Density of punctation on anterior medial mesoscutum: dense along mesoscutal suprahumeral sulcus, otherwise sparse. Reticulate microfissures on anterior half of medial mesoscutum: absent. Density of punctation on posterior medial mesoscutum: sparse. Notaulus: percurrent, reaching suprahumeral sulcus as a smooth furrow; percurrent, reaching suprahumeral sulcus as a line of punctures; abbreviate, not reaching mesoscutal suprahumeral sulcus. Orientation of notauli: parallel. Shape of notaulus at posterior apex: ovoid. Macrosculpture of mesoscutellum: punctate rugose along margins, smooth medially. Postacetabular sulcus: smoothly furrowed. Mesopleural carina: absent. Punctures on posterodorsal mesepimeral area: very fine; absent. Sculpture of mesopleuron anteroventral to femoral depression: smooth with punctures or rugulae along prespiracular sulcus. Sculpture of posterior mesepimeral area: smooth. Form of metascutellum in female: transverse punctate rugulose lamella, posterior margin approximately straight. Form of metascutellum in male: transverse punctate rugulose lamella, posterior margin approximately straight. Paracoxal and metapleural sulci: separate. Posterior margin of metapleuron below propodeal spiracle: with blunt angle near intersection with metapleural sulcus. Sculpture between metapleural triangle and metapleural sulcus: smooth. Sculpture of metapleural triangle: punctate rugose. Setation of metapleural triangle: sparse. Anterior propodeal projection: absent. Setation of metasomal depression: absent. Lateral propodeal area: raised above plical area and indicated by sparser setation. Plical carina: present. Shape of lateral propodeal area: continuous with prespiracular propodeal area. Sculpture of lateral propodeal area: rugose.

Color of metasoma: yellow; reddish brown; yellowish brown. Macrosculpture of T1: longitudinally striate. Interstitial sculpture of T1: smooth; finely rugulose. Adornment of horn on T1 in female: longitudinal median carina on dorsal surface, forming small point posteriorly. Macrosculpture of T2 in female: longitudinally striate throughout. Macrosculpture of T2 in male: longitudinally striate throughout. Microsculpture on T2: present. Setal patch of lateral T2: present throughout lateral surface of tergite. Posterior margin of transverse sulcus on T2: straight. Carina along posterior margin of transverse sulcus on T2 in male: present. Carina along posterior margin of transverse sulcus on T2 in female: present. Microsculpture on T3: present. Macrosculpture of T3 medially in female: weakly longitudinally striate. Macrosculpture of T3 laterally in female: longitudinally striate. Macrosculpture of T3 medially in male: weakly longitudinally striate. Macrosculpture of T3 laterally in male: longitudinally striate. Microsculpture on T4: absent. Macrosculpture of T4 medially in female: absent. Macrosculpture of T4 laterally in female: absent. Macrosculpture of T4 in male: absent. Macrosculpture of T5 in female: absent. Constriction of apical T6 in female: present. Punctation of T6 in female: densely and finely punctate throughout. Setation of S1: sparsely distributed throughout. Form of S2 felt field: longitudinal row or patch of setigerous punctures. Macrosculpture of S2 medially: longitudinally striate. Macrosculpture of S3: absent.

Wing development: macropterous. Basal vein in hind wing: spectral. Setation of hind wing: uniform throughout. Length of postmarginalis: approximately equal to length of stigmalis. RS+M in fore wing: spectral.

Diagnosis.

Paridris lemete is very similar to Paridris aenea . The additional basiconic sensillum present on A8 provides a straightforward character to separate the females of these species. Males of Paridris lemete are best separated from Paridris aenea by the smooth sculpture of the ventral mesopleuron.

Etymology.

The species epithet is derived from the Spanish phrase "le mete," slang in Puerto Rico for "it is awesome", which we which we consider to be appropriate for this species. The name is treated as a noun in apposition.
