Length: 7mm. Head (Fig. 6b): frontal setae extending to base of postpedicel; fronto-orbital plate gold throughout, ranging from bare to almost bare; parafacial silver throughout. Thorax (Fig. 6a, c): gold on dorsal surface, silver laterally (>50% coverage); vittae fused into two prominent dark stripes; postpronotum with three setae; 3:3 acrostichal setae; 2:3 dorsocentral setae; 1:3 intra-alar setae; 2:3 supra-alar setae; three katepisternal setae; anatergite with three or more hair-like setae, often in a small tuft; scutellar discal setae situated slightly closer together than subapical scutellar setae. Wing vein R4+5 with at most 2-3 setulae dorsally at base, not extending to crossvein R-M. Abdomen (Fig. 6a): ground color orange-yellow, with median dark stripe breaking up pollinose marginal banding; abdominal pollinosity gold dorsally, silver ventrally; base of ST1+2 black lateroventrally; T3 with a row of marginal setae and one pair of discal setae; T4 with one pair of discal setae. Male: not known at this time. Diagnosis Calolydella bicolor can be distinguished from all other species of Calolydella by the following combination of traits: fronto-orbital plate entirely gold, parafacial entirely silver, anatergite with three or more hair-like setae, and gold abdominal pollinose bands interrupted by a median dark stripe. Etymology The specific epithet is derived from the Latin adjective " bicolor ", meaning two-toned, in reference to its gold fronto-orbital plate and silver parafacial. Distribution Costa Rica, ACG, Guanacaste Province, Sendero Bernales , 660m. Ecology Calolydella bicolor has been reared once from Callicore lyca (Doubleday, 1847) ( Lepidoptera : Nymphalidae ), in rain forest.
