Abstract:
The adults, puparium and 3rd instar larva of a dung-breeding fly, Musca nevilli sp. nov. are described in the subgenus Eumusca. The adults are characterized by 4 dark postsutural mesonotal vittae, 1-2 bristles dorsally on the stem vein, the hairs on the ventral surface of r4+5 confined to the vein base, and the predominantly orange yellow tergite I+ II. The species is compared with other southern African species of the subgenus, especially with Musca xanthomelas Wiedemann, 1824, which it resembles to some extent.
