Europlema bilobuncus sp.n.
 
9mm. The facies is somewhat as in desistaria, with a rusty brown
area to the hindwing and a white patch interior to the forewing submarginal,
albeit smaller, that recurs below weakly. The submarginal lunules are arcuate
rather than irregular. The pale discal mark is strong, transversely linear
within a generally dark brownish zone. The male genitalia have the uncus
distally somewhat bibbed, with further weak lobes just distal to the almost
filamentous arms of the gnathus: setae are restricted to these distal and basal
lobes. The valves are rather long, narrow, roundedly triangular, the ventral
processes short, evenly curved. The female has a single signum set basally,
transversely bibbed. The ductus is relatively long, and there is no junction at
the forewing point of the ductus seminalis.
