Setation of postgena: sparse. Ventral extent of occipital carina: extending to base of mandible.
Color of mesosoma: mesoscutellum brown, otherwise golden orange. Dorsal half of pronotal cervical sulcus: present as smooth furrow. Ventral half of pronotal cervical sulcus: present as line of small to minute cells. Transverse pronotal carina: present in posterior half of pronotum. Shape of pronotal shoulder in dorsal view: narrow and striplike. Form of pronotal suprahumeral sulcus: areolate. Macrosculpture of anterior medial mesoscutum: absent. Density of punctation on anterior medial mesoscutum: dense along mesoscutal suprahumeral sulcus, otherwise sparse. Reticulate microfissures on anterior half of medial mesoscutum: absent. Pustulate microsculpture on anterior mesoscutum: absent. Density of punctation on posterior medial mesoscutum: sparse. Notaulus: percurrent, reaching suprahumeral sulcus as a smooth furrow. Orientation of notauli: converging posteriorly. Shape of notaulus at posterior apex: ovoid. Macrosculpture of mesoscutellum: punctate rugose along margins, smooth medially. Postacetabular sulcus: crenulate. Mesopleural carina: absent. Punctures on posterodorsal mesepimeral area: absent. Sculpture of mesopleuron anteroventral to femoral depression: moderately punctate. Sculpture of posterior mesepimeral area: rugulose. Form of metascutellum in male: transverse lamella, posterior margin convex. Paracoxal and metapleural sulci: separate. Posterior margin of metapleuron below propodeal spiracle: with blunt angle near intersection with metapleural sulcus. Setation between metapleural triangle and metapleural sulcus: absent. Sculpture between metapleural triangle and metapleural sulcus: smooth. Sculpture of metapleural triangle: punctate rugose. Setation of metapleural triangle: moderately dense. Anterior propodeal projection: absent. Setation of metasomal depression: absent. Lateral propodeal area: raised above plical area and indicated by sparser setation. Plical carina: present. Shape of lateral propodeal area: separated from prespiracular propodeal area. Sculpture of lateral propodeal area: weakly to moderately rugose.

Wing development: macropterous. Basal vein in hind wing: spectral. Setation of hind wing: reduced anad of submarginal vein. Length of postmarginalis: punctiform. RS+M in fore wing: spectral.
Diagnosis
The form of the lateral propodeal area in Paridris invicta is unique among the New World species of Paridris. In members of the Paridris pallipes species group the plica is absent and thus there is no distinction between the plical area and lateral propodeal area. In other New World species the plica is well developed and the lateral propodeal area is contiguous with the prespiracular propodeal area. In Paridris invicta, the plica is distinct, and separates the plical area from the lateral propodeal area, and the lateral propodeal area is not contiguous with the prespiracular propodeal area; by this character alone it may be separated. In addition, the enlarged femora and dense, elongate setation of the head and mesosoma serve well to identify this species.
Etymology
The Latin adjectival epithet “invicta” means “unconquered” or “strong”. It is given to this species for the large size of its legs and its powerful appearance.
