Lateral paleae fascicle intergrading smoothly with main paleae fascicle; distinctive group of asymmetrical, ornate median paleae interlocking at mid-dorsal line forming smooth convex ridge. Falcigerous inferior neurosetal blades, short. broad, non-dentate. curved with blunt tip. […] Arichlidon differ from all other chrysopetalid genera in posessing a relatively short, broad body form, a lateral paleae fascicle that intergrades with the main paleae fascicle and a distinctive group of asymmetrical ornate median paleae that interlock at the rnid-dorsal line forming an arched smooth convex ridge. The shape of the falcigerous inferior neurosetal blade, short, broad, non dentate and curved with a blunt tip, are diagnostic of the genus” [details]Etymology author: "Arichlidon is a combination of the Greek ari, meaning "highly", and chlidon meaning "ornamentation', and refers to the raised rib sculptured with large cusps down the length of the superior surface of paleae.
