Abstract / Notes

The genus Pseudomonocelis Meixner, 1943 is treated in a monographic way, with the provisory re-introduction of
P. agilis (Schulze, 1851). A comprehensive description of all representatives of the genus is given,
including two new species from the neighbourhood of Mogadiscio, Somalia, P. pardii and P. cavernicola. Both
species have a muscular vagina and a large bursa lying behind the female duct. P. pardii is further
characterised by the fact that the vagina ends in a muscular canal which opens anteriorly into the bursa and
posteriorly receives the oviducts where the common female duct begins. It also has an extremely muscular
penial organ. The most striking feature of P. cavernicola is an ovoid muscular organ between the female and
the male genital pore. Possible phylogenetic relationships of and within the genus are discussed.
