Hemiptera Granulidae Triassic Yanchang Formation taxonomy Sinogranulus

Abstract

Granulidae is a small extinct hemipteran family with only two genera from the Middle Triassic of northern China. Here we describe and illustrate a new species of Granulidae, Sinogranulus jinsuoguanensis Fu & Huang sp. nov., from the Middle Triassic Yanchang Formation of Tongchuan City, Shaanxi Province, northern China, representing the second species of Sinogranulus Zhang, Chen & Zhang, 2022, adding new information on morphological diversity of this genus. In addition, Sinogranulus is emended and provided with a supplemental description for the type species Sinogranulus qishuiheensis based on four specimens from the same locality of Yanchang Formation with S. jinsuoguanensis sp. nov., and the intra-specific variation of venation in two species of Sinogranulus is discussed.
