Decma fissa is the most widely
distributed species of the genus Decma
occuring in southern China. This study presents the first
phylogeographic work of D. fissa
based on COI, Cytb and ITS sequence. We examined genetic
diversity with ITS and
mitochondrial sequence respectively, and phylogenetic work was based on
the mitochondrial data. A high-level genetic diversity was revealed
based on mitochondrial data but a low-level diversity was shown with ITS sequence. For the mitochondrial
data, divergence time analysis displayed five lineages. Based on the
Mantel test, geographic and genetic distances among D. fissa populations revealed a
significant positive correlation. Bayesian skyline plot (BSP) analyses
implied that none of three major lineages of D. fissa was seemingly affected by
the last glacial maximum (LGM, 0.015–0.025 Mya). Ecological niche
modeling was used to predict the distribution of D. fissa in four periods (LGM,
Mid-Holocene, current and 2070) in China. Analysis of the ancestral
area reconstruction indicated that D.
fissa occurred in the South China area.
