Description
Female body length: 2.60–4.00 mm (n=7). 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; rugose. Microsculpture of frons: absent. Sculpture of posterior vertex: punctate rugulose. Sculpture of gena: punctate rugulose. Basiconic sensillum on A7: absent.
Wings: macropterous, apex of forewing extending beyond posterior margin of T3. Length of R1: less than r-rs. Notaulus: percurrent. Color of mesosoma: dark brown to black. Sculpture of mesoscutum medially: densely punctate, with longitudinal rugae in posterior half; areolate rugulose. Sculpture of mesoscutellum: punctate rugulose throughout. Dark bristle-like 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: absent in area immediately below metapleural sulcus. Setation of metapleural triangle: dense. Color of legs: yellow throughout.
Color of metasoma: dark brown to black throughout. Horn of T1: bulge smooth, at least anteriorly; absent. Microsculpture of T2: absent. Microsculpture on T3: present. Macrosculpture of T3 medially: weakly longitudinally strigose. Macrosculpture of T3 laterally: reticulate rugose; longitudinally strigose. Microsculpture of T4: absent. Macrosculpture of T4 laterally: rugulose. Punctation of T4: sparse along midline, otherwise dense; dense throughout; moderately dense throughout. Macrosculpture of T5: absent; rugulose laterally. Punctation of T5: dense throughout; sparse medially, dense laterally. Microsculpture of S3: absent. Macrosculpture of S3 laterally: absent.
Diagnosis
The rugulose sculpture of the dorsal mesoscutum and mesoscutellum in Paridris nilaka is shared with Paridris rugulosus and Paridris toketoki; it may be separated from both by the dense, fine setation of the pronotal shoulder. Additionally, the typically black color of the body may be useful for identification, but should be used with caution given the color plasticity seen in many species.
Etymology
The epithet “nilaka” means “black” in Thai, and is used as a noun in apposition.
