Zaglyptus Förster, 1869 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.
