Tres especies nuevas son descritas aquí, una del bosque deciduo de las tierras bajas costeras del occidente de México (Jalisco), otra del matorral deciduo de las tierras bajas costeras de Ecuador occidental (Manabi), y la última de la parte alta del Amazonas en Ecuador (Napo). PALABRAS CLAVES: Cerambycidae, Ceralocyna, Mexico, Ecuador. Monné and Napp (2000) recently revised the Ceralocyna aliciae sp. nov. genus Ceralocyna Viana to contain 14 described (Figure 1) species, all but two of which, C. cribricollis Male.

Three new reddish-brown, elytra dark red, basal area pi- species of Ceralocyna are described herein, one ceous, a broad, well-defined, central, piceous from coastal lowland deciduous forests of vitta extending from base to apex, becoming less western Mexico (Jalisco), one from coastal low- well-defined over apical one-third.

Abdomen broad, sparsely, moderately rugoso-punctate, apices acuminate; antennae with coarsely punctate, more coarsely so at lateral 11 antennomeres, slender, surpassing elytral apex margins, punctures becoming finer apically, erect by 2 – 3 antennomeres, scape shining, lightly, hairs arising from punctures, terminal sternite sparsely punctate, punctures bearing short, erect broadly, feebly emarginate at apex.
