Length: 8mm. Head (Fig. 34b): frontal setae extending beyond base of postpedicel; fronto-orbital plate gold, sparsely setulose throughout; parafacial color all silver; or mostly gold (75-90%); palps black. Thorax (Fig. 34a, c): gold on both dorsal and lateral surfaces; with four regular thoracic vittae; postpronotum with three setae; 3:3 acrostichal setae; 3:3 dorsocentral setae; 2:3 intra-alar setae; 2:3 supra-alar setae; three katepisternal setae; anatergite bare; scutellar discal setae slightly closer together than subapical scutellar setae, or absent. Wing vein R4+5 with at most 2-3 setulae dorsally at base, not extending to crossvein R-M. Abdomen (Fig. 34a): ground color dark brown-orange, with uninterrupted transverse marginal pollinose bands and T5 black apically; pollinosity gold dorsally, silver ventrally; base of ST1+2 black lateroventrally; T3 with one pair of median marginal setae and two pairs of discal setae; T4 with two pairs of discal setae. Terminalia: not examined. Female (Fig. 34d, e, f). Length: 6mm. As male, except for the following characters: fronto-orbital plate 1.41X as wide as in male; palps dark grayish-orange. Diagnosis Calolydella tenebrosa can be distinguished from all other species of Calolydella by the following combination of characters: frontal setae extending beyond base of postpedicel, palps black in males and dark grayish-orange in females, abdominal ground color dark brown-orange, anatergite bare, and abdominal T5 black apically in both sexes. Etymology The specific epithet Calolydella tenebrosa is derived from the Latin adjective "tenebrosum", meaning black or dark, in reference to the dark-colored palpi and dark-colored legs, character states found in both sexes of this species. Distribution Costa Rica, ACG, Alajuela and Guanacaste provinces, 320-380m. Ecology Calolydella tenebrosa has been reared once from Cyclophora Janzen14 and once from Semaeopus Janzen08 ( Lepidoptera : Geometridae ), in rain forest.
