Acutaspis umbonifera

Acutaspis umbonifera (Newstead, 1920) Fig. 3 Description. The specimens agree with the description presented by Ferris (1941, 1942), with following intraspecific variations (n = 7). Body 924–1354 µm long and 825–1262 µm wide (Fig. 3 A); each margin of prosoma between anterior and posterior spiracles protruded (Fig. 3 B). Antenna 8–11 µm wide, with one seta, 11–18 µm long (Fig. 3 C). Spiracles without associated pores (Fig. 3 D). Pygidium with margins slightly invaginated, forming an acute angle (Fig. 3 E); anal aperture 19–25 µm longitudinal diameter and 13–16 µm transversal diameter, placed 7.3–9.5 times from base of median lobes (L 1), in length 116–132 µm. Macroducts longer than the length between the anal aperture and the base of L 1, each 95–171 µm long (Fig. 3 F). Perivulvar pores clustered into four groups, each containing 6–11 pores (Fig. 3 G). Median (L 1), second (L 2) and third lobes (L 3) are defined and the fourth lobe (L 4) is diffused with the margin; plates present between lobes (Fig. 3 H). Paraphyses numbering 7 on each side, arranged one on each internal and external margin of L 1, L 2 and L 3, plus an interlobular paraphysis between L 2 and L 3 (Fig. 3 I), lengths in order posteroanterior I 17–20 µm, II 28–33 µm, III 15–17 µm, IV 32–36 µm, V 20–24 µm, VI 17–18 µm, VII 27–36 µm; margin anterior to L 4 sclerotised, resembling undefined paraphyses (Fig. 3 J).
