Parahemitaxonus gen.nov.is allied to Pseudohemitaxonus Conde but differs from it in inner tooth of mandible remote from the apical tooth,occipital carina absent,the third antennal segment distinctly longer than the fourth one,hind orbit very narrow,propodeum with a wide but shallow blotch,frons flat and abruptly bent at the line of lateral fovea and claw with a inner tooth. Carinoscutum gen. nov. is also quite similar to Pseudohemitaxonus Conde. Carinoscutum differs from the lattter one in prescutum with a deep and curved transversal furrow which cuts the prescutum into a larger trapezoidal and a smaller triangular area,notaulus discontinued,inner front tibial spur deeply bifurcate,propodeum with a shallow and wide blotch,cross vein of anal cell in front wing distinctly oblique.
