Cerodontha (Cerodontha) angustipennis Harrison, 1959
Similar to australis but third antennal segment shorter, wings ochre-brown. Immediately distinguishable from the other Cerodontha known to New Zealand by the brilliantly shining black mesonotum (Spencer, 1973).
IMPORTANT CHARACTERS
Adults
Wing length: 2 - 2.5 mm. Mesonotum and abdominal tergites shining with weak pubescence. Tergites rather brown, mesonotum black, somewhat bluish metallic. According to the original description only one notopleural bristle. In contrast, Spencer, 1973 reported two notopleural bristles, the material studied (von Tschirnhaus collection) show one bristle only. However, the former position of the remaining reduced bristle is still visible by a darkened scar. Legs conspicuously long, occiput extensively yellow, antennae angulate. Dorsocentral bristles: 3 with an additional small hair.
Immature stages
Unknown, but probably quite similar to Cerodontha denticornis.
BIONOMICS
Leaf miner.
HOST PLANTS
Most probably Poaceae.
DISTRIBUTION
New Zealand.
ECONOMIC IMPORTANCE
Unknown. Apparently a widespread and abundant species in New Zealand. The species was included because of the similarity to Cerodontha australis.
