Description
Redescription. Body length (Fig. 5) 12–20 mm; length from anterior margin of head to posterior margin of elytra: 7–11 mm. Head and pronotum black, scutellum and elytra yellowish, abdomen yellowish, with tergites 3–5 in middle with dark brown coloured spot with bronze reflections; antennae and anterior tarsi and tibiae dark reddish brown, middle and posterior tarsi and tibiae yellowish. Labrum quadrilobate, with only slightly prominent inner lobes (Fig. 18). Head and pronotum with micro-punctation. Head without postocular punctures (Figs. 18, 64), punctures near posterior margin with fine long setae. Protrusion near posterior angles of head distinct. Anterior margin of pronotum with several fine, long setae. Elytra as long as pronotum, posteriad, slightly dilated and slightly wider than pronotum, with rounded humeral angles; surface with fine and sparse punctation, arranged in three series; with additional punctures near posterior margin and some of these with very long, fine setae. Abdomen with very fine and dense, transverse micro-waves and fine and not sparse punctation. Male. Protrusion near posterior angles of head distinct, in some males similar to that of female, in others, markedly more extended outwards. Temples more or less densely punctured (Fig. 64). Tergite and sternite of male genital segment as in Figs. 66, 67. Aedeagus (Fig. 69) length 1.7–1.8 mm, median lobe very long, with enlarged apex; parameres very large (Fig. 70); internal sac very narrow, covered by very fine and sparse scales. Female. Temples smooth or at most with a few (about 5) fine punctures (Fig. 65). Ratios (n = 12): HL/HW: 0.83–0.91 (M 0.88); TeL/EyL: 1.40–1.83 (M 1.66); PL/PW: 1.01–1.06 (M 1.04); EL/ EW: 0.92 –1.00 (M 0.97); PW/HW: 0.89 –1.00 (M 0.96); EW/PW: 1.01–1.12 (M 1.07); EL/PL: 0.97–1.04 (M 1.01); A 5 L/A 5 W: 0.54–0.71 (M 0.63); A 10 L/A 10 W: 0.54–0.71 (M 0.59). Differential diagnosis.Achmonia amabilis differs from other Afrotropical species of the genus by the yellowish abdomen with tergites 3–5, at middle, with a dark brown coloured spot with bronze reflections, and also by the shape of the aedeagus.
Distribution
Distribution. The species is distributed in D. R. Congo, Kenya, Malawi, Mali and South Africa (Fig. 2). Bionomics. Some specimens were collected in elephant and rhino dung.
Discussion
Remarks.As the labrum of Achmonia amabilis is dark, completely chitinised and quadrilobate (Fig. 64), the species was transferred from Eulissus to Achmonia.
