Description
Adult ( Figure 1 View Figures 1–6 ): Forewing length 6.5–7.0 mm. Vertex and frons brown. Antenna dark brown. Labial palpus pale yellow; second segment with long scales; third segment shorter than second, slightly drooping. Thorax dark brown. Tegula pale yellow. Forewing with upperside ground color dark brown to grayish-white; basal patch dark brown, semiovoid, extending from base to 2/3 length of dorsum; median fascia and tornus grayish-white; subapical patch yellowish-brown, inverted triangular; costa with nine pairs of strigulae from base to apex, each strigula with a gray-silvery stria extending obliquely; strigulae one to four distributed between base of the wing and the point where Sc meets costa, separated from each other by dark brown spots; pairs of strigulae one and two occupying interfascial position, between basal and sub-basal fascia, situated before 1/10 forewing length, striae rarely extending beyond Sc; pairs of strigulae three and four occupying interfascial position between sub-basal and median fascia, with striae extending backward to 1/3 and 1/4 length of costa, respectively; each pair of strigulae (3–4) may be divided into four marks; strigulae five and six approximate at distal margin of median fascia, appearing as a single paired strigula; striae from these pairs usually confluent to termen; the distal three pairs distributed between pairs of veins R 1 –R 2, R 2 –R 3 and R 3 –R 4, respectively, bordered by reddish-brown and dark brown, separated from each other by dark brown spots; striae arising from them often becoming confluent to termen, extending to the point where R 5 meets termen; cilia with basal half grayish-white, distal half grayish-brown. Hindwing with upperside ground and cilia grayish-brown. Legs grayish-yellow, tarsi with dark brown scales. Abdomen grayish-brown.
Male genitalia ( Figure 26 View Figures 26–31 ). Uncus robust, entirely bifurcate. Socius ovoid, setose. Valva robust, broadest at 3/5; costa curved slightly at middle, ventral margin with two square projections, one subbasal, one near middle; ventromedial projection larger; neck robust, 5/6 width of cucullus; distal portion of valva extremely slender beyond ventromedial projection, nearly parallel-sided, about 1/3 length of valva. Aedeagus thick, cornuti consisting of a bundle of small spines, somewhat pectinately shaped.
Female genitalia ( Figure 49 View Figures 49–54 ). Papilla analis slender. Apophysis anterioris shorter than apophysis posterioris, both short. Sterigma obtuse isoceles triangle. Antrum short, well sclerotized. Ductus bursae short, one-half length of corpus bursae. Ductus seminalis originating posterior to corpus bursae. Corpus bursae ovoid, with a pair of differently sized blade-shaped signa.
Distribution
China (Gansu, Guizhou, Shaanxi) .
Diagnosis
This new species is similar to A. partitana in the male genitalia, but differs from it in the following aspects: in the new species, the basal patch is semiovoid, extending from the base to 2/3 the length of the dorsum on the forewing; the ventral margin of the valva has two square projections, and the neck is robust, twice the width of the aedeagus in the male genitalia. In A. partitana , the basal patch is obliquely semicircular, extending from the middle of the costa to 1/3 the length of the dorsum; the ventral margin of the valva has two triangular projections, and the neck is slender, 1.5 the width of the aedeagus.
Etymology
The specific name is derived from the Latin prefix ventr-, meaning ventral, and verticalis meaning square, referring to the ventral margin with two square projections.
