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, Caeculisoma taianensis sp. nov. and Iguatonia barboproxima sp. nov. 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 C. taianensis sp. nov.; 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. barboproxima sp. nov. In addition, a new host and distribution range of Abrolophus quadrapexicis Xu & Jin, 2022 is reported.
