Diagnosis Larva: length between 7 and S mm; width ().!S mm; subcvhndrical in cross-section, tapering anteriorly; end segment inclined dorsoventrally (Figs 1 & 3): integuinent smooth and shining with segment boundaries clearly delineated. Head; oral lobes (sited between the antennomaxillary organs and the mouth) large and coated in transverse ridges (Fig. 2). Cephalopharyngeal skeleton (Fig. 12); pharsngeal sclerite lightly pigmented except for hyaline areas on cornua; dorsal bridge, dorsal apodeme and \entral pharyngeal ridges present; pharyngeal and intermediate scierites not fused; anterior end of intermediate sclerite heavily pigmented; parastoinal bars extending forward almost to mouth-hooks; mouth-hooks red-brown, blunt and without accessory teeth; posterior part of mouth-hooks quadrate in shape; dental scierites present. Thorax; anterior margin of prothorax folded down to meet head bearing longitudinal impressions or grooves (Fig. 2); anterior spiracles fan-shaped with 9-11 lobes (Fig. 10). Abdomen; each of the first six abdominal segments with locomotory organs comprising 5 rows of locomotory setae, the first two rows on the posterior margin of one segment and the remaining three on the anterior margin of the next segment (Fig. 4); second and fourth rows consisting of inclined groups of 3- 8 setae. End segment; with a pair of fleshy protuberances above the breathing tubes (Figs 1 & 3); anus with two lobes indented at tip and anus surrounded by round- tipped, spatulate. locomotory setae (Fig. 5); anteriomedial row of 4-6 setae larger.
