The genus Striglina is the most species-rich genus in the subfamily Striglininae, which includes about 80 species and subspecies and it has always been a popular research taxon within Thyrididae.
Two new species of the genus Striglina Guenée, 1877, S. whalleyi sp. nov. and S. pararubricans sp. nov. from China are described and illustrated. Striglina whalleyi sp. nov. is similar to S. irresecta obscura Whalley, 1976, but its wing ground colour is lighter and the sacculus process is shorter. Striglina pararubricans sp. nov. is similar to S. rubricans, but the fore-wing is narrower, the uncus processes and sacculus process are longer. Holotypes are deposited in the Department of Entomology, College of Plant Protection, South China Agricultural University, Guangzhou.

The genus Striglina was established by Guenée in 1877 with S. lineola Guenée, 1877 as its type species. To avoid replacing a better-known generic name by another unused name, the International Commission on Zoological Nomenclature placed the name Striglina on the Offical List instead of the order generic name Daristane Walker, 1850 (
The specimens were collected using a light trap. Adults were photographed by a NIKON CoolPix S7000 digital camera. Abdomens were removed and macerated in hot 10% sodium hydroxide (NaOH) solution for examination of genitalia, photographs of which were taken under a Zeiss SteReo Discovery V.12. Adults and genitalia photos were all processed by Adobe Photoshop CC2018 software. Terminology of adult and genitalia follows

This new species resembles S. irresecta obscura Whalley, 1976, but the ground colour of wings is yellow (reddish-brown in the latter, Fig.
The species is dedicated to Mr. Paul Ernest Sutton Whalley, in honour of his marvellous work on Thyrididae.
China: Yunnan (Chuxiong), Guangdong (Shaoguan).
Our study shows that S. irresecta obscura seems more closely related to the new species than to S. irresecta irresecta morphologically and zoogeographically. Judging from the holotype pictures (Fig.

This wing pattern of the new species resembles S. rubricans Owada et Huang, 2016, but the fore-wing is narrower and the outer margin is curved (triangular fore-wing in rubricans Fig.
The specific name pararubricans is derived from the other specific name rubricans due to the resemblance of the present new species in morphological characters to the species S. rubricans.
China: Guangdong (Shaoguan).
We thank Mr. Hai-Ming Xu and Ms. Hai-Ling Zhuang for helping to collect specimens, Mamoru Owada for providing references and Ms. Lan-Lan Huang for other various Thyrididae taxonomic guides.
