Froghopper with very local distribution, confined to coastal saltmarshes in south east England.
Records from Thames estuary saltmarshes
Distribution records as at May 2019
Neophilaenus longiceps has a very local distribution limited to coastal saltmarshes in south east England. Adults are 6 - 7mm long and can be seen in June.
As is typical with froghoppers, they have two stout spines on the outer edge of the hind tibia, as well as several smaller spines at the tip.
Neophilaenus species can be distinguished from Philaenus spumarius by the straight outer edge to the wings (they do not curve outwards when seen from above as is the case for Philaenus). They are distinguished from Aphrophora species by the vertex plate (top of the head) NOT having a median keel i.e. the top of the head is flat, there is no ridge running down the midline of the head.
Neophilaenus longiceps is very similar to the common Neophilaenus lineatus. It can be distinguished by the central vertex 'plate' on the top of the head, which is longer than it is wide (on Neophilaenus lineatus, this plate is wider than it is long). Neophilaenus longiceps also tends to be a bit bigger as well as being restricted to saltmarshes.
