Redescription. Measurements. Males: 7.4–7.9 mm, females: 9.2–11.0 mm.
Head and pronotum reddish, apices of mandibles black, antennae yellow with last one to three antennomeres black, legs yellow, often with outer sides of tibiae darkened, scutellum reddish, usually with darkened apical part, elytra yellow with black or metallic blue elytral margins, or elytra completely metallig green, ventral side of body yellow to reddish.
Male ( Fig. 22 View FIGURES 20 – 23 ). Labrum transverse, 2.45 times as wide as long, anterior margin widely rounded, surface subopaque, with 8 pale setae in transverse row. Anterior part of head finely punctate, lustrous, with several long pale setae along anterior margin and lateraly along antennal insertions. Interantennal space as wide as transverse diameter of antennal socket. Eyes large, interocular space narrow, 1.12 time as wide as transverse diameter of eye. Frontal tubercles large, subtriangular, with anterior tips divergent, surface impunctate, lustrous. Vertex distinctly impressed behind frontal tubercles, surface glabrous, covered with fine punctures. One setigerous pore with long pale seta placed behind inner posterior eye margin. Antennae thin, 0.75 times as long body, length ratio of antennomeres equals 22-10-19-23 -23-23-22-22-22-22-31.
Pronotum transverse, 2.20 times as broad as long, lustrous, moderately convex, widest at base, sparsely covered with large punctures and densely with very fine punctures. Anterior margin widely concave, lateral margins convergent and rounded anteriorly. All margins distinctly bordered. All angles swollen, with setigerous pores bearing long pale seta, additional short setae visible on lateral margins of pronotum. Scutellum subtriangular, with rounded tip, glabrous, covered with fine punctures.
Elytra 1.75 times as long as wide and 0.71 times as long as body, almost glabrous, with several short setae visible on lateral and apical slopes, covered with dense confused punctures. Humeral calli well developed. Epipleura wide basally, gradually narrowing posteriorly and disappearing before apex.
Anterior coxal cavities closed posteriorly. Last abdominal ventrite with two relatively deep incisions, median lobe with elongate oval impression, impression in middle of anterior half with sharp keel, penultimate ventrite with two triangular processes in middle of posterior margin separated by thin narrow incision, inner margins of both processes serrated, middle of anterior part of penultimate ventrite with cavity surrounded by sharp keel ( Fig. 11 View FIGURES 10 – 19 ).
Protarsomeres I and II subtriangular, protarsomere I 1.40 times as long as wide, length ratio of protarsomeres I–IV equals 7-5-6-6. Metatarsomere I long and narrow, length ratio of metatarsomeres I–IV equals 11-6-5-8. Claws appendiculate.
Aedeagus small, apex terminated with broad tip with rounded anterior margin. Dorsal process with apex bent down with two short sharp tips ( Fig. 10 View FIGURES 10 – 19 ).
Female ( Fig. 23 View FIGURES 20 – 23 ). Eyes smaller, interocular space wider, 1.50 time as wide as transverse diameter of eye. Antennae filiform, slightly thinner, shorter than in male, 0.55 times as long as body. Last ventrite with large Vshaped incision with or without rounded apex ( Figs 12–13 View FIGURES 10 – 19 ). Pygidium transverse, with posterior margin widely shallowly concave, tergite VIII pointed at apex or concave with small median tip ( Figs 14–15 View FIGURES 10 – 19 ). Sternite VIII with posterior margin nearly straight with small semicircular incision in middle, with short pale setae cummulated along anterior margin, tignum short, 0.75 times as long as sternite VIII ( Fig. 16 View FIGURES 10 – 19 ). Vaginal sclerite semicircular or elongate with trifurcate darker apex ( Figs 18–19 View FIGURES 10 – 19 ). Spermatheca as in Fig. 17 View FIGURES 10 – 19 .
Variability. Elytra in two different colourations: pale with black or metallic margins ( Fig. 22 View FIGURES 20 – 23 ) or completely metallic green ( Fig. 23 View FIGURES 20 – 23 ). I know only one transitional specimen mentioned already by Jacoby in original description which has brownish black elytra with distinctly darker margins. Population from Sumatra and Peninsular Malaysia slightly differ in several minor aspects: last ventrite in female either with large V-shaped incision with rounded apex (Peninsular Malaysia, Fig. 12 View FIGURES 10 – 19 ) or incision with sharp apex (Sumatra, Fig. 13 View FIGURES 10 – 19 ); tergite VIII rounded and pointed at apex (Peninsular Malaysia, Fig. 14 View FIGURES 10 – 19 ) or concave with small median tip (Sumatra, Fig. 15 View FIGURES 10 – 19 ); and shape of vaginal sclerite elongate (Peninsular Malaysia, Fig. 19 View FIGURES 10 – 19 ) or semicircular (Sumatra, Fig. 18 View FIGURES 10 – 19 ).
Distribution. Peninsular Malaysia ( Mohamedsaid 1994, 1995a, 1999a; Takizawa & Kimoto 2005, present study), Sumatra ( Jacoby 1884, Mohamedsaid 1994, present study), Borneo ( Mohamedsaid 1998a, 1999c, Mohamedsaid & Holloway 1999).
Differential diagnosis. Pale form of Coeligetes submetallica with yellow elytra surrounded with black margins cannot be confused with its congeners. The form with completely metallic elytra is similar to C. borneensis (see differential diagnosis under C. borneensis ).
Comments. The populations from Peninsular Malaysia (described as C. wilcoxi ) and Sumatra slightly differs in some minor aspects (see above). As the shapes of aedeagus are identical I treat both populations conspecific and C. wilcoxi is synonymized with C. submetallica .
Two females of C. submetallica deposited in ZMHB and collected in Soekaranda by Dohrn bear the cotype label. However, the true type material was collected by Dr. Hagen, thus these two specimens cannot be treated as type material of C. submetallica .
