Type material. Holotype female from ECUADOR, Imbabura: Cabañas Intag Colibri , 1900 m, Intag, 18 Jun 2023, J. Vlasak leg. ( MZSP).

Etymology. The specific epithet “apicalis ” (Latin, “apex,” meaning tip or end) refers to the brown elytral apex.

Remarks. Antodice apicalis sp. nov. is similar to A. nascimentoi Bezark, Botero & Santos-Silva, 2022 (see photographs on Bezark (2025) and in Bezark et al. (2022)), the only other species of the genus with the antennomere III distinctly not cylindrical, but differs as follows: frons abundantly, finely punctate with coarse punctures interspersed; maximum diameter of upper eye lobes 3.5 times shorter than maximum diameter of scape; lower eye lobes 1.4 times as long as genal length; in frontal view, distance between lower eye lobes 3.5 times genal length; elytra with large, inverted letter psi-shaped black macula on anterior 2/3; posterior elytra brown on posterior eight. In A. nascimentoi , the frons is very sparsely finely punctate laterally, these punctures are absent centrally, with coarse punctures interspersed, the maximum diameter of the upper eye lobes is 2.5 times shorter than the maximum diameter of the scape (although usually the width is narrower than in males in other species, the difference is always very small), the lower eye lobes are twice longer than the genal length, in frontal view, the distance between the lower eye lobes is 3.0 times the genal length, the elytra have longitudinal reddish-brown band close to suture on the anterior basal third, and the posterior half of elytra is entirely orangish.

The non-cylindrical basal flagellomeres may suggest that this species, like A. nascimentoi , does not belong to Antodice . However, the existence of species with intermediate basal flagellomeres, as for example in A. neivai Lane, 1940 , does not allow them to be separated from this genus.
