Diagnosis. Dorsal shield reticulated, with two pairs of glandularia and two pairs of setae without glandularia. Vgl- 4 fused separated from ventral shield in male, but fused in female.

Description. Colour yellowish. Dorsal shield reticulated laterally, with two pairs of glandularia and two pairs of setae without glandularia; postocularia anterior to dgl- 1. Genital field with acetabula lying in a triangle.

Male: Idiosoma 466 long and 340 wide. Excretory pore indistinct. Dorsal furrow with three pairs of glandularia, a pair of small platelets with a seta and two pairs of slit organs. One pair of slit organs fused with posterolateral edge of dorsal shield. Gonopore 62 long. Length/height of P 1 –P 5: 25 /17, 45/29, 34/24, 66/20, 30/ 10; P 4 relatively long. Length of I-leg- 4–6: 60, 62, 44. Length of IV-leg- 4–6: 88, 90, 68; IV-legs relatively long and strong. Legs without swimming setae.

Female: Idiosoma 454 long and 348 wide. Dorsal shield 437 long and 300 wide posterior pair of slit organs lying free in the dorsal furrow. Pair of glandularia between IV-leg sockets and genital field not visible. One large egg present, 116 in diameter. Length/height of P 1 –P 5: 22 /17, 46/32, 35/25, 68/20, 30/ 10.
