Conservazione: Lugubria ternetzi è valutata dalle organizzazioni internazionali di salvaguardia delle specie a rischio come (LC) basso rischio (2020). This species is common in many sites along most of the length of the Oyapock River, but this species occurs in some areas impacted by gold mining, which may pose a risk to it (Taphorn & Rodríguez-Olarte, 2022).
