The new jumping plant-louse especies: Diaphorina dangoensis sp. nov. (Hemiptera, Psyllidae) associated with Strychnos spinosa (Loganiaceae) in Cameroon

Diaphorina is a species-rich genus, native to the tropics and subtropics of the Old World, particularly of more arid regions including Cameroon. The aim of this study was to describe a new species of Diaphorina genus associated to traditional medicinal plant in Africa, Strychnos spinosa (Loganiaceae). Adult psyllids were captured with a sweep net of 0.5 mm mesh size and a mouth aspirator then preserved dry and slide mounted or in 70% ethanol. The species was identified under stereomicroscope, drawing and measurements were made from slide mounted material. Adult forewing coloration with yellowish hyaline membrane densely covered with irregular dark brown markings maculated; six clear spaces present at the apical margin, one yellowish lunate area at apical margin in each cell, r1, r2 and m1, two small yellowish lunate area in cell Cu1; one longitudinal yellowish stripe in cell m2 in the apical part. Inner face of paramere with a small tooth, just below, a cluster of stout setae present, pointed downwards, bearing a other cluster of long setae pointing outward. Subgenital plate of female with basal margin broad and truncated obliquely, tip of ovipositor blunt. Fifth instar larvae with wing-pads bearing small simple setae along the margin; tarsal arolium triangular more wide than long with sligth depression into median part; third segment antenna, bearing three lanceolate setae and five simples setae. Taxonomic studies comparing with species previously described indicated that, Diaphorina dangoensis sp. nov. is a new psyllids species of Psyllidae family described from Cameroon. published by the Journal of Biodiversity and Environmental Sciences | JBES
