All specimens were provided with an additional red printed label: ‘ HOLOTYPE [or PARATYPE respectively] ♀ | Chrysodema (Chrysodema) | holynskii sp. nov. | David Frank det. I. 2022 [date handwritten]’.

Description of holotype. Well preserved ♀ specimen with all appendages intact. Length 22.75 mm, width 8.25 mm, length/width ratio: 2.76.

Body navicular, head and elytra green-bronze, pronotum bronze; ventral side golden-green, legs green.

Head bronze-violet with green areas around eyes and at central part on dorsal side, green on ventral side. Eyes large, oval, area around eyes densely finely macropunctate. Frons bronze-violet with green central part, sparsely macropunctate and with short pubescence, 2× as wide as diameter of eye, impressed with deep medial sulcus. Vertex more densely macropunctate than frons. Micropunctures sparse on frons. Labrum brown, sparsely pubescent. Antennae serrate from antennomere IV. Antennomeres I and II bronze-violet with green reflections, sparsely macropunctate and pubescent; radicula and antennomeres from III dark brown with sparse long pubescence. Antennomere II ca. 3× shorter than I and III. Antennomeres IV–V long triangular, VI–X more trapezoidal than triangular, XI oval. Maxillae, labium, maxillary palpi and labial palpi dark brown, densely pubescent.

Pronotum trapezoidal, narrowing anteriad with rounded sides, black, moderately densely irregularly goldengreen macropunctate, sparsely micropunctate between macropunctures, 1.4× as wide as long, widest at half. Anterior margin arcuate, lobe not protruding, densely pubescent. Medial line without macropunctures, densely micropunctate. Medial and principal impressions only slightly indicated. Lateral impressions only at basal half, shallow, with several macropunctures. Lateral margin golden shiny. Basal margin moderately bisinuate.

Scutellum small, trapezoidal, bronze with green margins.

Elytra moderately wider than pronotum at base; parallel at basal half, narrowing from mid-length 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 5–10 macropunctures, arranged in almost regular rows. Areas between rows of groups of macropunctures sparsely micropunctate, at apical half appear as weak costae which are interconnected at short intervals, along suture a row of individual macropunctures. Most lateral interval coherently very densely macropunctate therefore almost entire area is golden-green and very shiny. Humeral calli moderately furrowed. Epipleura horizontal, broad at basal quarter, green with golden reflections, macropunctate and with short pubescence.

Legs metallic green with golden reflections; femora and tibiae macropunctate and pubescent more densely on inner side. Mesotibiae moderately curved at basal third and almost straight at two apical thirds ( Fig. 75 ). 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 very dense short pubescence. Prosternal process subparallel-sided, narrowed at apex, approximately 1.8× as long as wide, moderately densely and coarsely macropunctate at central part, apex and sides smooth,polished,nearly impunctate and sparsely pubescent.Metasternum macropunctate and pubescent. Abdominal ventrites densely macropunctate and pubescent at basal part,shiny with sparse macropunctures at apical part.

Variation. Body ♀♀ (n = 38): length: 21.50–29.50 (average 26.37) mm, width: 7.50–10.50 (average 9.42) mm, length/width ratio: 2.68–2.89 (average 2.80); male unknown. Colour of dorsal part from green-bronze to bronze, rarely green. Groups of macropuctures can be moderately variable but never large and always arranged in almost regular rows.

Differential diagnosis. Male of Chrysodema (C.) holynskii is unknown. Females of this species are the slenderest from whole group. Average length/width ratio is 2.80 in contrast to 2.60–2.72 of other species. Principal impressions of pronotum are only slightly indicated. Basic colour of elytra is green-bronze and not black. From subspecies of C. (C.) antennata can be distinguished by shiny and sparsely macropunctate apical part of abdominal ventrites, and from C. (C.) sekerkai by mesotibiae which are moderately curved at basal third and straight at two apical thirds. For additional characters see Key to species.

Etymology. This species is dedicated to my friend Roman B. Hołyński (Milanówek, Poland), a specialist in Buprestidae , mainly in subfamily Chrysochroinae .

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

Remarks. I studied three female specimens of C. (C.) holynskii labelled as types of Chrysodema coolsi . According to the description of Chrysodema (Thymedes) coolsi Hołyński, 1994 the type series includes one male (HT) and four female specimens. Two paratypes are deposited in IRSN, the holotype and two paratypes were in RHMP with Hołyński’s collection labels ‘BPeqp’ (HT), ‘BPeqo’ and ‘BPfke’. The paratype ‘BPfke’ has been sent to K. Akiyama (R. Hołyński pers. comm. September 2021). I studied two specimens from RHMP (BPeqp, BPeqo) and they certainly belong to the subgenus Thymedes . However, there are also three other female specimens in RHMP labelled as a holotype and paratypes of Chrysodema coolsi , det. R. Hołyński 1993 ( Fig. 53 ), with Hołyński’s collection labels ‘BPexd’ (HT) ( Fig. 52 ), ‘BPexe’ and ‘BPdi-’. These specimens are labelled erroneously and do not belong to the type series of Chrysodema (Thymedes) coolsi Hołyński, 1994 (R. Hołyński pers. comm. September 2021) or even to the subgenus Thymedes at all, evidently representing the new species of Chrysodema s.str. described hereby as Chrysodema (Chrysodema) holynskii sp. nov.
