Holotype male. Vic.: Goonmark Rocks scenic reserve, E. Gippsland, 16 Jan 1991, G. Theischinger. T-21509.

Paratype. Collected with holotype: T-21510, 1 male (illustrated).

Diagnosis. This species can be separated from other species of Caloca by the very narrow posterior half of segment X, which bears no spine-like setae, and the broad anterior half, which bears several dark spine-like setae on the dorsum.

Description. Adult male. Length of anterior wing: 6.5– 7 mm (n = 2). Head: postocular warts long, narrow, slightly broader dorsally; anterior setal warts rounded, raised, separated anteriorly, abutting posteriorly; a small, distinct, white puncture medially and anterior to anterior setal warts; a pair of large warts on frons anterior and medial to antennae. Antennae: slightly shorter than anterior wing length; scape about as long as pedicel and first two antennal segments combined, with relatively small projection on anterior surface arising from mid length and terminating just before distal margin of scape. Maxillary palpi: with long setae on dorsal surface of first three segments, last two segments with short setae. Pronotum: with one pair of large, distal setal warts and one pair of small medial setal warts. Forewing (fig. 26): forks 1 and 2 sessile, fork 3 petiolate, fork 4 absent; cross-veins s and r 4 -r 5 forming relatively straight line; cross-vein r-m angled medially from r 4 to r 5 at about 45°; cross-vein m absent, medial cell open; cross-vein m-cu distal from separation of Cu 1a and Cu 1b; cross-vein present between Cu 1a and Cu 1b; Cu 2 terminates at cross-vein between Cu 1b and A 1; vein A 1 terminates at wing margin slightly basad of Cu 2 termination point; small cross-vein present between A 1 and wing margin just distal to confluence of A 1 with A 2; nygma present in fork 2, absent in thyridial cell. Hindwing (fig. 27): Sc and R 1 fused almost along entire length until separating just before wing margin; fork 1 present on very short pedestal; fork 2 sessile, with nygma; M 1 and M 3 fused, basal section of M absent; Cu 1a and Cu 1a fused; Cu 2 absent; A 2 joins A 1 close to base of wing. Abdomen: segment 9 ventrally with distinct light patch, broad posteriorly and converging anteriorly before reaching anterior margin. Genitalia (figs 23–26): segment X anterior half broad, with several (8–10) strong, dark, posteriorly projecting spines on posterior half of dorsal surface and 3–4 strong, dark, posteriorly projecting spines on anterior half of ventral surface; posterior half slender, with two ridges slightly diverging posteriorly; preanal appendages slender, about as long as segment X; inferior appendages in lateral view broad, ventral surface rounded, dorsal surface somewhat straight; in ventral view apices directed medially, inner surface concave with large tapered spine subapically, ventral and dorsal margins with strong medially directed setae. Phallus: simple, slightly sclerotised on ventral and lateral surfaces, phallotremal sclerite present laterally at about three-quarters length.

Female and immature stages unknown.

Etymology. Named after the region of the type locality.
