Figure 4 in Taxonomy of the enigmatic genus Acanthoniscus Gosse, 1851 (Isopoda: Oniscidea: Armadillidae), from Jamaica, with the description of a new species

Figure 4. Body parts of Acanthoniscus richardsonae sp. nov. A, Overall, dorsal view; B, detail of the microsculpture of the dorsal tegument (left) and tricorn-like setae (right); C, lateral view of the anterior region of the body; D, lateral view of the posterior region of the body; E, right pleon-epimera 3–5 in ventral view; F, right pereon-epimera 1–7 in ventral view; G, detail of pereon-epimera 1–2 in a more ventral position; H, cephalothorax in dorsal view; I, cephalothorax in frontal view (the tiny sensory setae inserted between the ommatidia are illustrated under a magnification of 400×: a, b, c); J, cephalothorax in ventral view; K, pleotelson and uropods in dorsal view (the uropod exopodites are slightly pointing upward); L, pleotelson and uropods in ventral view; M, right uropod in ventral view; N, right uropod in dorsal view; O, drawing of the overall dorsal view modified from Richardson (1909); P, arrangement of dorsal spines, the diameters of the circles correspond to the relative size of the spines. Drawings of the corresponding structures modified from Richardson (1909) are included in I, J (the question mark means that the position representing the drawing is not totally clear) and in M. Abbreviations: sympodite (sy), endopodite (en), and exopodite (ex). Scale bars = 1 mm (A–L), 0.5 mm (M–N); in some cases, a single scale bar applies to more than one figure (indicated by the letters above the scale bar).
