This species was based on a hind wing, which lacked the apex; 
the type could not be found in the collection of the Institut and the 
figure included here was made from Dr. Carpenter’s photograph. 
This species represents the most specialized one within the genus 
Microdictya. The development of veins along the costal area is 
very advanced and the outline of the hind wing, recalling some 
species of the related genus Stenodictya , has a pronounced convex 
curvature of the posterior margin in the apical half. At the same 
time, the proximal half of the wing retains the oval shape charac- 
teristic of other species of the genus. 
Hind wing: length 50 mm, width 14 mm. Wing broadest shortly 
before mid-wing. Anterior margin convex near the base, slightly 
concave at about mid-wing. Posterior margin concave in proximal 
half, then forming a pronounced convex curvature at the end of the 
first branch of MP. Apex apparently directed backward. Rs long, 
originating before the first third of the wing length. MP and CuP 
giving off two branches. Anal area long and narrow, with four
