The population structure of Guignardia citricarpa sensu lato (anamorph: Phyllosticta citricarpa), a fungus of which strains pathogenic to citrus are subject to phytosanitary legislation in the European Union and the United States, was investigated. Internal transcribed spacer sequences revealed two phylogenetically distinct groups in G. citricarpa. This distinction was supported by amplified fragment length polymorphism analysis that also supported the exclusion of two isolates that had apparently been misclassified as G. citricarpa. On cherry decoction agar, but not on other media, growth rates of group I isolates were lower than those of group II isolates. Conidial dimensions were similar, but group I isolates formed conidia with barely visible mucoid sheaths, whereas those of group II formed conidia with thick sheaths. Cultures of isolates belonging to group I produced rare infertile perithecia, whereas fertile perithecia were formed by most isolates of group II. Colonies of isolates belonging to group I were less dark than those of group II, with a wider translucent outer zone and a lobate rather than entire margin. On oatmeal agar, exclusively group I isolates formed a yellow pigment. Group I harbored strains from citrus fruits with classical black spot lesions (1 to 10 mm in diameter) usually containing pycnidia. Group II harbored endophytic strains from a wide range of host species, as well as strains from symptomless citrus fruits or fruits with minute spots (<2-mm diameter) without pycnidia. These observations support the historic distinction between slowly growing pathogenic isolates and morphologically similar fast-growing, nonpathogenic isolates of G. citricarpa. The latter proved to belong to G. mangiferae (P. capitalensis), a ubiquitous endophyte of woody plants with numerous probable synonyms including G. endophyllicola, G. psidii, P. anacardiacearum, and P. theacearum. G. mangiferae occurs in the European Union and the United States on many host species including citrus, and does not cause symptoms of citrus black spot, justifying its exclusion from quarantine measures.

Taxonomic Changes

This paper is based almost entirely on material in the Canadian National Collection. It proposes several taxonomic changes, which are detailed in the summary that concludes the paper. It outlines the Canadian and Alaskan distribution of the forms considered and is, perhaps, justified by the paucity of published records of distribution in the more northern regions. The records for Hippodamia are based on more than 2,000 specimens that were identified by de Ruette; these records supplement those of Chapin (1946, Smithsonian Misc. Coll. 106(11): 1-39), who revised the New World forms of the genus and mapped their distribution in the United States.

Annotated List

AbstractEighty-three butterfly species are credited to the fauna of the Yukon Territory, with an additional three deemed questionable. Species enumerated represent a compilation of both historic and current literature, and the records of collectors. The total includes previously unpublished records from the Canadian National Collection, but does not include unpublished records from any major museums in the United States. Approximately 30 collectors contributed field data.
