Macrosculpture of T5 in female: absent. Constriction of apical T6 in female: absent. Setation of S1: densely present throughout. Form of S2 felt field: line of dense setae along longitudinal ridge.

Wing development: macropterous. Basal vein in hind wing: spectral. Setation of hind wing: uniform throughout. RS+M in fore wing: nebulous.

Diagnosis.

Paridris minor shares with Paridris convexa , Paridris gongylos , and Paridris laeviceps the presence of reticulate microsculpture throughout the head. The females differ from Paridris convexa most notably by the shape of T6 which is not constricted in its apical half and from the females of Paridris laeviceps by the complete notaulus. Males of Paridris minor may be separated from these speces by the combination of the complete notaulus, a non-crenulate occipital rim and antennomeres 6-11 that are less than 3 times as long as wide.

Etymology.

This species is named for its diminutive size. The Latin epithet “minor” is treated as a noun in apposition.
