A revision of the fossil genus Ulmeriella (Isoptera, Hodotermitidae, Hodotermitinae). American Museum novitates ; no. 2332

Abstract

"The fossil genus Ulmeriella is redescribed. Five species from temperate Tertiary deposits of Europe, Asia, and North America are included. Ulmeriella is considered to be the most primitive member of the Hodotermitinae and partially bridges the gap between the Termopsinae and Hodotermitinae within the family Hodotermitidae. Phylogenetic, biogeographical, and paleoecological interpretations are included. A brief discussion of the degree of variation and the limits of species among fossil termites is presented. Ulmeriella bauckhorni Meunier from upper Middle Oligocene beds, Rott, Germany, is redescribed and figured, and U. rottensis (Statz) is placed in synonymy. Ulmeriella cockerelli Martynov, known from a forewing from Upper Oligocene beds of Ashutas, Siberia, is discussed, and Diatermes sibiricus Martynov is placed in synonymy. Ulmeriella martynovi Zeuner, known from an imago from Lower Miocene beds of Biebrich, Germany, is discussed. Ulmeriella latahensis Snyder from Upper Miocene beds of Washington is redescribed. Ulmeriella willershausensis Weidner from Pliocene beds of Willershausen, Germany, is discussed"--P. 20.
