A preliminary review of the taxonomic characters used for the systematics of the genus , Claparède (or blood vessels are not well documented for a significant proportion of the species and these characters need to be tested for environmentally induced variation. Taxonomic value of structural traits is strengthened against characters related to size. Thus, a key to the species of the genus is provided, emphasising such structural characters.
