Neobisium henderickxi n. sp. is described from a Baltic amber (upper Eocene) fossil. It is very similar to the Recent species N. kobachidzei Beier, 1962 and N. speleophilum Krumpál, 1986 from the Caucasus. The fossil species Obisium rathkii Koch & Berendt, 1854 and Pycnochelifer kleemanni (Koch & Berendt, 1854) are synonymized and the latter name is given precedence. Neobisium rathkii (non Koch & Berendt) sensu Menge 1855 and Beier 1937 represents a different species, whose identity remains uncertain. It is compared to Microcreagris koellnerorum Schawaller, 1978 (nom. emend. pro Microcreagris koellneri) and to a poorly preserved neobisiid fossil in the Baltic amber collection of the Zoological Museum, Copenhagen University.
