Description
Male body length: 2.35 mm (n=1).
Color of head: black. Distal margin of clypeus: smooth. Width of clypeus: equal to or less than width of interantennal process. Lateral corner of clypeus: rounded. Development of interantennal process ventrally: connecting with clypeus. Number of mandibular teeth: three. Length of mediofacial striae: extending to dorsal frons. Shape of gena in dorsal view: moderately receding behind compound eye. Striae on gena: pronounced. Length of striae on gena: extending above ventral margin of eye. Distribution of microsculpture on head: absent. Length of OOL: less than 2 ocellar diameters. Occipital carina above foramen magnum: present. Anterior margin of occipital carina: comprised of medium to large sized cells. Setation of postgena: sparse. Ventral extent of occipital carina: extending to base of mandible.
Color of mesosoma: reddish brown. Dorsal half of pronotal cervical sulcus: present as line of small to minute cells. Ventral half of pronotal cervical sulcus: present as line of small to minute cells. Transverse pronotal carina: present in posterodorsal corner of pronotum. Shape of pronotal shoulder in dorsal view: without dorsal surface. Form of pronotal suprahumeral sulcus: punctate rugulose. Macrosculpture of anterior medial mesoscutum: absent. Density of punctation on anterior medial mesoscutum: dense throughout. Reticulate microfissures on anterior half of medial mesoscutum: absent. Pustulate microsculpture on anterior mesoscutum: absent. Density of punctation on posterior medial mesoscutum: sparse. Notaulus: present as cluster of punctures at posterior margin of mesoscutum. Macrosculpture of mesoscutellum: punctate rugose. Postacetabular sulcus: crenulate. Mesopleural carina: absent. Punctures on posterodorsal mesepimeral area: absent. Sculpture of mesopleuron anteroventral to femoral depression: densely punctate anteriorly, smooth posteriorly and on ventral surface. Sculpture of posterior mesepimeral area: smooth. Form of metascutellum in male: bispinose. Paracoxal and metapleural sulci: uncertain, separate. Posterior margin of metapleuron below propodeal spiracle: straight to moderately convex. Setation between metapleural triangle and metapleural sulcus: absent. Sculpture between metapleural triangle and metapleural sulcus: punctate rugose. Sculpture of metapleural triangle: punctate rugose. Setation of metapleural triangle: sparse. Anterior propodeal projection: absent. Setation of metasomal depression: absent. Lateral propodeal area: indicated by sparser degree of setation. Plical carina: absent. Shape of lateral propodeal area: continuous with prespiracular propodeal area. Sculpture of lateral propodeal area: rugose.
Color of metasoma: brown. Macrosculpture of T1: longitudinally strigose. Interstitial sculpture of T1: smooth. Macrosculpture of T2 in male: weakly longitudinally striate throughout. Microsculpture on T2: absent. Setal patch of lateral T2: present throughout lateral surface of tergite. Posterior margin of transverse sulcus on T2: weakly convex. Carina along posterior margin of transverse sulcus on T2 in male: absent. Microsculpture on T3: absent. Macrosculpture of T3 medially in male: weakly longitudinally striate. Macrosculpture of T3 laterally in male: weakly longitudinally striate. Microsculpture on T4: absent. Macrosculpture of T4 in male: absent. Setation of S1: absent. Form of S2 felt field: longitudinal row or patch of setigerous punctures. Macrosculpture of S2 medially: absent. Macrosculpture of S3: absent.
Wing development: macropterous. Basal vein in hind wing: spectral. Setation of hind wing: uniform throughout. Length of postmarginalis: less than half of length of stigmalis. RS+M in fore wing: nebulous.
Diagnosis
Paridris armata is not acutely similar to any of the other Paridris species in the New World. The bispinose shape of the metascutellum and very narrow clypeus unambiguously separate it from the other species treated here.
Etymology
The adjectival Latin epithet “armata” is given to this species for the shape and relatively large size of the metascutellum.
