description: <i>Tetralonioidella wuae</i> Niu &amp; Zhu, sp. nov. (Figs 20–22) Diagnosis. The new species has fore wing without papillae, just as that of <i>T. heinzi</i>, but the bristle-like setae on ventral surface S7 of male are denser than that of <i>T. heinzi</i>, pubescence on scutum and metasoma sparser than that of <i>T. heinizi</i>, yellowish-brown, not fox-red.
