Cercus in mediodorsal view: base of cercus without spine, medial expansion of cercus almost twice the width of the base and semicircular, without any long spine (some short spinules at the distal part), tip of cercus with sparse hair––like setae. Paraproct in lateral view: less than half the size of the cercus, with a tuff of pale setae directly upward. Paraproct in dorsal view: almost triangular with a spoon–like tip.

♀ —Basal plate not illustrated in Muzón (1997), pectoral color pattern as in Fig. 40A.
