THE NEARACTIC SAWFLIES OF THE DINEURA COMPLEX1 (HYMEN.: TENTHREDINIDAE)
Published online by Cambridge University Press: 31 May 2012
Extract
The nematine genus Dineura has had assigned to it at various times several species of nearctic sawflies. A close study of these species indicates that Dineura itself is not represented in our fauna, but instead three genera which resemble it in wing venation. This complex was considered by MacGillivray as the sub-family Dineurinae, but as pointed out by Rohwer it is in reality part of the Nematinae. The three genera involved may be separated from the other Nematinae by having the front wings with the base of vein 2A and 3A absent and the second radial cross-vein (2r) present. The extreme differences between the genera suggest strongly that the segregate is purely an artificial one based only on accidental similarity in venation.
