P. juanensis n. sp., is recognised by: jl and marginal podonotal setae, except s2, plumose; setae Zx present; setae R2-R7smooth and spine like setae; RI pubescent; setae S2 smooth and rest o opisthonotal setae plumose; gdZl antiaxial to ZI-22; gdZ3 antiaxial to 23-24: gdZ4 in line Z4-S5 and opisthonotal pits absent. P. escalai n. sp., is recognised by: podonotal setae pubescent except j5; al1 opisthonotal setae pubescent; setae Jl-Jx, Z1-Z4 and S245 on dorsal opisthonotal "hunchs"; gdZ6 anterior to Z1;gdZI antiaxial to S2; gdZ3 paraxial to 22-23, gdZ4 paraxial and posterior to S5 and opisthonotal pits absent. |
