Diagnosis (material leg. J.-N. Tourenq)
Exuviae 6.5mm long (n=2).
Colour: Golden-brown to dark brown. Contrast in colour between thorax and abdomen not so strongly marked: specimens dark anteriorly also have the abdomen infuscated; outer margin of the anal lobes coloured except at base.
Cephalothorax: Cephalic tubercles LxB 88x56, 90x60µm (n=2). Frontal setae 48µm long (n=1). Basal ring of thoracic horn 108x42, 124x50µm. Tracheolar patch of thoracic horn without an "eye", patch 80x28, 88x26µm (n=2). Thoracic granulation usually extensive.
Abdomen: Hook row II entire, length of row 0.43x width tergite (n=1); hooks 66, 68 (n=2). Armament of tergites II-VI not strongly waisted and with the posterior transverse band not successively increasing in extent to tergite VI; usually reduced on VI. Sternites III and IV with the lateral bands spreading inwards and only narrowly joined anteriorly. Parasternite II not obviously shagreened. Pleura of segment IV spinulate. Comb of segment VIII with 1 sturdy finely apiculate tooth, set on the end of an elongate ventral cuticular mound which exceeds appreciably the apico-lateral corner of the segment. Lateral taeniae of segments V-VIII: 4,4,4,5.
Anal segment: Anal lobes strongly rounded; each lobe with 47, 55 fringe taeniae (n=2).
