Diagnosis. This species can be separated from other species of Caloca by the 3–4 spines arranged laterally around the midpoint of segment X, and the apices of the inferior appendages being broadly incised.

Description. Adult male. Length of anterior wing: 5–5.7 mm (n = 4). Head: postocular warts long, relatively wide; anterior warts slightly raised, semicircular, abutting to form a circle; a pair of large warts on frons anterior and medial to antennae. Antennae: as long as anterior wing; scape approximately as long as depth of head capsule, with a process arising from the basal half and extending to the distal margin. Maxillary palpi: covered in setae, dorsal surface of first three segments with long setae; segments 4 and 5 about three-quarters length of other segments. Forewing (fig. 4): thyridial cell present; fork 3 petiolate; cross-vein m-cu between MP and Cu 1a distal to where MA and MP separate and where Cu 1a separates from Cu 1b; Cu 2 joins Cu 1b via cross-vein; A 1 joins Cu 2 at arculus. Hindwing (fig. 5): 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 short pedestal; fork 3 absent; veins M 1 and M 2 fused; basal section of vein M absent; vein Mp absent; Cu 1a and Cu 1b fused; Cu 2 absent. Genitalia (figs 1–3): segment X narrow, incised apically to about half length of segment, each apical projection with two or three long spines dorsally and one long spine ventrally at about the midpoint of segment; preanal appendages almost as long as segment X; inferior appendages, apices broadly incised with inner process stout, pointed and shorter than outer process; phallus in ventral view diamond-shaped apically.

Female and immature stages unknown.

Etymology. From the Latin ungula meaning ‘claw’ and pertaining to the claw-like inferior appendage.
