The head, prothorax, mesothorax, metathorax and smoothly surfaced abdomen were clearly recognized. A pair of eyes having several facets occupied the base of the antennae. The posterior part of the eye possessed a projected ocular tubercle. Clypeus and labrum positioned to anterior lower part of the head. The clypeus joint with the labrum at its lower portion as a separated organ. The rostrum originates bellow the labrum and had a length of 310-480 μm. The stylets were projected from the underside of labrum and were inserted into the basal and middle portion of the rostrum. Rostrum had three segments and a suture in the middle region extended up to the apex. A tube-like canal was found at the middle part of the rostrum. The inserted stylets were projected from the apex and diverted in three directions. The middle portion of the stylets was thick and laterals were thin having sharp tips. The stylets were 460-630 μm long and having a diameter of 2.5-3 μm.]]>Dixon, A.F.G.,19831297314Eastop, V.F.,19726157178Escudero, J., A. Acosta, L.V. Ramirez, I.B. Caloni and G.R.
