Orvasca brunneva sp. n.  

Orvasca brunneva (holotype)

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.
