Diagnosis

Metopheltes shares several character states with Opheltes : the presence of a thyridium on the second tergite of the metasoma (Fig. 2c), the absence of a distinct tyloid on the basal flagellomere and a deep groove extending the full length of the mesopleuron (Fig. 3c) ( Townes 1970). This mesopleural character is not unique within Perilissini and occurs also in Priopoda impressa Reshchikov, 2012 ( Reshchikov 2012) and some Westwoodiini ( Wharton et al. 2010). Unlike Opheltes (Fig. 4a) the second maxillary palpomere is not modified in Metopheltes (Fig. 2d) while the frontal carina (a character state previously found only in Opheltes ) is present in Metopheltes clypeoarmatus sp. n. (Fig. 3b), though less developed. Metopheltes also differs from Opheltes by the shape of the propodeum in lateral view: the basal part rounded (elevated at an acute angle in Opheltes ); its apical part comparatively elongate and the apical transverse carina not elevated (Figs 2a, 4b). The median apical ligulate process of the last visible sternite of male is notched apically and laterally (Fig. 5f). The tip of the aedeagus is bent over and ends in an adze-like blade.
