Patterns of endemism of the Chinese Larentiinae (Lepidoptera: Geometridae)

Chinese Larentiinae is exceptionally rich in species since it spans the Palearctic realm and the Oriental realm, comprising 715 species belonging to 130 genera. Among them, nearly half species are endemic. This taxon is considered an ideal object for the study of endemic patterns. In this study, parsimony analysis of endemicity was used to delineate areas of endemisms (AOEs), and track compatibility analysis (TCA) was used to perform the TCA. Eight AOEs were supported. Except for five AOEs around the Qinghai-Tibet plateau (QTP), two AOEs from northern China and Taiwan islands were found. Twenty-two generalized tracks were obtained from the combination of the track analysis and the AOEs. The uplift of the QTP was assumed to greatly influence these endemic patterns, presented an appearance of highly centralized endemism and diversity in the eastern and southern edges of the QTP. And the AOE of Mt. Hengduan was considered as a major center of development through recent geological history, where strong evolutionary radiation might have taken place, resulting in the migration routes described by the generalized tracks from this center to various regions in various directions.
