INTRODUCTION

Guatemala has a complex topography and vegetation, which is reflected in its great biodiversity (Cano, 2006Cano, E.B. 2006. Biodiversidad de Guatemala. Centroamérica, Universidad del Valle de Guatemala. 674p.). In this country, the diversity of Cerambycidae was first summarized by Hovore (2006Hovore, F.T. 2006. The Cerambycidae (Coleoptera) of Guatemala. In: Cano, E.B. (Ed.). Biodiversidad de Guatemala. Centroamérica, Universidad del Valle de Guatemala. p. 363-378.), who reported 769 species. Currently, Tavakilian & Chevillotte (2021Tavakilian, G.L. & Chevillotte, H. 2021. Titan: base de données internationales sur les Cerambycidae ou Longicornes. Available: Available: http://titan.gbif.fr . Access: 27/04/2022.
http://titan.gbif.fr...
), listed six subfamilies, 72 tribes, 350 genera, and 894 species and subspecies of cerambycids from Guatemala.

Currently, Ectenessa Bates, 1885 (Ectenessini) is a genus with 21 species distributed mainly in South America. Only E. nitida Bates, 1885 occurs in Mexico and Central America (including Guatemala) (Bezark 2022aBezark, L.G. 2022a.

).

Oxycoleus Lacordaire, 1868 (Oxycoleini) includes 13 species known from Mexico to South America. Only two species are recorded in Guatemala, Oxycoleus mirabilis Nascimento & Santos-Silva, 2021 and O. piceus Giesbert, 1993 (Bezark 2022aBezark, L.G. 2022a.

).

Odontocera Audinet-Serville 1834 (Rhinotragini) is a polymorphic genus with 71 species distributed mainly in South America. Only, Odontocera aurocincta Bates, 1873 is the species with the southernmost record of the genus (United States, México, Guatemala, Honduras). In Guatemala, O. aurocincta Bates, 1873, O. clara Bates, 1873, O. fuscicornis Bates, 1885, and O. mthomasi Wappes & Santos-Silva, 2017 have been recorded (Bezark 2022aBezark, L.G. 2022a.

During the research stay of the first author in the University of the Valley of Guatemala (UVG) several unidentified coleopteran specimens were studied including those that represent undescribed species, which are described in the present work.

MATERIAL AND METHODS

Morphological structures were studied using a Zeiss Stemi 305 stereomicroscope (Carl Zeiss, Jena, Germany). Measurements and pictures were taken with a Zeiss® AxioZoom V16 stereomicroscope, with a Zeiss® AxioCam MRc5, 5 megapixels camera, controlled by ZEN (Zeiss Efficient Navigation) application.

Etymology: This species is dedicated to the recently deceased Enio Cano (Universidad del Valle de Guatemala), for his friendship, enthusiasm, and contribution to the knowledge of the diversity and conservation of Passalidae and Scarabaeidae in Guatemala.

Remarks: By the presence of two white elytral maculae on each elytron, Ectenessa canoi sp. nov. (Fig. 1) is most similar to E. ocellata (Gounelle, 1909), E. quadriguttata (Burmeister, 1865), and E. spinipennis (Buquet, 1860) (see photographs on Bezark, 2022bBezark, L.G. 2022b. A photographic Catalog of the Cerambycidae of the World. New World Cerambycidae Catalog. Available: Available: http://bezbycids.com/byciddb/wdefault.asp?w=n . Access: 23/04/2022.
http://bezbycids.com/byciddb/wdefault.as...
). Ectenessa canoi sp. nov. differs from E. ocellata and E. quadriguttata by the two semi-elliptical brownish areas on posterior half of the pronotum (integument unicolorous in E. ocellata, and with two longitudinal black areas centrally in E. quadriguttata), white semicircular-shaped maculae on the elytra (semi-elliptic in E. ocellata and E. quadriguttata), and elytral apex obliquely emarginate and with spiniforms projections (without spiniform projections in E. ocellata and E. quadriguttata). Ectenessa canoi sp. nov. differs from E. spinipennis by the semicircular-shaped maculae on the elytra (semi-elliptic in E. spinipennis, the later one oblique and more elongate) (Martins, 1998Martins, U.R. 1998. Ectenessini. In: Cerambycidae Sul-Americanos. Taxonomia. Volume 2. São Paulo, Sociedade Brasileira de Entomologia. p. 81-181.).

Etymology: This species is named after Jack Schuster (Universidad del Valle de Guatemala), a prominent entomologist interested in the study of the diversity and conservation of Guatemala, and author of several publications on the family Passalidae.

Remarks:Oxycoleus schusterisp. nov. differs from congeners by the metafemora distinctly not abruptly clavate, instead pedunculate. Oxycoleus schusteri sp. nov. is similar to O. brasiliensis (Tippmann, 1953) O. laetus Julio, 1997, and O. ruficollis (Zajciw, 1964) (see photographs on Bezark, 2022bBezark, L.G. 2022b.

http://bezbycids.com/byciddb/wdefault.as...
), but differs as follows: elytra narrower toward apex (almost subparallel in O. brasiliensis, O. laetus and O. ruficollis), metafemoral peduncle proportionally slender and longer (metafemoral club abruptly widened in O. brasiliensis, O. laetus and O. ruficollis).

Oxycoleus schusterisp. nov. resembles Callimoxys species (Stenopterini), but in this species, males have five abdominal ventrites, whereas in Oxycoleus schusteri sp. nov. there are six.

Etymology: The specific name nigroaurantia is composed from the Latin “niger, nigro” (black) and “aurantia” (orange), referring to the combination of black and orange integument.

Remarks:Odontocera nigroaurantiasp. nov. (Fig. 3) is similar to O. annulicornis Magno, 2001, and O. molorchoides (White, 1855) (see photographs on Bezark, 2022bBezark, L.G. 2022b. A photographic Catalog of the Cerambycidae of the World. New World Cerambycidae Catalog. Available: Available: http://bezbycids.com/byciddb/wdefault.asp?w=n . Access: 23/04/2022.
http://bezbycids.com/byciddb/wdefault.as...
). It differs from both by the femora in the male holotype specimen, especially the metafemora, shorter and club distinctly stouter (longer and club slender in O. annulicornis and O. molorchoides).
