          Abstract

          Se revisaron 897 ejemplares del género Deltochilum de nueve colecciones entomológicas. Se estudió la taxonomía de las especies de los subgéneros Calhyboma, Hybomidium y Telhyboma. Se reconocieron y redescribieron diez especies y una subespecie pertenecientes a los subgéneros Calhyboma (D. (C.) hypponum, D. (C.) luederwaldti, D. (C.) mexicanum, D. (C.) tessellatum, D. (C.) cristinae, D. (C.) carinatum), Hybomidium (D. (H.) amazonicum, D. (H.) sp., D. (H.) lobipes, D. (H.) gibbosum panamensis) y Telhyboma (D. (T.) orbiculare). Se describen dos especies nuevas del género y la hembra de D. (Calhyboma) luederwaldti. D. (Calhyboma) luederwaldti y D. (Calhyboma) cristinae son nuevos registros para Colombia. Se amplía la distribución regional de siete de las especies de estos tres subgéneros. Se presenta la descripción del órgano genital masculino de todas las especies y se incluye un análisis comparativo de su variación morfológica. La escultura elitral de todas las especies se presenta e ilustra en detalle. Solo el 10% del material examinado estaba identificado a especie correctamente. Este estudio mejora el conocimiento taxonómico del género Deltochilum en Colombia.

          Translated abstract

          A total of 897 specimens of the genus Deltochilum from nine entomological collections was reviewed. The taxonomy of the species of the subgenera Calhyboma, Hybomidium, and Telhyboma was studied. Ten species and one subspecies of the subgenera were identified and redescribed as follows: Calhyboma (D. (C.) hypponum, D. (C.) luederwaldti, D. (C.) mexicanum, D. (C.) tessellatum, D. (C.) cristinae, D. (C.) carinatum), Hybomidium (D. (H.) amazonicum, D. (H.) sp., D. (H.) lobipes, D. (H.) gibbosum panamensis) and Telhyboma (D. (T.) orbiculare). Two new species of the genus and the female of D. (Calhyboma) luederwaldti are described. D. (Calhyboma) luederwaldti and D. (Calhyboma) cristinae are new records for Colombia. The regional distribution of seven species of these three subgenera is extended. The description of the male genital organ of all the species is presented and a comparative analysis of their morphological variation is included. The elytral sculpturation of all species is presented and illustrated in detail. Only 10% of the specimens studied had been correctly identified to species. This study improved the taxonomic understanding of the genus Deltochilum in Colombia.
