Nine strains were studied of a new haploid species of the genus Lodder&Kreger-van Rij that had been isolated from exudates of mesquite () trees in southern Arizona and from that breeds in these exudates. Their physiological characteristics, life cycle, and nuclear DNA base composition (approx. 37·5 mol% G+C) led to their original classification as (Zopf) Kreger-van Rij. However, the two taxa are, at most, distantly related based on DNA reassociation values that indicated low base sequence complementarity. The two taxa also have distinctly different electrophoretic karyotypes. has two varieties, var. and var. can be differentiated phenotypically from both varieties by lack of growth on cellobiose after 2 weeks incubation and from the variety by a higher maximum temperature for growth. The type strain of sp. nov. is strain UCD-FST 84–100(= DBVPG 7010= CBS 8450= ATCC 201611).
