The eye capsules in some young specimens well developed and somewhat projected over the idiosoma margin (Fig. 43). Glandularia greatly enlarged and projected with well-developed papillae, and encircled by platelet. Chitinous platelets and glandularia on dorsum and ventrum as showed in Fig. 43 and Fig. 44. Coxae in four groups, surface of coxae reticulated. ACG 152 (151-157) in length, posterior apodeme indistinct. Anterior tip of CxI with a tuft of hair-like setae. E2 laterally between ACG and PCG. PCG 167 (164-175) in length. Glandularia absent from CxIII. Approximately two-thirds of genital field lying between PCG. Genital valves not covering the genital acetabula, 176 (174-188) in length, 145 (143-152) in width. One round platelet in front of genital field. Pre- and postgenital sclerites small. Three pairs of small and rounded genital acetabula, the second pair much close to the third one and far away from the first one. V1 on sclerites in medium size and without accompanying glandularia. Excretory pore lying between V1 and V2 and on a protuberance surrounded by a well-developed sclerotized ring.</paragraph>
