Eucinetidae is a family of beetles, notable for their large coxal plates that cover much of the first ventrite of the abdomen, sometimes called plate-thigh beetles. The family is small for beetles, with about 50 species in 11 genera, but are found worldwide.
Anthribidae is a family of beetles also known as fungus weevils. The antennae are not elbowed, may occasionally be longer than the body and thread-like, and can be the longest of any members of Curculionoidea. As in the Nemonychidae, the labrum appears as a separate segment to the clypeus, and the maxillary palps are long and projecting.
Tachysphex is a genus of square-headed wasps in the family Crabronidae. There are at least 440 described species in Tachysphex.
Hydrochus is a genus of water scavenger beetles in the family Hydrochidae, formerly placed in the Hydrophilidae. The name Hydrochus has also been used for a fly genus in the family Dolichopodidae. This junior homonym is a junior subjective synonym of the genus Rhaphium.
Brachys is a genus of metallic wood-boring beetles in the family Buprestidae. There are at least 140 described species in Brachys.
Chrysobothris is a genus of metallic wood-boring beetles in the family Buprestidae. There are at least 690 described species in Chrysobothris.
The Ropalomeridae are a family of acalyptrate flies.
The Aphrophoridae or spittlebugs are a family of insects belonging to the order Hemiptera. There are at least 160 genera and 990 described species in Aphrophoridae.
The Cryptochetidae are a small family of tiny flies. Some twenty to thirty species are known. Generally they are metallic blue black, stoutly built, with the head broad and high and with clear wings. Like other species in the superfamily Lonchaeoidea, the Cryptochetidae have antennae with a cleft in the second segment. Unlike practically all Schizophora however, they lack an arista, or if they do have one, it is too small to distinguish with any confidence. The family name refers to this unusual distinction; "Cryptochetidae" literally means "those with hidden bristles". The adult flies also are unusual among insects in that they have only a single pair of abdominal spiracles — this is not a serious physiological challenge in such small insects.
Schizopteridae is the largest family in the infraorder Dipsocoromorpha and comprises 56 genera and approximately 255 species. Schizopterids are some of the smallest (0.5–2.0 mm) true bugs. Members of this family can be distinguished by their small size, enlarged forecoxae and varying degree of abdominal and genitalic asymmetry in males. Schizopteridae exhibit a wide range of simple and complex wing venation patterns–some species even possess true elytra. The group is currently divided into three subfamilies: Schizopterinae, Ogeriinae and Hypselosomatinae.
Coreini is a tribe of leaf-footed bugs in the family Coreidae. There are at least 20 genera and 70 described species in Coreini.
