( Figs. 22–31 View FIGURES 22–31 )
Type materials. Holotype, male ( CAU): Gushan, Fuzhou , Fujian Province, 21 Nov. 1974, coll. Chi-kun Yang ; Paratypes, 1 female ( CAU), Gushan, Fuzhou , Fujian Province, 20 Oct. 1974 ; 1 female ( CAU), Aotou, Jianyang , Fujian Province, 28 Oct. 1974, coll. Chi-kun Yang.
Length. Male 3.2 mm, female 3.0– 3.2 mm.
Ground colour of body red to carmine. Vertex with a small yellowish patch bordering eye. Face red to reddish orange, anteocular areas with a yellowish patch. Apical 1/3 of forewing semitransparent, veins reddish, veins of hind wing red to reddish orange. Abdomen red dorsally, sternites laterally with large yellowish patch and a more posterior small yellowish patch on each of segments 3–8. Legs yellowish with fore femur and tibia and most part of third tibia, reddish-orange. Female valvula red.
Abdodminal apodemes reaching end of segment 4. Male pygofer strongly narrowed in apical half, with 10–11 rigid setae on pygofer lobe with more distal setae longer, lobe-like structure of dorsal margin with 2 spine-like setae; ventral pygofer appendage arising from near middle of ventral margin, sinuate and broad medially. Subgenital plate broadest at base, gradually tapering to apex, with 3 macrosetae in basal group, about 15 marginal spine-like setae laterally, and 11–13 uniseriate macrosetae, starting caudad of, and similar in length to, basal group setae. Paramere broad at base, sinuate, apex bearing more than 10 denticles preceded by about 4 setae. Aedeagal shaft with pair of leaf-like process subapically and pair of short apical processes, more or less straight, dentate basally at outer margins. Anal tube process broad at base, tapering and curved apically.
Etymology. The name is derived from the Latin word lamellatus (leaf-like), which refers to the shape of the subapical aedeagal processes.
Female. Unknown.
Discussion. Dayus lamellatus n. sp. is similar to D. takagii but it differs from the latter in having the subapical processes of the shaft leaf-like and more laterally curved, and the apical processes shorter and straighter in dorsal view with small teeth at the outer margins basally.
