Diagnosis. The forewing length is 15.5–16.0 mm in males and 18.0–19.0 mm in females. Tarika reducta sp. n. differs from most of the congeners in its smaller size and is most similar to T. biserratula sp. n., from which, however, the new species differs in the somewhat broader forewing in both sexes. The male genital capsule of T. reducta sp. n. is reminiscent of T. varana , T. annapurna sp. n. and T. erlanga sp. n. but distinguished by the somewhat longer and more upcurved claw-shaped distal section of the distal saccular process. The vesica of T. reducta sp. n. differs clearly from other congeners in the shorter distal diverticulum and thinner spiniform cornuti in the subbasal cluster. The female genitalia of the new species are distinguished from T. varana and T. erlanga sp. n. by the broader and more gelatinous ductus bursae with a medial constriction.

Distribution. North Thailand (Chiang Mai and Lampang Provinces).

Etymology. The specific epithet refers to the reduced distal diverticulum in the male phallus vesica, which is the shortest in the genus. The name is a noun in the nominative singular in apposition.
