Nel leg. (SANC).
Diagnosis.
Calotheca carolineae sp. nov. displays major similarities with C. nigromaculata and C. wanati sp. nov., more so than with other known Calotheca species. It is mainly characterized by the differently shaped median lobe of the aedeagus (Figs 1B View Figure 1 , 2F View Figure 2 , 3B View Figure 3 ) which is not sinuate in lateral view, and widely rounded in the apical part in ventral view (in C. nigromaculata , even though quite variable, it is curved in proximal 1/2 and distinctly sinuate in apical 1/2 in lateral view, and produced and subtruncate apically in ventral view; in C. wanati sp. nov. it is curved in proximal 1/2 and more distinctly curved in apical 1/2 in lateral view, and produced and sub-rhomboidal in the apical 1/4, with prominent angulate lateral projections in ventral view). Other differences include: color of the dorsal integument with more clearly defined and generally larger colored elytral patches, reddish-brown on a yellow background (smaller and more confused, from brown to black, in C. nigromaculata and C. wanati sp. nov.) (Figs 1A View Figure 1 , 2A-C View Figure 2 , 3A View Figure 3 ); punctate lateral pronotal striae less dark (Figs 1A View Figure 1 , 2A-C View Figure 2 , 3A View Figure 3 ); antennae generally longer with LAN/(LE+LP) = 0.48 ± 0.01 in male, and = 0.41 ± 0.01 in female (in C. nigromaculata LAN/(LE+LP) = 0.42 ± 0.02 in male, and = 0.38 ± 0.02 in female; in C. wanati sp. nov. LAN/(LE+LP) = 0.42 ± 0.02 in male, and = 0.37 ± 0.02 in female) (Fig. 4A View Figure 4 ); shape of the pronotum, straight laterally in basal 2/3 and abruptly incurved in apical 1/3 (slightly curved in basal 2/3 and distinctly incurved in apical 1/3 in C. nigromaculata and C. wanati sp. nov.) (Figs 1C View Figure 1 , 2D View Figure 2 , 3C View Figure 3 ).
Description of the holotype
(♂). Body elliptical in dorsal view (Fig. 1A View Figure 1 ), rather convex in lateral view; total body length (LB) = 7.00 mm; maximum pronotal width in the apical third (WP = 3.05 mm); maximum width of elytra in the basal 1/3 (WE = 3.85 mm). Head and antennae pale brown, with antennomeres 6-11 slightly darker (Fig. 1A View Figure 1 ); head surface microreticulate, with evident setiferous punctures on most of the vertex and part of the frons (Fig. 1C View Figure 1 ); frontal grooves sinuate, deeply impressed, extending approximately from the dorsal ocular margin to the inter-antennal space (Fig. 1C View Figure 1 ); eyes elliptical, clearly elongate; antennae slightly shorter than half the body length (LAN = 3.15 mm; LAN/LB = 0.45); LA: 100:44:61:63:73:68:73:68:73:63:88. Pronotum (Fig. 1A, C View Figure 1 ) slightly convex, pale brown; punctate lateral stria, basal dimples and margins slightly darker; distinctly transverse in dorsal view (LP = 1.53 mm; WP/LP = 2.00), sub-rectangular, distinctly incurved laterally in the anterior third only; surface microreticulate, with minute punctation; anterolateral surface with very shallow depressions; lateral punctate striae distinctly impressed, C-shaped and slightly curved on the disc; some additional sparse punctures along the pronotal margins; basal furrows short and moderately incised; anterior and basal margins finely bordered, lateral margins thickened slightly, poorly visible in dorsal view; anterior angles distinctly prominent, moderately swollen; posterior angles obtuse. Scutellum brown, sub-triangular. Elytra (Fig. 1A View Figure 1 ) pale yellow, with irregular wide brown patches and dark punctation; elytra moderately elongate (LE = 5.10 mm; WE/LE = 0.75; LE/LP = 3.34), distinctly sinuate laterally, jointly rounded apically; lateral margin narrow, visible in dorsal view; elytral punctation arranged in single regular rows formed by distinctly impressed punctures; interstriae flat on the elytral disc, with finely microreticulate and sparsely micropunctate surface; humeral calli indistinctly raised. Macropterous. Basal pro- and mesotarsomeres clearly enlarged (Fig. 1A View Figure 1 ). Underside pale brown; apical abdominal ventrite without preapical sculptures or impressions. Median lobe of the aedeagus (LAED = 2.65 mm; LE/LAED = 1.92) (Fig. 1B View Figure 1 ) with subparallel sides in ventral view, widely rounded in the apical part; ventral surface with a pair of lateral U-shaped depressions with a wrinkled surface in the distal half, and evident punctation apically; moderately and evenly curved up to the apex in lateral view; dorsal ligula short, formed by a wide subtriangular, apically truncate median lobe, and two narrow lateral lobes.

Spermatheca (Fig. 1D View Figure 1 ) sub-fusiform and elongate basally, narrowing towards the ductus attachment; distal part distinctly curved and about 2/3 the basal part in length, with a distinct appendix; ductus basally inserted, thickset, short, uncoiled, roughly U-shaped.
Etymology.
The specific epithet is a noun in the genitive case after our friend Caroline S. Chaboo (University of Nebraska-Lincoln, Nebraska, USA), one of its collectors and appreciated expert of chrysomelid Coleoptera .
Distribution.
Republic of South Africa (KZN) (Fig. 5 View Figure 5 ). Chorotype: Southern-Eastern African (SEA).
