Description.

Female body length: 1.15 mm (n=1).

Color of head: reddish brown. Distal margin of clypeus: smooth. Shape of distal margin of clypeus in anterior view: convex. Width of clypeus: greater than width across toruli. Lateral corner of clypeus: projecting into acute angle. Length of mediofacial striae: not extending above midpoint of compound eye. Central keel: absent. Macrosculpture of frons between median ocellus and inner orbit of eye: absent. Microsculpture on dorsal head: pustulate. Shape of gena: weakly to moderately receding posterior to eye. Macrosculpture of posterior vertex: absent. Occipital carina above occipital foramen: simple. Anterior margin of occipital carina above occipital foramen: comprised of cells. Ventral extent of occipital carina: extending to base of mandible.

Color of mesosoma: pale brown.

Shape of pronotal shoulder in dorsal view: narrow and striplike. Transverse pronotal carina: present in posterior half of pronotum.

Anterior notaulus: absent. Shape of posterior notaulus: ovoid. Microsculpture on anterior half of medial mesoscutum: pustulate. Macrosculpture of anterior medial mesoscutum: irregularly rugulose. Pattern of punctation density on medial mesoscutum: increasing anteriorly. Scutoscutellar sulcus: comprised of round cells. Median carina on posterior mesoscutellum: absent. Posterior scutellar sulcus: comprised of deep cells.

Punctures on dorsal part of posterior mesepimeral area: absent. 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. Dorsal metapleural area: smooth defined area.

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: con tinuous with prespiracular propodeal area. Sculpture of lateral propodeal area: weakly to moderately rugose.

Length of postmarginal vein: equal to stigmalis. Rs in fore wing: spectral. Cu vein in fore wing: spectral. M vein in forewing: spectral. Color of costal cell in female: hyaline. Color of sub-radial area in female: hyaline. Color of cubito-medial area in female: hyaline. Color of anal margin in female: hyaline. RS+M in forewing: nebulous. Basal vein in hind wing: spectral. Setation of hind wing: uniform throughout.

Color of metasoma: reddish brown. Longitudinal median carina on horn of T1: absent. Armature on posterior surface of T1 horn: absent. Patch of dense fine setae on anterolateral T1: absent. Constriction of apical T6 in female: absent.

Diagnosis.

Paridris densiclava shares the smoothly convex shape of T6 with Paridris nigriclava , and differs by having a postmarginal vein as long as the stigmal vein. This venation is shared by Paridris nitidiceps , also from the Seychelles and known from a single male. We separate these species on the basis of the complete notaulus and punctate posterior mesepimeral area in Paridris nitidiceps . The notaulus of Paridris densiclava is present as a single fovea on the posterior margin of the mesoscutum and the posterior mesepimeral area is entirely smooth.
