5B6287FFFFB5FFABFF3F4CAD5616FD6C.taxon	discussion	Remarks. In the keys of Borgmeier (1967), this species will run to couplet 57 of group VII on page 89, to M. claudia Borgmeier, 1967 from Australia. The new species is different from the latter in antial bristle being lower than upper supra-antennals on frons; the abdominal tergites II – V yellow with brown patches on both sides; female with 4 scutellar bristles; and also the detail of hypopygium. The female will run to couplet 29 of group VI on page 85, to M. curticilliata Borgmeier, 1967, which was only known in female. The new species differ from the latter in yellow abdominal tergites, longer costal cilia and 2 hairs on axillary margin. In the key of Disney (1989) the species will run to 212 on page 32, to M. largifrontalis Schmitz, 1939. However, the new species has no bristle between the two strong bristles on notopleuron; male abdominal tergites yellow, with brown patches on each side of tergites II – V; female abdominal tergite VI is not paler than tergiteV (see Disney 2010); hind femur yellow with dark brown tip. In the key of Buck & Disney (2001), the species will run to couplet 4 on page 79, to M. hexanophila Buck, but the latter SPS larger (0.012 – 0.031 mm) and anal tube long. If scutum color is omitted, the new species will run out at couplet 7 to the undescripted species. In Disney’s key to the males of European species of Megaselia with a notopleural cleft (Disney 2013), the new species runs to 1 on page 67, to M. hexanophila Buck. The differences are described as above.	en	Liu, Guang-Chun, Chen, Gao (2019): New Scuttle flies (Diptera: Phoridae) reared from dead Termite, Odontotermes formosanus (Shiraki, 1909) (Isoptera: Termitidae) in China.

The female will run to couplet 22 of group VI on page 85, to M. chipmanni Borgmeier, 1967, which is only known in female.
