Accessory claw exceptionally short: 92% shorter than the claw (Figure 3B). Preanal ring with a very short blunt projection, almost glabrous, only with 5 lateral setae (Figure 3C, D), subanal scale with two setae, anal valves with two long ventral setae on the lateral part of the posterior margin, rarely up to two additional setae were observed, however the number is variable and may even differ between right and left valve of the same specimen (Figure 3C). Male first pair of legs modified as typical of the genus, hook-like.
