Periscelididae are small flies, 3–4 mm long. The head is distinctly broader than high and the cheek is broad and bulging posteriorly. The postocellar bristles are present and diverging. The ocellar bristles are present, there are two orbital bristles on each side of frons, the anterior orbital bristle is directed forward and towards the median line. There is one pair of frontal bristles, curving backward. Interfrontal bristles are absent. Vibrissae (a row of vibrissa-like bristles) are well developed. On the mesonotum there are two pairs of dorsoscentral bristles. The costa is continuous (not interrupted), the subcosta is incomplete. The posterior basal wing cell and discoidal wing cell are fused and the anal vein does not reach the margin of the wings. The wing is clear or milky or with infuscated spots. Tibiae are usually banded and without dorsal preapical bristles.
These 12 genera belong to the family Periscelididae:

The family Sciomyzidae belongs to the typical flies (Brachycera) of the order Diptera. They are commonly called marsh flies, and in some cases snail-killing flies due to the food of their larvae.
The Sepsidae are a family of flies, commonly called the black scavenger flies or ensign flies. Over 300 species are described worldwide. They are usually found around dung or decaying plant and animal material. Many species resemble ants, having a "waist" and glossy black body. Many Sepsidae have a curious wing-waving habit made more apparent by dark patches at the wing end.
The Anthomyiidae are a large and diverse family of Muscoidea flies. Most look rather like small houseflies. Most species are drab grey to black. Many Pegomya are yellow, and some members of the genera Anthomyia and Eutrichota are patterned in black-and-white or black-and-silvery-grey. Most are difficult to identify, apart from a few groups such as the kelp flies that are conspicuous on beaches.
The Scathophagidae are a small family of Muscoidea which are often known as dung flies, although this name is not appropriate except for a few species of the genus Scathophaga which do indeed pass their larval stages in animal dung. The name probably derives from the yellow dung fly, which is one of the most abundant and ubiquitous flies in many parts of the Northern Hemisphere.
The Lauxaniidae are a family of acalyptrate flies. They generally are small flies with large compound eyes that often are brightly coloured in life, sometimes with characteristic horizontal stripes, such as in Cestrotus species. Many species have variegated patterns on their wings, but in contrast they generally do not have variegated bodies, except for genera such as Cestrotus, whose camouflage mimics lichens or the texture of granitic rocks.
The Lonchaeidae are a family of acalyptrate flies commonly known as lance flies. About 500 described species are placed into 9 genera. These are generally small but robustly built flies with blue-black or metallic bodies. They are found, mainly in wooded areas, throughout the world with the exception of polar regions and New Zealand.
The Chamaemyiidae are a small family of acalyptrate flies with less than 200 species described worldwide. The larvae of these small flies are active and predatory and are often used for biological control of aphids, scale insects, and similar pests. Chamaemyiid fossils are poorly represented in amber deposits, but a few examples are known from the Eocene epoch onwards.
Asteiidae is a small but widespread family of acalyptrate flies or Diptera. About 130 species in 10 genera have been described worldwide. They are rarely collected.
Canacidae, incorrectly Canaceidae, or beach flies, surf or surge flies, is a family of Diptera. As of 2010, 307 species in 27 genera. The family now includes Tethininae as a subfamily.
The Coelopidae or kelp flies are a family of Acalyptratae flies, they are sometimes also called seaweed flies, though both terms are used for a number of seashore Diptera. Fewer than 40 species occur worldwide. The family is found in temperate areas, with species occurring in the southern Afrotropical, Holarctic, and Australasian regions.
Diastatidae are a family of flies in the order Diptera. They are encountered primarily in the Holarctic Region, but several species are found in the Oriental, Neotropical and Australasian regions. Members of the family number over 20 described species in three genera. There is an additional fossil genus.
The Platystomatidae are a distinctive family of flies (Diptera) in the superfamily Tephritoidea.
Aulacigastridae is a very small family of flies known as sap flies. The family Stenomicridae used to be included within this family, but was moved by Papp in 1984. They are found in all the Ecoregions.
Platystomatinae is a subfamily of flies (Diptera) in the family Platystomatidae that includes 80 genera, the largest subfamily with at last estimate, c. 900 species globally.
Cyamops is a genus of flies.
The family Pseudopomyzidae comprises minute to small (1.7-5.5 mm), dark-coloured acalyptrate flies; formerly they have been treated as a subfamily of Cypselosomatidae
Periscelis is a genus of flies in the family Periscelididae. There are about 15 described species in Periscelis.
Stenomicra is a genus of flies in the family Periscelididae. There are more than 20 described species in Stenomicra.
Hyadina is a genus of shore flies in the family Ephydridae.
