Taxonomy of a new jumping plant lice, Trioza funtamae sp. nov. (Hemiptera: Triozidae), associated with Funtamia elastica (Preuss) Stapf, 1901 (Apocynaceae) in Cameroon

The aim of this work is the description and identification of the psyllid associated with Funtumia elastica in Cameroon, and thus contribute to the psyllid biodiversity study in Cameroonian fauna. The study was carried out in different localities of Cameroon, from January 2006 to December 2020. Psyllids feeding on the host plant Funtumia elastica, were captured with a sweep net of 0.5 mm mesh size and an aspirator. Drawings and measurements were made from slide-mounted material. The psyllid of Funtumia elactica, Trioza funtumae sp. nov., is characterized by: a stage V larva, humeral lobe extends above the eyes; circular tarsal arolium, circumanal in the shape of a circle arch with a single row of pores and bulging at both ends; adults, hindwing bears sixteen simple setae on the costal and sub-costal veins, metatibia has 4 apical spurs, base of the metatibia is devoid of spines, parameters slightly tubular-shaped with its narrowed and curved apical third, distal portion of the aedeagus in the shape of a tablespoon, apex of the ventral valve rounded and pointed. Comparing Trioza funtumae with the specimens recorded previously elsewhere, it is morphologically different from them and can be reported as a new specie in the Trioza Foerster, 1848 genus.
