Agnesiella (Draberiella) geminicruciata Wang & Huang 2025, sp. nov.

Agnesiella (Draberiella) geminicruciata Wang & Huang sp. nov. Figs 13–16, 20, 21–26 Description. Body largely yellowish (Figs 13, 14). Face mostly dark brown, frontoclypeal area with dark brown transverse stripes, lorum ivory (Fig. 16). Vertex yellowish-brown medially, remaining parts yellowish, with a pair of blackish-brown patches. Pronotum with some blackish-brown patches, median area light brown; triangles dark brown, scutellum yellowish (Fig. 15). Forewing with one brown patch each at middle and apical part in basal 2 / 3, apical 1 / 3 smoky brown, brochosome area pale yellow with a blackish-brown patch at each end (Fig. 20). Abdominal apodemes extending nearly to middle of 6 th abdominal sternite (Fig. 21). Male genitalia. Male pygofer with two longitudinal bands of long fine setae medially near ventral margin, and posterior band more elongate; posterior margin with a short horn-like pygofer process on the lower part, a medial cluster of small rigid setae (Fig. 22). Subgenital plate with expanded distal part, bearing some long fine setae and small rigid setae; a distinct protrusion subapically with peg-like setae apically (Figs 22–24). Paramere slender, with apex curving distinctly outward and a small subapical tooth on ventral margin (Figs 22, 23). Connective with central lobe (Fig. 23). Aedeagal shaft relatively straight, with lamellate lateral expansions (Figs 25, 26); ventral margin with two intersecting processes at the middle: right process longer, extending to shaft apex, and left process curves leftward to the shaft in posterior view (Fig. 26). Specimens examined. Holotype: China • ♂; Yunnan Prov., Puer, Ailaoshan National Nature Reserve; 101°15'55.50"E, 24°16'32.83"N; 2200 m; 6 Jun. 2022; J. J. Wang; NWAFU. Paratypes: 2 ♂♂, 1 ♀, same data as for holotype • 5 ♂♂, 3 ♀♀; Yunnan Prov., Luchun, Huanglianshan National Nature Reserve; 102°32'33.71"E, 23°2'2.24"N; 2050 m; 10 Jun. 2023; L. Lu; NWAFU. Measurement. Males, 3.15–3.28 mm (including wing). Etymology. This specific epithet is derived from the Latin words “ gemini ” and “ crux ”, referring to the two intersecting processes on the ventral margin of the aedeagal shaft (Figs 25, 26). Remarks. This new species closely resembles A. xantha Yan & Yang in the male genitalia, but can be distinguished by two intersecting ventral processes on the aedeagal shaft, each originating independently from the shaft (Figs 25, 26).
