New species, new synonymy, taxonomic notes and new records of bark and ambrosia beetles from the southwestern United States and northern Mexico (Coleoptera: Curculionidae: Platypodinae and Scolytinae) Author Atkinson, Thomas H. text Zootaxa 2024 2024-03-13 5424 2 151 175 http://dx.doi.org/10.11646/zootaxa.5424.2.1 journal article 10.11646/zootaxa.5424.2.1 1175-5326 10821033 A7F58813-74B7-4871-B562-52999092C283 Chramesus mimosae Blackman, 1938 Chramesus mimosae Blackman, 1938: 544 Chramesus varius Wood, 1969: 4 : new synonymy Chramesus varius was distinguished from C. mimosa e primarily on the basis of color variations in the scales and distribution from central Mexico and southern Texas, respectively. In a long series collected by the author in southern Nuevo León the variation in color pattern completely encompassed both types . Recent collections have completely closed any geographic gaps ( Fig. 2 D ). It is clear that only a single species is represented. All reported hosts are legumes, including Mimosa sp., Acacia sp. , and Leucaena pulverulenta . Based on collection localities, this species is found in or adjacent to thorn forests, probably in riparian habitats, from central Mexico to southern Texas.
