Abstract: Two new species of the large pantropical jumping plant-louse genus
Pseudophacopteron Enderlein, 1921 (Hemiptera: Psylloidea: Phacopteronidae) are
described from dry woodland habitats in the Midwest, Southeast and South of
Brazil. Pseudophacopteron aspidospermi sp. nov. is associated with Aspidosperma
australe, P. longicaudatum sp. nov. has been found on Aspidosperma macrocarpon
and A. tomentosum (Apocynaceae). Both species induce intralaminar lenticular
galls on the leaves of their host trees which have been the subject of several
structural, histochemical and ecological publications. Adult males and females,
fifth instar immatures and galls are illustrated including diagnostic
morphological details, and compared with other Neotropical and Old World species
of Pseudophacopteron and Phacopteronidae. The distribution of Pseudophacopteron
in the Neotropical Region is briefly discussed.
