Bigot, Symmictus Loew and Parasymmictus Bigot should 
all be united with Trichopsidea, these names being hardly 
worth retaining, even in a subgeneric sense. 
The six genera may be tabulated as follows: 
1. Ocelli absent. Alula vestigial Atriadops. 
Ocelli distinctly developed 2. 
2. Alula well developed, though narrower than usual ... 3. 
Alula vestigial or absent 4. 
3. Neither the third nor the fourth longitudinal veins 
branched; cross-veins present between second and 
third, and between first and second longitudinal veins ; 
the whole forming two marginal, two submarginal, 
and only four posterior cells. Hind margin of wing 
more or less wavy. Hind femora swollen toward 
apex Nycterimyia. 
Both third and fourth longitudinal veins forked, the 
branches ending freely in the apical margin; cross- 
vein absent between first and second, present between 
second and third longitudinal veins ; the whole form- 
ing one marginal, three submarginal, and five pos- 
terior cells. Hind margin of wing not wavy 
Ceyloniola. 
4. Antennal style much flattened, leaf-like at apex. Wing 
of normal shape Cyclopsidea. 
Antennal style slender, or very slightly expanded at 
apex 5. 
5. Wing much narrowed toward the base, more or less 
club-shaped. Hind femora and tibiae swollen api- 
cally Nycterimorpha. 
Wing of normal shape, not or scarcely narrowed to- 
ward the base. Femora and tibiae not appreciably 
swollen Trichopsidea. 
Cyclopsidea Mackerras (1925) contains only one species, 
of Queensland. One species of Trichopsidea occurs in New 
Guinea, Australia and Tasmania; and since the genus is 
otherwise known from the Mediterranean Subregion, the 
Ethiopian Region and North America, it will probably be 
found in the Oriental Region also.
