Abstract
The extinct Eocene Baltic amber genus Propelma Trjapitzin 1963 is removed from synonymy under Eupelmus Dalman 1820 (Hymenoptera, Eupelmidae, Eupelminae) and treated as a valid genus within Neanastatinae Kalina 1984 based on examination of the holotype female of Propelma rohdendorfi Trjapitzin. Propelma rohdendorfi is redescribed, illustrated by photomacrographs, and compared to other described extant and extinct genera of Neanastatinae. Taxonomic, morphological and geological diversity of Neanastatinae relative to Eupelminae and Calosotinae is also discussed relative to potential age of the subfamily.
Highlights
Trjapitzin (1963) established Propelma based on Propelma rohdendorfi (Hymenoptera: Eupelmidae), which he described from a single female in Eocene Baltic amber. Gibson (1995) later synonymized Propelma under Eupelmus Dalman 1820 in a revision of the world genera of Eupelminae Walker 1833
Images were taken with a Leica DFC 425C, 5 megapixel digital camera attached to a Leica Z16 APO macroscope
Images taken of the right side of the holotype for the plates of illustrations were flipped so that they face in the normal direction for specimen observation

Trjapitzin (1963) established Propelma based on Propelma rohdendorfi (Hymenoptera: Eupelmidae), which he described from a single female in Eocene Baltic amber. Gibson (1995) later synonymized Propelma under Eupelmus Dalman 1820 in a revision of the world genera of Eupelminae Walker 1833. The synonymy was based primarily on the lateral habitus drawing of P. rohdendorfi given by Trjapitzin P. Gibson / ZooKeys 283: 59–69 (2013)
