Merus longer than carpus, widening distally, and with one spiniform distal seta and scattered setules and cuticular scales. Carpus twothirds as long as propodus, with one spiniform seta and cuticular scales. Propodus with serrated dorsal margin, with one dorsodistal seta, dorsal spine, and two spiniform ventral setae. Dactylus and unguis incompletely fused to a claw and combined shorter than propodus. Dactylus with ventral serration longer than ungius. Unguis with bifurcate tip (not visible on illustration due to appendage orientation).
