Four species of Peneckiella SOSHKINA, 1939 are recorded in the middle part of the Frasnian. In the Philippeville Massif, P. isylica (BULVANKER, 1958) and P. fascicularis (SOSHKINA, 1939) have been collected in the lower part of the Philippeville Formation. The latter species also occurs on the south side of the Dinant Synclinorium: at the base of the Bieumont Member in the Focant borehole and in the Lion Member of North Quarry at Frasnes-lez-Couvin. P. duponti n. sp. is abundant in the intercalations of red marble located at the base of this exposure whereas P. szulczewskii ROZKOWSKA, 1979 has been found at the base of the Boussu-en-Fagne Member. Several of these species are associated with Hexagonaria mirabilis MOENKE, 1954, Scruttonia balconi COEN-AUBERT, 1980 and S. focantiensis (TSIEN, 1978) senior synonym of S. boloniensis minor COEN-AUBERT, 1980.
