1. Vertex very smooth and almost impunctate (fig. 1A, C, F in Shinohara, 2019a); female antenna largely whitish and abdomen with lateral white spots (fig. 1A, B, D, F in Shinohara, 2019a); male with tufts of long golden hairs on abdominal sterna (fig. 1C in Shinohara, 2019a)... Monoxiphia ............................................................. M. harai
– Vertex largely covered with coarse surface microsculpture, or rather smooth but partly coriaceous with sparce large punctures (Fig. 3); female with antenna and abdomen black (Figs 1 A–F, 2); male without tufts of long golden hairs on abdominal sterna. … Konowia …....................................................................................... 2

3. Antenna thick, with flagellomere 2 about 1.5–1.9× longer than broad (Fig. 4 A–J, R–U); forewing with crossvein 2r-m basal to crossvein 2m-cu on vein M and vein 1A narrowly separated from or shortly fused with 2A+3A (Figs 1A, B, F, 6A, C); hind tarsomere 1 long, about 1.1–1.3× length of tarsomeres 2–4 combined (Fig. 6D); valvula 3 (apical sheath) long, about 1.0–1.1× length of valvifer 2 (basal sheath) (Figs 7, 8E, F)............................................................ 4
– Antenna thin, with flagellomere 2 about 2.7–4.4× longer than broad (Fig. 4 K–Q); forewing with crossvein 2r-m usually interstitial with crossvein 2m-cu and vein 1A fused with 2A+3A for a long distance (Figs 1 C–E, 6B); hind tarsomere 1 short, about 1.0× length of tarsomeres 2–4 combined (Fig. 6E); valvula 3 short, about 0.8–1.0× length of valvifer 2 (Fig. 8 A–D)....... 5
