Two new species of larval Erythraeidae (Parasitengona) ectoparasites of leafhoppers from Southwestern China

In this study, three species were examined. Among them, two new species, <i>Caeculisomataianensis</i> <b>sp. nov.</b> and <i>Iguatoniabarboproxima</i> <b>sp. nov.</b> from Southwestern China, were described and illustrated based on larvae. The two new species can be distinguished from the known species by the following characteristics: the anterior sensilla are nude, and the gnathosoma has two pairs of nude hypostomalae in <i>C.taianensis</i> <b>sp. nov.</b>; the anterior sensilla and posterolateral scutalae are located in the posterior half of the scutum, and the posterior hypostomalae with barbs on the proximal half in <i>I.barboproxima</i> <b>sp. nov.</b> In addition, a new host and distribution range of <i>Abrolophusquadrapexicis</i> Xu & Jin, 2022 is reported.
