APPENDIX
A Hybrid Holotype?
No specimen was found to match the holotype of P. pictipes, which is, however, a clear intermediate between P. albiceps Elliott and P. rufoornatus (Cam.) [See table below]
| Hybrid (?) characters in the holotype of P. pictipes Roman. | |
| Typical for P. rufoornatus | Typical for P. albiceps |
| Hind coxa short | No yellow marks on face |
| Hind femur short and wide | Temple short |
| Pygidial sulcus deeply notched | Scutellum punctate-foveolate |
| Pterostigma apically blunt | Propodeum with large areolations |
| Gaster long | - |
| Overal size small | - |
The observed hind leg proportions are incompatible with those of P. albiceps, but typical for P. rufoornatus. The long gaster, similar vertex/temple sculpturing, and small size, are also characteristic of P. rufoornatus. However, crucial diagnostic characters of this species are "replaced" by typical characters for P. albiceps, as the strong sculpturing of the scutellum, unicolor face, narrow gena, etc.
This strong ambiguity, and the absence of similar specimens, make it unlikely that P. pictipes is
either a synonym or a distinct species.
One possibility is that this holotype is a hybrid of the two species discussed above. This is at least
geographically and morphologically possible, as these species are sympatric and share structurally
identical genitalia.
