The only species known in the genus Pseudalypia
is P. crotchii and is so different from other acontiines that
it was described in the Agaristinae. The moth is unmistakable
and is reminiscent of an arctiine because of the contrasting orange
prothoracic collar. The male genitalia are most similar to those of
Spragueia, but the valves are almost bilaterally symmetrical,
except for the larger ampulla on the right valve. The vesica has two
large subapical diverticula covered with spines. The female genitalia
are similar to those of Tarache and have a large sclerotized
appendix
bursae that extends anteriorly part way down the right side of the corpus
bursae.
Pseudalypia crotchii has been reared
from Malvastrum exile and M. parviflora in
the family Malvaceae.
