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