Diagnosis
. Small, wedge-shaped, regularly convex and semi-matt species (
Figs. 1
,
7, 8
); dorsal side dark golden green with brass lustre, frons and antennae green, pronotum with brown medial spot reaching both anterior and posterior pronotal margins; lateral elytral margins with red lustre, legs dark golden green; ventral surface black, only prosternal process green; entire body completely asetose.
Description of
holotype
.
Head wide, vertex 3.5 times as wide as width of eye, slightly convex; frons regularly and shallowly concave forming very fine carina along inner margins of eyes; frontoclypeus delta-shaped with nearly straight anterior margin; eyes relatively large, slightly reniform, not projecting beyond outline of head; sculpture of head consisting of dense, fine microsculpture and small and sparse, simple punctures; antennae short reaching only anterior third of pronotal margins; basal two antennomeres swollen, scapus slightly curved, pear-shaped, twice as long as wide, pedicel short, elliptical, only slightly longer than wide; 3
rd
antennomere nearly twice as long as wide, 4
th
antennomere slightly longer than wide, 5
th
antennomere nearly spherical; antennomeres 6–10 widely trapezoid, 1.8 times as wide as long, terminal antennomere rhomboid.
Pronotum 2.1 times as wide as long, regularly convex, only slightly flattened along lateral sides; anterior pronotal margin with wide and large medial lobe, posterior margin deeply bisinuous; lateral margins very feebely denticulate, regularly rounded in anterior two thirds and almost straight in posterior third; anterior pronotal angles narrowly, posterior angles widely rounded; pronotal sculpture consisting of very fine basal microsculpture and rather sparse, simple punctures which
form very
fine, transverse wrinkles on pronotal disc. Scutellum relatively large, widely triangular, nearly twice as wide as long, microsculptured.
Elytra 1.8 times as long as wide, slightly wedge-shaped and regularly convex; humeral swellings small, basal, transverse depression missing, each elytron narrowly and separately rounded; apical parts of elytral margins very finely serrate; epipleura well-developed but not reaching elytral apex; elytral sculpture consisting of very fine microsculpture and dense, simple but rather wide punctures.
Ventral surface lustrous with fine and sparse, simple punctures, anal ventrite widely rounded apically with narrow, transverse preapical depression (
Fig. 4
). Legs short, metafemora conspicuously swollen, metatibiae somewhat flattened with small, external, preapical emargination and comb-like row of pale bristles (
Fig. 6
). Tarsomeres 1–4 with well-developed adhesive pads, claws with large and obtuse basal tooth.
Aedeagus (
Fig. 2
) flattened, parameres strongly widened apically with broadly rounded tips; medial lobe robust, slightly enlarged apically, with widely bilobed apex.
Sexual dimorphism
. Female differs from male only by dark bronze coloration, more widely rounded anal ventrite with larger preapical depression and by distinctly shorter antennae.
Measurements
. Length: 3.3–3.4 mm (
holotype
3.3 mm); width: 1.5–1.6 mm (
holotype
1.5 mm).
Variability
. Only a minimum variability in size was observed (see “
Measurements
”). One male
paratype
possesses nearly golden green dorsal coloration; metallic coloration of prosternal process varies from golden green to bronze.
Bionomy
. Larvae of
E. biakensis
gen.
nov., sp. nov.
are leaf-miners on
Macaranga
sp. (Euphorbiaceae)
(
Fig. 9
). Adult beetles gathered on sun-exposed leaves on upper part of the host plant. Infested leaves contained 2–12 mines each; unfortunately only old, empty mines were found so the larva is still unknown.
Etymology
. This species was named after the
type
locality (Biak island).
Differential diagnosis

Endelomorphus
gen. nov.
