Diagnosis. This species can be separated from other species of Caloca by the transparent ventral half of the inferior appendages, which gives them a concave appearance in ventral view.

Description. Adult male. Length of anterior wing: 5.5–5.6 mm (n = 3). Head: postocular setal warts long, narrow; a pair of large warts on frons anterior and medial to antennae. Maxillary palpi, with long setae dorsally. Antennae: shorter than anterior wing length; antennal scape about as long as first three antennal segments, with slender projection arising anteriorly at about mid length, extending to one-seventh scape length from anterior margin of scape. Pronotum: with one small pair of medial setal warts and one larger pair of distal setal warts. Forewing (fig. 21): discoidal and thyridial cells present; cross-vein between Sc and R 1; fork 1 sessile; fork 3 petiolate; vein Cu 2 weak; vein A 1 joins Cu 2 at arculus. Hindwing (fig. 22): vein R 1 and Sc fused along length until separating just before wing margin; fork 1 on small pedestal; fork 2 sessile. Abdomen: segment 9 ventrally with distinct light patch, broadly along midline for length of segment. Genitalia (figs 18–20): segment X in dorsal view broad basally, posterior three-quarters somewhat elongate and triangular, tapering distally; dorsolateral margins with row of six strong setae directed posterodistally; segment X ventrally with three pairs of strong setae in line with phallus, directed posteriorly; preanal appendages long, slender, extending almost length of segment X; inferior appendages somewhat short; in ventral view widely separated, medially with slightly projecting setose lobe, posterior half, from setose lobe to distal margin, transparent, giving medial margin of appendages a concave appearance; inner surface concave, with large posteromedially directed spine extending beyond posterior margin of each inferior appendage.

Female and immature stages unknown.

Etymology. From the Latin sica meaning ‘dagger’ and pertaining to the dagger-like segment X.
