Plical carina: present. Lateral propodeal area: raised above propodeal surface and indicated by lesser setation. Shape of lateral propodeal area: separate from prespiracular propodeal area. Sculpture of lateral propodeal area: areolate rugose.

Length of postmarginal vein: slightly longer than stigmalis (<1.5X). Rs in fore wing: nebulous. Cu vein in fore wing: nebulous. M vein in forewing: nebulous.

Distribution of longitudinal striae on S2: present throughout. Macrosculpture of S2: longitudinally striate. Form of S2 felt field: lateral row or patch of setigerous punctures. Marginal depression on S3: present. Marginal depressions on S4: present. Marginal depression on S5: present.


Paridris sulcata  is morphologically closest to Paridris bifurcata  . Females may be separated by the posteriorly directed spine on the horn of T1 and the single basiconic sensillum on A8.


The adjectival Latin epithet “sulcata” means “furrowed” and refers to the clearly defined and separate metapleural and paracoxal sulci.
