Orestes guangxiensis
species of stick insect
Orestes guangxiensis is a representative of the genus Orestes.
Characteristics
So far only females are known of Orestes guangxiensis. In 2005 Paul D. Brock and Masaya Okada mistakenly described males of this species from Japanese island Miyako-jima. George Ho Wai-Chun assigned this to Pylaemenes japonicus described by him in 2016 (today's name Orestes japonicus).
The females are 40 to 50 millimetres (1.6 to 2.0 in) long and stocky in shape. Their basic color is usually a light beige or brown, which is complemented by almost white, brown and black patterns. The body surface is covered with small, mostly black tubercles. In the middle of the otherwise flat upper side of the thorax a weak carina can be seen. The comparatively short mesonotum is 2.5 times as long as the pronotum and thus significantly shorter than in longer species such as Orestes mouhotii or Orestes shirakii. On the forehead that becomes narrower towards the top, the four elevations form two edges that converge towards the tip of the forehead, which when viewed from the front form a triangle.
Begin with the source’s own compact description: “Orestes guangxiensis” is species of stick insect. The dossier treats that line as a proposition to test through Orestes, guangxiensis and species, not as a finished interpretation.
Why this record matters
The phrase “species of stick insect” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 30, 2026. The linked authority identifier is Q108044613. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005 and 2016.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
