Abstract:
Jumping plant lice are phytophagous insects which induce damages to their host plants. The
biodiversity of Cameroonian psyllid fauna is important but many species remain unknown.
Euryconus dialia sp. nov. is associated with Dialium sp. a valuable timber tree in which the
psyllid induces necrosis of leaves especially young plants. The aim of this work is the describe
and identify the psyllid associated with Dialium sp. in Cameroon, a contribution of the psyllid
biodiversity study in Cameroonian fauna. From the description E. dialia sp. nov. is characterized
by forewing pattern in which the surface is covered by large brown band which is darker on the
distal portion of the wing and on c+sc cell, a light white area covered the third surface of c+sc
cell on the proximal portion and another light white area is surrounding half of the Rs vein;
internal veins carrying dark patches except M2+3 and R+M+Cu veins. Genal processes well
developed and broad anteriorly slightly incised forming two tubercles on the apex. Terminal
abdominal margin with 4+4 truncate sectasetae; anus oval, in terminal position; circumanal ring
consisting of a single row of pores; additional pore fields developed, convulted, extending much
onto abdominal dorsum and consisting of a single row of wax pores. Comparing E. dialia with
the specimens recorded previously elsewhere it is morphologically different from them and can
be reported as new species in the Euryconus genus. |
