Reticuluma bipennata Xu & Dai sp. nov.

( Figs. 1 A–D, 2A–F, 3O–P, 5D, H, L)

Measurement. Body length (including tegmen): male 3.6–3.8 mm.

Description. Pronotum, scutellum and forewings with reticulate color pattern ( Fig. 1A). Anterior margin of crown arcuate forward, vertex of crown sloped, longer than half of width to eyes, with three black patches arranged in arc. Face black, coronal suture about 3/5 length of vertex ( Figs. 1B, D). Ocelli yellow-gray, eyes black with gray stripes. Two yellow spots between eyes, equidistant between eye and coronal suture. Pronotum pale yellowish with dark brown patches on posterior margin. Pronotum approximately 2 times length of crown. Scutellum pale yellowish, with grayish brown patch close to apical area and each basal angle, suture distinct. Forewing subhyaline, with five apical cells ( Fig. 1A).

Male genitalia. Male pygofer quadrate in lateral view with short macrosetae near posterior margin ( Fig. 2A). Subgenital plate similar to triangular with several short setae near the lateral margin ( Fig. 2B). Connective Y-shaped, stem slightly shorter than arms ( Fig. 2C). Style slender, broad subapically, acute at apex ( Fig. 2D). Aedeagal shaft triangle-like in dorsal and ventral view ( Figs. 2E, 3O), arcuate in lateral view ( Figs. 2F, 3P). Aedeagus shaft with a pair of wing-shaped processes in lateral margin in dorsal view, the processes with several setae near inner margin centrally; gonopore apical ( Figs. 2E, 3O).

Type material. Holotype: ♂ ( GUGC), CHINA, Yunnan Prov., Mt. Gaoligong, Baihua Ridge , 22 May 2019, coll. Xu Tielong ; Paratypes: 1♂ ( GUGC), CHINA, Yunnan Prov., Mt. Gaoligong, Baihua Ridge , 05 August 2013, coll. Yang Weicheng ; 1♂ ( GUGC), CHINA, Yunnan Prov., Xinping County, Mt. Wenbi , 22 July 2018, coll. Wang Xianyi ; 1♂ ( GUGC), CHINA, Yunnan Prov., Mengla County, Menglun Town , 13 June 2019, coll. Xu Tielong.

Etymology. The new species name is an adjective that combines the Latin prefix “ bi- ” (two) with “ penna ” (feather), referring to the two wing-like processes of the aedeagus.

Remarks. The new species is similar to R. lageniformia , but can be distinguished from the later by the shape of the aedeagus with wing-like processes and the aedeagal shaft situated lower than the wing-like processes ( Figs. 2E, F, 3O, P), the basally broad connective ( Fig. 2C), and the style preapical lobe without setae near the inner margin ( Fig. 2D).
