Abstract: Nymphs of five Mongolian Tingidae, namely A.calypta elegans Horv. (4th instar), S phaerista paradoxa (Jak.) (4th and 5th instars), Dictyonota salsolae Gol. (5th instar), Lasiacantha kaszabi Hob. (5th instar), Tingis pilosa antennalis (Put.) (5th instar) are newly described and figured, and notes on nymphs of Dictyonota tricornis (Schrnk.) (5th instar) and Tingis ampliata (H.-S.) (4th instar) are given. A key to identification of older instar nymphs of 30 tingid species is included, which represents about 55 % of species of Tingidae known from the territory of Mongolia. The fact that larval spiniform processes do not in any way participate in the formation of paranota or hemelytra of the adult stage is ascertained from materials of nymphs of Lasiacantha kaszabi Hob.
