Orvasca brunneva sp. n.
8-10mm. The facies is like a darker, browner, version of that of eva,
but with the distal border of the dark area of the forewing clearer and with
a definite central projection. The hindwing yellow border is narrow, more or
less restricted to the fringes. The uncus of the male genitalia is long, with
neither a rugose protrusion nor a bifid structure. The valves are similar to
those of rufalba, and the saccular flap is also well developed and setose,
though straight and narrow, rather than sinuous.
