Closely allied to P. hcegei Saussure and Pictet (Biol. Cent.-Amer., 

 Orth., I, p. 334), but differing in the form of the extremity of the 

 cerci which are strongly bidentate, the intermediate diastema being 

 considerably emarginate, while in P. hwgei the extremity is acute, 

 the additional lobe being rotundate. No affinity exists with P. 

 maya Saussure and Pictet, the cerci in that species being strongly 

 falcate, and terminally acuminate.
