Description
Elongate-oval; subconvex; head metallic olive-green with bluish-violet reflection; antennae (except basal antennomere rust-colored) black; pronotum yellow (in dry specimens) to pink (in live specimens) with medial black triangular marking from base to apex; scutellum olive-green; elytra brownish or yellow with broad olive-green marking from base to apex from suture to puncture row 7; venter diffuse brownish-black medially, yellowish laterally; legs black on upper surface, yellowish on lower surface. Head: vertex densely, coarsely punctate, punctures tend to for short striae, medial sulcus faint; frons impunctate, not projecting; depressed between eyes. Antenna: reaches beyond humerus; slender; antennomeres 1–2 elongate, cylindrical, subequal in length, each ½ length of 3; 3 elongate, cylindrical; 4–10 cylindrical, decreasing in length; 11 2× length of 10, rounded at apex; 1–2 punctate with scattered setae; 3–11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle (some specimens regularly arcuate), slightly explanate, margined; anterior angle broadly rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface irregularly foveolate-punctate, punctures finer on disc; transverse basal impression present medially; pronotal length 1.0–1.4 mm; pronotal width 1.5–2.0 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, slightly serrate, margined; apical margin rounded, serrate; sutural angle emarginate, without tooth; humerus broadly rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, punctures slightly foveolate, additional row of punctures present between puncture rows 7 and 8 after middle, row 10 removed from lateral margin, rows converge and unite apically, rows 7 and 8 confused; elytral length 4.7–5.2 mm; elytral width 2.4–3.1 mm. Venter: prosternum rugose medially, punctate laterally; meso- and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite weakly emarginate in male, deeply emarginate in female. Leg: robust; coxa, femur, and tibia punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.5–6.9 mm.
Diagnosis
This species is similar to Cephaloleia irregularis. It can be distinguished by the regular elytral punctation, and by the additional row of elytral punctures.
Host plant
Elleanthus cf. robustus (Rchb. f.) Rchb. f., Elleanthus sp., Epidendrum werklei Schltr., Oerstedella exasperata (Rchb. f.) Hágsater, and Oerstedella wallisii (Rchb. f.) Hágsater (Orchideaceae) (Sekerka et al. 2013[1]).
Immatures
Color when live is white with outer margins translucent, with one or two elongate darker areas on pronotum and last abdominal segment, two pinkish longitudinal stripes from pronotum to abdominal segment 6 (Figs 53–54). Dorsum shallowly rugose, with medial non-setose ridge from anterior to posterior margin. Pronotum raised medially at base, surface shallowly rugose and with sparse microsetae; with medial diagonal carina anteriorly; lateral margins rugose, terminating in membranous fringe. Meso- and metanota elevated medially; shallowly rugose with sparse microsetae. Abdominal tergites 1–8 without carinae, shallowly rugose with sparse microsetae. Spiracles annular with crenulate peritreme. Tergites 9–10 without spiracle, rounded apically.Venter with surface expansions smooth to shallowly tuberculate. Head with surface smooth with five large and one small stemmata on each side; clypeus with surface smooth, basally with four long, stout setae and apically with margins densely fringed with unequal short robust setae; maxially palps with 2 palpomeres, basal palpomere with two setae, apical palpomere with one lateral seta and terminating with 11 short setae; maxilla robust, clavate, with two stout setae at base of palpomere and fringes with unequal setae apically; labrium densely setose; labial palp with one palpomere with eight setae apically; mandibles shallowly quadridentate. Antenna with 3 antennomeres; antennomere 3 with one long, stout concial seta and eight short setae. Sternal and abdominal segments shorter than wide; surface smooth, concave. Leg: femur wider and shorter than tibiotarsus; tibiotarsus subconical, with stout claw and ten setae at apex. Total length 7.9 mm; width 4.4 mm. (Sekerka et al. 2013[1]).
