    The genus Lingulapholis had temporal and spatial restrictions during the Devonian, being found only in Colombia and the United States. In Brazil, its related taxa Craniops is common in the Amazonas, Paraná, and Parnaíba basins. New data from the cities of Picos and Itainópolis, east flank of Parnaíba Basin, led to the discovery of a yet previously undescribed brachiopod genus for this region of Gondwana. The Lingulapholis brachiopod was found associated with plant fragments under conditions of moderate to low hydrodynamic energy as indicated by ichnological assemblage, in proximal expressions of Cruzianaichnofacies alternated to Skolithos ichnofacies. The presence of Lingulapholis suggests that the Parnaíba Basin was inserted in the zone of diffuse faunal mixing during the Middle Devonian

    O gênero Lingulapholis teve restrições temporais e espaciais durante o Devoniano, sendo encontrado apenas na Colômbia e nos Estados Unidos. No Brasil, seu táxon relacionado Craniops é comum nas bacias do Amazonas, Paraná e Parnaíba. Novos dados das cidades de Picos e Itainópolis, flanco leste da Bacia do Parnaíba, levaram à descoberta de um gênero de braquiópode ainda não descrito para esta região do Gondwana. O braquiópode Lingulapholis foi encontrado associado a fragmentos de plantas em condições de moderada a baixa energia hidrodinâmica, conforme indicado pela assembleia icnológica, em expressões próximas de icnofácies Cruziana alternadas a icnofácies Skolithos. A presença de Lingulapholis sugere que a Bacia do Parnaíba esteve inserida na zona de mistura faunística difusa durante o Devoniano Médio
