(Figs 12 A–D)
Diagnosis. This species falls in a group with the ocellus crossed by the supra-torular line and the marginal cell shorter than in P. m al ar i s sp. nov. and related species. It is related by the long F1 to P. albinervis sp. nov. from which it differs by the propodeum swollen behind the spiracle and the flat clypeus.
Description. Holotype, ♂. Body length 9.9 mm (paratypes 8.0– 9.7 mm). Color. Brown with head darker.
Head. 1.2 × wider than high in frontal view; wider in dorsal view than width of scutum between tegulae (6.9:6.6). OOD 1.3 × diameter of lateral ocellus; POD 1.2 × OOD. Antennocular distance 0.7 × diameter of torulus; interantennal distance 3.3 × antennocular distance. Vertex weakly reticulated, weakly striate, moderately punctate between of lateral ocelli (punctures separated by 1.5 × puncture diameter). Torulus closer to lateral ocellus than to clypeus (1.0:2.2). Lateral ocelli in frontal view below upper margin of head. Median ocellus crossed by supratorular line (Fig. 12 A). Genal carina present, distinct. Lengths of area between preoccipital carina and suboral swelling subequal (0.9:1.0); this area without median, longitudinal carina; lower area of genal bridge close to mandible articulation without carinae or punctures (Fig. 12 B). Malar area longer than apical width of F1 (1.3:0.7); striate anteriorly. Supraclypeal area with lateral striae extending to about upper level of torulus, rounded in lateral view (Fig. 12 C). Epistomal suture evident. Clypeus 1.4 × wider than high, basal area punctate with lateral striae joining medially; apically not truncate. Proportional length of segments of maxillary palp, from base to apex: 8:9:15:18:13:14. Scape without swelling or projection. F1 4.8 × as long as apical width, subequal to scape and pedicel combined (2.4:2.3).
Mesosoma. Area anterior to pronotal lobe with weak striae; pronotal lateral carina distinct, forming lower pocket. Notaulus weakly marked, as long as admedian line. Anterior area of scutum scarcely punctate around the notauli. Propleuron and mesopleuron scarcely punctate. Metapostnotum with fine striae reaching to posterior margin. Propodeum transverse, swollen behind spiracle; without carina anterior to spiracle. Fore wing: marginal cell with anterior margin 2 × as long as posterior margin; length of vein Rs3 longer than length of Rs4 (2.2:1.9); vein M separated from cu-a by 0.3 × length of cu-a; discal cell rectangular. Hind wing: veins M and cu-a interstitial. Protarsomere 1 with three outer lateral spines. Metatarsomere 1 1.9 × as long as mesotarsomere 1; inner metatibial spur 1.5 × as long as outer spur.
Metasoma. T7 triangular; apically with a small polished area. Genitalia as in Fig. 12 D.
Examined material. Holotype, ♂. ARGENTINA, Mendoza, 10 km N de Uspallata, 14.II.1966, col Willink, Stange (IFML). The following are paratypes: 2 ♂, same data of holotype, (IFML); 6 ♂, Uspallata, 10 km w.r. Chile, 16.II.1966, col Stange, Willink (IFML). San Juan, 2 ♂, Camino Paso Agua Negra 2600 m a.s.l., 28.I.1992, col Roig-Alsina (MACN).
Distribution. Argentina (Mendoza, San Juan).
Etymology. The specific epithet refers to the flat clypeus of the species.
