Material examined: (all from TAIWAN) HOLOTYPUS 1 ♂ Kaohsiung (on original label written Formosa (= Taiwan): Souktsu) 7.VI. 1912. leg. H. Sauter, det. H. H. Karny (Deutsches Entomologisches Institut, ZALF e.V. Müncheberg); Photomaterial from various sources and authors, all from Kaohsiung: Caishan NP: Flickr (by user ajstone 2548)— 7 * nymphs (late instars, sex indeterminable) 8.VI. 2014. (by user Bigfish Yeh) 1 ♀ Longqui: Tainan 7.IX. 2011.; Nature Campus: 1 ♂ + 1 ♀ 1.III. 2007., 1 ♂ 17.III. 2007., 1 * nymph (last instar, sex indeterminable) 8.VII. 2012. (by user m a [Sean Young]), 3 ♂♂ + 2 ♀ 22.XI. 2011. (by user yunol). Total material examined: 8 nymphs + 6 ♂♂ + 4 ♀♀ (18 specimens), all photo material was determined by J. Skejo.

* late nymph instars are very similar in morphology to adult specimens, the only difference being indeterminable sex because of not developed sex characters (ovipositor, male subgental plate) and lack of genicular and antigenicular teeth on hind knee

Distribution and habitat. The species was hitherto known from a single male specimen, holotype. We examined 15 additional specimens, 14 from the same area—from Kaohsiung county, Caishan (= Shoushan, Monkey Mountain) National Nature Park in SW Taiwan and a single female from Longqui— 70 km N of Kaohsiung. It seems that the species is endemic to the very small area or it has been overlooked in the past. Shoushan NP is surrounded by city areas, and thus the species' habitat could be fragmented. The area is characterized by low elevation (with highest hills at about 360 m a.s.l.) and a wet tropic climate. According to the photos examined, the species feed on mosses and algae. Nymphs tend to stay on brown vegetation and leaf-litter similar in color to their bodies. Adults tend to stay on rocky patches covered by algae and mosses, also similar to their body color. The distribution of the species needs to be studied more in detail to reveal if it is present on other similar Taiwanese habitats. The species distribution is shown on the map ( Fig. 1 View FIGURE 1 .) (blue area).
