Description of holotype. Well preserved ♂ specimen with all appendages, only one of claws on left fore leg and last antennomere of right antenna are missing. Length 22.75 mm, width 8.25 mm, length/width ratio: 2.76.

Body navicular, basic colour of dorsal side black but it seems dark green because of dense metallic green punctures; ventral side green with golden reflections, legs green.

Head black with green punctures, green on ventral side. Eyes large, oval, area around eyes with dense fine green macropunctures and sparsely pubescent. Frons black, with sparse green macropunctures, 2.1× as wide as diameter of eye, impressed with deep medial sulcus, with sparse short pubescence. Labrum dark brown, with long pubescence.Antennae longer than pronotum, serrate from antennomere IV. Antennomere I green, II bronze, sparsely macropunctate and pubescent; radicula and antennomeres from III dark brown with long pubescence. Antennomere II ca. 4× shorter than I and III. Antennomeres IV–X long triangular, XI oval. Maxillae, labium, maxillary palpi and labial palpi brown, densely pubescent.

Pronotum trapezoidal, narrowing anteriad with rounded sides, black, moderately densely irregularly goldengreen macropunctate, 1.4× as wide as long, widest at mid-length. Anterior margin arcuate, lobe not protruding, densely pubescent. Medial line visible, interrupted at centre, without medial impressions. Principal impressions oval, golden-green, densely macropunctate. Lateral impressions moderately deep, densely macropunctate. Lateral margin green, shiny. Basal margin moderately bisinuate.

Scutellum small, trapezoidal, green with golden reflections.

Elytra moderately wider than pronotum at base; subparallel at basal half, narrowing from beyond its midlength to apex, strongly convex in lateral view. Lateral margins arcuate below humeral calli, serrate at apical third. Groups of macropunctures of almost the same size contain ca 3–8 macropunctures, larger on lateral parts, arranged in almost regular rows. Black areas between rows of groups of macropunctures appear as weak costae which are interconnected at short intervals, along suture golden-green stripes with individual macropunctures. Last two lateral intervals coherently very densely macropunctate therefore almost entire area is green with golden reflections. Humeral calli golden-green, densely macropunctate. Epipleura horizontal, broad at basal third, green with golden reflections, moderately densely macropunctate and pubescent.

Legs metallic green with golden reflections; femora and tibiae macropunctate and pubescent more densely on inner side. Mesotibiae curved at apical third and strongly bent at basal third, without long pubescence at basal third. Tibiae with two apical ventral spurs. Tarsi metallic green, tarsal claws divergent and simple.

Ventral side metallic green with golden reflections. Hypomeron and prosternum macropunctate and with short pubescence. Anterior margin of prosternum with dense short pubescence. Prosternal process subparallel-sided, narrowed at apex, approximately 2× as long as wide, moderately densely and coarsely macropunctate at central part, macropunctures bigger than macropunctures on prosternum, apex and sides smooth, polished, nearly impunctate and sparsely pubescent. Metasternum sparsely finely punctate and shiny at central part; more densely on sides, pubescent. Abdominal ventrites I–III moderately densely punctate at central part, laterally more densely punctate, pubescent. Abdominal ventrites IV–V more densely punctate than I–III at central part.

Aedeagus. Broadly rhomboidal, widest at mid-length, length: 6.14 mm, width: 1.41 mm, length/width ratio: 4.35. Parameres narrowly open at apex, apices of parameres rounded ( Fig. 68 ).

Variation. Body ♂♂ (n = 5) length: 20.00–22.75 (average 21.50) mm, width: 7.50–8.25 (average 7.95) mm, length/width ratio: 2.67–2.76 (average 2.71); ♀♀ (n = 129): length: 22.00–30.50 (average 26.44) mm, width: 8.25– 11.75 (average 10.16) mm, length/width ratio: 2.51–2.74 (average 2.60). Groups of macropuctures can be variable but never large. Colour of macropunctures variable from golden-green to dark green-brown, very rare dark brown. Aedeagus (n = 4) length: 5.82–6.14 mm, width: 1.36–1.41 mm, length/width ratio: 4.28–4.48.

Differential diagnosis. Males of C. (C.) sekerkai have antennae longer than pronotum, broadly rhomboidal aedeagus and strongly bent basal third of mesotibiae without long pubescence. Females can be distinguished by bent basal third of mesotibiae ( Fig. 74 ) and from C. (C.) holynskii also by black basic colour of elytra between groups of macropunctures. Macropunctures on pronotum generally coarser than in C. (C.) antennata obsoleta and with golden-green margin. For additional characters see Key to species.

Etymology. This species is dedicated to my good friend Lukáš Sekerka (Prague, Czech Republic), a wellknown specialist in world Cassidinae and Hispinae (Chrysomelidae) ... and now also in Buprestidae .

Distribution. Indonesia: Banggai, Potil-Kecil, Peleng and Sulawesi islands ( Fig. 62 ).

Remarks. I studied five specimens deposited in IRSN and RHMP labelled as holotype and paratypes of ‘ Chrysodema grootaerti Hołyński’. This name has never been published (R. Hołyński pers. comm. September 2021) and all specimens belong to the C. (C.) sekerkai sp. nov.
