Taxonomy, phylogeny, and biogeography of the Oriental subfamily Perittopinae China & Usinger, 1949 (Hemiptera: Heteroptera: Veliidae).

ABSTRACT: The collision of the Indian and Eurasian plates during the Eocene represents a major tectonic shift that significantly altered biotic dynamics and promoted species diversification across the Oriental region. To explain the diversification of taxa from the Indian subcontinent into Southeast Asia, two principal hypotheses have been proposed: the "Biotic-ferry" and "Step-stone" models. The subfamily Perittopinae, a lineage of semi-aquatic bugs comprising a single genus and 20 extant species, provides an ideal system for testing these hypotheses due to its disjunct distribution spanning the Indian subcontinent and Southeast Asia. This study conducted a comprehensive taxonomic analysis of the entire subfamily, incorporating newly defined morphological characters and multilocus phylogenetic anal
