Cassida unimaculata Boheman, 1854: 466 , 1856: 141, 1862: 343; Gemminger & Harold, 1876: 3659; Shaw, 1956: 270; Heron & Borowiec, 1997: 632; Borowiec, 1999 a: 290, 2005 a: 127; Heron, 2003: 33.

Cassida unimacula [sic]: Muir & Sharp, 1904: 8, 14 (larva, pupa, biology).

Cassida (Cassida) unimaculata: Spaeth, 1914 b: 119 .

Description. L: 5.20–6.20 mm, W: 4.35–5.10 mm, Lp: 2.00–2.30 mm, Wp: 3.05–3.55 mm, L/W: 1.12–1.22, Wp/ Lp: 1.52–1.63. Body almost circular ( figs. 326, 327 View FIGURES 326–328 ).

Pronotum and scutellum uniformly yellow. Elytral disc yellow, at top of disc with small, round or elongate black spot, only occasionally the spot reduced to a narrow stripe. Explanate margin always yellow ( figs. 326–328 View FIGURES 326–328 ). Head, ventrites, legs and antennae uniformly yellow.

Pronotum reversely trapezial, with maximum width in anterior third, anterior margin slightly convex, sides rounded, no basal corners. Disc indistinctly bordered from explanate margin, without lateral lobes and lateral impressions, Surface of disc shiny, impunctate. Explanate margin broad, impunctate, shiny, transparent with well visible honeycomb structure.

Base of elytra moderately wider than base of pronotum, humeral angles distinctly protruding anterad, angulate. Disc slightly irregularly convex in profile, with top of convexity in postscutellar area ( fig. 328 View FIGURES 326–328 ), without or with very shallow postscutellar and principal impressions, without H–shaped elevation or any other sculpture. Punctation moderately coarse arranged in completely regular rows, moderately sparse, distance between punctures mostly from as wide as to twice wider than puncture diameter. Marginal row distinct, its punctures slightly smaller than punctures in central rows. Intervals flat, on top of disc twice to thrice wider than rows, on sides mostly as wide as rows, marginal interval as wide as submarginal interval and two submarginal rows combined, no humeral or lateral folds. Explanate margin moderately broad, moderately declivous, in the widest part four times narrower than disc, surface shiny with shallow, moderately coarse punctation, appears more or less regular, transparent with well visible honeycomb structure.

Eyes moderately large, gena slightly shorter than last palpomere. Clypeus very broad, approximately 1.5 times as wide as long. Clypeal grooves fine but well marked, converging in regular triangle, area between clypeal plate and margin of eye with a row of hairy punctures, surface of clypeus flat, shiny with several very small setose punctures. Labrum shallowly emarginate. Antennae moderately slim, segments 9–10 approximately 1.2 times as long as wide. Length ratio of antennal segments: 100:45:53:63:60:40:50:50:50:50:95. Segment 3 approximately 1.2 times as long as segment 2 and approximately 0.8 times as long as segment 4.

Prosternum moderately broad in the middle, strongly expanded apically, area between coxa flat or with shallow impression, without special sculpture, sides with rows of very small, setose punctures, expanded apex slightly convex, without special sculpture, with several small, hairy punctures.

Claws simple.

Host plants. Asteraceae : Brachylaena discolor DC ( Muir & Sharp 1904, Heron & Borowiec 1997, Heron 2003); Brachylaena elliptica (Thunberg) DC (H. Heron pers. comm.); Brachylaena uniflora Harvey (H. Heron pers. comm.).

Distribution. South Africa ( fig. 49 View FIGURE 49 ).

Remarks. A member of the Cassida unimaculata species–group.It differs from both relatives, C.drakensbergensis and C. emontinensis , in the round or broadly oval postscutellar black spot ( figs. 326, 327 View FIGURES 326–328 ) while in both relatives the spot is elongate or linear ( figs. 322 View FIGURES 322–323 , 324). Cassida drakensbergensis differs also in more impressed elytral punctures, in the anterolateral and central part of the elytra, partly marked with dark areolae (fig. 324). Cassida emontinensis looks very similar but differs in the postscutellar black spot very narrow, forming a stripe not extending behind the sutural border ( fig. 322 View FIGURES 322–323 ) and in the distinctly irregular surface of the explanate margin of elytra.

Type examined. Lectotype, designated by Borowiec, 1999: 290: [ SOUTH AFRICA]: Natal, Pt. Natal, Vahlberg ( NRS).
