Author: Reiss, 1969
Diagnosis
Exuviae 3.3-4.5mm long (n=3).
Cephalothorax: Cephalic tubercles rounded shallow mounds; frontal setae 70, 115µm long (n=2). Antennal sheath base with a barely perceptible swelling. Thoracic horn 163-400µm long (n=5); ThR 6.5-10.2 (n=4). Thoracic horn seta 100-120µm long, 0.31-0.61 of horn length (n=4). Posterior thoracic mound swollen hemispherically with a finger-like projection posteriorly. Pearl row absent.
Abdomen: Length hook row II 0.36-0.39x width tergite (n=5); hooks 86-102 (n=6). Tergite II without anterior point patches. The transverse point patches are only weakly developed. Tergites IV and V nearly covered with strong points, the points of the anterior transverse point patches similar in size but more dense than elsewhere on these segments and may be rendered conspicuous by a golden or brown colouring of the cuticle around them. Tergites VII and VIII with very restricted armament or smooth. Pleura of mid-abdominal segments extensively armed with small points. Pedes spurii B of segment II conspicuous. Comb of segment VIII 25-35µm wide (n=5); with 2-7 marginal teeth (n=6). Lateral taeniae of segments IV-VIII: 2,3,4,4,5.
Anal segment: Anal lobe ratio 0.90-1.43 (n=5). Fringe of anal lobe complete, with 23-31 taeniae (n=7).
