Four new genera of the family Proedischiidae Pinto & Ornellas, 1978 are described from the Upper Carboniferous of the Bajo de Véliz locality (Argentina): Velizphlebia cruzi gen. et sp. n., Paganzophlebia polyclada gen. et sp. n., Irajanarkemina gen. n. (type species Narkemina rodendorfi Pinto & Ornellas, 1978), Argentinonarkemina gen. n. (type species Paranarkemina amosi Pinto, 1992). The position of the genus Proedischia Pinto & Ornellas, 1978 from the Upper Carboniferous, Paraná Basin, is discussed, and Narkeminidae Pinto & Ornellas, 1991 is synonymised with Proedischiidae. Taiophlebiidae fam. n. is described from the Upper Carboniferous of Brazil. New combinations are proposed: Carpenteroptera rochacamposi (Pinto & Ornellas, 1978), comb. n., is transferred from the genus Narkemina Martynov, 1930 to the genus Carpenteroptera Pinto, 1990 (family Carpenteropteridae); Taiophlebia ferreirai (Pinto, 1994), comb. n., from the genus Archaemegaptilus Pinto, 1994 to the genus Taiophlebia gen. n. (family Taiophlebiidae); and Carpenteroptera rochacamposi (Pinto & Ornellas, 1978), comb. n., from the genus Narkemina to the genus Carpenteroptera Pinto, 1990 (family Carpenteropteridae).
