Description of holotype. Well preserved ♂ specimen with all appendages intact, only both fore legs are glued in femoro-tibial joints. Length 23.50 mm, width 8.50 mm, length/width ratio: 2.76.

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

Head black with green punctures on dorsal side, green on ventral side. Eyes large, oval, area around eyes densely finely macropunctate with green macro punctures and sparsely pubescent. Frons black, sparsely macropunctate with green macropunctures, 2× as wide as diameter of eye, impressed with deep medial sulcus, with sparse short pubescence. Vertex more coarsely macropunctate than frons. Micropunctures almost absent. Labrum brown, with long pubescence. Antennae serrate from antennomere IV. Antennomeres I and II green with coppery reflections, sparsely macropunctate and pubescent; radicula and antennomeres from III dark brown with sparse long pubescence. Antennomere II ca. 4× shorter than I and III. Antennomere IV long triangular, V–X more trapezoidal than triangular, XI oval. Maxillae, labium, maxillary palpi and labial palpi brown, densely pubescent.

Pronotum trapezoidal, narrowing anteriad with rounded sides, widest at mid-length, black, moderately densely irregularly golden-green macropunctate, 1.5× as wide as long. Micropunctures almost absent. Anterior margin arcuate, lobe not protruding, densely pubescent. Medial line very weak, almost coalesces with pattern of disc, without medial impressions. Principal impressions oval, golden-green, densely macropunctate. Lateral impressions moderately deep, with several macropunctures. Lateral margin golden shiny. Basal margin moderately bisinuate.

Scutellum small, trapezoidal, green with golden reflections.

Elytra moderately wider than pronotum at base; subparallel in basal half, narrowing from beyond its midlength to apex; convex in lateral view. Lateral margins arcuate below humeral calli, serrate at apical third. Groups of macropunctures of almost the same size contain ca 5–10 macropunctures, 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 a row of individual macropunctures. Micropunctures almost absent. Last two lateral intervals coherently very densely macropunctate therefore almost entire area is green with golden reflections, golden spot behind humeral calli from base. Humeral calli moderately furrowed. Epipleura horizontal, broad at basal quarter, green with golden reflections, moderately densely macropunctate and sparsely pubescent.

Legs metallic green with golden reflections; femora and tibiae macropunctate and pubescent more densely on inner side. Inner side of mesotibiae from middle to tarsi with very dense and long pubescence. Tibiae with two apical ventral spurs. Tarsi metallic green, tarsal claws divergent and simple.

Ventral side metallic green with golden reflections. Hypomeron irregularly macropunctate more densely than prosternum. Anterior margin of prosternum with dense short pubescence. Prosternal process subparallel-sided, narrowed at apex, approximately 1.9× 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 densely macropunctate and pubescent. Inner apical margin of metasternum with dense long pubescence. Abdominal ventrites I–V centrally less, laterally more densely macropunctate in entire width, densely pubescent. Metallic green and pubescent area of abdominal sternite IX arcuately bordered at base ( Fig. 79 ).

Aedeagus. Narrowly regularly navicular, widest at mid-length, length: 6.09 mm, width: 1.09 mm, length/ width ratio: 5.59. Parameres open from mid-length, apices of parameres rounded. Penis subparallel-sided, deeply impressed with densely arranged striate laminae at entire width, apex of penis narrowly triangular ( Fig. 72 ).

Variation. Body ♂♂ (n = 4) length: (20.75)23.00– 23.50 mm, width: (7.50) 8.50–8.75 mm, length/width ratio: (2.63)2.74–2.77; ♀♀ (n = 35): length: 24.25–30.00(31.50) (average 27.09) mm, width: 9.00–12.00 (average 10.12) mm, length/width ratio: 2.50–2.82 (average 2.68). Groups of macropuctures can be variable but never large. Colour of macropunctures variable from green to dark green-brown. Aedeagus (n = 5) length: 5.54–6.09 mm, width: 1.00– 1.14 mm, length/width ratio: 5.26–5.59.

Differential diagnosis. Males of all subspecies of C. (C.) antennata have very dense and long pubescence on inner side of mesotibiae from middle to tarsi. Males of C. (C.) antennata barriesi have antennae shorter than pronotum. From C. (C.) antennata antennata can be distinguished by shape of penis which is subparallel-sided and by rounded border of metallic green area of male abdominal sternite IX ( Fig. 79 ). From C. (C.) antennata obsoleta can be distinguished by parameres which are open from middle ( Fig. 72 ) and also by arcuate border of metallic green area of male abdominal sternite IX. For additional characters see Key to species.

Etymology. This species is named after Wolfgang Barries (Vienna, Austria), a specialist in Buprestidae , mainly in the genus Chrysobothris , who kindly provided the holotype specimen.

Distribution. Philippines: Palawan Island ( Fig. 62 ).
