Zaglyptus Förster, 1869 . Verh. Naturh. Ver. Rheinlande 25: 166. Type-species: Polysphincta varipes Gravenhorst , by subsequent designation, Woldstedt, 1877: 17.

Diagnosis. Face with a pair of furrows arising from supraclypeal suture; clypeus strongly convex, apical margin thin, broadly concave medially; mandible stout, swollen near apex, pointed at tip, upper tooth longer than lower; palpi formula 5:4; occipital carina complete, mediodorsally more or less convex; mesopleural suture weak but quite distinctly angled centrally; submetapleural carina complete or present only anteriorly; propodeum with paired posterolateral swellings; claws of female with a pointed basal lobe; fore wing lacking vein 3 rs-m; metasomal tergites 2–5 (sometimes also tergite 6) each with paired lateral swellings; ovipositor lower valve with distinct teeth, most proximal usually with an elongate free tip; male with subgenital plate subquadrate, posteriorly truncate ( Townes 1969; Gauld 1991).

Zaglyptus species are believed to attack nest-making spiders ( Baltazar 1961; Gupta 1961; Townes 1969; Gauld 1984). The larvae develop on paralysed, mature spiders and their eggs ( Fitton et al. 1988). However, there are no host records from Vietnam and most Zaglyptus species remain unknown biologically.
