Remarks.

Attems (1938) described this species as Glyphiulus dubius , based on a single female (holotype) collected at Angkor, Cambodia. Mauriès (1983) regarded this species as being very similar to P. boutini Mauriès, 1970. The major difference is that P. dubius has dorsal crests divided into three tubercles starting with body segment 6, vs body segment 7 in P. boutini . However, the status of the species is still doubtful, as the gonopodal structure remains unknown. Hoffman (1977) called for a search of male topotypes to clarify the species’ identity.
