Characteristics

Characteristic to Histeroidea are an accessory posterior ridge (locking device) behind the hind margin and presence of medial loop and apical hinge of wing. Elytra truncate, 1 or 2 abdominal segments visible, abdominal 8th segment completely invaginated in the 7th segment. Antennae have 8 (seldom 7) segments preceding a club of fused segments. Ventral body surface glabrous.[1]

Systematics

Some authors treat Histeroidea as a single family within the superfamily Hydrophiloidea (Hydrophiloidea sensu lato), as they seem to form a clade.[2] Three families are currently recognized:

gollark: Flea eggs are discrete entities.
gollark: Actually, nothing lighter than flea eggs exists whatsoever.
gollark: *But* I also don't want it to unnecessarily add `bee/` to stuff if I just do `cyclogon -cf test.cyc bee` (to recursively add the `bee` folder).
gollark: I basically want to be able to say `cyclogon -cf test.cyc bee/apioform.txt bee/apiary.txt` and have it put in `bee/apioform.txt` at the path `bee/apioform.txt` in the archive.
gollark: <:BEES:825515690613145610> this, *why* am I having significant trouble just implementing a nice frontend for the compressional apiaries?
