Tropistethus antennatus Scott, 1874, Ann.Mag.Nat.His. 14(4): 429;

Lamproceps antennatus Scudder, 1962: 768; Slater, 1964: 823; Slater & O’Donnell, 1995: 97; Péricart, 2001: 157. Diniella yinae Zheng & Liu, 1992: 257 . New synonymy.

Complementary description. Measurements. Length head 0.38, width 0.63, interocular space 0.41; Length antennal segments I 0.31(0.28–0.36), II 0.40(0.38–0.42), III 0.33(0.30–0.35), IV 0.44(0.39–0.49); Length pronotum 0.63, width anterior pronotal margin 0.57(0.56–0.59), width posterior pronotal margin 1.03(1.0–1.06); Length scutellum 0.60(0.56–0.65), width 0.58(0.51–0.63); Midline distance apex clavus–apex corium 1.02(0.94–1.09), midline distance apex corium–apex membrane 0.60(0.56–0.65); Total body length male 2.5–3.0, female 2.5–3.4. Five specimens were measured of this species

Male genitalia: Parameres, pygophore, and sperm reservoir as Figs. 3, 6, 7, 8 shown.

Material examined. CHINA, Hainan: 2 males, Mt. Jianfeng, 22.IV.1985, leg. Zheng Leyi, light trap; 1 male, 1 female, as the former, 21.IV.1985; 1 female, as the former, 18.IV.1985; 1 male, as the former, 24.IV.1985; 1 female, Mt. Jianfeng, 15.IV.1980, leg. Zheng Leyi, light trap. Zhejiang: 1 male (Paratype of Diniella yinae Zheng & Liu), Mt. Tianmu, 5.IX.1989.

Distribution. China (Hainan, Zhejiang); Japan.

Biology. Most specimens were collected by light trap, indicating nocturnal activity of this species.

Notes. Diniella yinae was originally described by Zheng & Liu in 1992 based on two males and one female collected in province Zhejiang. We examined a paratype (male), as well as additional specimens from province Hainan, and found it to had typical diagnostic characters of Lamproceps rather than Diniella, such as: body clothed with semierect hairs; antennae with the fourth segment whitish yellow; pronotum flat, anterior margin straight and lacking a collar–like area; corium with lateral margins parallel. Furthermore, like Lamproceps indicus in O’Donnell, 1991, Diniella yinae has “V” shaped holding sclerites in sperm reservoir, and holding sclerites are absent in Diniella . Therefore, we determined that this species belongs to the genus Lamproceps Reuter, and it completely fits the description of Lamproceps antennatus (Scott 1874); for this reason we treat Diniella yinae Zheng & Liu as a new synonym of Lamproceps antennatus (Scott) .
