. In full-face view, head subrectangular, lateral margins mildly diverging posteriorly from the most constricted level (just posterad the clypeal lobes) to the compound eyes level; vertexal margin mildly concave and vertexal corners neither too weakly, nor too strongly marked. Clypeal lobe well-developed, its width much larger than torular diameter. Clypeal chaetae count around 34. Portion of dorsal surface of mandible, which is ventrally turned, with a filiform, erect seta on its middle. Teeth on masticatory margin of mandible as for the genus, but apical tooth relatively large. Spiny chaetae on ventral surface of mandible and stout labral chaetae as for the genus, the distribution of chaetae on labral disc is not visible. Labral distal margin not visible. Labio-maxillary complex including all palpomeres not visible. Posterior clypeal margin (epistomal sulcus) weakly marked. Frontal carinae well-impressed. Dorsal surface of the head with abundant piligerous marks, but no setae visible. This punctation is likely the marks of very fine head pubescence (difficult to confirm). Antennae without standing setae.

. In profile, dorsal mesosomal outline gently convex, meeting an oblique posterior propodeal margin at a marked angle. In dorsal view, mesosomal outline subrectangular, lateral margins flat to mildly convex, region corresponding to promesonotum slightly wider than that corresponding to propodeum. Propodeum in dorsal view with a flat to mild concave posterior margin. Propodeal spiracle slit-shaped, relatively small (

Protibia having a pair of simple spur-like next to the calcar; calcar velum poorly-developed, tip of calcar frayed; mesotibial spurs subequal, the posterior one with inconspicuous barbulation; metatibial smaller (anterior) spur simple, larger (posterior) spur pectinate.

In lateral view, anterior petiolar margin convex, apex only a brief curvature which leads to posterior descending margin which is also convex, especially on the lower portion. Petiole in anterior view subrectangular, the apical transverse margin almost straight. Although not forming a conspicuous dorsal surface, petiole is relatively thickened, not sharpened on the apex or lateral edges. Gaster large. A mild cinctus present on A4, indicated by a soft curvature at the edge of A3 tergite which articulates on A4 pretergite. Metasoma glabrous, except for A57, which bears several curved, long, simple setae on its edge. Sting tip exposed.

The specimen has little or no distortion or stretching, the cuticle is not damaged or desiccated. The matrix is very clear, but has a fracture that crosses the specimen from side to side, passing in the head posteriorly and upper mesosoma. The fracture causes a mirroring effect which does interfere significantly with the visualization of the ant, however, multiple facets and different illumination might reveal parts that are obscured by that artifact.

The name is in honour of the great paleontologist Vincent Perrichot. The name was created by adding the singular Latin genitive case suffix -i to the last name of a male person. The orthography of an eponym is unchangeable and not dependent on the generic name in which the epithet is used.
