Diagnosis. Chimoptesis dentitia is closely related to C. potosiana and C. chrysopyla , but C. dentitia is distinguished by its pale brownish cream colouration with incomplete forewing markings, slenderer trinagular termination of the uncus, triangular socii, and presence of three distinct terminal thorns of the aedeagus.

Description. Wing span 18 mm. Male: Head and thorax cream tinged brownish. Forewing similar to that of C. angulata ; costal fold to beyond 1/3 forewing length. Ground colour cream suffused brownish; strigulation browner; costal strigulae fine; divisions yellowish brown, ocellus similarly suffused; terminal area concolorous with suffusions. Markings yellow brown consisting of remnants of basal blotch, a slender costal part of median fascia, an elongate-triangular tornal blotch, and subapical markings. Cilia brownish cream. Hindwing cream, tinged brown on peripheries; cilia cream. Genitalia ( Fig. 5 ) with uncus moderately broad, triangular terminally; socius tapering terminally; sacculus angulate; neck of valva slender; cucullus broad near middle; aedeagus rather long, armoured with three terminal thorns.

Female: Head and thorax as in male. Genitalia ( Fig. 20 ) with posterior part of sterigma incised medially; antrum sclerite broad; cingulum rather well sclerotized; signa large.

Holotype male. " Mexico: Chiapas, San Cristobal de las Casas, 2300 m, 23–27. VI. 1981, V.O. Becker Col; Col. Becker 43773"; GS 848 WZ. Two male and two female paratypes with identical label data.

Etymology. The specific epithet refers to apical thorns of the aedeagus; Latin: dentitio—dentation.
