DIAGNOSIS: Flagellum 11­segmented. Sc long, ends at R between RS and r­m bases. Base of M 3+4 and CuA fork at level of r­m. Fore leg with tibia equal to femur or slightly longer.

DESCRIPTION: Body length = 2.34 mm (holotype)/ 2.88 mm (paratype); wing length = 1.75 mm (holotype)/ 2.20 mm (paratype). Head: Three ocelli in line, distances between median and lateral ones, and between lateral and eye margin, are equal. Face rectangular, bare. Clypeus bare. Scape and pedicel round­ ed, shorter than flagellomeres. Flagellum 11­ segmented, flagellomeres cylindrical, with lengths 2Χ width. Two palpomeres seen, apical one 2Χ length of basal. Thoracic sclerites bare. Scutum with long lateral setae and numerous short ones, not arranged in rows. Proepimeron small, fits in shallow incision on katepisternum. Anepisternal suture declines backward. Metepisternum touches anepimeron. Meron large. Wing: Costa ends beyond tip of R 5, more than one­third length between tips of R 5 and M 1. Sc long, ends at R between RS and r­m bases. Length of R 1 2.5–3Χ that of r­m, M3 section twice that of r­m. Length of fork of M 1 and M 2 2.5–3Χ M3 section. Base of fork of M 3+4 and CuA at level of rm base. Legs: Fore coxae with short anterior setae, hind coxae with long posterolateral setae. Fore leg with tibia equal to femur. Tibial spurs 1.2–1.5Χ tibial diameter. Abomen setose. Seventh segment very narrow. Gonocoxites massive, with apices blunt.

MATERIAL: Holotype AMNH NJ­117k, male; paratype NJ­117l, male in the same piece. USA: New Jersey, Sayreville, coll. P. Nascimbene.

ETYMOLOGY: The species epithet is derived from Latin Nova Caesarea meaning ‘‘New Jersey’’ and is a reference to the state of origin of the amber.

COMMENTS: The species is similar in venation to Docosia baisae Blagoderov, 1998 and D. zaza Blagoderov, 1998 , by proximal position of the forked base of M 3+4 and CuA, but differs from the latter species in having Sc long and M3 section short.
