Hypogean Quedius of Taiwan and their biogeographic significance (Coleoptera: Staphylinidae: Staphylininae)

Fang Shuo Hu, Amalia Bogri, Alexey Solodovnikov, Aslak Kappel Hansen

Abstract


As a result of the integrative (morphology and DNA barcodes) revision of the Taiwanese species of the rove beetle genus Quedius belonging to the abnormalis group, in the subgenus Microsaurus, three valid hypogean species are reported for the fauna of this island: Quedius masuzoi Watanabe, 1989, Q. nishikawai Watanabe, 1991 and Q. adilus sp. nov. A new synonymy, Quedius masuzoi = Quedius chiangi Smetana, 1995 syn. nov., is established along with providing additional records, a larval description and bionomic information for this species. Finally, the biogeographic origin of the abnormalis group in Taiwan is discussed.
