We describe and illustrate in detail species of genus Jaltomata Schletdl. (Solanaceae) from La Libertad Region and a new taxon from northern Peru. We report 14 species, all from Peru: J. calliantha, J. sanchez-vegae, J. ventricosa, J. grandibaccata, J. dendroidea, J. bernardelloana, J. salpoensis, J. nigricolor, J. lezamae, J. pauciseminata, J. yungayensis, J. mionei, J. truxillana & J. angasmarcae. Five of them have red nectar. We describe a new taxon, J. aricapampae, which is found in the surroundings of Aricapampa, Chugay-Chagual route, province of Sanchez Carrion, region of La Libertad, Peru, at 7º48’57.9" S and 77º43’53.5" W, 2720 m of altitude. It shows 6-8 flowers per node, corolla with short tube and very rotate limb, 10-lobed, creamy white externally and internally, pubescent surrounded by a layer of transparent simple ramified hairs externally, free portion of the staminal filaments creamy white surrounded by a dense layer of transparent simple eglandular hairs which cover 60-70 % of the basal area, style creamy whitish, (20-) 71-90 seeds per berry, shrubs 0.70-1.2 m tall.
