Organism information awaits expert curation
Class: Arachnida

Size: Female Idiosomal length: 300-340 µm; Idiosoma (dorsal) 302 µm long, 211 µm wide; Anterodorsal plate (AD) 89 µm long, 71 µ wide; Ocular plate (OC) 70 µm long, 46 µm wide; Posterodorsal plate (PD) 172 µm long, 120 µm wide; Anterior Epimeral plate (AE) 95 µm long, 164 µm wide; Genitoanal plate (GA) 140 µm long, 87 µm wide; Genital opening (GO) 71 µm long, 38 µm wide; Gnathosoma 105 µm long, 67 µm wide.

All dorsal plates separated by wide cuticular membranous area AD with three areolae viz. one anterior and two posterior. The feebly developed pores of the areolae arranged longitudinally. The costae swollen laterally behind the 4th leg insertion. The costae also bear a pair of adenal seta present on either side of the anal papillae. All the ventral plates separated by cuticular membranous AE without ventral areolae, ventral plates sculptured with pycnotic pores. AE with 3 pairs setae. PE with 3 ventral and dorsal setae. AE and GA separated by a wide cuticular membrane. GA longer accounting for more than ½ the ventral idiosomal length. GA bears 3 PGs on each side of the GO besides paragenital areolae. The longer, occupying nearly half the total area of GA. The distance between the anterior margin of GA and that of GO lesser than GO length. A pair of genital sclerites bearing a pair of setae anteriorly guarded by GO.
