VI. Subfamily Thaumatodryininae Olmi, 1984

Thaumatodryininae Olmi 1984: 682 ; Tribull 2015: 20.

Type genus. Thaumatodryinus R. Perkins 1905 , by monotypy and original designation.

Diagnosis. ♀ ( Figs 156C, D View FIGURE 156 ): fully winged ( Figs 156C, D View FIGURE 156 ); forewing with three cells enclosed by pigmented veins (C, R and 1Cu) ( Figs 156C, D View FIGURE 156 ); usually in forewing also 2Cu cell completely enclosed by pigmented veins; protarsus chelate ( Figs 156C, D View FIGURE 156 ); chela with a rudimentary claw ( Fig. 158A View FIGURE 158 ); antenna with tufts of long setae (“tiloïdes” of Benoit 1954) on antennomeres 5–10 (antennomere 10 with two tufts) ( Figs 156C, D View FIGURE 156 , 157C View FIGURE 157 ); pronotal tubercle reaching tegula; mandible with four teeth becoming regularly progressively larger from dorsal to ventral tooth ( Fig. 6B View FIGURE 6 ); occipital carina complete; antenna without ADOs; palpal formula 6/3; tibial spurs 1/1/2. ♂ ( Figs 157A, B View FIGURE 157 ): fully winged; forewing with three cells enclosed by pigmented veins (C, R and 1Cu) ( Figs 157A, B View FIGURE 157 ); forewing with PostabR1 as long as, or longer than pterostigma ( Figs 157A, B View FIGURE 157 ); occipital carina complete; paramere without inner branch wrapping penis ( Figs 159A, C View FIGURE 159 ); mandible usually with four teeth becoming regularly progressively larger from dorsal to ventral tooth ( Fig. 6B View FIGURE 6 ); occasionally mandible with four teeth of different length; never quadridentate mandibles including one intermediate rudimentary tooth; notauli always separated at posterior margin of mesoscutum; minimum distance between notauli as long as, or longer than greatest breadth of lateral ocelli; pal- pal formula 6/3; hypopygium not umbrella-shaped (as in Fig. 8H View FIGURE 8 ); tibial spurs 1/1/2.

Distribution. Worldwide, except Palaearctic region. Brues (1923, 1933) described three fossil species of Thau- matodryinus from Baltic amber; they are now attributed to Harpactosphecion Haupt.

Hosts. Flatidae (Guglielmino et al. 2013).

World species. 33 species are known, ten in the Afrotropical region.

World genera. One genus is known.

Remarks. After the original description by Olmi (1984), the subfamily Thaumatodryininae was considered a junior synonym of Dryininae Haliday 1833 (Xu et al. 2013; Olmi & Virla 2014). Based on molecular analysis, Tribull (2015) resurrected Thaumatodryininae to establish the monophyly of Dryininae and retain Gonatopodinae as a separate subfamily. The defined morphological synapomorphy for Thaumatodryininae is the presence of tufts of long setae on antennomeres 5–10.
