Tiphia (Tiphia) sankutei

T. sankutei differs from T. uruouma in having a long, usually faintly sclerotized spur on the first section of the radius, and in lacking on the intermediate terga conspicuous apical rows of bristle-bearing punctures.

HOLOTYPE.—♂; Buenos Aires Province, Argentina, 15–I–1925 (M. Sankute) (CAS).

MALE.—Front entirely covered with contiguous punctures; with numerous minute secondaries on lower two-thirds. Head width 2.0 times least distance between eyes (2 measured were 2.0, 1.9). Cheek slightly wider than antennal fossa. Mandible without preapical denticle.

Dorsal pronotum with carina sharp and high; bordering sulcus scalariform for its entire length, the cross ridges very short. Lateral pronotum faintly rugulose, without transdiscal escarpment or groove. Mesopleuron on outer disc with numerous moderate-sized punctures separated by distances about equal to their average diameter; secondaries almost absent. Legs black. Hind tibia on inner face with naked streak broadened apically, usually not sharply carinate; sensorium clavate. Tegula not shagreened; with short anterior and posterior marginal grooves not connected at outer apical corner. Forewing with hyaline membrane; first section of radius with backward directed spur extending more than half way across first cubital cell, in 3 or 4 examined only faintly sclerotized; radial cell in lateral extension scarcely equal to second cubital cell, its apex narrow; sectors of second cubital cell in terms of inner sector (itob) are 10:26:18:22.

Dorsal propodeum shallowly reticulate outside areola and on area about as large. Lateral propodeum with moderate numbers of well-separated rugulae present into caudal corner. Posterior propodeum with numerous fine rugulae arising from transverse carina. Tergum 1 without transverse carina; preapical band not impressed, without escarpment on anterior border, about 2 punctures wide. Terga 3 and 4 without encircling escarpments or grossly enlarged punctures; posterior punctures at least medially are far removed from apices and not aligned in a close, regular row. Sternum 5 without lateral denticles.

Length 11.0 to 11.7 mm.

FEMALE.—Unknown.

PARATYPE.—1; same data as holotype (CAS).
