description: Key to known species of Phymastichus (females)   
 1 Syntergum without strong step-like carina. The cubital and subcubital setal lines of the forewing distinctly separate until approximately the apex of the trailing edge of the forewing (the longitudinal non-setose region at the very posterior of the forewing extends approximately the entire length of the trailing edge of the wing) (as in Figs 1d; 3a,d). Ovipositor not exposed. Coxae of all legs dark, of similar color to body....................................................... P. coffea   
- Syntergum with strong step-like carina, giving the apex of the gaster a crimped appearance dorsally (Figs 1a,b,e,f; 3 h). Non-setose region at the very posterior of the forewing between the cubital and subcubital setal lines extending between half the length of the wing to the full length of the trailing edge of the wing. Ovipositor exposed or not exposed in dry specimens. Procoxae of similar color to body, meso- and metacoxae distinctly lighter in color than body, metacoxae yellow to translucent white (Fig. 1a,e)............................................................................................... 2  
 2 Scale-like sculpture anterior to carina on the syntergum, and posterior to the carina, cuticle covered with a thick tuft of lightcolored setae that extends to or past the end of the gaster (Fig. 1e,f). Pedicel yellow to brown, flagellum dark brown. Separation between the cubital and subcubital setal lines becomes indistinguishable at approximately half the length of the forewing, near the distal apex of the retinaculum (the longitudinal non-setose region at the very posterior of the forewing extends approximately half the length of the trailing edge of the wing) (Fig. 1g). Ovipositor usually exposed, and flattened laterally, blade-like (Fig. 1e,f).......................................................................... P. xylebori (Fig. 1e–g)   
 - Cuticle smooth both anterior and posterior the carina on the syntergum, and with few setae medially (Figs 1a,b; 2a,b; 3h). Pedicel usually dark brown, similar in color to body and flagellum though can be lighter in some individuals. The cubital and subcubital setal lines of the forewing may become closer together at the distal apex of the retinaculum, but are distinctly separate until near the apex of the trailing edge of the forewing (the longitudinal non-setose region at the very posterior of the forewing extends approximately the entire length of the trailing edge of the wing) (Figs 1d; 3a,d). Ovipositor usually retracted in dry or alcohol preserved specimens, but if visible thin and needle-like (Fig. 1a–c; 2a)....... P. holoholo sp. nov. (Figs 1a–d; 2–3)
