Abstract
The species and genera of the Megarthropsini are revised. Descriptions and illustrations of the genera and species and keys for identification are presented. Lacvietina, a new genus, with four new species is described. Three of the new species, L. aurora, L. copiosa, and L. cuprina, are from Vietnam, and the fourth, L. paricosta, is from Malaysia and Thailand. Lacvietina punctatissima (Hayashi), from Taiwan, is a new combination and was transferred from Tachinus. A new species of Nepaliodes, N. solangelae from Thailand and China, is described. Seven new species of Megarthropsis are described; six of them, M. deverra, M. durga, M. empusa, M. frazerensis, M. parca, and M. smetanai, are from Malaysia; the seventh, M. djawaensis, is from Indonesia. A phylogenetic analysis supports Megarthropsini as a monophyletic tribe with Deropini as its sister group. Within Megarthropsini, Peitawopsis is the most basal genus to the remaining three genera, and Lacvietina is the sister group to Megarthropsis and Nepaliodes. The tribe is most readily distinguished from other taxa of the Tachyporinae by the densely and coarsely punctate body. Finally, the type species of Paratachinus, P. laticollis Cameron, is redescribed and discussed. Lacvietina takashii is a new combination.
