Description.

Female body length: 2.35-2.40 mm (n=2). Color of head: reddish brown. Ventral clypeal margin: serrate. Sculpture of frons medially: mostly smooth with faint dorsoventral striation. Sculpture of frons immediately ventral of median ocellus: dorsoventrally strigose laterally. Microsculpture of frons: absent. Sculpture of posterior vertex: irregularly rugulose. Sculpture of gena: irregularly rugulose. Basiconic sensillum on A7: absent.

Wings: brachypterous, apex of forewing ending before T4. Notaulus: percurrent. Color of mesosoma: variably yellow to brown. Sculpture of mesoscutum medially: areolate rugulose. Sculpture of mesoscutellum: areolate rugulose. Dark bristlelike setae along transverse pronotal carina: absent. Sculpture ventral of transverse pronotal carina: rugulose posteriorly. Sculpture of femoral groove: 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. Setation of ventral metapleural area: absent in area immediately below metapleural sulcus. Setation of metapleural triangle: moderately dense. Color of legs: yellow throughout.

Color of metasoma: reddish brown. Horn of T1: bulge smooth, at least anteriorly; absent. Microsculpture of T2: present. Microsculpture on T3: absent. Macrosculpture of T3 medially: longitudinally strigose. Macrosculpture of T3 laterally: longitudinally strigose. Microsculpture of T4: absent. Macrosculpture of T4 laterally: rugulose. Punctation of T4: sparse along midline, otherwise dense. Macrosculpture of T5: absent. Punctation of T5: moderately dense throughout. Microsculpture of S3: absent. Macrosculpture of S3 laterally: absent.

Diagnosis.

Paridris reptilis and Paridris ferus are the only known brachypterous species in the Paridris nephta group. Paridris ferus has a basiconic sensillum on A7 and lacks interstitial microsculpture on T2. Paridris reptilis does not have a sensillum on A7 and T2 is densely microsculptured.

Etymology.

The adjectival epithet “reptilis”, meaning “crawling” in Latin, refers to the reduced wing size in this species.
