Description. General colour light brown. Frons behind M-line brown (Fig. 19), often lighter along a median stripe, sides of frons and genae lighter; M-line yellowish ochraceous; lappets brown, frontoclypeus, in front of Mline, brownish; parietalia light brown, darker laterally and towards the middle, but at the middle an ochraceous spot traversed by the coronal line. Scape of antennae brown, pedicel ochraceous and brown, flagellum mostly light brown. Pronotum (Fig. 19) medium brown, lateral half somewhat darker. Membrane and veins of forewings light brown; C and Sc brownish basally, rest pale. Legs light to medium brown, coxae, trochanters and base of femora yellowish. Cercomeres pale brown with darker apices.
Male. Forewing length 12.8–17.0 mm (mean= 15.4 mm, N=51). Tergum 10 (Fig. 20) pale medially and at bases of cerci, most sensilla basiconica carrot-shaped (Fig. 22). Projecting part of the subgenital plate (Fig. 23) about twice as broad as long; hammer roughly pear-shaped; basally from hammer, an ochraceous stripe; subgenital plate mostly whitish. Sternum 9 antero-laterally from plate brownish ochraceous. Paraprocts (Fig. 21) finger-like, without a subapical denticle; apical sensillae with sparse minute hairs. Penial tube with pair of lateral spinose patches near armature (Fig. 24). Basal ring of armature moderately broad (Figs. 25–27), hooks making a compact curve, inner curve distally with crenulations.
Female. Forewing length 18.6–22.1 mm (mean=20.5, N=9). Outer contour of subgenital plate (Fig. 28) rounded with a small apical notch. Plate light brown to ochraceous. Sternum 9 (Fig. 30) with two slightly sclerotized wedges on each side. Numerous microtrichia on connecting membrane between sternum 9 and 10. Egg (Fig. 31). Oval, obtuse. Eggs taken from the body of a female measured 0.39–0.40 x 0.21–0.22 mm. Those from an egg pack from another individual, 0.34–0.36 x 0.18–0.19 mm.
Remarks. Kempnyia tupinamba belongs to a group of species that has a comma-shaped, spiny patch on the penial tube basal to the armature. The other species are K. sazimai Froehlich, 1988, K. umbrina Froehlich, 1988 and K. vanini Froehlich, 1988. Kempnyia sazimai is the largest, with a forewing length of 19.4 mm in the male, but is lighter in colour than K. tupinamba. Both K. umbrina and K. vanini are smaller, with a mean male forewing length of around 12 mm. Kempnyia vanini is ochraceous, while K. umbrina is brown and, as such, more similar to K. tupinamba, but the tip of the paraproct is angled and the peg bristles are short elliptical.
Etymology. The species is named for the Tupinambá Indians that lived on the Brazilian coast from the east of São Paulo State northwards.
