefemora slightly invaginated ( Fig. 2B View FIGURE 2 ).
Telson without projecting preanal scale, anal valves without developed lips, subanal scale inconspicuous ( Fig. 2C View FIGURE 2 ).
Anterior gonopod sternite triangular, no shoulders, rounded tip ( Fig. 2D View FIGURE 2 ). Coxite process elongated, slightly shorter than telopodite ( Fig. 2D, E View FIGURE 2 ). Telopodite appendage only weakly swollen, sharp-edged retrorse process starting to project apically ( Fig. 2E View FIGURE 2 ).
Posterior gonopod telopodite branches forming a ‘C’ ( Fig. 2F, G View FIGURE 2 ). Basal branch stout, shorter than main branch ( Fig. 2F View FIGURE 2 ) Tips of main and basal branch distant from one another. Main branch at apically with membranous the numerous membranous fringes ( Figs 2F, G View FIGURE 2 ). Main branch slenderer but much longer than basal branch.
Ecology. A. amberivery occurs in sympatry with two microendemic species of Zoosphaerium Pocock, 1895 ( Sagorny & Wesener 2017), highlighting the only recently protected area of Bemanevika as a center of millipede endemism.
