In addition, the basal inner gradate meets Psm, the radial crossveins are sinuate and the adult gut contents were found to include insect remains; no species of Mallada has yet been found to be carnivorous. The larval morphology of Atlantochrysa also differs considerably from that of Mallada since the larvae of Mallada are debris carriers and so have long, hooked setae and cylindrical thoracic tubercles whereas the larvae of Atlantochrysa, which do not carry debris, have short setae and short, spherical tubercles. Mallada, Atlantochrysa and Anomalochrysa McLachlan are the only genera in the Chrysopidae in which males have both a tignum and a gonapsis. However, this does not necessarily indicate a close relationship between the genera since this is probably the plesiomorphic character state for the Chrysopini. There are at least 16 genera in the Chrysopini in which males have either a gonapsis or tignum and it is highly unlikely that these structures have arisen independently on several occasions. The tignum, in particular, has a very similar morphology in all the genera in which it occurs, lending weight to the hypothesis that it only arose once in the Chrysopidae. The probable.
