Pronotum nearly equal or little shorter than fore femora; median carina faintly indicated in prozona, absent in metazona; lateral carina distinct in metazona, faintly indicated on prozona ( Fig. 2 View FIGURE 2 GHJ; Fig. 4D View FIGURE 4 ). Prosternum with a pair of slender and short spiniform processes ( Fig. 4C View FIGURE 4 ). Mesosternum and metasternum both with a pair of triangular lobe-shaped processes, acute in mesosternum and obtuse in metasternum ( Fig. 4C View FIGURE 4 ). Male tegmina mesopterous, far exceed pronotum ( Fig. 2 View FIGURE 2 GH; Fig. 3 View FIGURE 3 FG; Fig. 5 View FIGURE 5 AB). Female tegmina micropterous, slightly longer than pronotum ( Fig. 2J View FIGURE 2 ; Fig. 5 View FIGURE 5 CD). Hind wings micropterous ( Fig. 4 View FIGURE 4 FG). Fore tibiae dorsally without internal spines, with an ex- ternal apical spine; middle tibiae dorsally with spines on both sides, with a internal apical spine. Male tenth tergite with a pair of pileous round blunt lobes in posterior margin ( Fig. 3A View FIGURE 3 ). Male cercus conical, strongly incurved at the middle, apices acute, with a spiniform inner tooth placed in basal area ( Fig. 4 View FIGURE 4 AB); subgenital plate with a deep median excision on posterior margin, styli evident ( Fig. 3C View FIGURE 3 ). Female subgenital plate with a weak median excision on posterior margin ( Fig. 3D View FIGURE 3 ); ovipositor downcurved ( Fig. 3E View FIGURE 3 ).
This new genus significantly different from Uvarovina Ramme and Bienkoxenus Cejchan by: prosternum with a pair of spiniform processes ( Fig. 4C View FIGURE 4 ). Furthermore, this new genus differs from Anatlanticus Bey-Bienko , Mongolodectes Bey-Bienko , Paratlanticus Ramme and Kansua Uvarov by: male cercus strongly incurved at the middle, apices acute, and with an inner tooth placed in basal area ( Fig. 4 View FIGURE 4 AB); different from Ceraeocercus Uvarov by: male cercus with an inner tooth placed in basal area ( Fig. 4 View FIGURE 4 AB); and different from Atlanticus Scudder by: lateral carina of pronotum not all distinct, median carina faintly indicated on prozona, and shorter than fore femora ( Fig. 2 View FIGURE 2 GHJ; Fig. 4D View FIGURE 4 ); female tegmina slightly longer than pronotum ( Fig. 2J View FIGURE 2 ; Fig. 5 View FIGURE 5 CD).
