Diagnosis.

Medium to small wasps, 5–13 mm. Black, terminal gastral segments sometimes red; whitish marks on mandible, clypeus, frontal platform, pronotal tubercle, tegula, and leg. Inner margin of mandible with teeth. Clypeus median carina often present. Antenna filiform, slender and long; 12 segments in female, 13 segments in male; antennal sockets nearly contiguous, covered by U-shaped lamella. Frontal line usually indicated, but weak and intermittent; vertex arched above eyes; maxillary palpi slender, labial palpi short and stout; thorax covered with silvery pubescence, pronotal collar shorter than scutum; scutum notauli conspicuous and nearly complete, admedian line absent, parapsidal line present, scutellum with a transverse furrow anteriorly; mesopleuron with omaulus, anteroventral remnant of episternal sulcus; acetabular carina incomplete; sternaulus and scrobal sulcus conspicuous to inconspicuous; propodeum with U-shaped enclosure, multicarinate to areolate, propodeum setae dense and long; petiole and pygidium absent. T 1 anterior inclination with shallow oval depression, usually impunctate, S 1 appears humped basally and medially, and forms lamella apically, S 2 with deep groove at base. Forewing with three submarginal cells, media diverging after cu-a; hindwing jugal lobe present but small, media diverging before cu-a ( Bohart and Menke 1976).

Biology.

Larve of D. corniculus ( Spinola, 1807) have been described by Maneval (1939) and Evans (1959). Nests of Dolichurus are sealed with leaves and grass debris, primarily in stalks and rock crevices, or buried in holes 7–8 cm deep in the ground ( Ferton 1895). Dolichurus greenei Rohwer, 1916 , D. corniculus ( Spinola, 1807) , and D. turanicus Gussakovskij, 1940 prey on species of Ectobiidae ( Grandi 1931, Krombein 1955); D. corniculus ( Spinola, 1807) prey on species of Blattidae ( Handlirsch 1889) ; and D. haemorrhous A. Costa, 1886 prey on species of Blattellidae ( Adlerz 1904) .
