Candezea atomaria

description: Candezea atomaria (Fairmaire, 1893)   
 Monolepta atomaria Fairmaire, 1893, p 146.   
 Redescription   
 Total length. 6.3–7.8 mm (mean 7.14 mm).   
 Head. Palpi, clypeus, and frons yellow, mandibles apically brown, labrum black. Antennomeres yellow to brownish yellow, only tip of last antennomere brown (Figure 15). Ratio length of second: third antennomere 0.50–0.62 (mean 0.56), ratio length of third: fourth antennomere 0.56–0.71 (mean 0.64).   
 Thorax. Prothorax yellow, meso- and metathorax brownish yellow, rarely black. Pronotal width 1.9–2.4 mm (mean 2.18 mm), ratio pronotal length: width 0.47–0.55 (mean 0.50). Length of elytron 5.1–6.3 mm (mean 5.79 mm), maximal elytral width in the apical third with 3.5–4.2 mm (mean 3.9 mm), elytral width to length 0.62–0.72 (mean 0.66). Elytra yellow to brownish yellow with small, circular, irregularly scattered black spots (Figure 15). Males have a small, heart-shaped elytral protrusion beyond the scutellum (Figure 15A). Scutellum yellow to brownish yellow, legs yellow.   
 Abdomen. Yellow.   
 Female genitalia. Spermatheca large, cornu sometimes strongly curved at apex, nodulus comparatively large, strongly curved, middle part narrow and curved, nodulus moderately enlarged (Figure 17). Bursa sclerites usually with seven spines of varying form, sclerites relatively long and slender (Figure 16).   
 Male genitalia. Median lobe very broad, round in cross-section, slender and parallel-sided in the apical quarter (Figure 18A). Tectum subapically strongly widened, lanceolate, deeply incised at apex, with irregularly, strongly sclerotized spines at margins beyond the lanceolate apex (Figure 18A, B). Endophallic spiculae very strong, ventral pair short and strongly curved outwards (Figure 18A), middle and dorsal pairs much longer, strongly curved dorsally in lateral view (Figure 18B) and slightly curved inwards in dorsal view. Sac structure broad, apically widened in dorsal view. Orifice trapezoidal with two extrusions at base (Figure 18A).   
 Distribution. Candezea atomaria has similar distribution to C. irregularis, a species of Guineo-Congolian forests from Ghana, Cameroon through the Congo Basin to Rwanda and Tanzania in the East and to northern Angola in the South (Figure 19).   
 Diagnosis. With an average total length of 7.14 mm, C. atomaria is the largest Candezea species. According to elytral coloration and male sexual dimorphic sculpturation it is most similar to C. occipitalis, but underside and apical antennomeres (Figure 6) of this species are black. Furthermore, C. occipitalis is allopatrically distributed with C. atomaria. Elytral pattern of both species is very similar to C. costatipennis (Figure 20), but this species is smaller, slenderer, and males have carinate elytra and very different genitalic patterns (Figure 20A). Despite C. atomaria being synomized with C. irregularis by Weise (1924; cf. Wilcox 1973), and both species are sympatric, they can be clearly distinguished by body size (C. irregularis is the smallest Candezea species), size of elytral spots (larger and of different size in C. irregularis, cf. Figures 11, 15), the difference in male sexual dimorphism (Figures 11A, 15A) and male genitalic characters (Figures 14, 18).
