Genus Ariptyelus Matsumura, 1940 Aphrophora Germar, 1821 (in part). Matsumura, 1907, Annot. Zool. Jap. 6: 83–116. Ariptyelus Matsumura, 1940, J. Fac. Agric. Hokkaido Imp. Univ. 45 (2): 50. Toroptyelus Matsumura, 1942, Ins. Matsum. 16: 90–91 (Type species: Toroptyelus arisanus Matsumura, 1942) [syn- onymised by Liang, 1998: 243]. Type species: Aphrophora auropilosus Matsumura, 1907 Coloration: Body light brown to dark brown. Eyes yellowish brown to brown. Ocelli red. Genae and base of mouth parts brown to dark brown. Tegmen (Figs. 1 A, 1 C, 5 C) with discontinuous dots on basal half of costal margin. Wing hyaline, veins brown; apical area, first apicall cell, and the second apical cell with brown pubescence. Fore and middle legs brown, with ring bands dark brown. Hind leg brown to dark brown. Structure: Body spindlelike (Figs. 2 A, 2 C, 5 A), medium sized (including tegmen about 5.6–7.3 mm long), head width: body width: body length= 1: 1.3–1.4: 2.8–2.9. Head triangular, with distinct median carina running from vertex to mesoscutellum. Head slightly wider than pronotum at level of anterior margin, about 1–1.1: 1. Frons in frontal view prominent, but longitudinally flattened medially, with indistinct median carina basally, with 11 transverse ridges at each side. Antenna, with scape short cylindrical; three basiconic sensilla near base of flagellum, plate- like, 2 elongate, the ovate one set between elongate ones. Rostrum reaching apex of hind coxae. Tegmen (Figs. 1 A, 1 C, 5 C) subquadrate, AM: PM: LT = 1: 1.5–2.1: 3.1–4; venation typical; the joint of M and Cu 1 basad of joint of R 1 and Rs; 1 A parallel with Cu 2. Wings (Figs. 1 B, 1 D, 5 D) with 4 apical cells, apical cells with first one longer than third by ratio of 1.4–1.7: 1, second apical cell closed by r-m cross vein, third apical cell closed by m-cu cross vein; apical area with brown pubescence; wing coupling apparatus with 3–4 hooks (Figs. 1 B, 1 D, 5 F) on basal part of costal margin. Meracanthus of midleg triangular and lamellate, with median carina. Hind tibia with 2 lateral spines, basal one approximately 0.4–0.6 times closer to apex of femur than distal one is to apex of tibia; apical spines arranged in 2 rows, upper row with 7– 9 spines, lower one with 8–10 spines. Male Genitalia: Pygofer subquadrate in lateral view (Figs. 3 A, 4 A, 6 A), about 1.2–1.3 times wider than long; basal margin of pygofer (bmp) curved inward to various degrees; dorsal process of pygofer (= pygofer disk) cone like in lateral view, ventral process of pygofer (= genital plate) in lateral view, shorter than ventral length of pygofer about 1: 1.7–3.7; ventral process (LWVP) at widest part narrower than basal width of pygofer (LBWP) about 1: 4.9–5.5. Abdominal segment X cylindrical. Abdominal tergite of segment XI (XIt) rooflike, sternite XI somewhat ovate. Aedeagus (Figs. 3 E, 4 E, 6 E) membranous, elongate or trapezoidal in lateral view. Phallobase and connective not separated. Genital styles triangular in lateral view (Figs. 3 C, 3 D, 4 C, 4 D, 6 C, 6 D); width of apical part about 0.5–1.2 times length of genital style (WAGS: LAGS = 0.5–1.2: 1) on outer side, margin with complete to incomplete prominence on inner side. Remarks: Ariptyelus is similar to the genus Peuceptyelus , but the differences are summarized in Table 1. The morphological definition of Peuceptyelus is based on the description of Ossiannilsson (1981). Species of Ariptyelus may be distinguished using the following key. : Published as part of Shih, Hsien-Tzung & Yang, Jeng-Tze, 2007, Revision of the genus Ariptyelus Matsumura (Hemiptera: Cercopoidea: Aphrophoridae), pp. 57-68 in Zootaxa 1592 on pages 58-59, DOI: 10.5281/zenodo.178585 : {"references": ["Matsumura, S.
