Tamesse J.L. and Dayang L.D.

Abstract:
Background and Objective: Jumping plant lice or psyllids are phloem-feeding insects, mostly associated with angiosperms. Psyllids of the Diclidophlebia genus are pest of some important plants in Africa in general and Cameroon in particular. The aim of this study was to describe a new species of Diclidophlebia genus feed on traditional medicinal plant in Africa, Grewia venusta (G. venusta) Fresen, (Tiliaceae). Materials and Methods: 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. Results: Adult forewing membrane smooth without setae; spinules present in all cells, covering cells up to veins, excluding c+sc cell which are covering in three quarter length posterior. All veins bearing conspicuous setae. Metatibia bearing an incomplete crown of 6 sclerotized apical spurs grouped as 4+2 and 4 slender unsclerotized setae. Male genitalia with prostiger simple and tubular slightly enlarged and apex truncated. Inner face of Paramere with two short setae robust at the basal part. Subgenital plate of female pointed apically. Fifth instar larvae stages were observed. Antenna 10-segmented with a single subapical rhinarium on segment 4, 6, 8 and 9. Following number of sectasetae were on each segment: 1(0); 2(1); 3(1); 4(2); 5(0); 6(3); 7(0); 8(1); 9(1); 10(0). Tarsal arolium without unguitractor. Conclusion: Taxonomic studies of the psyllid indicated that, Diclidophlebia andjigae sp.n. is a new psyllids species of Liviidae family described from Adamawa Region of Cameroon.
