Three of them were found in Papua New Guinea, i.e. M. striatum n.sp. from Nanodromia elongata (Hybotidae), Meoneura sp. (Carnidae), Ephydridae sp. and Phoridae sp.; M. prostriatum n.sp. from Nanodromia spuria and M. punctatum n.sp. fropm Meoneura sp.. The fourth species, M. bruneiense n. sp. was collected from Tambemyia sp. (Dolichopodidae), in Brunei (Borneo). |
