Diagnosis.
Calotheca oberprieleri sp. nov. is very similar in shape, size, sculpture and colour to C. pallida and C. prinslooi sp. nov., from which it can be generally distinguished by: surface of median lobe of aedeagus flat ventrally (carinae delimiting a deep sulcus are evident in C. pallida and C. prinslooi sp. nov.) (Figs 2C View Figure 2 , 3C View Figure 3 , 5C View Figure 5 ); median lobe sinuate, narrowing in the apical third, wider basally than apically (sinuate and narrowing medially, and as wide basally as apically in C. pallida ; and greatest width medially, wider basally than apically and tapering towards the apex in C. prinslooi sp. nov.) (Figs 2C View Figure 2 , 3C View Figure 3 , 5C View Figure 5 ); spermatheca only known for one specimen, subreniform and thickset basally (broadly subcylindrical and more slender in C. pallida and C. prinslooi sp. nov.) (Figs 2D View Figure 2 , 3D View Figure 3 , 5D View Figure 5 ); pronotal margins which are more rounded laterally (less rounded or more distinctly curved at apical third respectively in C. pallida and C. prinslooi sp. nov.) (Figs 2B View Figure 2 , 3B View Figure 3 , 5B View Figure 5 ).
Description of the holotype
(♂) . Body elongate-elliptical in dorsal view (Fig. 2A View Figure 2 ), moderately convex in lateral view; total length of body (LB) = 5.00 mm; maximum pronotal width near base (WP = 2.18 mm); maximum width of elytra in basal third (WE = 2.78 mm). Head, femora, and legs pale brown; pronotum yellow, punctate lateral striae and basal furrows distinctly darkened; elytra yellow, with darkened punctures, and small irregular very sparse shaded reddish patches. Head (cf. Fig. 2B View Figure 2 ) with surface microreticulate and micropunctate; several setiferous punctures between medial ocular margin and frontal grooves, and near the dorsal part of frontal grooves; frontal grooves deeply impressed, more so anteriorly, sinuate, extending from dorsal ocular margin to interantennal space; interantennal space about 1.5 times the length of the first antennomere; eyes elongate-ovate; dorsal interocular space slightly wider than 1.5 times the transversal width of the eye; antennae slightly shorter than half the body length (LAN = 2.33 mm; LAN/LB = 0.47; LA: 100:50:75:64:79:79:79:79:79:71:100). Pronotum (cf. Fig. 2B View Figure 2 ) slightly convex, sub-trapezoidal, distinctly transverse (LP = 1.18 mm; WP/LP = 1.85), with clearly rounded sides; surface microreticulate and micropunctate, with additional small, rather dense, evenly distributed punctation; lateral pronotal striae C-shaped, with large, deeply impressed punctures; basal furrows of pronotum deeply impressed; basal and apical margins distinctly bordered, but not raised; lateral margins barely expanded, but visible in dorsal view; anterior angles prominent and pointed; posterior angles widely obtuse. Scutellum sub-triangular, rounded apically. Elytra (Fig. 2A View Figure 2 , cf. 2B) moderately elongate and convex (LE = 3.83 mm; WE/LE = 0.73; LE/LP = 3.26), slightly sinuate laterally, jointly rounded apically; lateral margin narrow, barely visible in dorsal view; elytral punctation arranged in single regular rows, punctures deeply impressed; interstriae with finely microreticulate and micropunctate surface; last interstria carinate; humeral calli barely raised. Macropterous. Legs with basal pro- and mesotarsomeres distinctly enlarged, sub-triangular (Fig. 2A View Figure 2 ). Tarsal claws simple. Underside pale brown; apical abdominal ventrite without preapical sculpture or impressions. Median lobe of aedeagus (cf. Fig. 2C View Figure 2 ) (LAED = 2.08 mm; LE/LAED = 1.84) distinctly sinuate laterally in ventral view; slightly narrower distally than basally; apex subrounded, with small ventrolateral bulges; ventral surface flat, with a narrow medial furrow in distal third; ventrolateral surface widely wrinkled; dorsal ligula short, formed by two elongate basal lobes and two shorter apical lobes; in lateral view, median lobe distinctly bent down to the apex.
Variability.
Males (n = 4; mean ± standard deviation, range): LE = 3.99 ± 0.17 mm (3.83 ≤ LE ≤ 4.12 mm); WE = 2.88 ± 0.12 mm (2.78 ≤ WE ≤ 3.05 mm); LP = 1.21 ± 0.04 mm (1.18 ≤ LP ≤ 1.28 mm); WP = 2.30 ± 0.12 mm (2.18 ≤ WP ≤ 2.45 mm); LAN = 2.37 ± 0.11 mm (2.25 ≤ LAN ≤ 2.50 mm); LAED = 2.10 ± 0.12 mm (2.00 ≤ LAED ≤ 2.28 mm); LB = 5.12 ± 0.12 mm (5.00 ≤ LB ≤ 5.28 mm); LE/LP = 3.29 ± 0.06 (3.25 ≤ LE/LP ≤ 3.38); WE/WP = 1.25 ± 0.02 (1.24 ≤ WE/WP ≤ 1.28); WP/LP = 1.90 ± 0.04 (1.85 ≤ WP/LP ≤ 1.94); WE/LE = 0.72 ± 0.01 (0.72 ≤ WE/LE ≤ 0.73); LAN/LB = 0.46 ± 0.02 (0.44 ≤ LAN/LB ≤ 0.48); LE/LAED = 1.90 ± 0.08 (1.84 ≤ LE/LAED ≤ 2.03). Females (n = 1): LE = 4.50 mm; WE = 3.38 mm; LP = 1.28 mm; WP = 2.65 mm; LAN = 2.35; LSP = 0.80 mm; LB = 5.75 mm; LE/LP = 3.53; WE/WP = 1.27; WP/LP = 2.08; WE/LE = 0.75; LAN/LB = 0.41; LE/LSP = 5.63. Paratypes very similar in shape, sculpture and colour to the holotype. Female with basal pro- and mesotarsomeres less enlarged than in male. Spermatheca (Fig. 2D View Figure 2 ) with basal part subreniform, thickset; distal part softly bent, slightly narrower apically, with a very short appendix; distal part clearly shorter than half the length of the basal part; ductus basally inserted, moderately elongate, and with a hint of a coil.
Etymology.
The specific epithet is a noun in the genitive case after Rolf G. Oberprieler (Australia, Canberra), one of its collectors.
Distribution.
Republic of South Africa (ECape) (Fig. 6 View Figure 6 ). Chorotype: Southern-Western Afrotropical (SWA).
