Description.

Female body length: 2.53-3.26 mm (n=20). Color of head: black throughout. Ventral clypeal margin: serrate. Sculpture of frons medially: smooth. Sculpture of frons immediately ventral of median ocellus: dorsoventrally strigose throughout. Microsculpture of frons: absent. Sculpture of posterior vertex: punctate rugulose. Sculpture of gena: irregularly rugulose. Basiconic sensillum on A7: absent.

Wings: macropterous, apex of forewing extending beyond posterior margin of T3. Length of R1: equal to r-rs; less than r-rs. Notaulus: percurrent. Color of mesosoma: orange to dark red anteriorly, brown posteriorly, mesoscutellum black. Sculpture of mesoscutum medially: densely punctate throughout. Sculpture of mesoscutellum: punctate rugulose throughout; smooth along midline, otherwise punctate rugulose. Dark bristlelike setae along transverse pronotal carina: absent. Sculpture ventral of transverse pronotal carina: finely punctate. Sculpture of femoral groove: smooth; striate in ventral end. Sculpture of ventral half of posterior mesepimeral area: smooth. Fine setigerous punctures on dorsal half of posterior mesepimeral area: present. Mesopleural carina: present along anterior half of femoral groove. Setation of ventral metapleural area: present throughout. Setation of metapleural triangle: dense. Color of legs: yellow throughout.

Color of metasoma: orange to black. Horn of T1: bulge smooth, at least anteriorly. Microsculpture of T2: absent. Microsculpture on T3: present. Macrosculpture of T3 medially: reticulate; absent. Macrosculpture of T3 laterally: reticulate rugose. Microsculpture of T4: absent. Macrosculpture of T4 laterally: rugulose. Punctation of T4: dense throughout; moderately dense throughout. Macrosculpture of T5: weakly rugulose laterally; absent. Punctation of T5: dense throughout; moderately dense throughout. Microsculpture of S3: absent. Macrosculpture of S3 laterally: absent.

Diagnosis.

Paridris mystax is one of the most distinctive species and can be easily identified by the dense setation throughout the ventral metapleural area and on the ventrolateral frons.

Etymology.

The epithet “mystax”, meaning "hair on the upper lip" in Greek, is given to this species for the conspicuous setation of the ventral frons.
