Lateral corner of clypeus: projecting into acute angle. Length of mediofacial striae: not extending above midpoint of compound eye. Anterodorsal node on interantennal process: absent. Central keel: absent. Length of OOL: less than 2 ocellar diameters. Macrosculpture of frons between median ocellus and inner orbit of eye: rugose. Patch of microsculpture posterior to lateral ocellus in female: absent. Patch of microsculpture between median and lateral ocelli: absent. Microsculpture on dorsal head: pustulate. Microsculpture of posterior gena: present. Shape of gena: not receding posterior to eye. Macrosculpture of posterior vertex: punctate rugose. Patch of microsculpture on temples: absent. Occipital carina above occipital foramen: appressed toward ocelli. Anterior margin of occipital carina above occipital foramen: comprised of cells. Ventral extent of occipital carina: extending to base of mandible. Setation of postgena: sparse.

Color of mesosoma: brown.

Shape of pronotal shoulder in dorsal view: narrow and striplike. Transverse pronotal carina: present in posterior half of pronotum. Dorsal half of pronotal cervical sulcus: present as smooth furrow. Ventral half of pronotal cervical sulcus: present as line of large cells. Sculpture of pronotal setal patch: coarsely striate.

Anterior notaulus: reaching mesoscutal suprahumeral sulcus as continuous furrow. Orientation of notauli: converging posteriorly. Shape of posterior notaulus: ovoid. Microsculpture on anterior half of medial mesoscutum: pustulate. Macrosculpture of anterior medial mesoscutum: absent. Pattern of punctation density on medial mesoscutum: uniform throughout. Scutoscutellar sulcus: comprised of round cells. Median carina on posterior mesoscutellum: absent. Posterior scutellar sulcus: comprised of shallow round cells.

Punctures on dorsal part of posterior mesepimeral area: absent. Mesopleural carina: absent. Postacetabular sulcus: crenulate. Striae ventrad of mesopleural carina: absent.

Setae on metascutellum: absent. Posterior margin of metascutellum: emarginate.

Setation of metapleural triangle: sparse. Paracoxal and metapleural sulci: separate. Sculpture of posterodorsal part of ventral metapleural area: smooth. Dorsal metapleural area: smooth defined area. Posterior margin of metapleuron below propodeal spiracle: with triangular point above metapleural sulcus.

Anterior projection of the propodeum: absent. Setation of metasomal depression: absent. Posterior projection of the propodeum: present as a point formed by plical and lateral propodeal carinae. 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. Color of costal cell in female: hyaline along stigmal vein, infuscate distally. Color of sub-radial area in female: infuscate. Color of cubito-medial area in female: infuscate. Color of anal margin in female: infuscate. RS+M in forewing: nebulous. Basal vein in hind wing: nebulous. Setation of hind wing: reduced anad of submarginal vein.

Color of metasoma: brown. Longitudinal median carina on horn of T1: absent. Armature on posterior surface of T1 horn: present. Form of armature on posterior surface of T1 horn: posteriorly projecting spine. Interstitial sculpture of T1: finely rugulose. Patch of dense fine setae on anterolateral T1: absent. Form of T2 sulcus: transverse furrow. Posterior margin of transverse sulcus on T2: straight. Carina along posterior margin of transverse sulcus on T2 in female: present. Sublateral tergal carina on T2: absent. Microsculpture on T2: present. Macrosculpture of T2 in female: longitudinally striate. Microsculpture on T3: present. Macrosculpture of medial T3 in female: weakly longitudinally strigose. Macrosculpture of lateral T3 in female: longitudinally strigose. Macrosculpture of female T5: absent. Microscupture on female T6: present throughout. Constriction of apical T6 in female: present. Macrosculpture of S1: rugose. Setation of S1: absent. 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.

Diagnosis.

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.

Etymology.

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