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 last glacial maximum (LGM, 0.015 – 0.025 Mya). The
Ecological niche modeling was used to predict 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 South China area.
