Male cercal bases fused medially ( Fig. 22)................................................................................................................................. 4

4 R 4+5 dorsally with fine and widely spaced setulae on much of its length. Postpedicel with a row of setae along dorsal margin ( Fig. 18). Ground colour of abdominal tergites mainly dark brown but pale yellowish basally and narrowly whitish on hind margins. Mid and hind femora mainly dark-brown or blackish, except for yellowish apices. Only posterior coxa entirely pale yellow. Pleural sclerites of thorax varying in colour from brown to reddish .................... ..................................................................................................................................................... M. basilewskyi (Peris)

- R 4+5 dorsally bare. Postpedicel without setae. Ground colour of abdominal tergites pale reddish-yellow on about basal 2/3 or more and brown in the remaining surface. Mid and hind femurs pale yellow on about basal 3/5 and pale brown on the remaining surface. All coxae yellowish. Pleural sclerites of thorax almost entirely pale reddish-yellow ..............................................................................................................................................
