Description. Dorsum of typical form medium green, often with scutellum, head, connexivum, and anterior third of pronotum pale; punctation dense, shallow, ru gulose, usually less dense on hemelytra; punctures green. Ventral surface pale green to yellow, each posterior abdominal angle black; punctures less dense than on dorsum, concolorous with surface. Antennae pale to medium green or brown, apical two segments usually darker. Legs pale tomedium green, apices of tibiae often becoming fuscous. Dorsum of brown form light tan to brown, often tylus and area of head between ocelli darker, usually with pale mesial line on scutellum, this line often extending onto pronotum. Dorsal punctation concolorous with surface except on hemelytra, scutellum, and anterior and posterior margins of connexival segments, fuscous. Ventral surface pale brown with fuscous punctures; a series of black post spiracular spots usually present; anterior and posterior abdominal angles black. An tennae pale to medium brown, apical two segments usually fuscous. Legs pale to medium brown with numerous fuscous spots scattered over surface. Total length excluding membrane 5.1 - 7.7 mm.

Head declivent, broadly rounded apically, jugal margins distinctly sinuate, sub parallel for middle third of distance from eyes to apex (see Rolston, 1972, fig. 37); juga equalling or usually slightly surpassing tylus. Length of head from apex to posterior margin of ocellus 1.1 - 1.5 mm, width across eyes 1.6 - 2.0 mm. Distance from ocellus to nearest eye equal to or usually greater than twice the diameter of ocellus, distance 0.18 - 0.22 mm, ocellar diameter 0.07 - 0.11 mm. Antennal segment 3 much shorter than segments 2, 4, or 5, length of segments 1- 5 about 0.2 - 0.3, 0.5 0.8, 0.4 - 0.5, 0.5 - 0.6, 0.7 - 0.8 mm.

Pronotum 3.6 - 4.8 mm wide at humeri, mesial length 1.2 - 1.7 mm. Humeral angle rounded, scarcely produced beyond base of corium. Anterolateral margin of prono tum slightly concave, carinate for posterior half only (see Rolston, 1972, fig. 38). No black on cicatrices.

Scutellum usually slightly wider than long, width at base 2.2 - 2.9 mm, mesial length 2.1 - 2.9 mm. Scutellar tongue broader than long, width at base 1.0 - 1.4 mm, mesial length 0.9 - 1.3 mm, margins nowhere parallel, tapering to an evenly rounded apex. Width across abdomen nearly as wide as width across humeri. Membrane vitreous, usually with flecks of fuscous scattered along veins.

Ostiolar ruga long, distance from mesial margin of ostiole to apex of ruga greater than distance from apex of ruga to lateral margin of supporting sclerite, ruga eva nescent apically, canal not widening apically. Rostral segments 2 - 4 about 0.8 - 1.0, 0.5 - 0.6, 0.5 - 0.6 mm long.

Posterior margin of pygophore concave on each side of middle with a mesial v-shaped emargination; ventral surface of pygophore without carina. Head of par amere bilobed, lateral lobe small, directed laterally and usually bent weakly toward anterior lobe; anterior lobe bent slightly laterally, narrowed apically (see Rolston, 1972, fig. 42). Female genital plates typical for the genus.

Distribution. Western United States and Mexico.

Etymology. This species is named for the late E. P. Van Duzee, whose work has contributed much to the understanding of this genus and tomany other hemipteran genera.

Remarks. All the species included in Tepa appear quite similar superficially. Tepa vanduzeei can be separated from T. brevis , T. rugulosa , and T. yerma by the longer ostiolar ruga. In T. jugosa the ostiolar canal widens apically. Tepa vanduzeei ismost closely related to T. panda from which it can be separated reliably only by the male genitalia. The anterior lobe of the paramere is narrowed apically in T. vanduzeei ; it is evenly rounded in T. panda.

Tepa vanduzeei is the species that most previous workers have called T. puncti ventris. Most specimens inmuseums labeled as T. punctiventris will probably be this new species.
