Norwegian Journal of Entomology 65, 32–48. The present paper is the last in a series of four on the fauna of Agromyzidae in Norway, and deals with the genera Melanagromyza Hendel, 1920, Ophiomyia Braschnikov, 1897, Amauromyza Hendel, 1931, Aulagromyza Enderlein, 1936, Cerodontha Rondani, 1861, Chromatomyia Hardy, 1849, Liriomyza Mik, 1894, Metopomyza Enderlein, 1936, Napomyza Westwood, 1840 and Phytomyza Fallén, 1810. Ninety-six species are reported of which seventeen are reported new to the Norwegian fauna: Melanagromyza aeneoventris (Fallén, 1823), M. cunctans (Meigen, 1830), M. pubescens Hendel, 1923, M. submetallescens Spencer, 1966, Ophiomyia curvipalpis (Zetterstedt, 1848), O. ranunculicaulis Hering, 1949, Chromatomyia syngenesiae Hardy, 1849, Metopomyza interfrontalis Melander, 1913, M. xanthaspioides (Frey, 1946) , Phytomyza cecidonomia Hering, 1937, P. cirsii Hendel, 1923, P. clematidis Kaltenbach, 1859, P. fennoscandiae Spencer, 1976, P. isais Hering, 1937, P. origani Hering, 1931, P. pulsatillae Hering, 1924 and P. socia Brischke, 1881. In addition, new regional data is given for eighty species previously reported from Norway. The biology of the larva, when known, and the distribution in Norway and Europe are commented on species new to Norway. The Norwegian checklist for Agromyzidae now consist of 256 species.

Introduction fourth in a series on the fauna of Agromyzidae in Norway (Andersen 2012, 2013, 2016), and The larvae of Agromyzidae mine in leaves, presents new data from the genera Melanagromyza stems, seeds and roots of plants. Accordingly, Hendel, 1920, Ophiomyia Braschnikov, 1897, many Agromyzidae species are important pests Amauromyza Hendel, 1931, Aulagromyza in cultural plants. During the last 25 years, some Enderlein, 1936, Cerodontha Rondani, 1861, data have been published on the Norwegian fauna Chromatomyia Hardy, 1849, Liriomyza Mik, of Agromyzidae (Andersen & Jonassen 1994, 1894, Metopomyza Enderlein, 1936, Napomyza Bland 1995, Bland & von Tschirnhaus 1998, Westwood, 1840 and Phytomyza Fallén, 1810.
