The family Tachiniscidae was established by Kertész
for a single species, ''Tachinisca cyaneiventris'' Kertész, 1903 from Peru and Bolivia. Kertész correctly placed that family in the “Muscidae acalyptratae”, in spite of its tachinid-like appearance. In the same year, Bischof
described another genus, ''Bibundia'', with a single species, ''B. hermanni'' Bischof (from Central Africa), which he assigned to “Ortalidae”. Malloch
described one more monotypic tachiniscid genus, ''Tachiniscidia'', with the type species ''T. africana'' Malloch from “Chirinda Forest, S. Rhodesia” (Zimbabwe).
The only host data recorded for these three genera, or any other Tachiniscinae, is the mention of “''Anthophasia robertsi'' Cogan” (nomen nudum; listed by Cogan
as an undescribed species of ''Bibundia'') reared from pupae of ''Bunaea alcinoe'' Stoll and ''Imbrasia obscura'' Butler (

) by Roberts (1969). The exact identity of the host species needs further investigation, as Cogan (1980: 555) stated that “A single specimen of a Bibundia species has been reared by Roberts (1969) from a caterpillar of a saturniid moth, ''Imbrasia nictitans'' Fabricius” (=''Imbrasia epimethea'' Drury).
The genera and species currently placed in the tribe Ortalotrypetini were originally assigned to the family Tephritidae, and generally fit its diagnosis well. Hendel (1927) established the genus ''Ortalotrypeta'' with two species from China (Sichuan), ''O. gigas'' Hendel and ''O. idana'' Hendel, which he considered related to ''Acanthonevra'' Macquart and allied genera of fruit flies. Later, eight additional species from southeastern China and northern Vietnam. The genus ''Cyaphorma'' Wang 1989, very close to ''Ortalotrypeta'', was described from China (Wang, 1989). Ito (1983) established the tribe Ortalotrypetini in his key to genera of Japanese Tephritidae. He included the single genus ''Ortalotrypeta'' to separate it from genera of the tribe Acanthonevrini. The tribe was preliminarily revised by Norrbom.
McAlpine (1989) presumed that the Tachiniscidae could be a sister-group of
Pyrgotidae
The Pyrgotidae are an unusual family of flies (Diptera), one of only two families of Cyclorrhapha that lack ocelli. Most species are "picture-winged" (i.e., have patterns of bands or spots on the wings), as is typical among the Tephritoidea, but ...
