Two species previously placed in Euconnus s. str. belong in the endemic Madagascan subgenus Glabriconnus (Coleoptera: Staphylinidae: Scydmaeninae)

The Madagascan species Franz, 1986 and Franz, 1986 are redescribed and transferred from s. str. to the subgenus Jałoszyński, 2016. They share with ( ) Franz, 1986 the evenly convex frons and vertex, and lack of a pair of diffuse longitudinal carinae (present in all remaining species of ), and with ( ) Jałoszyński, 2016 the presence of two distinct hypomeral grooves (one variously distinct groove in remaining species). The unique character for and is the transverse antebasal groove connecting a pair of lateral pits, which was not previously known in any other . Consequently, the diagnosis of is here emended to include a considerable variability in pronotal structures. The distribution of in Madagascar is summarized.
