Cephaloleia marginella   Uhmann. Blackwelder 1946: 719 (catalog); Uhmann 1950b: 336 (type), 1957a: 21 (catalog); Papp 1953: 19 (catalog); Gaedike and Döbler 1971: 353 (types); Wilcox 1983: 137 (catalog); Staines 1996: 43 (Central America species), 1997: 413 (Uhmann species list), 1999: 242 (mimicry); Staines and Staines 1997: 13 (types); McKenna and Farrell 2005: 119 (phylogeny), 2006: 10949 (phylogeny).


Elongate; subparallel; large; subdepressed; head black except yellow frons; pronotum yellow except black longitudinal medial vitta from base to apex, narrowest at base; elytra yellow with two black vittae; venter with abdominal sterna 1 and 2 yellow medially; legs with tibiae and tarsi dark. Head: vertex finely, sparsely punctate, medial sulcus absent; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; male with antennomere 3 triangular, ½ length of 1, 4 weakly triangular; female with 3 triangular, ½ length of 1, 4 cylindrical, elongate; 1 elongate; 2 transverse, ¼ length of 1; 5-10 transverse, decreasing in length; 11 pointed at apex, 2 × length of 10; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight then slightly narrowing to anterior angle, margined; anterior angle rounded; posterior angle angulate; anterior margin weakly emarginate behind head; disc flattened; surface impunctate; basal impression absent; pronotal length 1.0-1.3 mm; pronotal width 1.6-1.9 mm. Scutellum: elongate triangular; alutaceous. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, punctures obsolete at apex; row 1 weakly striate; declivity beginning just behind humerus at puncture row 7 not edged with faint carina; elytral length 5.0-5.7 mm; elytral width 2.1-2.4 mm. Venter: pro-, meso-, and metasterna extremely finely punctate, laterally each puncture with pale seta; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin emarginate in male, bisinuate in female. Leg: slender; impunctate; tibia with fringe of setae on inner margin of apex. Total length: 6.4-8.0 mm.


This species is similar to Cephaloleia apicata   . It can be distinguished by the lack of a declivity on the elytra beginning at puncture row 7 and by the yellow vitta on the lateral margins of the elytra.

Host plant.

Heliconia   sp. ( Heliconiaceae   ) ( Uhmann 1930a); adults have been collected on Caesalpinia eriostachys   Benth. ( Caesalpiniaceae   ) ( Staines 1996).
