( 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 ). FIGURE 1. A–D. Reticuluma bipennata sp. nov. A, habitus, dorsal view; B, head and pronotum, dorsal view; C, habitus, lateral view; D, face. 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 ).
