Abstract

As part of a long-term study aiming to isolate and identify yeast species that inhabit the surface of leaves and fruits of native fine-aroma cacao in the department of Amazonas, Peru, we obtained multiple isolates of Hannaella species. Yeasts of the genus Hannaella are common inhabitants of the phyllosphere of natural and crop plants. On the basis of morphological, and physiological characteristics, and sequence analysis of the D1/D2 domains of the large subunit rRNA gene (LSU) and the internal transcribed spacer region (ITS), we identified five species of Hannaella from the phyllosphere of Peruvian cacao. Four have been previously described: H. phyllophila (isolates KLG-073, KLG-091), H. pagnoccae (KLG-076), H. sinensis (KLG-121), and H. taiwanensis (KLG-021). A fifth, represented by eight isolates (KLG-034, KLG-063, KLG-074, KLG-078, KLG-79, KLG-082, KLG-084, KLG-085), is not conspecific with any previously described Hannaella species, and forms the sister clade to H. surugaensis in the phylogenetic analysis. It has 2.6–3.9% (18–27 substitutions, 2–4 deletions, and 1–3 insertions in 610–938 bp-long alignments), and 9.8–10.0% nucleotide differences (37 substitutions and 14 insertions in 511–520 bp-long alignments) in the LSU and ITS regions, respectively, to H. surugaensis type strain, CBS 9426. Herein, the new species Hannaella theobromatis sp. nov. is described and characterised. The species epithet refers to its epiphytic ecology on its host Theobroma cacao.
