Description. General:
Body length of male: 3.05-3.22 mm (n=2). Body length of female: 2.89-3.40 mm (n=2).
Head:
Length between anterior ocellus and posterior ocellar line in frontal view: less than 0.5 times POL. Striae within ocellar triangle: dense (greater than 20). Vertex sculpture between inner orbit and posterior ocellus: smooth or with few faint striae. Frontal sculpture between inner orbit and central keel: with few (4-5) striae, striae limited to upper half of frons. Submedial ventral area of head anterior to fossa: longitudinally striate throughout. Orbital carina: absent. Sculpture of malar region: longitudinally striate or with few faint striae.
Antenna:
Color of female antenna: A1-A7 brown, A8-A12 dark brown to black, in some antennae sequentially darker from scape to apex. Female outer lateral apex of scape: sharply pointed. Claval shape: apical margin of A9-A11 straight, antennomeres distinctly separated. Color of male antenna: dark brown to black throughout.
Mesosoma:
Sculpture on medial lobe of mesoscutum: longitudinally striate. Setation of medial lobe of mesoscutum: sparse to glabrous. Notaulus: present. Notaulus form: mesal margin arched, lateral margin straight. Length of notaulus: abbreviated, clearly not reaching anterior margin of mesoscutum. Width of notaulus anteriorly: narrowed anteriorly. Pilosity of notaulus: absent. Number of lateral carinae on mesoscutum: 2. Medial carina of mesoscutum: absent. Parapsidal line: absent or faint. Posterior scutellar sulcus: complete. Setation of posterior half of ventral metapleural area: sparse (less than 25 setae). Metascutellum size: wide, metanotum lateral to metascutellum reduced, with 0-3 foveae. Sculpture on ventral metapleural area: strongly reticulate rugose with foveolae. Median propodeal sulcus: narrow throughout length. Sculpture of submedian propodeal field: smooth throughout or with few faint striae. Posterolateral margin of propodeum: longitudinally striate laterally, rugulose posteriorly. Color of legs: coxae dark brown to black, otherwise yellow in female and brown in male.
Wings:
Postmarginal vein: absent. Fore wing: hyaline.
Metasoma:
Sculpture on T1: longitudinally striate throughout. Sublateral carina on T2-T4: absent. Sculpture on T2-T4: longitudinally striate throughout, uniformly setigerous punctate within interstices on T3-T4.
Diagnosis.
Platyscelio striga is unique in the genus in having two lateral carinae on the mesoscutum (Fig. 63), and no sublateral carinae on T2-T4 (Figs 61, 64).
Etymology.
The epithet striga, Latin for swath, refers to the distinct striae of the frons.
