New records of two species of Cecidomyiidi (Cecidomyiidae: Diptera) from the restingas of the Brazilian Amazon coast and description of a new species of Meunieriella Kieffer, 1909 (Lasiopteridi: Alycaulini)

In Brazil, restingas are among the best-studied ecosystems for gall richness and their inducers. However, knowledge of this diversity in the Amazon region remains limited. Based on gall collections conducted in restinga areas in the state of Pará, Brazil, Dactylodiplosis heptaphylli Maia, 2004, and Lopesia grandis Maia, 2001 are recorded for the first time on the Amazonian coast. The associated fauna was characterized, with representatives of Eurytomidae, Pteromalidae, and Platygastridae (Hymenoptera) identified as possible parasitoids of the gall inducers. Additionally, a new species of Meunieriella Kieffer, 1909 is recognized as an inquiline in galls induced by L. grandis on Dalbergia ecastaphyllum (L.) Taub. (Fabaceae). Meunieriella minor Cunha, Melo and Santos sp. nov. is formally described based on morphological characters of larvae, pupae, and adults (male and female), including diagnosis and illustrations.The ZooBank LSID is: zoobank.org:act:5E8575E6-23E7-4239-B657-AAF078232B47.
