Diagnosis. Physotarsus polleti Reshchikov and Sääksjärvi sp. n. can be distinguished from all other described species of Physotarsus by the combination of the following characters: 1) black scape and flagellum (Fig. 15), 2) long malar space (1.2 times basal mandible width, Fig. 15), 3) yellow temple, yellow whitish first metasomal tergite and entirely black hind legs (Fig. 16).
Description. Female. Body length 8–9 mm. Antennae with 31 flagellomeres each. Scapus 0.8 times as broad as long. Head narrowed behind the eyes, shining. Maximal length of temple 0.9 times transverse eye diameter; minimal length of temple 0.72 times transverse eye diameter. Face 1.16 times height of eye; moderately flat, with bulge (Fig. 15). Face sparsely covered with long red setae. Interantennal area flat. Clypeus separated from face by transverse groove; projecting anteriorly, sharp laterally and with obtuse medially. Clypeus about 2.5 times as broad as long. Clypeal foveae not large, pointed laterally. Interantennal distance about 2.25 times the distance between lateral ocelli. Lateral ocelli separated by about 0.57 times their widest diameter from each other and about 2.25 times their widest diameter from eye margin. Malar space 1.2 times basal mandible width. Occipital carina present on ventral part of head. Lower mandible tooth longer than upper.
Mesosoma smooth, shining, without punctures. Pronotum smooth, impunctate, shining. Mesoscutum shining and impunctate. Notaulus not distinctly impressed at base but distinctly follow far beyond. Epicnemial carina strongly turning towards anterior margin of mesopleuron. Mesopleuron impunctate, shining. Claws pectinate with height teeth. Hind tarsi 1.07 times as long as hind tibia; each article of hind tarsi length ratio 25:8:5:3:5. Fore wing stigma about 5 times longer than wide. Radius intercepted stigma before its middle. Second recurrent vein with a single bulla. Nervellus intercepted below middle, distal abscissa of cubital vein of hind wing turned towards hind edge of wing. Nervulus prefurcal. Propodeum without carinae.
Metasoma shining. First metasomal tergite 2.3 times as long as apically wide; without shallow median longitudinal impression and longitudinal carinae. Second metasomal tergite elongate. Ovipositor straight, as long as height of metasoma apically.
Color. Yellow red, antenna, head beyond antenna, mesoscutum and mesopleuron, hind legs, apical segment of middle tarsi, and pterostigma black (Fig. 16). Fore wing yellow, infuscate apically (Fig. 16).
Material. Holotype female, Ecuador, Cajanuma, Podocarpus N.P., 3000m, 16.ii.–05.iii.2009, Malaise trap, leg. M. Pollet & A. Breakeleer, RBINS; Paratype female: the same location than Holotype specimen, RBINS.
Distribution. Ecuador.
Etymology. The species epithet refers to Dr. Marc Pollet who collected the specimens. Dr. Pollet has sampled insects in many Central and South American locations and kindly distributed his samples to other taxonomists.
