Abstract: Within the genus Hylaeus subgenus Deranchylaeus, from sub-Saharan Africa, a distinctive new subgroup of species is established. The females of this subgroup share a striking character: the orange-coloured lower face, previously known only in H. xanthostoma. The inter-specific differences are cryptic in both sexes. Seven species are newly described: Hylaeus (Deranchylaeus) aurantiacus sp. nov. ♀♂, H. (D.) burundis sp. nov. ♂, H. (D.) lyriformis sp. nov. ♂, H. (D.) sambiensis sp. nov. ♂, H. (D.) portokalius sp. nov. ♂♀, H. (D.) diastictus sp. nov. ♂ and H. (D.) jemeniticus sp. nov. ♀. This subgroup also includes H. (D.) promontorii (Meade-Waldo, 1923) and H. (D.) venustus Dathe, 2014, whose females are described for the first time. From Cameroon, the male of a second species of the subgenus Pumilaeus is described as new: H. (Pumilaeus) soukontouai sp. nov. New records of species of the genus Hylaeus F. in sub-Saharan Africa are added and a revised identification key to the subgenus Deranchylaeus is presented, to include the new species.

Abstract: New taxonomic, biological and faunistic data are presented for some species of sawflies occurring in southern Europe and North Africa. Pamphilius mediterraneus sp. nov. is described from Italy (Sicily). It belongs to the alternans sub-group of the alternans species group. Pristiphora omalos sp. nov. is described from Greece (Crete). It belongs to the depressa species group. New junior synonyms are Calameuta tazzekae Lacourt, 1991 of Calameuta gaullei (Konow, 1896), and Emphytus leucostomus Costa, 1890 of Allantus cingulatus (Scopoli, 1763). Periclista rufiventris Zombori, 1979 is moved from the subgenus Periclista to the subgenus Neocharactus. Ametastegia (Protemphytus) persica Khayrandish, Talebi & Blank, 2015 is recorded for the first time in Europe, from Italy (Sicily), and a key to West Palaearctic Protemphytus species provided. Allantus enslini (Forsius, 1918) is more widespread in southern Europe than previously recorded. An identification key distinguishes it from its closer West Palaearctic relatives. New hostplant records are for Halidamia affinis (Fallén, 1807) (Rubia peregrina), Janus compressus (Fabricius, 1793) (Sorbus torminalis), and Macrophya albicincta (Schrank, 1776) (Centranthus ruber). New distribution records are given for a few other species.
