Description of holotype. Well preserved ♂ specimen, missing only last left hind tarsomere. Length 24.75 mm, width 9.00 mm, length/width ratio: 2.75.
Body generally bright metallic green with golden reflections. Ventral pads on all tarsomeres dorsally brownishblack. Antennae black, basal two antennomeres metallic green. Labrum, labium and maxillae pale brown. Ventral side strongly shiny, bright metallic green, centrally golden-copper.
Head moderately densely punctate, punctures foveolate, each bearing short seta, thus frons sparsely pubescent. Vertex more densely punctate and punctures bearing adherent setae.
Pronotum densely macropunctate, shiny parts moderately densely micropunctate and distinctly micro-reticulate, thus not strongly shiny. Macropunctation laterally gradually coarser and denser, thus the structure is strongly rugose. Each macropuncture bearing moderately long white adherent seta. Medial line more or less visible, sparsely micropunctate, without macropunctures, flat. Medial impressions indistinct. Principal impressions moderately large, oval, relatively deep; internally with more or less visible stripe of small and dense punctures. Lateral impressions shallow, with several more or less visible macropunctures and indistinct micropunctures. Lateral margin carinate in basal 4/5, then widening and flattened and reaching almost to anterior margin of pronotum.
Elytra regularly convex with slight postscutellar hump, bearing distinctly elevated sharp and moderately broad costae along suture and on intervals 2, 4, 6 and 8. Interval 2 distinctly curved on apical third. Interval 6 shortened, reaching to 1/2 length of elytra, then interrupted, before continuing for short distance as isolated branch laterally connected to interval 4. Costae moderately densely micropunctate (at magnification 50 ×) and each with a few additional confusedly dispersed macropunctures. Intercostal depressions deep and moderately densely macropunctate. Punctation completely irregular, but partly with tendency to form small groups of punctures, which appear like larger puncture and particularly visible on basal half of elytra. Each macropuncture bearing short adherent white seta, but impressions do not appear pilose. Interspaces at maximum 2 × as wide as puncture diameter but mostly as wide as puncture diameter.
Epipleura in basal 1/4 broad, sparsely and moderately punctate, then abruptly constricted with obtusely angled corner and then gradually narrowing apically; punctures becoming finer and vanishing towards apex. Each puncture bearing long erect white seta.
Fore and mid femora in central part strongly shiny, sparsely punctate; hind femora somewhat more densely punctate. Each puncture bearing seta, setation particularly conspicuous on lower side of hind femora.
Ventral side of body (Fig. 59) overall densely and moderately coarsely punctate only central part sparsely punctate with large shiny impunctate areas. Entire lateral sides of all abdominal ventrites densely and almost uniformly punctate, only towards external margins punctation finer but even denser (Fig. 60).
Aedeagus length: 8.56 mm, width: 1.61 mm, length/width ratio: 5.32. Parameres elongate-rhomboidal in outline, apices moderately broad and subtruncate. Apex of penis strongly narrowed and projecting beyond parameres. Penis ventrally deeply concave without striate laminae (Fig. 84). Ventrite VIII impressed and very densely pubescent (Fig. 89).
Variation. Body ♀♀ (n=7): length: 27.00– 31.25 mm, width: 10.25–11.50 mm, length/width ratio: (2.63)2.70– 2.72. Slightly variable species. Colouration as in holotype, just one specimen with predominantly copper dorsum. Structure of elytra constant only third costa interrupted to complete. Pronotum of variable shape and structure; most specimens with trapezoidal pronotum, but one with subquadrate. Punctation of pronotum can be either slightly sparser and finer than in holotype or somewhat denser and coarser. Principal impressions shallow to moderately deep.
Differential diagnosis. Chrysodema (C.) gottwaldi sp. nov. is externally quite similar to C. (C.) dohrnii because of green dorsum and to C. (C.) fuscitarsis due to dense pubescence of elytra. However, it has entirely different morphology of the male genitalia with parameres elongate (vs. broadly rhomboidal), ventral side of penis with smooth and deep concavity (vs. slightly impressed with numerous laminae), and apex of penis narrowly pointed and projecting beyond parameres (vs. broadly triangular and barely projecting beyond parameres. Chrysodema (C.) gottwaldi sp. nov. is sympatric with C. (C.) fuscitarsis but can be distinguished by green colour (vs. brown-bronze) and sparsely pubescent lateral sides of pronotum (vs. densely pubescent). See also Table 3 on page 49.
Etymology. This species epithet is dedicated to Stephan Gottwald (Berlin, Germany), specialist in the Buprestidae, who kindly provided the holotype specimen.
Distribution. Philippines, Palawan Province, Palawan Island.
Remarks. Colour photographs of this species were already published by Akiyama & Ohmomo (2000: Pl. 46, Figs 485-1, 485-2) under the name C. (C.) fairmairei and by Lander (2003: 78, Fig. 66) as C. (C.) mniszechii. We have studied the specimen illustrated by Lander, which is here designated as paratype of C. (C.) gottwaldi sp. nov. Based on external characters shown in the photograph we are convinced that also the specimen illustrated by Akiyama & Ohmomo (2000) belongs to C. (C.) gottwaldi sp. nov. but we did not study the specimen.
