The distribution range of several species extends to other countries, as far as West Malaysia, the Philippines, the Solomon Islands and northern Australia.

The species can be recognized by their white and powdered forewings which are carried in a roof-like position when the insects are at rest.

[2] Type species: Dichotropis amboinensis Muir, 1913[1] - synonym: Decora vettius Fennah, 1970[3][2] The species of Dichotropis are found on the island of New Guinea, including the western, Indonesian part and surrounding islands like New Ireland and New Britain.

This includes the type species Dichotropis amboinensis which occurs in different parts of New Guinea, New Britain, New Ireland, and in other regions, as far north as southern Luzon in the Philippines, east-central Indonesia (Ambon and Larat Island), Darwin (Northern Territory) in Australia, as well as in parts of the Solomon Islands.

[1][3][4][2] Similarly, Dichotropis peregrina has a wide distribution range from different parts of New Guinea, to Borneo, Singapore and West Malaysia.

Like in Rhotana the forewings are very broad and the adult hoppers have a size of 5–6 mm from head to the tip of the wings.

[4][2] Another important feature are the ridges at the sides of the face and vertex, the facial carinae, which are separated and do not meet in front of the eyes.

It is assumed that the nymphal stages live in decaying organic matter like other derbids, feeding on fungi.
