Ettchellsia Cameron, 1909

Ettchellsia Cameron 1909: 208; Baltazar 1961: 219; He 1991: 475; Mita and Shaw 2012: 101. Type species: Ettchellsia piliceps Cameron, 1909 (by monotypy).

Diagnosis.

Posterior ocular orbits with groove and carina present; posterior border of mesopleuron smooth, without a row of foveae; propodeum with unique pattern of longitudinal carinae; forewing fuscous or with fuscous banding pattern; forewing with vein Rs between Rs + M and r-rs tubular for at least a short distance, apical segment of Rs tubular, arched towards stigma, M+ Cu and distal segments of Cu absent or at most spectral; Hind tibia rugose and with erect setae. Additional diagnostic characters for the genus were provided by Shaw (1990b), Vilhelmsen et al. (2010), and Mita and Shaw (2012).

Biology.

No biological data for Ettchellsia species are available; however, these wasps have long been suspected to be idiobiont ectoparasitoids that attack beetle larvae ( Shaw 1990b).

Distribution.

Oriental region.
