Acanthispa nigripennis
species of beetle
Acanthispa nigripennis is a species of beetle of the family Chrysomelidae. It is found in French Guiana.
Description
Adults are elongate and shining red, while the head, a short vitta on either side of the thorax, its extreme apical margin, together with the elytra are shining black. The head is slightly excavated on the forehead and the vertex is shining and impunctate. The thorax is nearly one-third broader at the base than long, the sides rounded, narrowed in front, above subcylindrical, deeply excavated transversely near the base. The surface is impressed here and there with deep distinct punctures, a black stripe on either side closely punctured, subrugose. The scutellum is impunctate, shining red. The elytra is much broader than the thorax, sides parallel, their outer edge armed with fine, distinct serratures, posterior angles produced directly backwards into a stout acute spine. Each elytron has three elevated costae, the outer one less raised than the others, interstices impressed with a double row of deep regular punctures, the third interstice from the suture irregularly punctured along the posterior two-thirds of its course. Beneath shining rufous, the apex of the abdomen piceous.

Why this record matters
“Acanthispa nigripennis” is worth following because a concise public description often conceals a longer documentary argument. Here, Acanthispa, nigripennis and species provides the most credible route into that argument.
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 Q2291692. 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.
