Diagnosis. Zenoria limitrophi sp. nov. has distinctive male genitalia. The structure differs from all other species in that the penis guide is as wide as long, while in other species it is much longer than wide, except Z. lativerpa González & Honour (2012) , which is as wide as long, but with its maximum width at the apex and not at the base.

Description of holotype, male. Length 3.9 mm; width 3.0 mm. Body oval, elongate, maximum width at basal third of elytra ( Fig. 1 ). Head, antennae, mouthparts, prothorax, legs and abdomen pale yellow; median basal mark on pronotum black, anteriorly rounded. Head with sparse yellowish-white pubescence. Scutellar shield black. Elytra dark metallic green with narrow humeral and apical pale-yellow margin, widened at apex; yellowish-white pubescence, sparse, except discal area with sparse brown pubescence ( Figs. 1–4 ). Margin of elytron broadly explanate, inner carina extending about ¼ distance to outer margin near elytral base. Meso- and metaventrite black. Abdominal postcoxal line curved posterolaterally, closely paralleling posterior margin of ventrite for short distance, then abruptly redirected anteriorly toward base of ventrite in lateral third ( Fig. 5 ). Posterior margin of ventrite V smoothly arched, convex. Posterior margin of ventrite VI with wide and deep semicircular emargination ( Fig. 6 ). Phallobase more than half length of tegminal strut, nearly two times longer than wide ( Fig. 7 ). Penis guide mamilliform, as wide as long at base, first third almost parallel-sided, sharply narrowed at midlength, subtriangular with rounded apex, with tubercules in apical third ( Fig. 8 ); curved in lateral view, basal half with keel on inner side, measuring 2/5 of its length, narrower ( Figs. 11–12 ). Parameres projecting beyond penis guide subtriangular in ventral view, curved inward and narrower in distal third, with short setae at apex ( Fig. 9 ), curved in lateral view in basal half and nearly straight in distal half; apex pointed ( Figs. 10–11 ). Penis normal wide, no more than 40 times longer than wide, semicircular in basal half; apical half straight ( Fig. 13 ); apex bifurcate with outer side short and blunt, inner side long, sharp and slightly curved downward ( Fig. 14 ); penis capsule with inner branch curved slightly inward and ending in a club, outer branch narrowing only near end, with outer membranous projection ( Fig. 13 ).

Female. Length 3.6 mm; width 3.0 mm. Similar to male except pronotum dark with narrow yellowish anterior and lateral margins, elytra lacking yellow humeral spot, apical spot shorter and narrower than in male ( Fig. 15 ). Ventrite VI with shallow emargination on posterior margin. Spermatheca J-shaped, cornu thickened toward distal end, with lamellar projection and barely visible basal ramus; nodulus extending in same direction as cornu, conical; accessory gland present; sperm duct long; infundibulum absent; apex of bursa copulatrix not modified ( Fig. 16 ). Coxites four times longer than wide, triangular; styli well developed ( Fig. 17 ).

Variation. Length 3.6–4.1 mm; width 3.0– 3.2 mm.

Etymology. From the Latin “limitrophus”, indicating their location near on the border between Brazil, Colombia and Peru.
