Genus Parancistrocerus Bequaert, 1925

Parancistrocerus Bequaert 1925: 64 ; Carpenter 1986: 79; van der Vecht & Carpenter 1990: 42; Giordani Soika 1994: 152; Girish Kumar et al. 2016: 137 .

Type species Odynerus fulvipes de Saussure, 1855 [= O. “ flavipes Fabricius” sensu de Saussure, 1852, non Uespa flavipes Fabricius, 1775], by original designation.

Diagnosis. T1 usually with transverse carina separating vertical face from dorsal face in Oriental species ( Figs 4 , 10 , 18 , 20 , 29 , 36, 62); withT2 smooth basally, forming acarinarium beneath the apex of T1 that is often filled with mites ( Figs 7 , 29 ) (often concealed, tergum should be bent backwards to expose acarinarium); anterior sloping face of pronotum medially with two connected or separated, deeply impressed fovea ( Figs 9 , 16 , 22 , 28 , 35, 40, 56); propodeum with submarginal carina produced into pointed lamella apically, valvula enlarged and free posteriorly from submarginal carina; metanotum without tubercles; forewing with second submarginal cell not petiolate; metasoma sessile ( Giordani Soika 1994; Girish Kumar et al. 2016).

Distribution. Nearctic, Neotropical, Oriental and Palaearctic Regions.
