Description

Female (Fig. 4a, b, c). Length: 6mm. Head (Fig. 4b): frontal setae extending to base of postpedicel; fronto-orbital plate all silver, sparsely setulose throughout; parafacial silver throughout. Thorax (Fig. 4a, c): silver pollinose on both dorsal and lateral surfaces; with four regular thoracic vittae; postpronotum with three setae; 3:3 acrostichal setae; 2:3 dorsocentral setae; 2:3 intra-alar setae; 2:3 supra-alar setae; three katepisternal setae; anatergite with three or more setae, often in a small tuft; scutellar discal setae situated slightly wider apart than subapical scutellar setae. Wing vein R4+5 with 6-7 setulae dorsally, reaching from base almost to crossvein R-M. Abdomen (Fig. 4a): ground color black with uninterrupted transverse marginal pollinose bands covering anterior marginal 2/3 of tergites; both abdominal surfaces (dorsal and ventral) concolorous; base of ST1+2 black lateroventrally; T3 with one pair of median marginal setae and one pair of discal setae; T4 with one pair of discal setae.

Male: not known at this time.

Diagnosis

Calolydella argentea can be distinguished from all other species of Calolydella by the following combination of traits: parafacial and fronto-orbital plate entirely silver, frontal setae extending to base of postpedicel with intermingled small setulae, 3:3 acrostichal setae, anterior 2/3 of abdominal tergites with silver pollinose bands, anatergite with three or more hair-like setae, and wing vein R4+5 with 6-7 setulae, almost reaching to crossvein R-M.

Etymology

The specific epithet is derived from the Latin adjective "argentum", meaning silver, in reference to its entirely silver parafacial and fronto-orbital plate, a feature unique to this species.

Distribution

Costa Rica, ACG, Alajuela Province, Finca Esmeralda, 123m.

Ecology

Calolydella argentea has been reared once from Antiblemma Poole33 ( Lepidoptera : Noctuidae ), in rain forest.
