PATTERNS OF MITOCHONDRIAL AND WING MORPHOLOGICAL DIFFERENTIATION IN TAIWANESE POPULATIONS OF PSOLODESMUS MANDARINUS McLACHLAN (ZYGOPTERA: CALOPTERYGIDAE)

摘要

To investigate the patterns of molecular and morphological differentiation, the mitochondrial cytochrome oxidase I and 16S ribosomal DNA genes and wing morphology data were analyzed. Both phylogenetic and population genetic analyses revealed two lineages, an Eastern and a Western lineage existing on each side of the longitudinal Central Mountain Range. For wing traits, the latitudinal dines mainly altered across the populations in northern Taiwan and the transition zone was broad. For female wing size, however, the latitudinal cline shifted at 24.19 degrees N latitude, which is close to the current criteria (24.33 degrees N latitude line) for dividing 2 geographical sspp., P. m. mandarinus and P. m. dorothea.
