Description

Male (Fig. 23a, b, c). Length: 8mm. Head (Fig. 23b): frontal setae extending to base of postpedicel; fronto-orbital plate gold, ranging from bare to almost bare; parafacial silver along lower half. Thorax (Fig. 23a, c): gold on dorsal surface, silver laterally (>50% coverage); with two bold thoracic vittae; postpronotum with three setae; 2:3 acrostichal setae; 2:3 dorsocentral setae; 2:3 intra-alar setae; 1:3 supra-alar setae; three katepisternal setae; anatergite with three or more hair-like setae, often in a small tuft; scutellar discal setae slightly closer together than subapical scutellar setae. Wing vein R4+5 with 2-4 setulae dorsally, confined to base of wing vein, not extending up to crossvein R-M. Abdomen (Fig. 23a): ground color dark orange, with a median dark stripe breaking up pollinose marginal banding; abdominal pollinosity gold dorsally, silver ventrally; base of ST1+2 black lateroventrally, mostly gold pollinose dorsally; T3 with a row of marginal setae and one pair of discal setae; T4 with one pair of discal setae. Terminalia: not examined.

Female (Fig. 23d, e, f). Length: 6mm. Fronto-orbital plate 2X as wide as in male.

Diagnosis

Calolydella interrupta can be distinguished from all other species of Calolydella by the following combination of traits: parafacial at least 50% silver pollinose, two bold thoracic vittae, abdominal pollinosity interrupted by median stripe, anatergite with three or more setae arranged in a small tuft, and T3 with a complete row of marginal setae.

Etymology

The specific epithet is derived from the Latin adjective "interruptum", meaning breach or interruption, in reference to dark median stripe breaking up the gold marginal pollinosity on the abdomen of this species.

Distribution

Costa Rica, ACG, Guanacaste Province, Sendero Arenales 1080m.

Ecology

Calolydella interrupta has been reared once from Acharia ophelians (Dyar, 1927) ( Lepidoptera : Limacodidae ), in cloud forest.
