Saigona taiwanella Matsumura, 1941

Saigona taiwanella Matsumura, 1941: 163 ; Yang & Yeh, 1994: 115. Holotype Ψ, China ( Taiwan: Kayahara, Taichu) (missing from HU).

Diagnosis

Length Ψ 16.0 mm.

Similar to S. sinicola Matsumura , but differs from the latter as follows: Ψ, Body darker; the granulous pale pigments of the cephalic process on the upper surface obsolete; the central longitudinal yellowish stripe in the scutellum much narrowed towards the apex. The apical cells on the tegmina nearly in the same length, whereas in sinicola Matsumura the middle two are much longer, having no cross-veins; stigma with 3 veins, the outer one branching from the middle. Mesosternum largely fuscous. Abdomen dorsally largely fuscous. Legs with all the tibial apices fuscous; the anterior femur near the femoral spine near the apex much lower. The genital organ resembles that of S. sinicola Matsumura , but is darker. (After Matsumura, 1941)

Male. Unknown.

Remarks

Matsumura (1941) described S. taiwanella based on one single female species from Taiwan, China. The species was neglected by Metcalf (1946) and was not included in his world catalogue of Dictyopharidae . Yang & Yeh (1994) listed this species. Liang & Suwa (1998) reported that they failed to find the holotype of this species in Matsumura’s collection housed in the Hokkaido University, Sapporo, Japan. Specimens, especially the males, of this species are needed to determine its status.

Distribution
