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.
