Diagnosis. This species can be separated from other species of Caloca by the shape of segment X, which in dorsal view is broad at the anterior margin, expanding out laterally towards the posterior until the midpoint, where the lateral margins are rounded and gradually converge to a posterior point.

Description. Adult male. Length of anterior wing: 6.5–6.8 mm (n = 2). Head: postocular setal warts long, narrow; anterior setal warts abutting; a pair of large warts on frons anterior and medial to antennae. Maxillary palpi (broken in both specimens), first three segments with dense, long setae dorsally. Antennae: broken in both specimens; antennal scape about as long as first three antennal segments, with slender projection arising anteriorly at about mid length, extending to anterior margin of scape. Pronotum: with one small pair of medial setal warts and one larger pair of distal setal warts. Forewing (fig. 31): discoidal and thyridial cells present; cross-vein between Sc and R 1; fork 1 sessile; fork 3 petiolate; vein A 1 joins Cu 2 at arculus; cross-vein between A and wing margin present at confluence of A 1 and A 2+3. Hindwing (fig. 32): vein R 1 parallel to Sc until just beyond midpoint of wing where they fuse for a short distance before separating to approach the wing margin; fork 1 on small pedestal; fork 2 sessile; cross-vein present between M and Cu 1. Abdomen: segment 9 ventrally with distinct light patch, broadly along midline for length of segment. Genitalia (figs 28–30): segment X in dorsal view basally broad, rapidly expanding laterally towards posterior until the midpoint, then gradually tapering to point, with a distinct ridge along midline and lesser ridges to either side, lateral margins rounded with row of strong posterolaterally and laterally directed spines, with a pair of posteriorly directed spines on dorsum at about the midpoint, posterior one-sixth narrowly incised; preanal appendages long, slender, extending just beyond length of segment X; inferior appendages about as long as segment X; in lateral view apical quarter sharply upturned, terminating in a dorsally directed point.

Female and immature stages unknown.

Etymology. Named after the type locality.
