Material – Kreekrak (1 complete specimen, 3 brachial valves; 6 fragments).

Remarks – N. nysti was originally described by DAVIDSON (1874b) from the “Scaldisien” (= Pliocene, Late Zanclean to Piacenzian; LAGA & LOUWYE 2006) of Antwerp, Belgium. Unfortunately, DAVIDSON (1874b) had very limited material and illustrated only the ventral valve, but mentioned its close similarity to Rh. nigricans . CHAPMAN & CRESPIN (1923) erected a new genus Tegulorhynchia for ribbed rhynchonellids of the southern hemisphere, and some years later THOMSON (1927) attributed species nysti to Tegulorhynchia . COOPER (1959) described a new genus, Notosaria with type species Terebratula nigricans , and distinguished his new genus from Tegulorhynchia on the basis of ornamentation, beak characters and cardinalia. Cooper also studied a pedicle and a brachial valve of Rh. nysti confirming DAVIDSON’s (1874b) original observation and included this species also to his new genus, Notosaria . Later LEE & WILSON (1979) accepted and followed this opinion. The new, revised Treatise also mentioned Notosaria from Europe (Middle Miocene of Poland and Pliocene of Belgium) ( MANCEÑIDO et al. 2002) and erected the new family Notosariidae . The only Miocene record of Notosaria from Europe is an eroded and very uncertain pedicle valve from Poland ( POPIEL-BARCZYK & BARCZYK 1990).

This species has not been illustrated since DAVIDSON’s (1874b) original description (his figures were re-published by NYST 1881), although it is not rare in some Neogene assemblages. OTTEMA & IN’T HOUT (1987) probably also redrew DAVIDSON’s (1874b) pedicle valve illustrations, which is rather strange, as this species is common in the studied Kallo assemblage. VINCENT (1893) mentioned species nysti from Belgium, while DOLFUSS & DAUTZENBERG (1901) and DE MORGAN (1915) reported it from the Miocene of France (Savigné, Saint- Saturnin, Saint-Emy) without illustrations. In the studied material this species occurs in the Kreekraksluizen sample only with some valves, but it is common in some Pliocene (“Redonian”) samples of France (e.g. St. Clément-de-la Place) or in the Pliocene of Belgium (e.g. Kallo). The detailed description of both of these faunas is in progress and emended diagnosis of N. nysti will be given there.
