Diagnosis.

This species is morphologically similar to P. gainesvillensis (Florida), P. huachuca (Arizona), and P. liagrantae (Costa Rica), but there are enough morphological differences (see key above for details on how to separate those four species) and disparate geographical distributions (including different ecosystems and considerable variation in altitude) to consider all of them as different. The Canadian species can be separated based on its fore wing vein R1 yellow-white, T3+ yellow-orange on posterior 0.2-0.5, metacoxa dark brown on anterior 0.3, and T2 mostly sculptured (fore wing vein R1 dark brown; metasoma mostly dark brown to black, metacoxa entirely yellow, and T2 mostly smooth on P. liagrantae ).

Description.

Head: mostly black, labrum and mandibles yellow. Flagellomeres: dark brown. Mesosoma: black. Tegula: yellow. Metasoma (dorsally): mostly dark brown, with T3+ yellow-orange on posterior 0.2-0.5. Metacoxa: mostly orange yellow, with black to dark brown spot on anterior 0.3 dorsally. Malar distance: less than 0.2 × eye length. Fore wing areolet: present. T1 sculpture: mostly sculptured. T2 sculpture: mostly smooth. Body length: 3.40-3.50 mm. Fore wing length: 3.40 mm. Ovipositor length: 2.10-2.30 mm. Ocular-ocellar line: 0.14 mm. Interocellar distance: 0.09-0.10 mm. Posterior ocellus diameter: 0.08-0.09 mm. Metacoxa length: 0.80-0.90 mm. Metafemur length: 0.90-1.02 mm. Metatibia length: 1.15-1.28. T1 length/width at posterior margin: 0.47-0.57/ 0.29 mm. T2 length/width at posterior margin: 0.11 mm/ 0.42-0.43 mm.

Distribution.

CANADA, Ontario; UNITED STATES, Florida, Massachusetts. Collected between 55 and 117 m.a.s.l.

Biology.

Unknown.

Molecular data.

The holotype rendered an almost complete DNA barcode (622 base pairs), the sequence page in BOLD is CNSLK014-12. It belongs to BIN BOLD:ADA9820, which contains another sequence, from P. liagrantae (Costa Rica). The two sequences are rather similar (1.73% base pairs difference) but represent different species.

Etymology.

Named after Jayme Sones, Collections Manager of the Centre for Biodiversity Genomics (CBG), University of Guelph, Canada, in appreciation of the extraordinary work she has done for the CBG during the past 15 years, and as a big thanks for her support and help with many braconid loans and other topics over the years.
