Distribution and phylogenetic position of Spiralizoros hainanensis (Zoraptera: Spiralizoridae)

Abstract

Spiralizoros hainanensis (Yin & Li, 2015) (Zoraptera: Spiralizoridae) was originally described in Hainan, China. Here, we report for the first time the occurrence of this species in Vietnam on the basis of specimens from Lâm Đồng Province. Via a combination of newly generated molecular data and a detailed morphological investigation of S. hainanensis, we confirmed that the DNA data of this species from Vietnam were previously published under the name Zorotypus sp. This species represents the only known Zoraptera species from Vietnam. In addition to contributing to the morphology of adult males and females, we present a molecular phylogenetic reconstruction of Zoraptera specifically focused on the genus Spiralizoros Kočárek, Horká & Kundrata, 2020 and the position of S. hainanensis.
