Abstract: Stenocephus janseni sp. nov. (Hymenoptera: Cephidae) is described from
Brandenburg, eastern Germany, known only from the female holotype. It possesses
an unusual combination of “generic” morphological characters, which makes
its placement in Stenocephus Shinohara, 1999 provisional. Compared to other
Stenocephus species, differences in the morphology of the lancet are
particularly striking. Genetic data for S. janseni sp. nov. place it
unequivocally in the Hartigiini, but rather distantly from other genera of this
tribe which have so far been sequenced. The three previously described
Stenocephus species are recorded from the East Palaearctic. No genetic data are
currently available for these. Pachycephus nigratus Dovnar-Zapolskij, 1931,
comb. restit., is no longer treated as belonging to Phylloecus Newman, 1838, but
as a member of the genus in which it was originally described.
