Brasidas cavernosus
species of insect
Brasidas cavernosus is a representative of the stick insects native to the Philippine island Luzon. It is considered one of the largest species in the subfamily Obriminae.
Taxonomy
The species was described in 1877 by Carl Stål under the basionym Obrimus cavernosus in the genus Obrimus, which had also been set up by Stål two years earlier. He calls them closely related to Obrimus bufo and distinguishes them from the latter by the slightly different spines on the body and legs. The main difference is the lateral pits in the metasternum, which also give the species its name ("cavernousus" Latin for cave-like). In 1933, Sjöstedt mentioned the female presumably used for the first description as a holotype. It is in the Swedish Museum of Natural History in Stockholm.
Joseph Redtenbacher examined three animals in 1906, more precisely one male and two females, which he assigned to this species. The male from the Natural History Museum, Berlin was collected on Luzon, the females from the National Museum of Natural History, France in Paris were collected on Mindanao. He mentions at the end of the description that it is not certain whether both sexes belong to the same species.
This brief starts where responsible research should: with the source description of “Brasidas cavernosus” as species of insect. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of insect. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 3, 2026. The linked authority identifier is Q10490603. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1877, 1933 and 1906.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
