Description

Male (Fig. 9a, b, c). Length: 6mm. Head (Fig. 9b): frontal setae extending to base of postpedicel; fronto-orbital plate entirely gold, and sparsely setulose only along upper half; parafacial silver. Thorax: (Fig. 9a, c) gold on both dorsal and lateral surfaces; thorax with four vittae visible only under certain angles of light; 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 absent. Wing vein R4+5 with 3-4 setulae dorsally at base. Abdomen (Fig. 9a): ground color black, with thin median dark stripe breaking up pollinose marginal banding; abdominal pollinosity gold dorsally, silver ventrally; 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. Terminalia (Fig. 10): sternite 5 (Fig. 10c) with two small lobes and a wide U-shaped median cleft, 0.39X the length of the sternite from lobe to apex; inner margin covered by dense pollinosity, appearing darker than surrounding cuticle; upper margin of sternite with many stout, outwardly-pointing setae. Cerci (Fig. 10b) separated by a narrow gap basally, widening to an oval about midway; cercus, in dorsal view, long and rounded and not significantly tapering from base to tip; cercus, in lateral view, straight and setose along basal half, with a slight bulb at its tip. Surstylus (Fig. 10a) short, 2/3 length of cercus, and knife-like, appearing sharply pointed when viewed laterally; apical half of surstylus with short setae; tip of surstylus slightly angled outwards when viewed dorsally.

Female: not known at this time.

Diagnosis

Calolydella crocata can be distinguished from all other species of Calolydella by the following combination of traits: fronto-orbital plate mostly gold-pollinose but with some silver pollinosity and sparsely setulose, thorax with four vittae visible only under certain angles of light, anatergite bare, and abdomen with transverse marginal pollinose bands interrupted by a thin dark median stripe.

Etymology

The specific epithet is derived from the Latin adjective "crocatum", meaning yellow, in reference to the gold pollinosity present over most of the body of the new species.

Distribution

Costa Rica, ACG, Guanacaste Province, Estación Quica, 470m.

Ecology

Calolydella crocata has been reared once from Semaeopus Janzen05 ( Lepidoptera : Geometridae ), in rain forest.
