Abstract

The genus Liassophyllum Zeuner, 1935 is redescribed, and its uncertain systematic position is discussed and partially clarified: it may belong to an unknown subfamily of Tuphellidae or to the subfamilies Isfaropterinae or Haglinae within Haglidae. Some probable additional characters of the type species Liassophyllum abbreviatum Zeuner, 1935 from the Lower Jurassic of England are indicated. A new species is described: Liassophyllum patriciae sp. nov. from the Lower Jurassic of England. Liassophyllum caii Gu & Ren, 2012, from the Middle Jurassic of China, is transferred to a new genus: Gurenia gen. nov., which may be referred to the subfamilies Isfaropterinae or Haglinae within Haglidae.
