E-mail: nilton.j.s.monteiro@gmail.com Abstract We here report 35 Agromyzidae species and their associations with host-plants in the state of Pará. We describe the new species Ophiomyia falcifera sp. nov. and Phytomyza varronivora sp. nov. Eleven species, and the genera Phytomyza Fallén and Pseudonapomyza Hendel, are reported for the first time in Brazil. Key words: leaf miner fly, distribution, taxonomy, Amazon Introduction The family Agromyzidae contains approximately 2800 described species (Boucher 2010), over 450 of which occur in the Neotropical Region (Martinez & Etienne 2002). Sousa & Couri (2018b) listed approximately 90 Agromyzi- dae in Brazil, most of which are found in the south and southeast. Many Agromyzidae species feed in leaf tissue, creating “mines” visible on the surface of the leaf (Spencer 1973a). However, several species feed on other plant parts such as stems, flower heads, and seeds by boring into the tissues or producing galls (Spencer 1973a). Approxi- mately 150 botanical families have host-plants attacked by Agromyzidae species (Benavent-Corai et al. 2005). Agromyzidae are poorly studied in the Neotropical region, and perhaps for that reason, they have been cited as an example of a taxon with a decreasing trend in numbers of species from temperate to tropical regions (Price 1988; Hawkins 1990). However, some studies have revealed a significant number of species in the Neotropical region, e.g. Spencer (1963), Spencer & Stegmaier (1973), Spencer et al. (1992), and Sasakawa (1992a; 1992b; 1992c; 1992d; 1994;), including several species recorded in Brazil. More recently, studies by Sousa & Couri (2013; 2014; 2017a; 2017b; 2018a) have provided more updated information on species present in Brazil. Esposito (1994) is an important study about Agromyzidae species present in the Brazilian Amazon, more spe- cifically in Marajó Island, Soure, state of Pará, and it included the description of Calycomyza ipomoensis Esposito 1994. Subsequent studies have been published on species collected in the states of Pará and Rondônia, including Monteiro et al. (2015), Monteiro & Esposito (2017), Carvalho-Filho et al. (2016), and Sousa & Couri (2017a; 2017b; 2018a), with a total of 24 Agromyzidae species recorded in the Brazilian Amazon, eight of which occur in Pará state (Sousa & Couri 2018b). However, this limited number is probably due to the scarcity of studies in the region. The purpose of the present paper is to provide information on Agromyzidae species and their host-plants in some localities in the state of Pará, and to describe two new species in Brazil. Additionally, we report Phytomyza Fallén and Pseudonapomyza Hendel in the country for the first time. Material and methods The specimens analyzed were derived from samples collected in the municipalities of Belém and Paragominas (Pará state) from 2013 to 2018, and from material deposited at the Entomological Collection of Museu Paraense Emílio
