description: Sogana hopponis Matsumura
(Figs. 2, 3, 10–12, 20, 25, 32–35, 46, 47)
Sogana hopponis Matsumura, 1914:268, figs. 3a-e; Melichar, 1914:114, 116; Esaki, 1937:24, pl. 3, fig. 2; Metcalf, 1954:131; Tsaur, 1990:245, fig. 2; Liang & Suwa, 1998:163; Wilson & Malenovsky, 2007: 148. Lectotype ♂, designated by Liang & Suwa, 1998:163, Taiwan (HU) [examined].
Redescription. Length (from apex of vertex to tip of fore wings): ď 9.0–10.0 mm, Ψ 9.3–11.0 mm.
General color tawny brown. Vertex (Figs. 2, 3, 10) with four black spots at apex; lateral areas between sublateral carinae and lateral carinae suffused with blackish; median carina blackish with apical half obliterate; sublateral and lateral carinae pale orange, lateral margins orange to reddish; central disc with a blackish stripe along the inner side of each sublateral carina. Carinae on pronotum and mesonotum yellowish brown. Frons (Fig. 11) with 6 pairs of reddish transverse bands, carinae on frons and clypeus brown. Gena (Fig. 12) with one black patch. Ocelli (Fig. 12) surrounded with red. Fore wings with brownish nebula apically. Legs yellowish brown; fore femora, bases of tibiae, and long stripes on hind femora blackish; basal part of hind femora with one reddish stripe.
Vertex with anterior margin projected at an obtuse angle in dorsal view, lateral areas distinctly depressed; median carina protruding forward from base to apical fourth. Fore wings with 16–18 apical cells and 7 subapical cells, two middle anteapical cells not equally long. Spines of hind legs: hind tibia laterally 3, distally 6–7, basitarsus distally 8–9.
Proportions. Vertex with ratio of median length to the widest breadth 1.03:1, frons with ratio of median length to the widest breadth 1.54:1, pronotum with ratio of width to median length 4.82:1, pronotum and mesonotum together medially about 1.53 times as long as median length of vertex, fore wings with ratio of length to maximum breadth 3.54:1.
Male genitalia (Figs. 25, 32–35, 46, 47) with pygofer relatively high and broad, posterior margin relatively broadly expanded caudad in lateral view (Fig. 25). Anal tube (Figs. 25, 32) relatively narrow and long. Gonostylus (Figs. 25, 34, 35) 3.93 times as long as broad in lateral view. Aedeagus (Figs. 33, 46, 47) with three processes: the longest one arising from left side at apical fifth and approximately reaching to base of aedeagus, having 3–4 tiny, sub-middle, ventrally and inwardly directed teeth; the shortest one arising from right side at apical third, directed dorsally, with 2–3 fine spines; the third process stout, apically lanceolate, posteriorly directed, arising below the shortest process on ventral side; endosomal process twisted, relatively short and thick; phallotrema exposed apically (Figs. 46, 47); periandrium (Figs. 38, 55, 56) with a relatively long and broad, tongue-shaped process protruding backward from ventral apex.
Material examined. Lectotype ď, designated by Liang & Suwa (1998: 163), Formosa Matsumura [underside] Shoka 7/20-06 (HU). Taiwan: 1Ψ (paralectotype), 8/VIII Hoppo, [Matsumura’s handwriting] Sogana hopponis n. sp.; [red label] Type Matsumura; 2ΨΨ (paralectotypes), Formosa Matsumura [underside] 20/VII 1906 Shoka (all in HU).

Distribution. China (Taiwan, Hainan Island), Japan (Amami–Oshima, Ryukyu Islands, Iriomote Loochoo Islands).
Remarks. This species is externally similar to S. longiceps Fennah, 1978 but can be distinguished from the latter by the vertex with median carina surpassing basal half (Fig. 7), fore wings (Fig. 20) with the two middle anteapical cells not equally long, and the aedeagus (Figs. 33, 46, 47) with the endosoma not dilated apically and the endosomal process twisted, relatively short and thick.
