Diagnosis. This species can be separated from other species of Caloca by the presence of a very broad, spine-like setule subapically on the ventral surfaces of each process of segment X.
Description. Adult male. Length of anterior wing: 5.8–7.2 mm (n = 5). Head: postocular setal warts long, narrow; anterior setal warts, raised and abutting; a pair of large warts on frons, anterior and medial to antennae. Maxillary palpi with medium length setae on dorsal surface. Antennae: about as long as forewing length; antennal scape about as long as first three antennal segments, with slender projection arising anteriorly in basal third, extending to anterior margin of scape, with dense tuft of setae between scape and projection. Pronotum: with one small pair of medial setal warts and one larger pair of distal setal warts. Forewing (fig. 36): discoidal and thyridial cells present; discoidal cell long; cross-vein between Sc and R 1; fork 1 sessile; fork 3 petiolate; vein A 1 joins Cu 2 at arculus. Hindwing (figs 37–39): discoidal cell, either small (fig. 37) or long (fig. 38), present in one or both of the hindwings, or absent (fig. 39); vein R 1 parallel to Sc until R 1 -R 2 cross-vein where they fuse for a short distance before separating to approach the wing margin; fork 1 either on small pedestal or sessile; fork 2 sessile; cross-vein present between M and Cu 1; base of M absent. Abdomen: segment 9 ventrally with distinct, triangular light patch; in lateral view rounded posteriorly and extended to reach around half length of segment X. Genitalia (figs 33– 35): segment X in dorsal view long and slender, deeply incised almost to base of segment; a large, broad spine-like seta subapically on lateral surface; a long, pale slender seta subapically on dorsal surface; a darker long, slender seta anterior to pale seta on dorsal surface; preanal appendages long, slender, extending to just beyond mid length of segment X; inferior appendages terminating just before length of segment X; in lateral view ventral margin relatively straight, dorsal margin with distinct, rounded rise above mid two-thirds, apically pointed; in ventral view broad, slightly converging towards posterior, apex rounded, inner apical margin with two small pointed teeth.
Female and immature stages unknown.
Etymology. From the Latin dispar meaning ‘imperfectly matched’ and ala meaning ‘wing’ and pertaining to the variation of the hindwings between and sometimes within specimens.
