Type material. Holotype. [ CHINA] ♁, Hubei province, Zhuxi County, Shuangping village (31.57 °N, 109.87 °E), alt. 1201 m, 4 July 2017, leg. Qi W.D. et al., genitalia slide no. ZAH19022 .

Diagnosis. Acroclita ovata sp. nov. is similar to A. elaeagnivora Oku, 1979 in appearance, but it can be separated by the long, horn-shaped socii; the sacculus lacking a blunt terminal projection and the sacculus angle strongly protrudent, produced into a digitate process; and the ovoid cucullus about 1.5 times as long as wide. In contrast, in A. elaeagnivora the socii are arm-like and curved; the sacculus bears a blunt terminal projection and the sacculus angle is not protrudent; and the cucullus is about twice as long as wide.

This species is also similar to Acroclita liui Zhang & Li, 2017 , with similar socii, but it can be separated by the forewing with a basal patch, a median fascia, and an ocelloid patch; uncus drooping, represented by a pair of haired processes; the sacculus angle strongly protrudent and produced into a digitate process; and the cucullus ovoid, about 1.5 times as long as wide. In A. liui , the forewing has fasciae and ill-defined patches; the uncus is short, drooping, and haired, similar to a transverse band; the sacculus angle is not protrudent; and cucullus is oblong, about 3 times as long as wide.

Adult ( Fig. 1 ). Head: Vertex with grayish scales; frons gray. Antenna light brown. Labial palpus gray, third segment slightly drooping. Thorax: Dorsum and tegula gray. Forewing length 5.0 mm; elongate triangular, ground color gray mixed with brown scales; apex brown; termen bordered by brown scales; basal patch indistinct, from costal 1/4 to 1/3 of dorsum, outer margin protrudent, anterior part brown, other part gray; median fascia extending from costal halfway to before tornus, interrupted at median section; ocelloid patch nearly rectangular, brown in middle, silvery gray scales located on inner and outer sides, above it an elongate triangular brown patch; costa with four pairs of white strigulae from middle to apex, separated from each other by dark gray scales; anterior three pairs of strigulae extending obliquely to termen; the last strigulae composed of only one short stria, extending to below apex; cilia brown. Costal fold in male about 1/3 forewing length, brown. Hindwing and cilia light gray. Abdomen: Male genitalia ( Fig. 2 ) with tegumen vaulted, hairy on top; uncus drooping, represented by a pair of short haired processes, about 1/3 as long as socii; socii long, horn-shaped, located laterad of uncus. Valva deeply depressed ventrally, produced into an arc; neck relatively long; basal opening ovoid; sacculus ventrally with long hairs in a row, sacculus angle strongly protrudent, produced into a digitate process; cucullus ovoid, about 1.5 times as long as wide, hairy, with short marginal spines ventrally. Juxta subtriangular; caulis very short; anellus scarf-like, surrounding base of phallus; phallus straight tubular; cornuti deciduous (lost).

Host plant. Unknown.

Distribution. China (Hubei).

Etymology. This species name is derived from the Latin ovatus (= oval), indicating the shape of cucullus.
