Systematic and biological notes on some brachycerous
Diptera of Southern Rhodesia.
Teskey (1981) mentions that some brachycerous
larvae use their mouth hook as an anchor to facilitate locomotion; perhaps a hatchet-like labrum would provide a better anchor than a hook-like labrum in decaying, chewed up plant matter and frass.
Nestling diets were composed of 44.28% Brachycerous
Diptera, 12.5% Nematocerous Diptera, 12.0% Homoptera, 14.5% Hymenoptera and 7.6% Coleoptera.
The family Stratiomyidae belongs to the brachycerous
Diptera and comprises more than 2600 world-wide species within 375 genera (Woodley 2001).
He further proposed a revised terminology for components of the brachycerous antenna and suggested that the emergence of the Brachycera from nematocerous ancestors involved coevolution of antennal transformation and pseudotracheate labella, linked to a new feeding mode appropriate in new floras that appeared in the Triassic and Jurassic (Stuckenberg 1999).
In 1960 I described Lampromyia namaquensis [Stuckenberg 1960: 228] as the only known brachycerous fly with five radial veins.
The genus Dirhinus (Chalcididae) has been reported as a pupal parasite in Brachycerous
Diptera widely distributed throughout the world tropics, with 3 known species in the USA (Burks 1947), and about 15 native species yet to be studied in regions ranging from Indiana (USA) to central Argentina (Boucek 1992).
