Tribe Limnophorini Villeneuve, 1902

Species representing 12 out of a total of 24 currently recognized genera ( Table 1 ) were examined.

• Andersonosia Emden, 1940 , Camptotarsopoda Strand, 1913 , Heliographa Malloch, 1921 , Limnophora Robineau-Desvoidy, 1830 , Lispe Latreille, 1797 , Lispoides Malloch, 1920 , Neolimnophora Schnabl, 1902 , Pachyceramyia Albuquerque, 1955 , Villeneuvia Schnabl & Dziedzicki, 1911

All examined species from these nine genera show the prevalent muscid state A4, in which vein C is bare dorsally and extensively setulose ventrally: Andersonosia velutinifrons (Malloch, 1928) , Camptotarsopoda (3 spp), Heliographa (6 spp), Limnophora (30+ spp), Lispe (30+ spp), Lispoides aequifrons (Stein, 1898) , Neolimnophora maritima (Röder, 1887) , N. virgo (Villleneuve, 1906) , Pachyceramyia pantherina (Wiedemann, 1824) and Villeneuvia aestuum (Villeneuve, 1902) .

Deviations from state A4 are unusual among limnophorine genera, but involve examples of both loss of ventral setulae and gain of dorsal setulae.

• Spilogona Schnabl, 1911

Examination of 40+ species of Spilogona revealed that the prevalent muscid state A4 is the rule in this large genus, but Michelsen (2021) described S. maderensis from Madeira ( Portugal), which exceptionally is setulose dorsally on vein C (state A8).

• Tapantiomyia Michelsen, 2017

The only species, Tapantiomyia enigmatica Michelsen, 2017 , is in the male sex (female unknown) unique among Coenosiinae (Michelsen 2017: fig. 6) by the absence of ventral costal setulae, state A0, and further deviates from other Muscidae by the inflated CS1, which is bare except for a single anterior row of tiny, pale setulae.

• Thaumasiochaeta Stein, 1911 ( Fig. 17A–B )

The examined four species of Thaumasiochaeta are setulose on the dorsal side of CS1 (state A5).
