Baliosus pectoralis
species of insect
Baliosus pectoralis is a species of beetle of the family Chrysomelidae. It is found in Brazil (São Paulo).
Description
The head is moderately produced between the eyes and the vertex is smooth with a longitudinal groove. The antennae are equal in length to the head and thorax. The thorax is nearly twice as broad at the base as long, with the sides narrowly margined, crenulate, nearly straight at the base, narrowed and rounded in front. The upper surface is transversely impressed on the hinder disk, transversely excavated on the basal lobe, the latter broadly truncate, stained on either side with a piceous spot. The middle of the disk in front is nearly impunctate, finely strigose, the sides coarsely and deeply rugose-punctate. The scutellum is large and triangular. The elytra are much broader at their base than the thorax. The humeral callus is thickened, not raised above the surface of the elytra, but produced horizontally, it is subacute, not extending beyond the lateral border.
This brief starts where responsible research should: with the source description of “Baliosus pectoralis” 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.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q1885610. None of the 0 selected statements returned an explicit reference.
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
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
