Paridris nitidiceps  (Kieffer): Masner 1965: 89 (type information).


Male body length: 1.86 mm (n=1).

Shape of male flagellomeres: longer than wide by a factor less than 2.

Color of head: dark brown. Distal margin of clypeus: serrate. 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: absent. Microsculpture of posterior gena: absent. Ventral extent of occipital carina: extending to base of mandible.

Color of mesosoma: reddish brown.

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

Anterior notaulus: reaching mesoscutal suprahumeral sulcus as continuous furrow. Shape of posterior notaulus: ovoid. Microsculpture on anterior half of medial mesoscutum: absent. Macrosculpture of anterior medial mesoscutum: absent. Pattern of punctation density on medial mesoscutum: uniform throughout.

Punctures on dorsal part of posterior mesepimeral area: present. Size of punctures on dorsal part of posterior mesepimeral area: large. Postacetabular sulcus: crenulate. Striae ventrad of mesopleural carina: absent.

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

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

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

Color of metasoma: reddish brown. Patch of dense fine setae on anterolateral T1: absent. Macrosculpture of S1: longitudinally striate. 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.


Paridris nitidiceps  has conspicuous glabrous punctures throughout the posterior mesepimeral area, a rather uncommon character for Paridris  . It is on the basis of this and the percurrent notaulus that we separate it from Paridris densiclava  .
