Mniothripa fletcheri sp. n.


Mniothripa fletcheri

8mm. The forewings are a more uniform, darker grey than in the previous species, and lack a forewing tornal spot; the hindwings are not translucent. The male genitalia have valves with a rather square apex and a small dorsal lobe (rounded, unlobed in bradleyi), and the setae are much as in lichenigera (more uniformly coarse in bradleyi). The apical portion is separated from the rest of the valve by a curved, transverse ridge. The setae on the sacculus are reduced to a small patch of scobination, whereas in bradleyi they are more robust and extend in an elongate zone along the dorsal edge. The aedeagus is long, the vesica full of deciduous spicules as in bradleyi, but these are longer, more uniform in width. Females are not known unless the following is referable, but the facies is not a good match.
