- Rhyacobates anderseni Tran & Yang, 2006 Rhyacobates anderseni Tran & Yang, 2006: 14 –16, Figs. 7 –16, 27 (type locality: Vu Quang, Ha Tinh Prov., Vietnam). Material examined. For holotype and paratypes, see Tran & Yang (2006). Size. Males, length 6.0– 6.1 (allotype 6.0), width 1.83–1.85 (allotype 1.83) (apterous), length 6.1–6.2, width 1.85–1.88 (macropterous); females, length 6.8 –7.0 (holotype 6.8), width 2.52–2.57 (holotype 2.52) (apterous). Remarks. The followings are diagnostic characteristics of R. anderseni: the mesonotum of the male has a slender yellow stripe on the posterior half; the mesonotum of the female has a broader yellow median marking on the posterior three-fifths; the abdomen of the male is relatively short; in lateral view, abdominal segment 8 of the male has a concave ventral surface; the male proctiger has round angular projections on each side (see Tran & Yang 2006: Fig. 12); the male paramere is falciform, slightly broad, long, and not conspicuously setose (see Tran & Yang 2006: Figs. 13, 14); the metanotum of the female has a pointed median process on the posterior margin (see Tran & Yang 2006: Fig. 7); the abdomen of the female is short (length about 0.2 times body length), sternum 7 is long, almost enclosing the genital segments with its connexival margin raised slightly upwards, with a pair of long posterior projections pointing outwards and downwards (see Tran & Yang 2006: Figs. 8, 9), and its posterior margin is almost straight, bearing two short lateral processes (see Tran & Yang 2006: Fig. 10). For detailed comparisons of Rhyacobates anderseni with its congeners and other ptilomerine genera (Andersenius and Pleciobates), refer to Tran & Yang (2006: 16). Habitats. See Tran & Yang (2006: 16).
