Acari DNA barcoding cytochrome c oxidase I (COI) sexual dimorphism water mite Sperchon

Abstract

Sperchon fuxiensis Zhang, 2017 was published as a new species based on females alone. Two males of Sperchon were found in the same locality during our recent collection. The males resemble S. fuxiensis female in the integument pattern, excretory pore and the palps shape, but the chitinous plates of both dorsum and venter differ greatly. The males were paired with the female of S. fuxiensis using DNA barcoding, revealing unusual sexual dimorphism in the species. Descriptions and illustrations of the male of S. fuxiensis are given in the present study. Species identification based on the full-length DNA barcoding (658bp) of COI in water mites is also discussed.
