Diagnosis. Both sexes: body usually black or dark rufous, mesosoma sometimes orange-red, FW hyaline with two dark fasciae ( Figs 1A, 1F View FIGURE 1 , 3A, 3F View FIGURE 3 , 5A View FIGURE 5 ). Vertex crest slightly above uppermost portion of occipital carina ( Figs 1B View FIGURE 1 , 3B View FIGURE 3 , 5B View FIGURE 5 ); outer orbit sharply grooved; gena narrow ( Figs 1C View FIGURE 1 , 3C View FIGURE 3 , 5C View FIGURE 5 ); labrum partially exposed ( Fig. 1D View FIGURE 1 ); postnotum extremely short ( Figs 1C View FIGURE 1 , 3C View FIGURE 3 , 5C View FIGURE 5 ); in dorsal view, propodeum coarsely and irregularly reticulate-rugose, and with a pair of subparallel longitudinal carinae medially ( Fig. 2G View FIGURE 2 ); pterostigma large ( Figs 1F View FIGURE 1 , 3F View FIGURE 3 ); mid and hind tibial spurs ivory-white ( Figs 1A View FIGURE 1 , 3A View FIGURE 3 , 5A View FIGURE 5 ); protarsus without tarsal comb, all tarsomere 5 without ventral spines, all tarsal claws bifid. Male: flagellomeres with elliptic depressed placoid sensilla ( Figs 1G, 1H View FIGURE 1 , 3G, 3H View FIGURE 3 ); inner fore tarsal claws conspicuously modified ( Fig. 1L View FIGURE 1 ); posterolateral of S6 with pair of large and rod-shape hook pointed at middle ( Figs 1I View FIGURE 1 , 3I View FIGURE 3 ); exposed portion of SGP triangular or arrowhead-shaped, sometimes with long parallel side ( Figs 1K View FIGURE 1 , 3K View FIGURE 3 ); genitalia with paramere very short ( Figs 4A, 4D View FIGURE 4 ); parapenial lobe broad and sinuated, pointed at apex ( Figs 4C, 4F View FIGURE 4 ); volsella with setae, apically rounded; aedeagus broad, parallel-sided for most part ( Figs 4B, 4E View FIGURE 4 ).

Additional characters. Both sexes: mid and hind tibiae ventrally with 2 rows of brown, small spines; all tarsomeres 1–3 with 3 rows of ventral spines, tarsal plantulae present. Male: S6 posteriorly inverted-V-shaped or arcuately emarginated ( Figs 1I View FIGURE 1 , 3I View FIGURE 3 ); sides of S4 and S5 with more or less setae.

Biology. There are currently no records of biological information for this genus. From our observation and collection experience, we know that representatives of the genus are active in grasslands, fields, and sunny places in woodlands and rainforests.

Distribution. The Oriental Region: China ( Taiwan, Yunnan, Guangxi), Thailand, and Malaysia ( Shimizu et al. 2021 and current data). The genus is newly recorded from China mainland.
