Diagnosis.

The setose metascutellum of Paridris taekuli is known to occur in one other species of Paridris , Paridris spinosa Rajomohana, from India. Paridris taekuli lacks an occipital carina, has a postmarginal vein about as long as the stigmal vein, and an apically constricted T6. Paridris spinosa has an occipital carina dorsally, a punctiform postmarginal vein and an evenly convex T6.

Etymology.

This species is named after Charuwat Taekul, a friend, student and colleague of the authors, for his contributions to the taxonomy and systematics of Platygastroidea .

Comments.

Specimen OSUC 334142 lacked setae on the metascutellum, as well as on other parts of the body, following the DNA extraction process that we believe caused loss of setation. Because setation of the metascutellum is the most diagnostic character for this species, we exclude the male DNA voucher specimen from the paratype series. The three specimens from the Ivory Coast exhibit notable variability in some of the diagnostic characters, namely, the posterior margin of the metascutellum is slightly emarginate; the setation of the metascutellum is medially reduced; and the postmarginal vein is slightly longer than the stigmal vein wheras it is equal to or less than the length of the stigmal vein in specimens from Asia and Madagascar.
