— Frons about as wide as an eye; length of frons shorter than length of face; tibia reddish yel- 
low; fore claws and pulvilli about !/2 as long as 5‘ tarsomere; tergites 3 and 4 without dis- 
cal setae. — Genitalia (fig. 1 in SHmma 1981: 56): Cerci and surstylus more slender than in P 
margaretae; cerci in dorsal view evenly narrowed to apex, distance from base of suture to 
apex about 3 times the width of cerci at middle, weakly separated from each other in apical 
3/5, in lateral view almost equally broad in its whole length and weakly curved ventrally. 
Surstylus in lateral view at middle about 1.5 times as broad as cercus at that point, weakly 
narrowed to apex. Distiphallus in apical portion distinctly curved ventrally. ............
