Material. Holotype, male, Sierra Leone (Major Bainbridge) ( NHMUK). Individual photo number NHMUK 012832461 . Slide number NHMUK 010315494 .

Description. Length of fore wing 24 mm. Wingspan – 53 mm. Antenna bipectinate in proximal half, serrated in distal half. Thorax and abdomen covered with light scales. Due to the damage of the specimen it is impossible to give a full external description. Fore wing light-brown, pattern of brown spots along costa and cubitally, bright large brown spot between veins CuA 2 −CuP, sputtering of brown scales throughout wing area. Hind wing light-brown with dense sputtering of grey scales throughout wing area.

Male genitalia. Uncus long, slightly narrowing apically, apex semicircular; tegumen robust; gnathos arms basally thick, apically narrow, short, not fused; valve wide, costal and abdominal edge wavy, apex wide, rounded; juxta robust, saddle-like, two long lateral processes with spatulately widened apices; saccus massive, semicircular; phallus thick, slightly shorter than valve, curved in middle third, longitudinal folding on lateral surface of phallus, large finger-like cornutus in lateral surface of vesica.

Female unknown.

Diagnosis. The new species differs from the known representatives of the genus by its light-yellow wings and strongly widened lateral processes of the juxta.

Distribution. Known only from Sierra Leone.

Etymology. New species named after J.W. Schoorl, my friend and colleague who left the real world early, the author of the world's first scientific revision of Cossidae in the world fauna.
