Fig. 2From: Molecular evidence for new sympatric cryptic species of Aedes albopictus (Diptera: Culicidae) in China: A new threat from Aedes albopictus subgroup?Cox1 haplotype networks showing the genealogical relationships. a-c Aedes albopictus. d Cryptic Aedes species. Each haplotype is represented by a pie chart with size proportional to its frequency in each population. A black dotted line indicates that a mutation step could not be determined between haplotypes at probability of parsimony above the 0.95 limitBack to article page
