title: Issatchenkia hanoiensis, a new yeast species isolated from frass of the litchi fruit borer Conopomorpha cramerella Snellen.
abstract: The new ascogenous yeast species Issatchenkia hanoiensis was discovered in the frass of the litchi fruit borer Conopomorpha cramerella Snellen. The yeast forms unconjugated persistent asci containing one to two roughened ascospores. The yeast has a CoQ-7 system, which is typical for the genus Issatchenkia. The closest species to I. hanoiensis as indicated by analysis of the partial ribosomal DNA large-subunit (D1/D2) sequence is the asexual species Candida pseudolambica. The two share 94.2% similarity in the sequenced region. Other species of Issatchenkia were also among the closest relatives of I. hanoiensis, the level of similarity ranging from 89.8% to 94.1%. The type culture is strain HB1.3.13=CBS 9198=NRRL Y-27509.
