Parischnogaster jacobsoni
species of wasp
Parischnogaster jacobsoni is a species of social wasp within Parischnogaster, the largest and least known genus of Stenogastrinae. It is distinguished mainly by its tendency to construct ant guards on its nests. Natural selection has led this wasp to have a thick substance emitted from its abdominal glands that allows it to protect its nest from invasions. Parischnogaster as a genus has been relatively unstudied; P. jacobsoni is one of the few investigated species because it has sufficient durability to live near human populations and it has demonstrated unusual resilience to pollution. While P. jacobsoni is a more complex organism than other wasps in Parischnogaster, the genus overall is relatively primitive with respect to social wasps as a whole.
Taxonomy and phylogeny
The French entomologist Robert du Buysson described Parischnogaster jacobsoni in 1913. The species has no common name. Most common in Malaysia, stenogastrine wasps like P. jacobsoni wasps are generally found in South-East Asian rainforests. P. jacobsoni falls within the genus Parischnogaster, which is one subset of the hover wasps, or Stenogastrinae. Its relatively primitive traits are key to describing the evolution of social behavior in wasps.
Begin with the source’s own compact description: “Parischnogaster jacobsoni” is species of wasp. The dossier treats that line as a proposition to test through Parischnogaster, jacobsoni and species, not as a finished interpretation.
Why this record matters
The phrase “species of wasp” 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q14424525. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1913.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
