Type: Pulchrisolia maculata Szabo , by monotypy and original designation); Masner 1964 : 11 (treated as a synonym of Sceliotrachelus Brues); Masner and Huggert 1989 : 29, 108 (keyed, description, diagnosis, species list); Vlug 1995 : 73 (cataloged, catalog of world species); Veenakumari et al. 2019 : 453 (key to genera of the Isolia -cluster, keyed). Description. Coloration: yellow; orange; light to dark red; brown to brownish-black. Antennal formula: 10-10. Male antennae: filiform. Clava: subcompact. Number of clavomeres: 3. Arrangement of setae on ventral surface of clavomeres: chevron-shaped leading to posterior-most papillary sensillum. Sensillar formula of clavomeres: A10-A8/1-2-2. Position of lateral ocellus: remote from inner margin of compound eye by> 3 ocellar diameters. Hyperoccipital carina: present. Frontal ledge: present; absent. Interantennal process: present. Shape of clypeus: ovoid, abruptly widening below ventral surface of interantennal process. Labrum: concealed by clypeus. Facial striae: absent. Malar striae: absent. Malar sulcus: absent. Epomium: incomplete dorsally. Notaulus: present; absent. Anterior admedian depression: present; absent. Axilla: absent. Axillular carina: present, potentially fused with transaxillar carina, sometimes with the posterior margin projecting over metanotal trough. Sculpture of anterior margin of mesoscutellum: smooth; weakly crenulate. Scutoscutellar sulcus: undifferentiated from transcutal articulation. Posterior mesoscutellar sulcus: undifferentiated from mesoscutellar disc. Metascutellum: differentiated from metanotal trough by metascutellar carinae. Sculpture of metascutellum: smooth. Sculpture of metanotal trough: smooth. Netrion: absent. Sculpture of dorsal mesopleuron: transversely ridged. Transepisternal line: absent. Mesopleural carina: present. Foamy structures on metapleuron: present posteriorly. Metapleural carina: concealed by foamy structures. R (submarginal vein) of fore wing: present, <1/10 length of fore wing. Marginal cilia of fore wing: present; absent. Shape of fore and hind wing microtrichia: scale-like pegs, some nearly as wide as long. Shape of T1 in dorsal view: transverse. Foamy structures on T1: present anterolaterally. Foamy structures on S1: present, transverse, sometimes projecting between hind coxae. Transverse felt field on S2: absent. Tibial spur formula: 1-2-2. Protibial spur: combed. Setation of dorsal metatibia: present as linear tract of dense setae. Diagnosis. Species of Pulchrisolia may be diagnosed from other platygastroids by the following combination of characters: fore wing with incredibly short, tubular R vein terminating in a knob and at least some microtrichia of the fore and hind wings in the form of short, scale-like pegs. The coloration of the adult (most species are yellow, orange, red, or a combination thereof); frontal ledge on the lower frons; bilobed, protuberant interantennal process; and tract of dense setae on the metatibia are additional characters that may aid in the recognition of the genus.
