Scaphoideus kumamotonis Matsumura, 1914

( Figs. 2 B, G, L, 3E, 4C, 4G, 10A–G, 14G–I, 15G–I, 16G–I)

Scaphoideus kumamotonis Matsumura, 1914: 224 ; Okada, 1977: 195; Li & Wang, 1991: 196; Cai & Shen, 1999: 243; Cai et al., 2001: 203; Cai & Shen, 2002: 276; Li & Chen, 2002: 198; Xing & Li, 2010: 137; Chen et al., 2012: 89; Kamitani & Hayashi, 2013: 518 .

Coloration and structure ( Figs. 2 B, G, L, 3E) as in S. coniceus and as described by Matsumura (1914) and Kamitani & Hayashi (2013), but forewings with three reflexed cross veins between outer anteapical cell and costal margin, basal reflexed vein basad of outer anteapical cell ( Figs. 2 B, G).

Male genitalia. Pygofer elongate, narrowly rounded posteriorly, with two tufts of long macrosetae subapically in addition to scattered short macrosetae( Figs. 10 A, B). Subgenital plate triangular and broad basally, apical margin rounded, with 2–3 macrosetae at base and fine hair along lateral margin ( Fig. 10 C). Style small, with well developed preapical lobe, apical process moderately long, curved laterally, abruptly tapered distally to acute apex, ventrolateral surface serrate, a few setae adjacent to lateral lobe on dorsal and ventral surface ( Fig. 10 C, D). Connective Y-shaped, stem longer than arms; connective processes converge at the base then parallel, each paraphysis slight widen from base to apical 1/2, and then tapered to acute apex ( Fig. 10 C, E). Aedeagus with well developed dorsal apodeme, shaft straight and compressed laterally, apex curved posteriorly, with a pair of long lateral processes at apex directed laterobasally, and two parallel ridges along dorsal margin near apex ( Fig. 10 F, G).

Female genitalia. Caudal margin of seventh sternum medially produced with a notch in the middle, the edge of the notch blackish ( Fig. 4 C, G). Other characteristics ( Figs. 14 G–I, 15G–I, 16G–I) as in S. albovittatus Matsumura.

Measurements. Male 4.2–4.8mm long, 0.9–1mm wide across eyes. Female 4.4–5.1mm, 1.0- 1.1mm wide across eyes.

Distribution. China (Anhui, Guangxi, Guizhou, Henan, Hubei, Hunan, Jiangxi, Shaanxi, Sichuan, Xizang, Yunnan, Zhejiang); Japan.

Remarks. This species was described by Matsumura (1914) from Japan. Ishihara (1961), Okada (1977) and Kamitani & Hayashi (2013) redescribed it and gave the illustrations, respectively. From the illustrations of Kamitani and Hayashi (2013), the aedeagal shaft of S. kumamotonis has a pair of processes on the subapical dorsal surface shorter than the apical pair. But, based on the figures of Okada (1977), Chen et al. (2012) and in our examination of specimens, these dorsal "processes" are parallel ridges along the dorsal margin near the apex.
