Type species. Thaumatodryinus koebelei R. Perkins, 1905 , by original designation.

Diagnosis. Female ( Plates 69E , 73A ): fully winged ( Plate 73A ); mandible with four teeth progressing larger from anterior one to posterior (as in plate 3D); occipital carina complete; palpal formula 6/3; antenna without rhinaria, with tufts of long hairs on segments 5–10 (segment 10 with two tufts) ( Plates 69E , 70A , 73A ); pronotal tubercle reaching tegula; fore wing with three cells enclosed by pigmented veins (costal, median and submedian) ( Plates 69E , 73A ); usually in fore wing also first brachial cell is completely enclosed by pigmented veins (see plate 2F in Olmi, 1984); protarsus chelate ( Plates 69E , 73A ); chela with rudimentary claw ( Plate 73B ); tibial spurs 1/1/2. Male ( Plate 72A ): fully winged ( Plate 72A ); occipital carina complete; mandible usually with four teeth progressing larger from anterior one to posterior (as in plate 3D); occasionally mandible with four teeth differently long; never quadridentate mandible with an intermediate rudimentary tooth; palpal formula 6/3; notauli always separated at posterior margin of scutum; minimum distance between notauli as long as, or longer than greatest breadth of posterior ocelli; fore wing with three cells enclosed by pigmented veins (costal, median and submedian) ( Plate 72A ); fore wing with metacarpus as long as, or longer than pterostigma ( Plate 72A ); paramere without inner branch wrapping penis ( Plate 71A – C ); tibial spurs 1/1/2.

Distribution. Worldwide, except Palaearctic. Brues (1923, 1933) described three fossil species of Thaumatodryinus from Baltic amber; they are now attributed to Harpactosphecion Haupt 1944 .

Hosts. Flatidae ( Guglielmino & Olmi, 1997) .

World species. Thirty species are known, eleven in the Oriental region.
