Derivation of name . From bi (Latin= two) plus colorata (Latin= color) for the two colors on the elytra. Diagnosis . This species is in group 5b ( Uhmann 1937 ). It can be distinguished from other members of species group 5b by antennomere I being transverse, the pronotal impression being present, the elytra having the lateral and apical margins serrate, and the yellow pronotum and the metallic blue elytra with apical fourth yellow. Description . Head, pronotum and apical 1/4 of elytra yellowish, rest of elytra dark metallic blue; antennae black; legs black with profemora bicolored. Head: medial sulcus becoming carina before base of antennae; vertex alutaceous; frons projecting. Antenna: antennomere I cylindrical, pale at base; II transverse; III­X cylindrical; II and III subequal in length, others decreasing in length; XI pointed at apex; I­IV glabrous; V­XI setose. Pronotum: lateral margin straight and slightly divergent for basal, then rounded and strongly convergent to apex; tooth present in each anterior angle; disc convex, punctate laterally, nearly impunctate medially, with anterior margin rugose; moderate basal impression present; width greatest at base; pronotal length 1.1 mm ; pronotal width 1.7 mm . Scutellum: quadrate; alutaceous. Elytron: lateral and apical margins serrate; four costae present, 2nd and 4th most pronounced, 1st and 3rd visible at base and apex; with 10 complete punctures rows; elytral length 5.9 mm ; elytral width 2.4 mm . Venter: prosternum yellow, with few punctures anterior to coxae; mesosternum yellow, diffuse black laterally, punctate; metasternum black, punctate; abdominal sterna dark, punctate medially, alutaceous laterally. Leg: femur with a few long golden setae grouped together on inner margin; tibia with golden setae on inner margin and tuft of golden setae at apex. Total length: 7.9 mm . Variation. Specimens vary in pronotal length from 1.0­ 1.1 mm , in pronotal width from 1.6­1.7 mm , in elytral length from 5.6­5.9 mm , in elytral width from 2.3­2.4 mm , and total length from 7.7­8.0 mm. The color and sculpture is very similar to that of the holotype . Notes . Taken on the undersides of leaves of Sterculia recordiana papyracea E. Taylor (Sterculiaceae) .
