E-mail: lpapp@nhmus.hu Abstract - Shatalkinella gen. n. (type species: Shatalkinella marginata sp. n.) and thirteen new species of the tribe Trigonometopini BECKER, 1905 are described mainly from Southeast Asia: Diplochasma australis sp. n. (Australia), Luzonomyza pseudoforficula sp. n. (Thailand), L. sasakawai sp. n. (Vietnam, Thailand), L. vietnamensis sp. n. (Vietnam), Maquilingia biroi sp. n. (Papua New Guinea), M. thaii sp. n. (Thailand), Protrigonometopus ornatus sp. n. (Vietnam), Protrigonometopus shatalkini sp. n. (Taiwan), Shatalkinella marginata sp. n. (Thailand), S. punctipennis sp. n. (Thailand), S. ronkayi sp. n. (Taiwan, Thailand), S. thailandica sp. n. (Thailand), Tetroxyrhina peregovitsi sp. n. (Taiwan). A key for the genera of Trigonometopini of the Old World is given. Sauteromyia MALLOCH, 1927 is reinstated as a subgenus of Diplochasma KNAB, 1914. Tetroxyrhina HENDEL, 1938 is elevated to the generic rank. With 75 figures. Key words - Lauxaniidae, Trigonometopini, Shatalkinella gen. n., new species, taxonomy, Oriental and Australasian regions. INTRODUCTION The family Lauxaniidae has classically been divided into two subfamilies, Homoneurinae and Lauxaniinae. While there are some synapomorphies, which underline monophyly of the species of Homoneura sensu lato and some other related genera (not necessarily all the genera relegated today to Homoneurinae), there are no true synapomorphies (but negations to the homoneurine characters) for the subfamily Lauxaniinae. We think of a strategy * This study was supported by the Hungarian National Scientific Research Fund (OTKA, No. T042540 and K 60593).
