Remarks

• Structure: Adult Female body semicircular, intersegmental constriction obviously marked. Derm membraneous except for sclerotized pygidial area. Cephalothorax slightly longer than abdomen. Pygidial margin with three deep grooves each with clusters of macroducts. Dorsal surface ducts: Marginal and submarginal occurring on pro- and metathorax, about 12-15 and 10-12 in number respectively. Marginal submarginal and median number of mactoducts on each segment of abdomen 1-7, distributed as follows: 18-20 on segment 1; 22-25 on segment 2; 12-14 on segment 3; 15-18 on segment 4; 12-15 on segment 5; 8-11 on segment 6; and 5-7 on segment 7. Marginal short setae on metathorax and abdominal segments 1-6. Few similar setae on head. Anal opening situated about 4 times its width from apex of pygidium. Antennae short, tuberculate, with 2 stout setae, of which one is quite long and curved. Ventral anterior spiracle with 8-10 trilocular disc pores; posterior spiracle with 10-13 disc pores. Macroducts equal in size to those on the dorsal surface. submarginally about 6-8 on metathorax, 4-5 on abdominal segment2; 6-8 on segment 3; and 5-7 on segment 4. Microducts of two different sizes. Three groups of larger microducts occurring marginally on metathorax and abdominal segments 1 and 2; each group with 3-5 microducts. Abundant small sized microducts scattered on cephalothorax, behind mouth-parts, and around and between the anterior and posterior spiracles. Few microducts medially on abdominal segments 1-3; numerous ones scattered over the pygidial area. A double row of submedian setae on abdominal segments 3-6. Perivulvar pores in 5 groups, medians 4-6, anterior laterals 8-11 and posterior laterals 4-6. First instar elliptical. Derm membranous except for sclerotized areas at the duct spot of head and the pygidial margin. Anal opening small, subapical. Two pair of sclerotized processes occurring lateral to caudal setae accompanid by anothr tubrcular process on each side. A pair of spinous processes between caudal setae. Second instar male broadly oval. Pygidium entirely without lobes. Derm membraneous except for pygidial area. Pygidial margin with 5 well developed grooves, separated by spinous processes fringed apically, each groove including a cluster of macroducts. Second instar female very similar to second instar male, differing by having only 3 grooves of macroducts at the pygidium and fewer macro- and microducts. The thorax appears devoid of macroducts. Spiracular disc pores more than three.
