The aetheraea species-group

Five species in Ethiopia. This grouping seems genetically very 'robust' in different alignments, algorithms, and also when excluding the third codon position from analysis. In male genitalia this is a rather homogenous group, socii absent (or reduced to small, hardly visible, setose patches), sacculus strongly sclerotized, with long and narrow, dorsal projection forming a characteristic forceps-shaped structure, sternum A8 usually with sclerotized bilobous projection at centre. P. stictimargo (Warren, 1902) from Kenya may also belong to this group, judging from the shape of dorsal projection of sacculus in male genitalia, but here the ventral part of sacculus is not sclerotized to tip. For possible relationships with P. robusta sp. n. and P. amharensis sp. n. see above under the nereis species-group.
