Fig. 35From: The male sexual apparatus in the order Scorpiones (Arachnida): a comparative study of functional morphology as a tool to define hypotheses of homologyAncestral state reconstruction of the absence/presence of a capsular basal invagination on phylogenies by Stockwell [4]Â (a), Prendini [45]Â (b), and Sharma et al. [106]Â (c). Taxa, traditionally recognized as hormurids, are indicated in brown, and taxa possessing a weak or absent invagination of the basal capsular edge in green. Consistency and retention index values are indicated for each cladogramBack to article page
