Candezea costatipennis Laboissière, 1931

Candezea costatipennis Laboissière, 1931, p 412.

Redescription

Total length. 6.5–7.1 mm (mean 6.86 mm).

Head. Labrum black, labial and maxillary palpi, clypeus, and frons yellow. Antennae yellow to brownish yellow (Figure 20B), rarely outer part of distal four antennomeres brown (Figure 20A). Ratio length of second: third antennomere 0.50–0.61 (mean 0.56), ratio length of third to fourth antennomere 0.59–0.65 (mean 0.62).

Thorax. Pronotum yellow to brownish yellow, underside of prothorax, meso- and metathorax black. Pronotal width 2.0– 2.3 mm (mean 2.12 mm), ratio pronotal length: width 0.50–0.59 (mean 0.52). Elytra 5.1–6.2 mm (mean 5.54 mm) long, maximal elytral width in the apical half 3.3–3.8 mm (mean 3.54 mm), elytra narrow, ratio maximal width: length 0.61–0.65 (mean 0.63). Elytra yellow to yellowish brown with small, circular, irregularly scattered black spots (Figure 20). Males with heart-shaped, small extrusion beyond scutellum and long ridges laterally on each elytron from humerus to the distal third (Figure 20A). Scutellum yellow to brownish yellow, legs entirely yellow.

Abdomen. Usually entirely black (Figure 20A), rarely entirely yellow (Figure 20B).

Female genitalia. Cornu of spermatheca slightly curved apically, broad; nodulus small (Figure 22); bursa sclerites large, usually with six or seven spines (Figure 21).

Male genitalia. Median lobe slender, straight, slightly depressed dorsoventrally, parallelsided, strongly narrowed in the apical third (Figure 23A). Tectum lanceolate, strongly enlarged beyond apex, deeply incised at apex (Figure 23A). All pairs of endophallic spiculae equally bent dorsally (Figure 23B), but all of different length, ventral pair shortest, curved outwards, middle pair longer, dorsal pair longest, slightly curved inwards. Orifice ovate, with shallow incision (Figure 23A, B).

Distribution. Only 35 specimens were found amongst the material studied. Candezea costatipennis is a rare species of dry savannas of Angola (Figure 28).

Diagnosis. Males of C. costatipennis can be easily distinguished from other Candezea species by the lateral elytral ridges and the small black elytral spots, a combination unique to this species. Females are most similar to C. occipitalis, but this species is allopatrically distributed in Ethiopia and Eritrea. Furthermore, C. occipitalis has entirely black legs while C. costatipennis has yellow legs. Candezea atomaria has the same elytral coloration, but is much larger, has broader elytra and has different genitalic pattern (Figures 16–18, 21–23).

Type material

Lectotype: „, ‘‘ Lectotypus Th. Wagner desig. 99/ Paratype (male) costatipennis / Angola / Kalukembe Dec./Musée du Congo angola: Kalukembe—XII—(Don Laboissière)/ R. Dét. C 3620 / Paratype Candezea costatipennis m. V. Laboissière — Dét. ’’ (MRAC). Type locality: Angola, Kalukembe, 13 ° 469S, 14 ° 419E. Paralectotypes: 1♀, same label as lectotype; 2♀, ‘‘ Angola, Miss. se. Suisse 1928–29, V. A. Ponte’ ’ (IRSNB). Laboissière mentioned 14 ex. in his original publication. A lectotype is here designated to fix the name and to ensure its universal and consistent interpretation, since neither on the type material nor in the original publication was a holotype designated.
