Lignicida
grisechana sp. n.
 ,  21-22mm. This is a larger species than echana
(18mm)
with grey forewings rather than rosy ochreous brown ones. The anterior half of
the distal margin of the forewing is diagnostically darkened. Males of echana
are
not available for comparison, but the abdomen is described in the generic
account. In females, the bursa of grisechana is much more elongate and narrow than in echana,
where it is oval, and the signum is more definite and in a lateral rather than
apical position. There are two conspicuous, longitudinal bands of sclerotisation
in the ductus.
