Prophalangopsidae
family of insects
The family Prophalangopsidae are insects belonging to the order Orthoptera. They are the only extant members of the superfamily Hagloidea. There is only one extant genus in North America, where they are known as grigs, four genera in Asia, and many extinct genera (see below).
The earliest fossils of the family date to the Early Jurassic around 200 million years ago, and the family exhibited great diversity between the Middle Jurassic and the Early Cretaceous, with their fossil record after that time being sparse.
The closest living relatives to the Prophalangopsidae are the family Tettigoniidae (katydids or bush-crickets), but the evolutionary split occurred more than 230 million years ago in the Permian.
The female of the species consumes the wings of the male during mating.
Haglidae is often used as a synonym of the family, but is used to refer to a distinct grouping of extinct hagloids by paleontologists.
Subfamilies and genera
The Orthoptera Species File lists the following: Archibald, Gu, and Mathewes (2022) removed the genera †Albertoilus and †Palaeorehnia from the family, moving them to a revised †Palaeorehniidae which they considered unplaced as to superfamily.
This brief starts where responsible research should: with the source description of “Prophalangopsidae” as family of insects. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as family of insects. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q389762. The first chronological checks are 2022.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
