Calamoceratidae Ulmer

Calamoceratinae Ulmer, 1905: 80 [as subfamily of Leptoceridae ]; type genus: Calamoceras Brauer, 1865 . Calamoceratidae Ulmer, 1906: 46 [as distinct family]

The individuals are mostly large, stout-bodied, and frequently with broad wings. Ocelli are absent. The cranial suture is invisible, but according to Prather (2004) a more or less developed posteromesal ridge forms a synapomorphy for the family. There are grooves present on the facial-cranial region and the occipito-postgenal groove is also visible, at least on species in Anisocentropus . The maxillary palps have 5 or apparently 6 segments. The antennae are much longer than the forewings. Similar to Leptoceridae and Molannidae , the mesoscutum has a pair of longitudinally extended, diffuse, or fragmented setal warts. The wing venation is complete, without sexual dimorphism. The discoidal, median, and thyridial cells are present and closed in the forewings. Tibial spurs are 2, 4, 2-4. Males have no intermediate appendages or phallic parameres. In most species there are 2 pairs of setose areas on segment IX, 1 dorsolateral, the other ventrolateral or ventral, with the number and length of setae are species-specific.
