Abstract： One new species in the genus Tetradinodula Zha,2017 is described and illustrated with photographs.Tetradinodula strictivertex Mao&Li sp.nov.is similar to T reticulata Mao&Li,2020,but differs from the latter in:1)vertex 1.7 times as wide as one eye(2.9 times in T.reticulata);2)vertex nearly at the same level of upper margin of eyes(vertex markedly surpassing the upper margin of eyes in T.reticulata);3)antenna with middle segments about 5.2 times as long as wide(3.1 times in T.reticulata);4)lateral ocellus situated slightly below the middle of inner margin of eye(lateral ocellus placed slightly above lower margin of eyes in T.reticulata);and 5)external lateral carina of pronotum nearly straight(external lateral carina strongly curved in T.reticulata).
