Key to Oriental and Palaearctic species of Zombrus Marshall 

1 Occipital carina at least latero-dorsally present ( Figs 23, 24 View Figure , 44 View Figure ); bristles of fourth hind tarsal segment 0.5–0.6 × as long as hind telotarsus; subgenus Zombrus Marshall, 1897  .............................................................. 7 2

- Occipital carina completely absent ( Fig. 11 View Figure ); bristles of fourth hind tarsal segment approx. 0.4 × as long as hind telotarsus; [hind coxa and femur with dense and long setae; metasomal tergites 4-6 shiny and entirely smooth ( Figs 8 View Figure , 18 View Figure )]; subgenus Trichiobracon Cameron, 1905  ............................................................................. 7

2 Legs and palpi black or dark reddish brown; head and mesosoma with long and conspicuous setae; frons with small medial protuberance; middle tarsus not or slightly shorter than tibia; face sparsely punctate to reticulate-punctate; [long setae of hind tibia erect and distinctly longer than maximum width of tibia]........................... Z. bicolor ( Enderlein, 1912) 

- Legs and palpi pale reddish brown to brownish yellow, but hind tarsus sometimes darkened; head and mesosoma with medium-sized and rather inconspicuous setae; frons with medium-sized medial protuberance; middle tarsus shorter than tibia; face rugose-punctate, rugulose-punctate or reticulate-punctate; [setae of hind tibia variable, frequently medium-sized and about equal to maximum width of tibia].................................................................... 3

3 Second and third metasomal tergites laterally and a transverse patch of fourth–sixth tergites black; pronotal side largely coarsely punctate; apical half of fourth metasomal tergite striate; hind tibia with erect and long setae; [base of fore wing with reddish veins]............................................................ Z. nigrobalteatus (Cameron, 1906) 

- Metasomal tergites entirely brownish yellow; pronotal side largely rugose-crenulate; apical half of fourth metasomal tergite largely smooth; hind tibia with slanted and medium-sized setae................................................. 4

4 Veins of basal third of fore wing dark brown ( Figs 22 View Figure , 29 View Figure ); length of eye in dorsal view approx. twice as long as temple; fourth–sixth metasomal tergites finely punctate basally............................... Z. tricoloricorpus Long  , sp. n.

- Veins of basal third of fore wing yellowish ( Fig. 36 View Figure ); length of eye in dorsal view 1.2–1.6 × temple ( Fig. 44 View Figure ); fourth–sixth metasomal tergites smooth basally........................................................................ 5

5 Pterostigma dark brown basally; length of eye in dorsal view approx. 1.6 × temple; third antennal segment 1.3 × longer than fourth segment; [hind femur 2.7 × longer than its maximum width; marginal cell of hind wing without transverse vein].................................................................................

- Vein m-cu of hind wing gradually merging into vein 2-CU and no posterior stub ( Fig. 37 View Figure ); face largely coarsely reticulatepunctate, remotely punctate laterally ( Fig. 43 View Figure ); hind femur 2.5–2.8 × longer than its maximum width ( Fig. 41 View Figure )....................................................................................... Z. pallidiventris Cameron, 1910

- Pterostigma dark brown ( Figs 7 View Figure , 19 View Figure ); apical half of fore wing mainly or entirely dark brown, at most with pair of yellowish spots; face and base of metasoma brownish yellow or reddish brown; body length 8–14 mm .......................... 8

8 Veins of basal half of fore wing brown ( Figs 1, 7 View Figure ); metasoma dark brown ( Figs 1, 8 View Figure ); hind tibia with long erect setae dorsally, setae twice as long as its maximum width of tibia; [vein M+CU of hind wing 1.2 × as long as vein 1-M].............................................................................................. Z. bicoloricorpus Long  , sp. n.

- Veins of basal half of fore wing yellow ( Figs 10, 19 View Figure ); metasoma brownish yellow ( Fig. 18 View Figure ); hind tibia with medium-sized slanted setae, setae as long as its maximum width of tibia...................................................... 9
