Diagnosis. In facies, C. angulata is similar to C. castanescens and C. rubigo , but its genitalia indicate it is more closely related to C. potosiana . The male genitalia of C. angulata differ from those of its congeners in having a distinct, pointed angle of the sacculus and a sharp termination of the socius.

Description. Wing span ca 18 mm. Male: Head cream, thorax more brownish. Forewing rather slender; costal fold to middle; termen distinctly concave medialy. Ground colour cream, suffused yellowish brown except for postmedian patch and ocellar area; ocellus with fine blackish inner lines; terminal area cinnamon brown; strigulation brownish. Markings pale ferruginous; basal blotch atrophied; median fascia pale cinnamon brown, concolorous with costal divisions. Cilia paler than markings. Hindwing cream brown; cilia creamer. Genitalia ( Fig. 4 ) with uncus very broad, short, convex; socius broad, tapering terminad with small apical prominence; angle of sacculus short; neck of valva very short, slender; cucullus with broad ventral lobe and uniformly convex caudal edge; aedeagus with terminal thorn. Female: Unknown.

Holotype male: " Mexico: Chiapas, San Cristobal de las Casas, 2300 m, 23–27.VI.1981, V.O. Becker Col; Col. Becker 43774"; GS 842 WZ. Two male paratypes with identical label data.

Etymology. The specific epithet refers to the angle of the sacculus; Latin: angulata—angulate.
