Diagnosis: This species can be distinguished from A. tubericollis Bates, 1885, by the pronotal shape and the pubescent pattern of elytra. In A. santossilvai the anterior pronotal depression slopes gradually from the tubercles toward the apex and is deeper at the middle and superficial toward the sides, making the sides of the pronotum more widely rounded. In A. tubericollis, the anterior pronotal depression slopes abruptly from the tubercles to its lower part, covering the entire apical quarter; from the middle to the sides it is equally deep, making the sides of the pronotum more rounded. In A. santossilvai the whitish semicircular median fascia on the elytra is elongate, not reaching the sutural margin, it becomes narrow posteriorly; appressed pubescence on the apical fourth with front margin oblique on each side. In A. tubericollis, the semicircular median fascia is short but reaches the elytral suture, forming an X, and the appressed pubescence on the apical fourth has its front margin curved.

Etymology: We dedicate this species to Antonio Santos Silva (MZSP) in recognition of his helpful demeanor and his many contributions to our knowledge of the Neotropical Cerambycidae.

Diagnosis: This species resembles C. mimulus, from which it may be separated by the sides of the pronotum being broadly rounded and the elytra superficially bi-costate and punctate. In C. mimulus, the sides of the pronotum in apical half are almost straight and abruptly rounded in the basal half, the elytra lack costae but are deeply punctate. This species is distinguished from C. cinnabarinus Chemsak and Linsley, 1979, another species with reddish-orange integument, by the pronotum with sides less rounded and the apical third of disc without a depression. In addition, both the pronotum and elytra are sparsely pubescent; in C. cinnabarinus, the sides of the pronotum are strongly rounded and the disc has a single depression in apical third extending from the sides to the midline and the pubescence of the pronotum and elytra is dense.

Etymology: This species name refers to the brownish-orange color of its body.

Description: Holotype female. Length 14.5 mm; width: 5.3 mm. Moderate size, form robust, almost parallel sided.

Legs clothed with beige dense pubescence, with long, erect setae interspersed on femora and tibiae. Abdomen: with fine beige pubescence, with margins of segments 1-4 fringed with whitish dense pubescence and long setae scattered along the last fourth segments; last abdominal segment with a medium triangular depression, deep at the apex and becoming more superficial to the middle part, from where it continues to the base as a black glabrous line, with apex widely rounded and slightly emarginated in the middle.

Type material: Holotype female (CNIN), MEXICO: Chiapas: Municipio de Ocosingo, Chajul, Reserva Montes Azules, 28.IV–5.V.1986, F. Arias, R. Barba, and L. Cervantes.

Diagnosis: This species is distinguished from Z. perpulchra Lane and Z. plumbea Machado and Monné by the non-tuberculated mesocoxal process, unlike those two species that have a well-defined tubercle. From Z. diversicornis Nascimento, Santos-Silva and Barclay, it differs by presenting the tubercles of the pronotum considerably higher and by the central depression of the fifth abdominal segment extending to the middle part. In Z. diversicornis the tubercles of the disc are lower and the central depression of the fifth abdominal segment extends from the apex to the base. It differs from Z. biocellata (Tippmann) and Z. argenteofasciata (Tippmann), by the strongly sinuate apex of elytra and the slightly emarginate apex of the last abdominal segment, both of which are almost straight in the former species.

Distribution: This is the first North American record of Zikanita, which had previously been recorded only in South America (Bolivia, Brazil, Ecuador, and Peru: Machado and Monné, 2011, Nascimento et al., 2019).

Etymology: We dedicate this species to Miguel A. Monné in recognition of his lifetime of producing notable contributions to our knowledge of the Neotropical Cerambycidae.
