Unveiling Weevil Diversity Drivers and Cryptic Species on the Qinghai-Xizang Plateau.

ABSTRACT: Understanding patterns and mechanisms of species diversity is one fundamental issue in biogeography and ecology. As a critical region for biodiversity, the Qinghai-Xizang Plateau (QXP) still has unclear distribution patterns and drivers for cryptic, understudied taxa such as Curculionoidea. Here, we collected the distribution data of Curculionoidea on the QXP to analyze their diversity patterns and influencing factors, and compiled a DNA barcode dataset to uncover cryptic diversity. This comprehensive dataset encompasses 671 Curculionoidea species across 223 genera, demonstrating a level of diversity that surpasses that of certain vertebrate groups. We also observed an unbalanced biogeographic pattern of diversity, with a concentration of species in the eastern and southern regions and a s
